Title: Anti-lag launch and no-lift-shift secrets inside
Post by: julex on May 12, 2011, 06:35:20 PM
Disclaimer:

The code was found in certain canadian tuner file and is 100% working since I drove the car with the features enabled.

Here is the secret to Anti-lag launch and no lift shift. To remind everyone, the anti lag is a mode of operation where ECU interrupts spark every so many ignition cycles as long as the RPM are above set limit causing previously unburned fuel to burn in manifold as soon as RPMs fall and mixture ignites. This results in turbos spooling while the engine doesn't raise RPMs while you sit at the strip waiting for lunch.

The no lift shift kicks in when you press a clutch and is active for a preset amount of time. I am not sure when the spark is provided but expert looking at the code example should tell if this is at certain RPMs that are stored as soon as you hit the clutch or just every N otto cycles.

The M-box bin has alterations in three spots and there also are three DWORD variables stored in EEPROM space for Speed Threshold, Launch RPM and time duration of anti-lag for spots.

I need somebody to alter the assembly code to access currently unused three Dword addresses (your choice) in calibration map space where we can establish three new scalars for the three variables needed to operate the mode properly.

Once this is figured out, the anti lag can for launch control can be controlled by two means:

1) speed, set to 0 and it doesn't work, anthing above 0 works like standard launch control
2) RPM, set it high enough (10,000) and it will never reach the threshold to cut spark

No-Lift shift can be controlled in one way:

1) time value in ms, set to 0 to disable, otherwise it interrupts spark for a preset amount of time after pressing clutch.

We can also alter and improve he behavior of this by ensuring cluch pedal is pressed in both modes (why would you like to launch control without cluthc pressed) and change the behavior of no lift shift to interrupt spark for a given amount of time mask AND only when clutch is still pressed.  c

Now, somebody handy with IDA/hex editor please make it work with alternative memory locations so we can enjoy this feature.

Julex, thanks for sharing what you found. Would you mind telling us which tuner this is from so credit is give where credit is due?

I think it is fine to post what Julex has found. Normally this information is traded secretly for money, here it is posted publicly for free.

Lets not turn this thread into a "what is stealing" thread. If you want to discuss what is stealing, please use this thread: http://www.nefariousmotorsports.com/forum/index.php/topic,609.0.html

There is more information missing. Im sure they change fuel/timing maps.

I can already get 0.5bar on stock 2step on a 1.8T with just some timing tweaks  ;)

I'm sure you're right, but that information is discussed in depth in other threads. The really interesting stuff is the specific areas Julex has identified used to cut ignition without closing the throttle (right?). This is new to me and I suspect many of us.

Nice work Julex.

Im not saying this isn't better than what I have, Im just saying there has to be MORE to it then just this routine. Unless the launch control is a little crude and just cuts spark.  ;)

Here you go... Patched but not checksummed.

FYI, I think the reason matchew was asking for more lines may have been because he thought you accidentally cut off the end of the new subroutine. There seems to be some more code in your file at 000ffac0h as compared to stock. Do you know what this is?

This routine simply manipulates the spark dwell routine.

Care to share?

I think I can port this over to 06A906032RN (1.8T AWP) without too many issues and share the BIN :)


I apologize  :-*, I assumed the rest is stock but it is not! I simply initially compared two tune files, one with the option enabled, the other with is disabled, otherwise identical. The software in question was simply adding the code I initially posted when feature was enabled.

That 100% will not work

You can not simply copy code from one file to another.

You found the correct routine to jump out of though.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: DJGonzo on May 15, 2011, 09:06:42 PM
Finding the routine is easy. On any ME7 file, go to end of file and search up for "D7 40 06 02 03 F8". First match is the correct routine.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: matchew on May 15, 2011, 09:18:47 PM
In the file that you wish to add this code to you need to find certain variables, and apply them to this routine.

The ram address used for dwell time is easy, as it is contained with in the routine that the original code writer jumped out of.

You need to find the ram address of vehicle speed and engine speed

You need to understand that the eeprom is being accessed by this new routine, it looks at 3 address'


Title: Re: Anti-lag launch and no-lift-shift secrets inside

Seems simple enough (if we can find the addresses).

Can you identify the addresses in the added routine?

Is this routine always at the same address? I pulled a file from ME7.5 from the same tuner and can't find this.

By the way does anyone here recognize this signature?

"ERCSU V1.1.6 SAB_C16x (c)ETAS Jul 24 1999"

This is the identification of the realtime OS (ERCOS) made by the company ETAS, it  has nothing to do
with a tuner. Normally this states as date "Jul 24 1997", I guess you have just mistyped the year.

Hi Julex,

The function at 8FFA60 gets called each 20ms after computation of the closing time (tsrldyn) was done.
To interrupt the ignition, the closing time is just set to 0.  Does this way of cutting the ignition
induce any problems?  E.g. DTC's raised or unburned fuel that kills your cats (if they are still present)?

The original function implements the following pseudo code:

function_8FFA60()
{
  // Anti-Lag
  if (vehicleSpeed < ThresholdSpeed && engineRpm > ThresholdRpm)
  {
    closingTime = 0;                // Interrupt ignition
  }

  // No-Lift-Shift
  if (! noLiftShift_active)
  {
    // NoLiftShift is inactive
    if (cond_clutchPressed)
    {
      noLiftShift_active = TRUE;
    }
  }
  else
  {
    // NoLiftShift is active
    if (counter_NoLiftShift < ThresholdCounter)
    {
      closingTime = 0;            // Interrupt ignition
      counter_NoLiftShift++;
    }
    else
    {
      if (! cond_clutchPressed)
      {
        counter_NoLiftShift = 0;
        noLiftShift_active = FALSE;
      }
    }
  }
}


Find attached a stock Mbox binary with inserted AntiLag&NoLiftShift function (now located at 88'E800).
I made following modifications to the original function:
1. the three threshold values are read from parameter space in flash.
2. Anti-Lag is only active when the clutch is pressed.
3. NoLiftShift stops cutting ignition immediately when the clutch is released,
   even if the delay counter is still running.

Also an XDF with the description of the used parameters/thresholds is attached,
so the parameters can be edited quite easily.

Right.
Well this is the thread where the OP posted the code he took that I wrote for my customers, and then asked someone more capable/less lazy than him to patch so he could use it in other files. It is not something put out there by bosch, it is not harmless either.

What do you think about that?

I guess I am asking what you think about this.
Should people be posting other individual's work on here so they can have it patched for reuse elsewhere?

Is that what the forum is for?

It is not just copying some maps or tuning that are massaged bosch code anyway.
Not thrilled about the whole thing, that's for sure.

Post by: Tony@NefMoto on May 17, 2011, 12:01:19 PM
Honestly, this code was going to be copied from Eurodyne at one point or another. Normally this is done secretly in private and often includes the exchange of money.

If this modification is openly credited to Eurodyne and the consensus is that they know what they are doing, then hopefully that will drive additional business to them.

If skilled people here are interested in improving this code modification, then I think it would be great if the community could add to what Eurodyne has done, and maybe they would even add it to their future revisions.

I don't mean to be a jerk, but it's not going to be possible to keep a cat in the bag forever. The tuning industry needs to find a way to benefit from this, otherwise one eBay tuner can destroy the business of all professional tuners.

Certainly I think it would great to identify this as Eurodynes modification, and if possible create a way to identify this code change in a tuned file.

I really hope that there is a way to turn the release of this modification into a positive thing for the tuning community and Eurodyne.

Honestly, this code was going to be copied from Eurodyne at one point or another.

In particular, reverse engineering compiled code is older than pretty much every poster here. Nothing new.... and fairly difficult to get legal monopoly protection for if
1) the "source" isn't copied
2) all there is is a small section of bytes *patched* into somebody else's binary such that the "substantial similarity" test passes more readily on the *original* binary that isn't owned by the creator of the initial binary patch.

Here is something to think about.

No one disputes that Linux is a more secure operating system than Windows and Mac OS. The reason it is more secure, is because there are countless people pouring over the code in Linux to make it better. In Linux all the bugs are fixed before anyone can do serious damage exploiting them. In Windows and Mac OS people are not allowed to find bugs in the code, and Microsoft and Apple scare people into not releasing the details of bugs for fear they are exploited.

Something also to keep in mind is that Linux makes Windows and Mac OS better. If Linux wasn't there constantly making itself better, then Microsoft and Apple could keep selling the same software every year without making it better.

Not really. If you go a few years back, Linux wasn't really too user intuitive.
A better competitor to Windows would be Mac OS instead of Linux.

Also Windows is the de-facto mostly due to piracy. See here:

Right.
Well this is the thread where the OP posted the code he took that I wrote for my customers, and then asked someone more capable/less lazy than him to patch so he could use it in other files. It is not something put out there by bosch, it is not harmless either.

What do you think about that?

So are you saying it's ok for you (or whoever wrote the code for you) to hack/patch Bosch's original software, but it's not ok for others to do the same?

Because that's what it sounds like.

I agree it is ethically questionable to simply cut and paste the patch into a different binary (without understanding what it does).

The ethics of reverse engineering aren't as cut and dried. Every programmer who has EVER released a binary of any kind understands those risks, and understands there are limited legal avenues to prevent it.

Better to have an open discussion of the technology than whinge about who owns what, in the long run.

[Awesome stuff]

Awesome. I will give it a whirl when I have a minute.

The improvements are exactly the shortcomings I didn't like about the original implementation. There was no point anti-lagging with clutch not pressed (as you weren't in a gear obviously) and rigid timer with no other means to disengage no-lift-shift was also not very flexible.

Other issues aside, I think Chris can benefit from this new implementation as well.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Jason on May 17, 2011, 07:54:40 PM
It works!

I can't match-rev downshift though...  It kills the ignition momentarily when I blip the throttle.

I just scorched the earth flat-shifting from 2-3 though :D


edit:  I think an additional set of conditionals is needed so that it doesn't engage no-lift-shift if the brake is applied or throttle position != 100%


Title: Re: Anti-lag launch and no-lift-shift secrets inside

Good idea about the throttle. This would also kill the other issue I have which is bogging the car when driving peacefully or at a stop.

Either throttle over 90% or so OR only when RPMs are higher than some rather high value where you are racing for certain. But I think the throttle would be the ticket.

RPM based sounds easier and better IMO.

Set it above 5000RPM. Bam.

Post by: Jason on May 17, 2011, 09:29:03 PM
Well, let's think about this a bit - would it be wise to have the flat-shift actually function as a rev limiter itself, to improve gear selection as well by starting to slow the engine down?

Not the function, the trigger...

If RPM = > 5000 then no lift shift on
Otherwise off


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Jason on May 17, 2011, 09:48:13 PM
Yep, I get that... 5000 would be too low for me so I'd prefer it to be a scalar obviously. 

Traditionally the systems I've worked with have fueled on schedule (there is a pulse-width parameter you can adjust for anti-lag fueling), but fired the cylinder on the exhaust stroke - this way the exhaust valve is open during combustion and rather than the burning fuel being used to maintain engine speed, it generates tremendous pressure to keep the turbos spooled.  A side effect is that the engine slows to around the expected engagement RPM when everything is dialed in right.

It is really, really hard on turbos when done that way but really really effective.  :)

I think the throttle trigger would be better or even better BOTH RPMs and throttle. It should be fairly easy to set it up that both have to be true to execute no-ignition routine.

This way you can set it up the way you want:

If you like just throttle, set it up to 90% or whatever and "floor" RPM to 0. It will kick in when clutch pressed at 90%+ throttle regardless of RPMs.

If you like just RPMS, set up throttle to 0% and "floor" RPM to 5k or whatever works for you. Whenever above you cailing RPMs and you press the clutch you will get the fireballs.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Jason on May 17, 2011, 10:08:18 PM
Is it possible to cross-fire cylinders? e.g.

1 fires 6
4 fires 2
3 fires 5
6 fires 1
2 fires 4
5 fires 3

If so, that would produce the best result...

edit:  that would work best for anti-lag - not sure how well it would work for launching - it would probably have to alternate correct/incorrect order for launch control...

Well see since I'm not the one that will be doing the coding, I thought of the easiest solution.. I really want to see this ported over to different SW versions first though.

Having both option would be ideal but beggars can't be choosers.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: setzi62 on May 18, 2011, 10:20:07 AM
Here is an update together with XDF, using more conditions to control no-lift-shift:
  - Brake NOT engaged, and
  - Engine rpm higher than a selectable threshold, and
  - Accelerator pedal engaged more than a selectable threshold
Releasing the clutch stops immediately the interruption of ignition.

New pseudo code:
Code:
function_antilag_noliftshift()
{
  // Anti-Lag
  if (B_kuppl && vfil_w < SpeedThreshold && nmot_w > LaunchRPM)
  {
    tsrldyn = 0;                // Interrupt ignition
    return;
  }

  // No-Lift-Shift
  if (B_kuppl)
  {
    if (! B_brems && nmot_w > RPMThreshold && wped > AccPedalThreshold)
    {
      // NoLiftShift is active
      if (counter_NoLiftShift < IgnitionCutDuration)
      {
        tsrldyn = 0;            // Interrupt ignition
        counter_NoLiftShift++;
      }
    }
    else
    {
      // Other conditions not true, don't allow ignition interruption
      // until clutch is released and pressed again
      counter_NoLiftShift = 0xFFFF;
    }
  }
  else
  {
    // Clutch released -> re-arm NLS
    counter_NoLiftShift = 0;
  }
}

Sounds like killing some parts when you see fireballs ... Maybe you need to tune the
IgnitionCutDuration to a reasonable value, in the file are only some default values.

Ok, I patched new code in, set anti-lag to 70% throttle and 5k RPMs flat shifted 2-3 like there is no tomorrow, my clutch floated a bit due to 20psi at red line when I dropped the clutch but it was pretty smooth ride-wise actually. Constant pull no more dip and wait for boost to build up.

Rev matching below thresholds works as to date, no more no lift kicking in... I think it is as good as it can be using current methodology.

Next step is to find how we can retard timing on demand to stupid values and do the thing the right way.

Excellent work.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Jason on May 18, 2011, 02:03:00 PM
As far as safety...  With stock manifolds or poorly welded tubular manifolds... probably not safe.  

It is extremely hard on every component.  Extremely.  In rally cars it's not uncommon for the turbo temp to quickly jump 400-500 degrees C with the system engaged for launch.  Wastegates can be destroyed if the system is effective enough to generate more boost than desired.  EGT sensors will have reduced life.  Turbine wheels will crack over time regardless of exotic alloys derived from moon rocks...  And the rapid heating/cooling of the exhaust is going to leave it more prone to cracking.

But I have personally seen a car maintain 2 bar between shifts... and it is awesome.  Basically if you're a drag racer running 10.01's and need to break into the 9's, or somebody else is paying to fill your go-fast-crackpipe then it's a great thing.

For the rest of us, it's amusing but not practical at all.

Post by: Rick on May 18, 2011, 02:39:12 PM

You do not need any retard for launch!  I am getting 2 bar while stationary!!!

Is there any way to reduce te amount of boost that is produced? I have no desire to shear off anything in my drivetrain but would like to be able to benefit from antilag when I go to the track. It would be great if there was a way to scale it down to say 8-10 PSI.

Also given the severity of antilag, is the general suggestion not to do this if you still have a cat? I'm running piggie pipes but I still have the main cat.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Jason on May 18, 2011, 05:38:12 PM
To be honest, I think the amount of boost is irrelevant as that incident occurred with no boost.

Myself and several others have launched thousands of times with no issues...  But I will say there are a few things to consider:

If you're going to be launching frequently you should make sure you have good low deflection engine, trans, and rear differential mounts.  I would also run a billet differential carrier.  034 makes one for about $300.  If the carrier breaks, you're looking at a new propshaft, new rear drive axles, new carrier, and maybe even the entire differential housing.  $300 is cheap insurance.

If you have a twin plate clutch with unsprung ceramic discs, or an aggressive unsprung clutch consider a clutch delay valve - it will make driving the car easier, and will reduce the shock on the drivetrain by briefly slipping the clutch on launch.

If you're going to launch, prepare to buy spare parts.

Don't launch your daily driver unless you have a spare car and AAA.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: julex on May 18, 2011, 07:04:43 PM
[Good advices....]

[..."consider a clutch delay valve"...]

I will be soon putting fx700 with two unsprung ceramic discs. I know I screwed myself here buying very good condition used clutch for real cheap but it is the harshest engagement they make for "small" twin so maybe not as bad as same Fx850, but still.

Who sells these valves, I believe USP had one or maybe JHM. They are adjustable right?

Or do you think Clutchmasters quoting me for replacement one kevlar/one ceramic discs for 450 makes more sense?


Thanks.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Jason on May 18, 2011, 07:18:52 PM
I have the FX850 with twin solid ceramics... and it is a bitch on the street.  I asked about carbon and couldn't really get a firm answer on how much it would cost.  My only problems with it have been with the crappy slave cylinders I've been buying.

I have been trying to decide what delay valve to install.  While I use the tried and true clutch slip method called "driving" I find that I am still not as consistent as I'd like.  Enter the CDV which will band-aid my poor driving. 

Tilton has one for $165.  Clutchmasters has one for $168:

http://www.summitracing.com/parts/TIL-90-5000

http://www.clutchmasters.com/custom/documents/FCV2000diagram.pdf

I'm not sure that "3" steps of adjustment are enough.  Also since I hate carburetors, anything with a jet I hate transitively.

I am leaning towards the tilton, because it looks like the easiest to install and less likely to leak - buy new clutch hydraulic hose, have hose shop crimp AN fittings on it, drink beer, install, spend 5 hours bleeding, profit.  :D

[...]FX850[...]

Sprung ceramic and solid kevlars are option for FX850, you know that right? I know it involves PITA tranny (or whole thing) removal but might be the best option to replace these.

Regarding your info on low-deflection mounts... you mean like hard poly rear diff mount if better than soft mount?

I would think that more cushioning is desired for hard engaging clutch like two solid ceramics to soften the blow.

Anyway, some info on FX850 (I found it pretty informational on the subject of what config you can get):

Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Jason on May 18, 2011, 08:12:14 PM
Yeah... I am lazy :).  I was one of the first to run this clutch back in January of 09, so my only option was unsprung ceramic at the time.  Since I had exploded an RS4 pressure plate and poked a nice window in my bellhousing I was very adamant about buying the most badass clutch I could find.  This clutch behaves much better than the aggressive clutches that use rs4 or equiv pressure plates.  I would have changed it already but my garage is full of my other junk project cars and there's no real room to work.  My only real beef is the klanky noise at idle, and screeching when engaging.  It doesn't chatter much, if at all.  But it is hard to modulate.

I run my own snub mount, modified Stasis engine mounts, 034 trans mounts, an energy suspension poly mount on my ASP drivetrain stabilizer, and apikol diff mounts.  I would actually prefer less slop in the drivetrain but do not yet have the cajones for solid mounts.  I also run spherical bearings instead of bushings in the suspension, so NVH additions are something I try to avoid.

As far as the soft mounts - you do not want that rear diff moving at all.  I ruined a propshaft because the soft mounts allowed the pinion angle to change enough to damage the CVJ.  Then I had a really terrible vibe around 40mph and had to scrap that propshaft.  I suspect that extreme movement is also what blows up the rear diff as in the pic I posted.

Also, when you install your clutch, pay attention to the flywheel bolts - CM had sent me the wrong length bolts (they were too long and bottomed out in the crank) and stock bolts did not work either.  I ended up using Ford Pinto 2L flywheel bolts - ARP kit 151-2801 (2 kits since they only come with 6 bolts) which can be ordered from Summit.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: julex on May 18, 2011, 09:04:37 PM
I remember your posts about bolts.

My used kit seems to check out. I measured everything I possibly could including bolts lengths (exact as stock when sticking out of FW, keeping old junk parts pays out!),  pressure on plate splines distance to hub in relaxed position, compressed splines (at release point) distance to hub (almost 1/2  difference there so I am sure the clutch is pretty good), wear on surfaces (you can only notice change in color but maybe 1/64 is that wear on any surface) and all the other stuff.

Albeit I think that two solid ceramic surfaces might be brutal on 850, it will be quite a bit less of punishment on 700 since there is a lot less of contact surface there so it will slip more before engagement. And as far and I understand, there discs are designed to slip all the time (within reasonable temps ofc) without much wear.

I sent an email to CM inquiring about just getting one fiber kevlar disc and if they say ~300 I will just get it,  put the sucker against PP and have a piece of my mind.

Oh... and this all is for an allroad btw :)

Absolutely understood. Of course things can always go wrong no matter how careful you are and I'm okay with that. And you've provided some solid advice (julex too) which I appreciate as I'm sure others here do too. The only reason I haven't sold my extra vehicle is because my S4 is a toy and so I plan on it being out of service every now and then. That being said, if it were possible to reduce the boost then I'd feel much safer actually using this because the stress on the system should be drastically reduced. If it were a setting that could be changed (like a variable to define the ignition delay) to alter how much of any single combustion event was used to rotate the motor vs the amount of energy used to spool the turbo I think that would be fantastic. I just don't know if that is plausible to do.

http://www.nefariousmotorsports.com/forum/index.php/topic,151.0.html

It doesn't build boost like this method does and still holds your preset launch RPM.

Update,

car wouldn't start this morning!  No communication from the ECU either, had to put my spare ECU in.

I used WinOLS to patch the code in so checksum should be ok.  Dnly started once last night when testing - should know better than that!

If the changes are outside of WinOLS's checksum ranges, it won't monitor or correct them.

I modified the bin in hex editor and opened/saved in TunerPro with MTX checksum plugin. Works on my car just fine. I suspect something went wrong with the porting of code on your end as otherwise I just can't see how it would not communicate at all.

With no EGT based shutdown or time based shutdown, you will blow stuff up fast.
If you do not have a decat, you will instamelt your cats.
Good flatfoot shift for drag needs to know gearbox ratio, and revmatch for you.

Good job to chris though.
I have written such stuff myself, but for a little bit older Motronic and know how difficult it is to find everything...

I'm a little hesitant to use the anti-lag and no-lift-shift all the time.

Do people have any thoughts on enabling and disabling this feature without reprogramming the car?

I know the addresses of the cruise control button states, so maybe we could hook up something simple to enable and disable it.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Jason on May 19, 2011, 01:20:23 PM
I agree.  I think parts will be broken with this if used a lot.

Something like pushing the button 5 times in less than 3 seconds to enable while the brake is applied and the car declutched?


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: DJGonzo on May 19, 2011, 01:21:27 PM
Anti lag only comes on if you floor it while you have your foot on the clutch pedal and no lift shift only works when you are over x% of throttle. If you are catless you shouldn't be horrified, but if you want to make it work with the cruise control stalk, be my guest  ;D


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Rick on May 19, 2011, 02:06:36 PM
Found my problem - it was just a bad checksum, WinOLS found it straight away, think I know why it wasn't picked up the first time.

EGT's - for launch they at least they are not high, under 500C.

This is essentially a spark cut rev limiter that you will not be on for a long period of time, no different to how lots of turbo cars run.  Retarded timing and jacked throttle on overrun is different.

Rick. 


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: julex on May 19, 2011, 04:45:45 PM
What you need to keep in mind is that it only cuts the spark while fueling when you're above certain RPMs and/or certain throttle %.

I set mine to over 80% throttle and 5k rpms. Also set it up for short duration, in my experience around 600ms is best.

If you don't keep your foot planted to the floor on the gas pedal while shifting in the activation zone IT WON'T do squat. With throttle closing almost to nothing when you let the pedal go and low g/s the amount of extra fuel will be completely benign.

You really need to drive the car to see it in action and learn when this kicks in. To get anywhere near usable amount of boost you need to essentially floor the gas pedal while rowing.

If you want less, just release the gas pedal slightly and it will take it a bit easier.

It would be nice to have a control over the activation without flashing though. I agree, but it is not a deal breaker to not have it.

A switch isn't needed for the launch/flat shift.

As said above, launch only works if you floor the throttle with clutch pressed and you are stationatry - you never do that in notmal driving.

Flat shift is the same - if you come off the throttle as normal during gear cahnges then nothing happens.  Nobody would know these features are enabled unless you told them.

However...

It would be nice if the code could be adapted to give true ALS.  This *does* kill turbos and would need to be enabled with a switch.  What we need is that when driver comws off throttl pedal, the plate remains open (the more, the more agressive the ALS) and the igntion is retarded massively and/or spark is cut to stop rpm going up.

A lot of the code is there for this from what I can see.  We "just" need to be able to force the throttle open.  Perhaps the request torque variable in RAM could be overitten tempororarily?  Or pedal position?

Rick

Post by: Jason on May 22, 2011, 09:37:29 AM
Is there any way to reduce te amount of boost that is produced? I have no desire to shear off anything in my drivetrain but would like to be able to benefit from antilag when I go to the track. It would be great if there was a way to scale it down to say 8-10 PSI.

Also given the severity of antilag, is the general suggestion not to do this if you still have a cat? I'm running piggie pipes but I still have the main cat.

I posted this in my tuned file thread, but decreasing the launch RPM to 3500rpm dropped my launch boost to 15PSI.  I was seeing 30+ at 4500rpm.  15psi @ 3500 was still frying the tires though.

Ok lets see if someone can figure this one out... When I run this code and the ignition cuts kicks in, my ECU fuse burns. Its not the clutch pedal cuz I can play with it with the car running and nothing happens but if I trigger the anti lag, fuse burns.

hey Jason - i like the lowering of the rpm, but if i recall from the launch-code development, this means that you can't keep the car above 3500rpm for more than 999 seconds?  i can't remember the exact amount, but could you please confirm this is correct?  if this is correct it means your long-term highway speed is limited to 92.5 mph.  now that isn't exactly a problem for most people, but i wanted to confirm this with you...

I know the addresses of the cruise control button states, so maybe we could hook up something simple to enable and disable it.

Tony I used this function daily on a stock turbo K03 1.8T running E85. It shot 6ft purple flames. The damage it did was it melted a flex in the 3" DP and melted a resonator. Expect it to do the same to a catalytic.

I used a N2MB WOT box which I am guessing does the same thing via hardware that the Tapp function does. I got rid of the Maestro curse before this was released. This required a misfire counter disable. I had no other issues with it ever.


Otherwise my turbine was fine, and exhaust valves were fine as well. That turbo is still kicking on a local car being abused with shaft speeds beyond spec.


This and anything else is a nice return for the poorly written maestro flasher and suite which set my car on fire in Indiana during a winter storm.


It was cool to be an unknowing beta tester on everything from your poorly written wizard apps that calculated the wrong values, to the dual bank rom and maestro setup which set my car on fire 1000 miles from home and caused me to have permanent scarring on my hands. Then the hours of time and many dollars having warped hardware machined flat.


Cheers Nefmoto, I'm getting acclimated and plan to contribute how and where I can.

I got the run around from Tapp, but Maestro cooked my timing table, and I guess it defaulted to a static value that was "safe". However with a 3071R @ 22psi on wastegatespring it was not safe, it caused enough EGT to set the firewall insulation on fire under the blanket. I scraped it off by hand at a gas station in Indiana then the ECU settings adjuster would not work right. I had to lemmiwinks a static timing advance to counteract the static retard.

All of this during a snowstorm. I was driving like a grandma. Had I been beating on the car not sure it would have been a recoverable fire/failure.


Best part? The flash reported "Flash completed ok/successfully"

Then I got "Why did you flash your car 1000 miles from home?"

Gee because your software should work right since I dropped a grand on it. The accelerator pedal map in that tune sucked horribly. The maps looked like 2d rollercoasters. I was not happy after giving it many chances, and updating the "suite" at least 10 times.

BTW, fire was post anti-lag/NLS box. It was 100% the fault of Maestro.

Lots of arguing/shipping ECU to canada. In the end I was out a lot of money, melty hands for a while, and time having all the exhaust hardware redone and putting a new head on after Maestro's timing mishaps made my exhaust valves the color of cigarette ash.

I was bribed with a refund to shut up, but hey people need to know the kind of person they do business with and trust.

I really need to dig into this, but still without the suitable ME7/Audi or at least Windows Vista ;)

regarding NLS, how far is your effort gone with replacing spark cut with retard?
How dangerous do you consider using NLS only?

regarding rev matching: aren't revs likely above the syncing rev of the next higher gear if you shift normally fast in a non-race car?

Run into a slight issue.  When flat shifting, ECU is picking up a lot of knock from the missfire.  It's pulling out 12 degrees due to this, which then takes a few seconds to then advance.

Shift faster?  :D

I haven't noticed this to be an issue.  Wonder if there is a "knock control timing advance" variable in ram that can be decremented to force the knock control to restore full timing right away.

Do you log knock directly or by seeing ignition moving to late angels?


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Rick on May 31, 2011, 04:48:55 AM
I can see the correction factors shoot up as soon as the ignition cut happens, and the ignition angle drops. 

I've now set the duration back to 200ms from 600ms.  Much better like this, still shifts as well but only get 6-7 degrees retard.

It's still too much though.  You can see as the rpm increases it gradually recovers as knock is no longer detected.  I will force it to recover more quickly and see how that goes, but it's not ideal.  What we really need is for knock control to be disabled when clutch switch is acticated - one for Setzi?

Jason, have you actually taken logs of you flat shifting through to 5th gear flat out?

I had to have my misfire counter disabled in order to run this.

You can still log the channels and watch the counters increment with it disabled, however it is done by Eurodyne. they just reset fast before an overflow, which triggers the retard I am guessing.

A temp misfire disable would be slick.

Just re-enable it when you need to log misfires for any reason and turn the functionality off.

Post by: julex on May 31, 2011, 04:22:51 PM
I made several shifts 2-3rd with full throttle NLS and I noticed -12 retard in one instance. There was no abnormal activity from knock sensors so it muis be misfire detection kicking in or something.

I had no time to dive into more assembly on ME 7.1 so I cannot contribute anything constructive to this "issue".

One thing I will say is that I would be hesitant to disable or "reduce" any of the knock control effectiveness, as increasing loads in the new gear has always been an area where my car likes to ping.

If you guys are having misfire detection kicking in you should look at DMDSTP folder on any damos. You should see some maps where you can disable it at x conditions.

Use Google translator  :P

There is various things you could do. You can disable knock detection by load threshold or RPM threshold. Its is very simple depending how you want to do it. RPM threshold is the easiest and more sensible solution IMO.

I've cleaned up this thread. Please stay on topic, because this thread should be a valuable resource and not go off on a tangent. If you want to discuss a different topic, please start a new thread. I prefer to spend my time writing ECU software and not moderating the forum.

The summary of my moderation:
  • Gonzo removed his posts, and created a new account
  • Gonzo now offers anti-lag and no-lift-shift in his tunes

Please try to give more to the forum than you take, and that is all I ask.

Well getting back on topic...

Yesterday I did some NLS testing... and I found that if you never lift on the throttle my AFR's bottom out shortly after going into the gear... I have a log file of this happening and I will post it soon....

Anyone else ever notice this behavior?

component protection due to high EGT?

It is very possible... I did just do one 3rd gear pull/log and then right after a 2-6 gear log... and only gave it maybe 5-6 min before doing a full out ALS launch with a 2-3 NLS (which is where it happened).

Yes I put my car through it's paces yesterday :P

Full log is attached... have at it!

I think that EGT falls, it doesn't burn until it hits the atmosphere. Log egts, if you have rs6 sensors which read from below freezing.

AFR goes crazy to to oxygen in the exhaust stream

EGT goes up Spen, pretty quickly.  I have an additional sensor.

Correct... EGT's skyrocket w/ ALS and NLS.  Which is why many aftermarket/standalone ECU's have a safety that take into account EGT temps and shut down these options if they get too high.

Correct on rising EGT.  I am guessing moments after activation the design limits of the compressor and manifolds is achieved and surpassed.

I've only watched one car EGT wise, and it's EGT actually went down during launch control.  I didn't ever see what it did on no lift shift.

As I said, only one car though which is not statistically significant.  How many cars have you examined and EGTs have risen?

Pretty much any car I've tuned a stand alone on... ALS works by making the combustion in the manifold/exhaust (highly retarded timing + extra fuel).

Post by: spen on July 19, 2011, 10:06:54 AM

can only report what I've seen when adjusting tsrldyn to zero; egt fell on one car.  I don't have an additional sensor, I use rs6 sensors calibrated down to below freezing in the ecu. Both banks fell from 900 degrees Celsius starting point.

What was your EGT before you used ALS / NLS?



Title: Re: Anti-lag launch and no-lift-shift secrets inside

Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: spen on July 20, 2011, 12:12:58 AM
When you say certain cars, do you mean with this mod?

This mod hits a variable called Tsrldyn which is used to generate a coil dwell. The dwell time is used to charge the coil. Without the charge time it can't fire.

So you should be pumping fresh charge unburnt in to the manifold which then pops and burns either behind the car or late in the exhaust pipes.

All commercial ALS i have seen ignite the charge on the exhaust stroke, sending burning gas in to the manifold giving immense EGTs.





Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Jason on July 25, 2011, 10:35:30 PM
On WOTBOX cars specifically, yes.  I believe it functions the same way by cutting spark by eliminating the coil charge.  Since the throttle is open, air and fuel hit the hot manifolds and light off. 

I could probably test this using a laser pyrometer once it cools off here.

was wondering if maybe someone could throw me a bone here.
im no coder nor do i pretend to be a coder. and ida is still mostly above my head.
however, im trying to patch this routine in to my file but im not really sure what im looking for.

on the 2nd page someone mentions that the dwell ram location is easy to find because its in the routine that gets jumped out of. so i was wondering if someone could help me locate that and then i would at least have a starting point?

also, this is a really dumb question, but how do i add asm code in ida? i can do edit (f2) and edit hex but i know there has to be a better/easier way to patch the code.

any sort of information is greatly appreciated.

heres my routine. i already made a hex edit to jump to ffa60 (is it right?) :

There is a patch program menu under edit, but I don't think there is any real word use for it. I don't think you will be able to assemble your final product. Ida can create executables in certain instances, but the disassembly has to be perfect.

Unforunately that is the extent of the help I can provide. Have you read the sticky on this topic?


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: k0mpresd on August 26, 2011, 04:39:09 PM
is dwell ram address 8ba4? bueller?

ok, so looking at that pseudo code, in the original added function for the m box, 8e40 is vehicle speed ram address and f87a is engine speed ram address. is that correct?

^^ pretty sure thats correct. so how would i identify these variables in my file? ive tried following the code backwards in the mbox file in ida to try to figure out how they are id'ed but not so much luck.

could someone explain where the f87a comes from? i dont see it referenced anywhere else in the code except in the custom routine. 8e40 is referenced in the custom routine and ida also lists data xref: rom: 0x8695da.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: k0mpresd on August 27, 2011, 09:41:59 AM
so is 9c40 one of the variables im looking for? this routine matches verbatim (almost, just locations are different) to the s4 routine where the 8e40 variable is pulled from (im still assuming the 8e40 and f87a are the variables you need to find).

s4:

ROM:8695DA                 mov     [r0], 8E40h ; 8E40h
ROM:8695DE                 mov     r4, [r0]

k0mpresd, do you have Hex-Rays?  It's a simple plugin that will render some C code equivalent to the disassembly you're looking at.  Not sure if it will work for these binaries but it works for x86 binaries so it's worth a shot.

Looking at C code instead of ASM will undoubtedly make your life much, much easier.

Any progress on the 1.8T porting?

Any more info on the blown coils caused by these mods?
There is no "1.8T" port working for all 1.8T cars. Added code runs only on the
specific box it was made for. If you want to get some custom added code running
on another image, you have to find out several addresses of internal variables.
These addresses vary with each image. Then assemble the code again,
using the updated variable addresses and link it into the existing code.
So for every new image, the work starts again. No copy-and-paste of
custom code is possible  ;).

Regarding the blown coils: the "hack" of setting the closing time to zero is
not working with older version of the ignition driver software in the ecu.
The sw driver doesn't handle this correctly and produces "illegal" ignition pulses,
leading to high current in the ignition system. If you have an ecu with old
ignition driver software, you have to implement the interruption of ignition
in a different way, otherwise you will risk your coils (or just blow a fuse if you are lucky).

This code is a 'hack'. There is a proper way (or at least a "more" proper way) to interrupt the ignition.
Just a tip... Maybe someone will pick up on this tip  :)

Why bother cutting/interrupting ignition at all? It is not the correct way of doing anything to a running engine.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Jason on December 04, 2011, 02:03:07 PM
Because functionally it serves its desired purpose of building boost and maintaining a set launch RPM.

I agree that it would be more desirable to retard the ignition timing until the air mixture is leaving the cylinder - but this "hack" works without much work and achieves the desired result.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Gonzo on December 05, 2011, 12:05:00 PM
Yeap. Its the easiest way to do it. I tried retarding ignition and it didn't work.

Post by: setzi62 on December 06, 2011, 05:32:00 AM
Wether done by ignition cut or by ignition angle, antilag in ME7 seems to be always a "hack"  ;).

Regarding the ignition angle:
in all ME7 files that I have looked at, the system constants limiting the
ignition angle in the ignition driver code are set to:
  SY_WMIN  = 0xE0 = -24.0 deg
  SY_WMAX = 0x4E =  58.5 deg
I would guess, these are limits of the driver implementation on the C167 and if you
just circumvent these limits, the driver probably might not work as intended.

So, would -24.0 degrees be late enough to keep the engine from raising rpm?

matchew: did you implement successfully antilag using ignition angle modification?
Is the driver code able to produce ignition pulses later than SY_WMIN?


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Jason on December 06, 2011, 09:05:39 AM
I don't think that's enough.  Most systems are well over 30 degrees.

Aha! -24 deg makes the RPM's drop for sure but it makes no boost.

matchew: did you implement successfully antilag using ignition angle modification?
Is the driver code able to produce ignition pulses later than SY_WMIN?

Yes I have done this and experimented with different angles and strategies. Of all the methods I have written this is by far the best way although one of the most complex.  It is how ever the correct way along with sequentially cutting cylinders.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: setzi62 on December 10, 2011, 02:25:04 PM
That sounds good. Is cutting cylinders needed to limit the produced boost?
And I guess the limitation (SY_WMIN) to -24.0 deg has to be removed or was
this ignition angle sufficient?

24ATDC is not enough to prevent RPM climbing. I have gone much further than 24 degrees. This creates MASSIVE heat in the exhaust system. At one point during testing on a NA engine, I measured the exhaust gas temperature at well over 900C with in less than half a second of the engine reaching the RPM set point.

Ok, this stuff is way beyond me. lol

Was thinking, if you can only get 24* on the output side, could you manipulate the input side to get the rest? Is there a crank trigger offset that you could make the balance up on? Have a feeling it would freak out the cam sensors and drag both fuel and spark with it though. Just an idea.

I've been testing out the AL and NLS code on a friends car and I have a quick question.  Not sure if it has been mentioned on here before or not but if the NLS is used, it will work fine 1st to 2nd and 2nd to 3rd but when the clutch is reengaged in the 3rd gear the car is in some sort of limp mode and builds much less boost then it should be (would be without using the NLS function).

Has anyone else seen this?  Any particular things that I should be looking at to correct this?

Thanks!

^^^ Do you have an AFR gauge in that car?

I have the issue that the car goes full rich when I do a 2-3 and 3-4 shift with NLS... and only recovers if you let off and get back on the gas.

don't we need to distinguish between launch and NLS function?
I think during WOT shift in 0,1 or 0,2 sec. some short raise of EGT is ok and boost is not dropping too much?!

No, it's a genuine.  Bought it like 12 years ago.  I'm going to try to see if they honor the "lifetime warranty".

I will probably end up machining my own as it doesn't look like there are any other shifters out there worth a damn.

Yes, in the drag run video with my girl friend in the car that I have posted that is exactly what happened.  I have it in logs too.  It only does it if you do a full out run, ie every gear or als then nls back to back.

I tend to skip gears now for best results as I haven't had time to investigate.  It massively regards timing and dumps fuel.

Post by: corradovolksb on April 13, 2012, 04:25:23 PM
I am having the same issue also. when I use nls from 2nd-3rd I can hear the engine pinging durring NLS and then my boost stays at 10psi and will not go over that until I let off or shift into 4th normaly. I dont have a AFR gauge so im not sure what my fuel is doing but if I had to guess some sort of failsafe is activating causing the boost cut.

Update,

car wouldn't start this morning!  No communication from the ECU either, had to put my spare ECU in.

I used WinOLS to patch the code in so checksum should be ok.  Dnly started once last night when testing - should know better than that!

Found my problem - it was just a bad checksum, WinOLS found it straight away, think I know why it wasn't picked up the first time.

EGT's - for launch they at least they are not high, under 500C.

This is essentially a spark cut rev limiter that you will not be on for a long period of time, no different to how lots of turbo cars run.  Retarded timing and jacked throttle on overrun is different.

I'm seeing something similar to this.

Car wouldn't start. I cleared DTCs (misfire) and the car fired right up. I'm assuming that isn't a checksum problem?

although it could be misfire diagnosis DTC from doing too much AL on a motor that isn't at 80C yet... a ton of unburnt (and non-vaporized) fuel everywhere, I assume.

is there an ECU shutdown on too many misfires? I saw another post about AL/NLS causing misfire DTCs:

I had to have my misfire counter disabled in order to run this.

You can still log the channels and watch the counters increment with it disabled, however it is done by Eurodyne. they just reset fast before an overflow, which triggers the retard I am guessing.

A temp misfire disable would be slick.

Just re-enable it when you need to log misfires for any reason and turn the functionality off.

In any case, i have a request for setzi (or anybody else..) is there a way to disable this if engine temp is below 80C?

And a way to disable misfire detection while AL/NLS is active?

And this

We need to disable knock detection when the ignition cut kicks in.

That's one dirty car you have, Jason  :P

Lol, I know...  It's a track whore that happens to get street duty now and then when the weather is nice.  Oh, and I use it to haul lumber, bags of concrete and dirt occasionally.  I've had 12 80lb bags of concrete in it before.  It hooked up in first gear ;D



Looks like JHM wouldn't break in half like that....

That's what I ended up buying in the essence of time.  We'll see how it holds up.  I've missed third a few times with it, whereas the last shifter didn't like second.  I just need some practice I think.


As far as the ALNLS, I really haven't had any issues with knock control.  What are you guys running settings wise?  I've got at least 5,000 miles and 100 or so launches without any issues you are describing.  The only thing I've changed is the ignition cut duration to 1500ms.

I also have my EGT's disabled.

I was thinking one possibility of preventing the use of LS while engine temps are cold would be to set the soft limiter below the LS RPM until engine temps are >79C

Boost stays at ~0.8bar during shifts. On video spark cut is set at 160ms, now i use 120ms i think 100ms would be best.

Post by: prj on July 02, 2012, 09:35:39 AM
Started looking at this...

Code:
// No-Lift-Shift
  if (B_kuppl)
  {
    if (! B_brems && nmot_w > RPMThreshold && wped > AccPedalThreshold)
    {
      // NoLiftShift is active
      if (counter_NoLiftShift < IgnitionCutDuration)
      {
        tsrldyn = 0;            // Interrupt ignition
        counter_NoLiftShift++;
      }
    }
    else
    {
      // Other conditions not true, don't allow ignition interruption
      // until clutch is released and pressed again
      counter_NoLiftShift = 0xFFFF;
    }
  }
  else
  {
    // Clutch released -> re-arm NLS
    counter_NoLiftShift = 0;
  }
}

One thing I don't get - why disable ignition cut completely if RPM falls below threshold until the clutch is depressed again?
In fact, I don't see the entire logic between locking out the ignition cut at all.

Before it cuts ignition, it checks if all the conditions are met. If any of them are not met, it should IMO just reset the counter and that's it. At least that's how I did it on the older ECU's.
Am I missing something obvious here?

regarding NLS only:
Ì miss some efforts about cutting fuel instead or additional to spark cuts/retards.

the conditions during NLS should allow cutting fuel for 100-200ms without losing too much boost.
or did I miss somthing?

I'm going to throw you a bone here.
Download the file 1.8T k0mpressd posted up with ALS/NLS and then download the ori. Figure out the changes.
There is a jump and some added code. Disassemble it. Now figure out what each RAM address is and find it on the new (target) file.
Open Keil compiler, paste code, correct ram addresses. Now compile and open file. Find code, paste to target file and add in the jump to your code.

You also need to have the right bytes.

Maybe I should do a tutorial.

its somewhat sloppy, scribbled from my notes on how i manipulated setzis routine to work on my ecu, in about 3 days.. and it is just that, code manipulation of allready compiled code, but still, it works 100% on all ecus with the compatible coildriver.
(and no, ive never used acrobat to make documents before..!)  ;D

id love to learn more about that kiel compiler.. i went down that road first, but i never got it to work.. at all.. =S
then i think it was Tony who adviced me to try and manually change/manipulate the allready compiled code instead, as an easier alternative.. and yeah, even that required many hours and IDA pro dissassembling back and forth.. but in the end i got my own code to decompile into the same as setzis.. and figured out a pattern.. :)

i tried a smaller command-line 166/167 compiler that seemd to work, but it took ONE row at a time.. and forever to make even one function operational.

would be nice to even start a thread about compiling with the kiel, the first steps to get it running.. which we later on can expand into a tutorial.
i have a few ideas, notes on functions, that i would love write, compile and throw in there..  ;)

If you are writing subroutines into code, then better write in asm right away, as it will be very hard to set up a C compiler to do what you want and you will end up writing things in ASM anyway.

It was cold this morning (85 degrees) so I decided to give her some stick on the new engine. 

It falls on its face after every no lift shift now...  Unfortunately I wasn't logging.  I'll try to get back out in a bit to reproduce it with logs.

A quick glance at my wideband showed it was in 9:1 territory when it was on its face.

So I setup the datalogger this morning, went out, and it worked every time.  I must have tried 20 times to replicate the issue.

Only difference between today and yesterday is it's about 79 degrees now.

The only thing I didn't test was shifting more slowly...  Part of me wonders if I was slower yesterday because I haven't done it in a while, and the more time you spend with the NLS engaged, the greater the chances are of knock regulation kicking in.

Post by: sn00k on September 17, 2012, 03:56:37 AM
correct me if im wrong, but.. IF the VSS-sensor gets disconnected, for anything to happen, you will still be running 95%+ throttle, at an rpm above the set launch-rpm and simutaneously pressing the clutch.. which basically means your doing a WOT-shift.. so it will go into NLS mode, and not much interesting would happen there..? ;D

Wrong. Without the VSS, it will think you are stopped, so everytime you hit the clutch pedal, it will trigger anti-lag at the preset launch speed.

The funny thing is that the code I currently use doesn't use TPS for antilag, just for no lift shift and for launch speed adjustment.
E.g. If you are not completely stopped and have your foot on the gas all the way down, you cannot adjust the launch speed. I would post a video but I don't wanna brag  :P

right had this enabled for while now still loving it but with NLS shift noticed a bit of a problem every now and again when change up a gear via NLS seem to lose power and boost drops down between .2 to .4 bar (random), simply lift off the throttle then back on brings back full boost/power, now obviously had computer on nothing comes up fault code wise (not logged anything as of yet) but feels as if lambda adjusting fueling maybe???
anyone had this or cure ?

Personally I only think it happens when you shift too slow.  What the acceptable duration is, I don't know.

ive noticed this too.. shifting from 1-2 and 2-3 seem to work fine, but 3-4 and it shifts like butter, BUT after about 2 seconds the boost drops and AFR is spooky... im rewriting the code to fix this, ill post the updated code here when i have solved it =)

Tried few different technics first trying very hard fast shifting then settled for less aggressive change which I found better for me and feel of the car/power


Glad not just my car getting this issue can't wait now for code now ,makes car I think so much quicker though the gears, like to time before/ after on 1/4 mile run

0002E : 8A 2B 22 60       JB       2BH.6,0076H ; =0x00FD56.0x0040
Is it b_brems? I have not found it in *.ecu file for the M-box.

Post by: automan001 on October 18, 2012, 12:43:13 AM
Sounds like killing some parts when you see fireballs ... Maybe you need to tune the
IgnitionCutDuration to a reasonable value, in the file are only some default values.
When I analysed NLS code line by line comparing values with the dump 8D0907551M_AlNls_v2.zip I found following in NoLiftShift part of function:
AccPedalThreshold is defined in .bin with value E6 FF which won't work if map defined as byte and you leave it default or will try to change the byte. There should be word.
I guess it was supposed to be E6 00 = 230 * 0.392157 = 90 grad
The part of code which compares threshold reads word from 017E08H address:
0004A : C2 F9 08 7E       MOVBZ    R9,7E08H   ;AccPedalThreshold, 81H:7E08H (017E08H in bin), value = E6 FF???
0004E : 40 49             CMP      R4,R9
Therefore IMHO there should be word E6 00 and AccPedalThreshold map should be defined as word.

P.S: already sorted out, MOVBZ: Moves and zero extends the contents of the source byte specified
by op2 to the word location specified by the destination operand
op1. The contents of the moved data is examined, and the
condition codes are updated accordingly.

So this approach works fine on one of my cars.  On the 02 A4 1.8t though it is destroying ignition coils rapidly.  There was some talk on here about the dwell going to zero causing illegal ignition signals on some ECU's.  Has anyone found out more about this or a way around it? 

I was considering setting the min to the lowest possible time greater than zero.  I'm assuming the error is caused by zero as an input to the dwell time?  but I've trashed 3 sets of coils already and if anyone knows that zero as the time is the issue that would really help.

You need code that doesn't change dwell time...

0 dwell time is what makes the coils explode.

All four of my coils did this, but I was not using NLS/LC any time close to when they went out. The problem might have started after testing LC a few times, but when they actually died it was just misfiring. I had to keep driving as I was going to school, and it kept getting worse. When I pulled over and took the coils out, they were all very very hot.

Has someone come up with code that does not manipulate ignition dwell? I would like to know if there is.

Gents, is this code not already present in some form or another in the tiptronic engine binaries? Certainly looking at the traces from my car, ignition timing is retarded to TDC on shifts to cut torque while maintaining boost pressure. Throttle plate angle isn't touched at all really.

yes. All it needs to activate the NLS is the % of the accelerator pedal to make sure its over the threshold set point. Wped_w will achieve this.

I'm not familiar with this routine or the context that wped is being used, but 8 bit and 16 bit variables are handeled differently. If the code is written for 8 bit wped the wped_w will not work.

No, this is just fast path torque intervention.

The Bosch ms-4 utilizes a gear cut and blip system for shifting. Just skimming through it, it says that engine torque is cut using the ignition angle map. Since the Motorsports ECU and the me7 ECU are very similar, you don't think this should be looked into?

Pg 62 in the ms-4 data sheets btw.

I compared many files and noticed that wped is always 2 bytes after DWPED.
Example:
0x380ABC dwped
0x380ABE wped

This mod hits a variable called Tsrldyn which is used to generate a coil dwell. The dwell time is used to charge the coil. Without the charge time it can't fire.
Are you sure ?

Could the burnt fuses in some cars mean that tsrldyn=0  actually powers the coils permanently ? 
It will actually work too, as a coil only sparks after you remove the power to its primary winding.

Maybe someone can find a better way to interrupt spark.

Yes, in some ECUs tsrldyn -> 0 is bad news. I think there was talk a few pages back of finding writing an alternate routine, but I'm not sure anything came of it.

Has anybody made any progress on the correct way to do this?

I'm convinced we're having issues with the knock control intervening on flat gearchange because the engine IS knocking.

Back when this was first implemented I had a slight idle misfire which was due to a broken plug insulator.  I didn't really think much of it at the time.

Fast forward to now - I put the quiet exhaust back on my car to diagnose a drivetrain noise, and can definitely hear it knocking when the NLS is active between gear changes.  There is no question in my mind it's knock.  I think the issue is the coils are discharging randomly and knocking the motor.  I am going to see if I can put a microphone under the hood to capture it.  It is audible, and it is knock.

I know MRC appears to have this working perfectly, so I'm curious to know how they are doing it.

Post by: phila_dot on April 06, 2013, 07:18:09 AM
It's really just a matter of someone sitting down and actually doing it.

I think a fresh thread hashing out the conditions, features, and functionality would be a step in the right direction.

It's on my list, but not a high priority. Anyway, my computer's down and my car needs attention, so I'm regretfully not making progress on anything ATM.

I cooked my MAP sensor this morning trying to launch.  About 2 seconds in the engine nearly died and wouldn't idle on its own.

MAP sensor implausibility and signal too low DTC's.  I was worried I smoked the ECU, so I swapped the spare ECU in and no change.  Swapped the sensor and it was fixed.  Not what I expected, but cheaper than roasting an ECU.   ;D

I ordered a 4 bar sensor to try as well.  How much boost are you seeing when it's active?  Mine fluctuates around 30 or so.  I'd have figured if there was some massive pressure spike I'd have blown a hose off somewhere.

If it's cutting ignition where you want it to but going through that wouldn't be due to not enough cut/retard that would be because the 2nd rev limiter isn't work IMO

can you provide a me7logger csv during shifting?
cutting (=no) ingnition would mean zero or negative torque which means no revving up.
you probably retarded it which left too much torque.

This isn't a rev limiter - it's a timed ignition interrupt that becomes activeABOVE the desired RPM.  Back towards the beginning of the post the operation is discussed...  Maybe you can try using the NMAX "launch control" in combination and set the launch speed 500rpm higher than the antilag activation.  See here for more info:

I don't have at all neither knocking nor timing retard at block 020!
It is weired!

cracking spark plugs = detonation

Right... and with no change to the tune, just disabling ALNLS, the problem stopped.

I logged Timing Retard during NLS now, i noticed in one car i have always ignition retard during nls and in other car i havent.
Same ECU (032HN), in one engine i got very strong engine bearings (without knock) and in other i think the downpipe or some part of exhaust is hitting something during fast shifting.
If i Shift slower i have no ignition retards, also im 100% sure its something hitting the engine or exhaust parts.
Maybe thats your problem too?

Use better spark plugs.. but really, if you cut spark there is nothing to cause knock.
There can of course always be pre-ignition, but pre-ignition is silent, and at least on gasoline it is very hard to produce.

ive too noticed high CFs, and im 110% cirtain i can hear pinging at most NLS shifts.

gasoline is very resistent to preignition per se, iirc ~280degC or so, but perhaps this phenomenon is caused by the combustible gas-mixture that passes right thru the cylinders and into the hot exhaust gasses/valves/turbine, ignites there and backfires into the cylinders when the valves are open.. just a thought.

leaning out/enriching/cutting fuel at the same time as the spark should prevent this..
 
i understand this detonating in the exhaust manifold is a somewhat desirable effect for the big-turbo users, used to minimize lag when shifting, since it gives a huge boost to the exhaust gasses, temps and turbine to keep the turbo spooled.

perhaps cutting fuel alone would prove a softer and better NLS for stage 1-3 tunes..?

I have very stiff motor mounts and trans mounts. So I doubt the motor is moving around very much.

Jason, how many NLS did you need to do till you noticed cracked spark plugs. I have only used NLS 4 or 5 times due to all the timing that gets pulled.

I'm not really sure, I used to use it all the time until I started blowing up map sensors.  I'm 95% certain it's pinging.  You can hear it...

Here's a video where you can hear it pinging.  While yes, you're cutting spark, it's not to say there isn't an abnormal combustion event.  Take a close listen and tell me it's not pinging:

Think there's something wrong with the 032HN one I'm using, too.  I ruined a set of plugs, and coils.

And it's working when I'm moving, too.  And bangs everytime I shift over the AL RPM..

This is how the quickshifter on my bike operates, and that routinely sees 18,000RPM WOT shifts. My fuel cut duration is 500ms, haven't crunched a gear yet.

I'm not getting any knock during my launch, only while I shift with NLS.

Do you can do a test for me?
Set NKRF or TMKR or any value you never reach.
change your ignition to very very safe angle.
Test the NLS Function and Log ignition retard and knock.
If the ecu is stops to retard ignition ill do update to code.
I have no Engine that is retarding ignition while shifting, also i cant test it at the moment.

FYI for anyone wishing to use the NLS and Launch Control the address for the 001 M-Box version, the location for the JumpToALNLS in code is not the same as the 002.
Use 0x8B39C for the JumptoALNLS for 001 M-Box

This is my first attempt at a gasoline engine, tried also to patch the AL&NLS routine. Included is OLS file, ecu definition from me7logger and manual notes for the patching procedure. Doing this to make a gift to a close friend.

Please someone review it, and tell me if i patched routine correctly.

[offtopic]My ever first gasoline tune is in the OLS too, any advice will be welcomed on PM not to be offtopic here ;) [/offtopic]

If you have a running car (s4 preferably) and want to test, email me your file.

ddillenger84@gmail.com

That'll get you the current code (that is pretty much done, complete with customizable retard for launch). Only thing I ask is LOGS of antilag and NLS.

It'd be preferred if someone that had timing pull during NLS does the testing.

If it throws a rod, so shit..

Only problem I seem to have is on the original code (with FTOMN), my coils lasted 5 seconds.  Sure I read somewhere that for some reason my HJ ECU has the older coil drivers, and can't support FTOMN being 0.

Either that, or it's an HN and it can't support, I forget.

More than happy to test though! :)

Awesomesauce!

Do you know what's changed?  Hoping to get the current version off my file (as I applied the patch before I started messing with it), so need time to remove it, and then get this one changed.

How does it work - ie, what's changed so that it doesn't take the coils out like before when I had FTOMN at 0?


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Snow Trooper on April 05, 2014, 11:06:30 AM
Start with a clean file, dont remove the current patch.

Whats changed is that it operates like a real ALS/NLS function.  The old setup that is widely used is more of a hack.  This one gives control over actual degrees of retard, where the function kicks in and where it lands RPM wise, it also disables knock and misfire control while using the function.  My car has never been this fast in regards to a drag type run.  It is brutal.

LOL yeah... still putting it back together between paying jobs...

For those curious, I had a bit of a mishap with some very aggressive settings on this new code, I overlooked the fact that my cam settings allowed advance/overlap during ALS and well, the intake manifold doesnt handle explosive energy as well as the exhaust manifolds and turbo does.  So after sending the booms the wrong direction through my engine I can say with confidence you dont want that to happen.

not for lunch but for NLS .
when I tested the common function on a freinds RS4 it boost a lot (2.1 bar peak boost stored in gauge)
i dont mean cut the function but skip the function until boost come down then restart the function like a condition for the function to be enabled .
PID con't handle this .
and open loop for wideband ECU is because wideband sensor is pretty responsive when hot and can lean the mixture just because unburnt fuel go to the exhaust .

This is a very uninformed statement. When the mixture doesn't burn it would go RICH. Raw fuel isn't detected by the o2 sensor, just the oxygen! It would read lean if anything.

the car overboost 2.1 BAR on shifts . it's too mutch for k04 .
i don't want to kill boost but prevant turbo from overboosting 

some fuel must burn in the exhaust manifold, I can't predict what it will read but i thaught it was a good idea to desable closed loop and have a perfect control of lambda .

I think boost control during launch would be ideal. You could set rpm and fine tune with boost or vice versa. If both were selectable on the fly, that would just be sick.. :o

Post by: phila_dot on April 10, 2014, 05:28:42 PM
It seems that everyone is missing the main priority which is controlling engine speed.

You can't just disable the function if boost pressure passes a setpoint because then engine speed will quickly shoot past it's setpoint. Simpy disabling the function will not work as whichever condition you put first will almost always stay in control.

If the boost pressure is too high during launch or NLS, then you must adjust the ignition angle or ignition cut duration (depending on method), but you still need to remain beyond the point of accelerating engine speed. IMO there really isn't a good way to set this on the fly and I don't think that a dynamic solution is a very good idea.

missed that point, you're right .
but launch control don't react like NLS .
so different setting of ignition retard or cut must be applied .

I get it with the NLS but shouldn't torque be the limiting factor for launch control, or wheel spin, not necessarily engine speed, after all it is "excessive" torque that produces wheel spin. I think if someone could hack our ABS/ASR and have wheelspin detected during launch (I'm guessing the signal would have to go through CAN) the end result would be something similar to the porsche vid. Why couldn't MaZeR modify the function so torque is limited when wheel spin is detected, torque is limited in say 2 degree increments sequentially until wheel spin is back under control. If it's a single wheel losing traction, an adjusted ASR function could take care of that but how it normally does with the brakes. I know this is like way over ambitious/complicated, but I've wanted inside the ABS module for a long time, I think there's some launch secrets to be had in there. I just don't have the ability to reverse engineer like that.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: phila_dot on April 11, 2014, 09:19:58 AM
This is already a function of the ECU.

The ECU only receives a torque request from the ABS module and responds with torque intervention.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: Snow Trooper on April 11, 2014, 11:00:43 AM
You want some wheel spin.  You also do not want the brakes.  People are over thinking this.  The new function is just about perfect, its up to you to get it setup for your application, which isn't hard.

You want some wheel spin.  You also do not want the brakes.  People are over thinking this.  The new function is just about perfect, its up to you to get it setup for your application, which isn't hard.

My understanding is you want to be as close to the threshold of breaking traction as possible = "some wheel spin". I get that, but I'm talking about after the initial launch but still in first gear. I want to hold WOT from launch to end of the run. right now first gear @ WOT is all spin city after launch and I have to feather the pedal. I Know about the function to limit load by gear but as speed picks up so will the amount of load required to maintain acceleration. What if i need to only limit load to like 25% until 3500 rpm where i can increase the amount of available load because I'm no longer losing traction but i can still accelerate faster. The need for more load is dynamic in this situation and you can only limit the load by a percentage of max load IIRC in that function. I want a way for the computer instead of my request to ramp load up as acceleration and speed increases as it would take out operator error. yea yea "learn some drag racing skills" right? well its what everyone else is going to it seems...the guy in the porsche vid holds it to the floor and doesn't let up at all. how are we going to compete with that? just put an even bigger turbo on it and play catch up? That does sound fun too though lol

Shannon, you are still overthinking it. Reduce the ignition angle that is used for launch control until you achieve a boost level that is condusive to launching.

Because you need to keep the function active until 15 mph or so.  I have been telling people that one for a while.  On awd cars I keep it active until 8-10 mph.

Is the new code harsh like the old, or does the engine just kind of lay down under load until you launch?

LOL yeah... still putting it back together between paying jobs...

For those curious, I had a bit of a mishap with some very aggressive settings on this new code, I overlooked the fact that my cam settings allowed advance/overlap during ALS and well, the intake manifold doesnt handle explosive energy as well as the exhaust manifolds and turbo does.  So after sending the booms the wrong direction through my engine I can say with confidence you dont want that to happen.
Can you post some what NOT to do settings?  Do you have any carnage pics? I'm totally imagining your intake exploding to pieces like a grenade.

Are you guys still looking for more testers for the new code? I've got an A6 (ME7.1.1) running on the old code currently and am seeing 9-12 degrees of timing retard during AL/NLS, I'd love to test out the updated function & will get you guys any logs you need!

Has anyone tried to do this with older ECUs? I'm changing from 8d0907557 to 8d0907557T and I would be interested to implement AL for those random standing start occations. Engine is AEB 1.8T DBC.
I know that benefits of this are somewhat minimal on FWD cars but would be interesting to try  :D
I assume that the compiled assembly wont work directly as cpu is different

Hello guys!

I have a little problem. :-(
Because I was not able to add the LC function by myself, I payed a professional chip tuner to do it for me.
Unfortunately he can't make it work. He is working on it for two weeks now.
I loaded the original file with Nefmoto from my friends ECU.
I also wrote the file with Nefmoto. There are no errors while writing and the car even runs after writing.
But no launch control.... :-(

I attached the the original file I've loaded from my friends ECU and the MOD file from my chip tuner.
The car is a 2004 Skoda Oktavia RS 1.8T UK Edition. (It has been remapped already...)

Can you experts please have a look on both files and tell me whats wrong?
I could imagine that the checksum correction has destroyed a part of the additional LC code.
But I dont know how to check that.

So please.... please help me :-)

Adam posted that his file (also 032HN) has antilag and NLS. Is that not sufficient? Hell, I was even going to do this for you until I dl'd your files and found a noread tag. If you want help, make it easy on the person.

I'm sorry. You're right...

But it's just so annoying for me because I payed for a non working File and my friend is not going to pay me, because LC is not working on his car.  :(
It's like putting 200$ into a mixer and push the button.  >:(

@adam-

LC and NLS is working on your ECU without burning the coils ?

Could you please have a look at my two files ?
Maybe you can find the error.

Now I added the files without Noread tag.


I can't upload files. Is there a server problem ?

Thanx very much for the XDF Marty !

I did not realize that these files are not the same. But now I know !

I dont wanted the tuner to modify the file like this. He just had to add the lc function.
It looks like he took a totaly different file and not my.

Now I attached the files without Noread.

I've made some screenshots of my .mod file.

I think the chiptuner got me wrong... there is no modification at the AL/NLS maps.

Can I do copy & paste from an another file ?

Post by: UM-Olli-92 on August 08, 2014, 07:16:47 AM
OK I understand.


I checked it with the difference Tool of Tunerpro.

The first thing thats different (exept the maps caught by the xdf) ist from adress:

12800 - 12802

the next is from: 15C36 - 165A7

then from: 16872 - 16873

and the last is from: 1F444 - FFFE6


Can you guys maybe help me finding out whats hiding behind that ?
If thats the code my Chiptuner used or not for Launch Control.

If not he definitely got me wrong, I think.

There is no code for NLS/LC at all. Also , your tuner or whoever did that probably has a wrong definition file ,in a lot of maps he misses the last column/row. Anyway there is a lot info here to create your own ,read ,create one and post it people will help you

After running the car and the throttle lights up the check and epc
Yes I think temperature was over 75°C because, car was the 30 km route, and before flashing the mod was about 15 min. I did not have too much time to check the logs. As I had some free time I will update the topic and give the logs.

You are using another way to addressing tmotlin.. Ok. Thank you. I will try it.
But why launch implementation via launch.php have movb    word_384FF0, rl4 instead of mov     word_384FF0, r4 ? or it is the same i think

Not the same. movb will only store 8bit.
Try and Report :)

i know, i mean the same in this implementation - low byte of counter or a word of counter/ If counter <255, this is the same
Thanks mazer! your code works! it seems what tmotlin addressing in launch programm are wrong...

Try this and report please.
Im running this ecu on my car since half year without problems of rsa or something.

I think this sw version does not have the rsa algo as others do...For example new binaries with rsa contain this hex values

c1 47 fc 10 00 8d eb 98 60 db 00 xx xx xx xx

And in those versions the older code that was described in the pdf has the same problems as the php launch exe or the tool i made for injection.

Can anybody explain this? If I search in hex editor neo I can find f3 f8, and it's p re try close to the same address, but not. Why is that? Should I just replace the f3 f8 and the two next blocks anyways? Then put the code at the applicable addtess shown on the first page?

The auto add script hasn't worked for me thus far on anything.....please advise. I am modifying that file downloaded from this site if you search thst ecm part number.

I have a wotbox in the car. It works when i enable the launch control and no lift shift there.

Problem is i have a GT35 in the car and cannot get it off the line as the car does not build enough boost.

Not sure if the changes i made are only for the ME7 units or can it work on the MED9.

Read many posts regarding AL/NLS and i do not see anything with regards to this...

The code should be placed in empty space?  That doesn't look like empty space. 

I don't see a reason why it wouldn't work with MED9x with a little work.  Find some empty space in the file, point the script to this and let it do it's business.  Does it find the rest of the variables okay?

Yes it does. The values were edited. But worried that it might not be the same fields as ME7. I also cannot find the fields F3 F8 F3 8A

I don't think you've done enough reading before attempting this, hence the reason for your failure. If you can't understand that MED9 uses a different CPU than ME7.x and that the assembly language for it is totally different, then you should first stick to getting your head around it, then try. And yes, I do also think you're ruining this thread with useless/pointless discussions that will not get you ANY further until you've understood the differences between MED9 and ME7.

I found someone on MHHAUTO.com promoting an online app to add ALNLS to bins., Its free for testers, but he's planning on making it a pay service. bogus. Here are the quotes from the post. He goes by The.d0xX

I know we're all editing someone elses code in some shape or form, but using this forum to profit without any real effort is pretty lame. Especially if he's not offering it here for free, like the groups knowledge and effort that he is milking.

"This is my first post, so i hope, the thread is in the right section.

I programmed a tool, which allows you to add launch control & no-lift-shift to most ME7.X dumps.

It's hosted online, and works without any waiting time."

"PS: In this version, it uses "Setzis" launch control code from nefmoto. I got a new updated base-code, and will add it to the script in the future."

Sorry for the rant.

Hello i have a problèm to add the anti lag fonction in the flash 032DR (golf 4 1.8T)

I'm using the script for add the fonction and correcting cheksum with winols. I upload the file in the ecu. The upload finish, the engine doesn't start. If i'm modified the file generate by the scrip in winols (change  the rpm single for the launch control for exemple) when i'm flash ecu, the upload finish 100% but the ecu bricked.... i'm restore it in boot mode with the original files. Winols say me the cheksul is correct in this files, ME7Check.exe too....

Anyone have a same problème  ?

I belive you got what is called the death code.
Meaning you got bad checksum in your eeprom.
You need to remove it manually in HEX and recalculate checksums before flashing your eeprom again.

I have this same problem, might work fine with one rpm value but if I go and change launch RPM, no start. Have to bootmode flash after that. Winols and ME7Check don't find anything wrong with the file, I'm guessing the script does its thing somewhere it shouldn't. Have You tried manually setting the free space addresses?

This issue can be fixed with a single opcode patch in flash without even removing the ECU from the car... It will even repair the EEPROM for you by itself.
Done this plenty of times at this point.

If you are going to read the EEPROM then search this forum for "Death Code". You should find what you need to change there to fix it.

I need a sanity check here. I've been trying to implement this to a 4D0907559D binary. And before You point and laugh, yeah I DO  KNOW it's a N/A car  :P

All I'm looking for is a little showbiz when launching, winter is coming and I frequently go to ice track days. NLS rpm would be set to 10000 or something like that.

I've tried the launch.exe method, both the older version and the later which has tmotlin also. I've tried adding everything by hand using the pdf instruction file as a guide, although afterwards I compared and everything was 100% identical with the modifications done by the launch script.

I've tried FTOMN 0, 1, 2 with no difference, changing LC rpm doesn't make any difference. The LC just doesn't work, when I press throttle pedal, the revs rise like on a stock file. I presume the clutch switch is working because cruise control drops off when I press clutch.

Can somebody please verify my work. I've been trying to get this to work for a week now and frankly have ran out of ideas. I'll promise to immediately upload a video of a de-cat 4.2 V8 launch :)


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: hopsis on October 16, 2015, 09:12:04 AM
OK. Got LC working, not on the abovementioned ecu though. I did something I swore I'd never do and dug my spare ecu from back of the glove box (i've even written a sticker on top saying "DO NOT TOUCH!". It's a 400BB 512kt (the one I'm normally using is 800BB 1024kt). Read the file, ran launch script, fiddled a bit with launch rpm and changed FTOMN to 1, flashed and what do you know, worked at first try.

No flames though, must be too much restriction on the exhaust boxes  :-\

One thing I noticed, while the car now holds the LC rpm as it should, the exhaust note changes a lot depending on the throttle pedal position. Around 50% throttle it sounds crisp and rattles/pops nicely but if I floor it, the sound gets all Isaac Hayes. I currently only tested it with 3000 and 3500rpm, its getting late here and I'm guessing the neighbors aren't as interested in the slighter nuances of my cars exhaust note :)

I know you are doing this just for fun, but a standard rev limiter is going to be much more effective (not to mention safer) on an NA car. You're just heating up things that really shouldn't get heated up on an NA car.

Which things do You mean nyet? I'm thinking exhaust valves and manifolds as they probably aren't designed or made as robust as FI parts. Apart from those I don't know what's different.

I had the standard limiter last winter, nothing wrong with that. I don't plan on using this for actual launching, just for showing off for friends once in a while.

really hate to be double posting but im not sure where i belong to figure this one out. been working or getting the LC/NLS to work in a 2000 beetle 1.8T. its the 512K ECU by the way too. i used the last posted version of launch.exe to patch it originally and it did patch the BIN but it did not work. i took a look at it in IDA to see what happened and it looked to me like the first block was comparing coolant temp to the second bit in the TPS constant. after that it seemed just like any other 1mb LC patch. so i deleted the line of code pertaining to that block and shifted the code up to the original start point, saved and corrected the checksum. now it looks proper in IDA but it kind of works on the car. i can hear it start cutting ignition at 4500rpm but it pushes through to the rev limiter. im not sure what needs to be done to correct this so i figured i would consult the makers. i posted in the auto patch thread about this too and hopefully if i can get it working the auto patch program can be fixed so this doesnt happen. also i checked my clutch switch in group 66 in VCDS and it is verified as working.

i attached both a stock file that was patched with launch.exe and the one i modified that semi works.

Sound like a great idea :)  And fun!  Let´s Do THis!  Is there any video on this working?

Meh, I was a bit disappointed on the outcome. Decatted downpipes but stock exhaust with stock mufflers so not much drama. I'll try to get a good launch video some day.

This issue can be fixed with a single opcode patch in flash without even removing the ECU from the car... It will even repair the EEPROM for you by itself.
Done this plenty of times at this point.

If you are going to read the EEPROM then search this forum for "Death Code". You should find what you need to change there to fix it.

I test reading eeprom by obd but non work :(

How to repar it by the flash ?

launch.exe 8N0906018J_matrix.bin 8N0906018J_matrix.ecu a1910 17b00

try the file i attached and report is working or not.



I didn't get it working on this ecu too
I tried your version too mazer
Engine stalls and epc is on off
Would like to have it on my car

Writing a single byte to it without correct checksum should do that too.

Season's Greetings fellas!

First - thanks to Setzi for the excellent cleanup and modification of the original routine.  

I'm a few years late to this party but have used some holiday downtime to do some disassembling whilst learning to code custom ME7 subroutines.
  
I believe I've found an error in the NLS Ignition-cut-duration counter of this code.  http://nefariousmotorsports.com/forum/index.php?topic=607.msg5283#msg5283 (http://nefariousmotorsports.com/forum/index.php?topic=607.msg5283#msg5283)

I am very new to IDApro and C167 ASM in general so I am posting this in all humility and am quite open to the idea that my analysis is incorrect.

As the line stands - it moves *byte* r14 value to *word* RAM variable 0x384FF0. At this point r14 = normal ignition closing time (coil dwell time) from tsrldyn as it was in ZUESZ before CALLS to this SUB.  I disassembled the earlier iteration of this function (as posted in this thread) and noted that it made use of r14 and an additional RAM location 0x384FF2 as a counter.  It seems that with the clean-up and addition of supplemental criteria to v.2 of the function, r14 somehow made its way into the v.2 code (even though its value is neither set nor referenced anywhere in this function save for the original line from ZUESZ before RETS).  

So -- long story short - this code does not compare an additive counter (add  r4, #1) to ConfigurableIgnitionCutDuration stored at location 0x817E04 (as I believe is the desired behavior) but, rather, compares *byte* r14 (which at this point contains whatever ignition closing time in ZUESZ happens to be) to *word* ConfigurableIgnitionCutDuration.

What does this mean in the real world --?  Effectively, I don't know that it means all that much beyond not having too much control over the duration of IgnitionCut.  In either case (counting r4++ until we reach ConfigurableIgnitionCutDuration or having an incorrect comparison with r14 serendipitously controlling when ignition is cut) we are oscillating between no ignition and normal ignition.  As soon as the comparison is satisfied we return to normal ignition for a moment only to be returned to the NLS function and if the clutch is still depressed and wped > X = ignition is cut again.  

If I am correct and there is an error in the coding of the counter - the functioning of the ignition cut during NLS is less than ideal and is bound to be more staccato than necessary, perhaps lending to the onset of knock.

In any event, there is an important realization here. Normal ignition *is* sporadically being attempted in the midst of everything.  Many of you have logged Knock Regulation during NLS and the consensus was that it was the result of false identification because how could Knock occur with no ignition.  Ignition is certainly occurring (even when this function is performing as designed) sporadically between exiting and entering NLS (otherwise the motor would stop) and it must be that actual Knock (or the approach of Knock) is being detected and that is where the excessive correction factors are coming from.

As has been said previously - the correct method of limiting engine speed during AL/NLS is with ignition retard, not oscillating between normal ignition and no ignition.  Regardless, I must say that examination (and enhancement) of this function by the community has been invaluable!  So -- many thanks to all of you crazy, brilliant guys :)

Please chime in anyone if you can confirm or dispute my findings.

Lastly - I do not think that it is wise to disable Knock Regulation in conjunction with an Ignition Cut model of AL/NLS and while it is acceptable to disable KR with an Ignition Retard model, I am finding that it is not necessary.

Happy New Year!!!

As the line stands - it moves *byte* r14 value to *word* RAM variable 0x384FF0.
The infamous rl4 (rL4) vs r14 strikes again?

rl4 is lower byte of r4 which in this code works just fine since NLScounter is not expected to exceed 256.

Lastly - I do not think that it is wise to disable Knock Regulation in conjunction with an Ignition Cut model of AL/NLS and while it is acceptable to disable KR with an Ignition Retard model, I am finding that it is not necessary.
Why would you need KR during AL when there is no load?

YES!

Thank you.  This made no sense to me.  Thanks for posting. In both IDA and uVision r14 appears near identical to rl4.

Would

mov   word_384FF0, r4

work as well?

Do you think that the experienced Knock Regulation is not in response to actual knock but just 'noise' from the ignition cut commotion?

Problem with blown ECU fuse returns on my 551C euro S4. Launch control had activated and pops maybe 3 times (about 2 seconds) and 15A ECU fuse was blown and engine cut out. Launch control RPM is 4500.
Anybody solve the problem? It is due to the fact that maybe knock is recognized and much retard timing required high coil dwell time and blow fuse or what? Is there any solution?

I've successfully patched my D-box with AL/NLS using launch php/exe tool (congrats to all who contributed), I tried following settings with different results:

FTMON 0
launchRPM from 3000 to 4500 (step 500)
cutDuration from 200 to 600

- this kept blowing out fuses, rmp was really unstable and it kept building up revs until the real lmiter kicked in.

FTMON 0.2
launchRPM 3500
cutDuration 200

- a lot of noise, not a lot of boost

FTMON 0.1
launchRPM 4000
cutDuration 120

- this gives best results, still a lot of noise but the boost is really easy to manage with throttle position, boost build-up to 0.4BAR takes about 1.5sec.

It would be really cool if the whole procedure could be enabled/disabled by some external switch, for example my car is striped out and has the AC removed, but the switch (and I assume the signal from AC Controller to the ECU) is still there and operational. Do you think that it is possible to implement?

I am going to try to make NLS be more like a real ALS that works on up-shifts and down-shifts, therefore it would be good to have a simple on/off switch.


Title: Re: Anti-lag launch and no-lift-shift secrets inside

And this is how it works 1/3 throttle while stationary

https://www.youtube.com/watch?v=wpIyiikFW7k (https://www.youtube.com/watch?v=wpIyiikFW7k)

But NLS doesn't work, I tried to set the throttle position to 0 but it doesn't change anything. Launch control disenagages at 3km/h so I guess it's not that, and the current engine revs are also properly detected otherwise LC wouldn't work as well.

I finally managed to get the NLS working, stupid D-box has inverse brake signal, so in ECUs mind I was constantly braking, thats why it didn't work.

I've attached how it looks in the logs from a rolling start from 2nd -> 3rd -> 4th.

I enjoyed your videos :-) You would have to rewrite the function to do this, but for sure it is possible to replace the routine startup conditions (temp+pedal) with a 5v or 12v switch that you connect to any unused I/O port of the ecu. For example secondary lambda. That is, if you can write functions in assembly. (I still cant)

I ran launch.exe over my 1ML906032A file and everything seems fine. No errors there.
Checksum corrected and flashed to my ECU.

But nothing works :(
No AL, no NLS

Can anyone take a look to my file and can tell me where the fault is?!

Much thanks.

Hey Guys...
Thanks for your help but i found the fault by myself...

For each other guys i attached a picture with the difference in the code...
Seems the script wrote something wrong in it because i don´t know what the first line is and the hole code is too long, too.

I compared my files with a bin from another ecu where ALNLS works so i found the mismatch.

Corrected this, everything works fine!!!

Perhaps anyone can tell me what the first line in the wrong code means?!

Best regards to you all,

Hey Guys...
Thanks for your help but i found the fault by myself...

For each other guys i attached a picture with the difference in the code...
Seems the script wrote something wrong in it because i don´t know what the first line is and the hole code is too long, too.

I compared my files with a bin from another ecu where ALNLS works so i found the mismatch.

I am running in the exact same problem here, and I just noticed the same thing has been done in my bin. I see you just deleted the line and moved it up.
Going to edit it now, flash and update what happens!

Cheers

Awesome! Got it working now. Thanks a bunch.
I feel like a kid in the candystore  :D

What I do not understand is where is this "C2 F4 etc.." line is coming from because as far as I am looking in the php file I cannot find any matching with that. Also I do not find the whole code in it but its because I dont understand php to well.

Going to log some next week because I am going out this weekend.

there is other patch available for a more violent als & nls ? i see matzer gti has talk about a new version ? is it release ?
i can pay for it if not free.

I got it at 200ms and thats giving me 0,5-0,6 bar of boost on AL. Maybe with some tweaking more boost is possible but havent tried it yet.

Finally I got some time to log, Im very happy with the results.

Hello,
The patch doesn't work on this dump(032RA). Its me7.1.1 1.8t vw beetle.
Can someone tell me, at what address should i call (DA) the function?
Thank you

I have done manually.
Attached is the LC version.
Also i have modified the php script to work with this type of ecus.
Be careful, use this patch only to add LC on 1.8T Me7.1.1 ecus(size=1024). It won't work for the rest me7.5 after my modification.
Use the standard php patch for the rest.

Hi all

Just curious if you guys have logged knock whilst using NLS. I get some 6-9degrees of retard.
During NLS there is none cause the function disables knock detection however right after clutch is reengaged and next gear is set in log, it pulls timing for a moment. I can feel the power being reduced for a moment and then it goes again.
I have reduced KFZW to test, but no difference. Otherwise my timing is not near knock threshold and runs strong.

I finally managed to get the NLS working, stupid D-box has inverse brake signal, so in ECUs mind I was constantly braking, thats why it didn't work.


Hi, i have euro D-box too. Is it possible to remove brake signal check in NLS function?

Hey...
I don´t have very big experience with this but i miss the code itself in your file! It seems that you only changed the values for AL/NLS...
You´ve to add the code (and the call function)!

It´s not very hard to add AL/NLS... No one wanted to help me when i want to have AL/NLS, i´ve done a lot of reading and found an error in the script and told it here. You can read this in this thread. If you´ve done this you´re easily able to add AL/NLS correctly! 

Don´t flash the Al-NLS-LC file! You haven´t correct the checksums! Me7check says it has 4 Errors!

You´ve to run the script to add the code to your file if you´re not able to do it manually.

It´s called "2stepscript-master" if i remember correctly.
The you´ve to change a little thing in your file... Look a page before... I explained what script does wrong (i don´t know if there´s an updated version of the script, read carefully!).

I could copy everything except WinOLS with "counter," I'll go test.

To change the subject, running a AUM engine with a drive by wire throttle. For my particular application I want to hold the car on the start line, at low to medium revs (2500 t0 3000), build up the mass air flow, then launch the car with minimum wheel spin on a loose or slippy surface.
Having a minimum engine "load" registered, the throttle pedal is not directly corolated to the throttle plate resulting in a reduced mass flow of air through the engine even if the engine revs are increasing. A solution to this is to introduce a load to the engine system by engaging a gear and running the engine against locked brakes, this loads up the management system, the engine believes it is under load and the throttle plate opens giving more air mass flow.
See enclosed graph Overall Test in Satstart logger spreadsheet.
The question is can the throttle plate be controlled during the launch control proceedure?

I'm sorry you spent 6.5 secs against your brakes?? Do you have something personal against the clutch or just the whole transmission in general?

There's no need to reverse engineer common sense.


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: goffa1 on October 18, 2016, 01:24:03 AM
For a turbo engine with a drive by wire system the ecu is the link between the throttle pedal position and the throttle plate position. If the ecu see,s no (engine torque) load then the engine can rev up using as little air mass as possible to achieve the desired engine speed. If a load (torque) against the engine is introduced then the ecu reacts, it see,s the load and more energy (i.e. mass air flow) is created by the engine to balance out against the applied load. Example if starting on a steep uphill incline, the engine has to produce greater "torque" per engine revolution in order to accelerate the vehicle uphill. For launch control it is desirable to maximise the air mass flow rate ( i.e. spool up the turbo) to create the best achievable torque at the lowest practical engine revs. After all it is available engine torque that accelerates the the vehicle.

My query: is it possible to to control the throttle plate angle independent of the throttle pedal position during launch control and throttle over run / over boost?


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: TijnCU on October 18, 2016, 04:20:21 AM
The current public form of this antilag routine does not include throttleplate control, it is only a hardcut on the ignition while keeping fuel on. Maybe if you would artificially request load during the routine, the ecu would open the throttle more, or if you hardcode the throttleplate angle during the routine... The problem is you would have to think about a lot of ME7 safety features that have to be manipulated or disabled.
I also think it would become very violent, since the current form already makes big explosions with only minimal throttle.
Mazer has been working on a new routine that was more aggressive in the tests, but I think this work will not be made public to the forum since there has been no word about it since. Maybe the testcars have exploded the turbo's and manifolds  :D
 If you feel capable to rework the routine publicly, go ahead  ;D I would be interested to see if the results of hardware damage on stock engines will cause less new people to ask about this ultra popular code modification :P


Title: Re: Anti-lag launch and no-lift-shift secrets inside
Post by: prj on October 18, 2016, 06:02:57 AM
@TijnCU - with the current LC routine the throttle is already wide open. To build more boost ignition retard needs to be introduced.
As for the guy above you - please read a book about the basic operation of an internal combustion engine, because you got some stuff WAY wrong.

What are the best settings for a "smoother" anti lag? Im using FTOMN 0.2 and 3500rpm for launchRPM, have 3" downpipe and 2,5" exhaust. Atm its hitting too hard, feels like soft launch for 1 to 2s then suddenly throws a huge fire shot, usually just one.
I would like to make it more linear and smoother, like frequent "medium" pops, not one huge alone. Its not building boots this way.

I have a MK4 GTI AUQ 2002 (06a906032hp), from what I know (correct me if I'm wrong) it is 29F800BB, the bin is 1024kb
My coils are R0501S00500 (A4/A6 B6 2.0 20v and 3.0 V6) not TFSI (longer ones), am I good with those coils? Is the DWELL time different on them than the stock coils (built in driver)?
Im good with FTOMN 0? Heard a lot of people (018 512kb) with dead coils after ftomn 0. Just to be sure, coils are expensive here in Brazil.

Im sorry to bother you guys, and also very thankful to you guys. Learned a lot here.
