Title: The 5120 hack - Running up to 5bar absolute pressure on ME7.x
Post by: Bische on January 08, 2013, 11:43:22 AM
As we all know there is a pressure cap in ME7.x at 2560mBar absolute pressure, this has in the past prevented us from installing a higher reading MAP sensor than the stock 2.5bar sensor.

This hack is based around scaling EVERY pressure variable down by 50%, this puts the pressure cap at double stock, 5120mBar absolute pressure. This allows us to install a MAP sensor capabable of reading up to 5bar absolute pressure.

There is one known downside of doing this, it cuts resolution in half. The stock resolution is at 0.01bar or 10mBar, after scaling all pressures by -50% we end up with a resolution of 0.02bar or 20mBar. As you can tell the loss is minimal since the stock resolution was as high.

Im attaching an .ols file with my stock ME7.5 8E0909518M bin, one version with the scaling implemented + definitions for those maps/ASM divisions. Im also attaching a .txt list of the maps changed(both .txt and .ols are sorted by %module), and last a graph from my car showing this hack in action.  ;D


A BIG thank you to all people involved to make this happen! Progress up to this point, can be viewed here: http://nefariousmotorsports.com/forum/index.php?topic=2747.0title= (http://nefariousmotorsports.com/forum/index.php?topic=2747.0title=)

I will update this first post as we go, when my 4bar sensor arrives etc.

Update 2013-02-07: BT contributes with 551M files --> http://nefariousmotorsports.com/forum/index.php?topic=3027.msg31965#msg31965 (http://nefariousmotorsports.com/forum/index.php?topic=3027.msg31965#msg31965)

Update 2013-02-26: List updated.

Update 2013-04-04: Graph showing 26psi being PID controlled.

Latest 2.7t (8D0) M-box reference bins (as of 2015-07-15) (Big thanks to britishturbo!)

Note that the britishturbo files (http://nefariousmotorsports.com/forum/index.php?topic=3027.msg31965#msg31965) have a few minor errors:

http://nefariousmotorsports.com/forum/index.php?topic=3027.msg63024#msg63024

Added my changed files below, along with definitions with scaled factors, maps, and various code changes.

HERO POST!

Thank you bische!

Thank you guys on here for this forum!

I want to add this, the changes I made is made to fit my 1.8t '02 Audi, there is more maps that could be needed to scale in other applications that were not in use in binary - these maps are NOT on the list or in the .ols.

And this:
Quote
WARNING!

Before attempting any pressure scaling you must check if your car uses brake force amplifier(%GGPBKV)!

I just became aware of this, and if this function is in use it must be scaled. I dont really know what would happen if not scaled, but I dont want anyone to have their brakes messed up!

In the 1.8t and S4 2.7 binarys I have with this bit defined, it is CWGGPBKV = 6dec. 6dec = Brake amplifier function turned off.

Please verify your CWGGPBKV in %GGPBKV if you are going to scale the file.

BTW i've been meaning to post this but forgot

It's a dump of the S4 g-box damos, converted to csv, and searching for references to pressure.

I just started digging in tonight.

I'm pretty sure I have all of the ATM constants for the M box. Now to start tracking variables.

Everyone that says that they want to help can contribute by compiling a list of all of the pressure variables.

I have taken a look at this list, there is alot of maps from the brake amplifier module %GGPBKV, if those need scaling or not is different between applications. You will have to check in your binary if this module is use to determine if scaling is needed --> http://nefariousmotorsports.com/forum/index.php?topic=3027.msg29820#msg29820 (http://nefariousmotorsports.com/forum/index.php?topic=3027.msg29820#msg29820)

I also did trace the pus_w(PUSMAX/MIN in nyet's .csv), it is used for EVAP Leak detection pump, it goes like this:

pus_w -> %BGPUK (to determine if ambient pressure is sane), out comes pukor_w and pukorv_w -> %DLDP, which is diagnosis for LDP.

My file does not diagnose LDP (CDLDP = 0), so I did not follow up what impact the scaled pus_w would have. But if one have %DLDP active, you might want to follow it up :)

i believe you have a typo in your ols project. Positive limit for pssol gradient (PSSOLNGRD)
should be Positive limit for pssol gradient (PSSOLPGRD) im assuming.

yea, well, not to split hairs but pretty sure you have a few maps in the text file that are not listed in the ols.
only reason i mention is because im going through the ols, txt, and my 018ch file.
maybe i just missed them. ill check more. :)

No you are right, I have just forgotten to mention that. The maps regarding the DV operation I have not scaled, I did spend an amount of time to find those stubborn bastards and had some resistance, so I moved on through the list.

I have not gotten back to those maps, when I do I will update the .ols with the definitions and changes.

I updated the typo in the current .ols btw

ok, thanks for the clarification. just making sure i wasnt going blind.
so, there are maps that are ok to leave out and not scale?
im assuming all the ones you have not added to the ols?

NP man :)

Well it is up to the user to decide which maps he/she want to scale, some of them are not "needed" for this work, but if not scaled the driving experience can be greatly compromised lol :)

The maps I have not scaled is those n249 DV related maps, not scaling them down will make threshold for DV actuation from the vac reservoir less responsive on paper. I viewed my logs and didnt see any signs of boost blow-off being "slow", so I skipped them going after the negative turbo load maps instead(which gave me some awkward jerkiness).

And I have not gone back to get those maps, when I do, I will update the .ols.

It was ps_w, that variable is also scaled with this hack.

If your file already have 16bit load axes in your timing maps, I cant come to think of any more limits :)




...aaaand I have a 4bar TDI MAP sensor on the kitchen counter, but I must not touch it..

Correct.  I need to send him the standard file to see if his de-immo procedure will work or not.
My car has a m-box running on a A6 Z-box, therefore the eeprom was already de-immo'ed at some point, but I just don't have a de-immo'ed rom cleaned up yet.

I have no plans of moving to any RS4 box. Too many hardware differences IMO.

I can easily get 16 bit load axis' on S4 software.

Not necessarily the case. If the m-box was flashed over the original z while the ecu was still in the car the immo might still be activated in the eeprom. Flashing a bin with the immo referenced may very well end in a no start.

No RS4 cams and no RS4 heads makes RS4 software more a pain than anything else.

For me, the fact that the RS4 file is based on different hardware is great, as I've got big port heads and 2.8 cams (pretty much the same as RS4).  On top of that, the 16bit axes already done, better base values to start with, the added function of the RS4 airbox flapper output that I can utilize for meth/nitrous/second fuel pump, and all of the immo setup so I can activate immo on my non-immo car.  It's pretty much all upsides for me. :)

I have all of nyets maps found and only have 8 or 9 of Bische's left to find. Should get those finished tonight.
Then I'll make an xdf and then it's testing time tomorrow hopefully!

Thanks to all those who pushed me towards doing it all myself :-)

Thanks man. It has been a little easier than I expected but very tedious lol.
All the 2.7 boxes should be pretty easy to do once I have the M box done.
And more than likely all the me7.5 boxes are probably easy too.

The other guys here did all the hard work!

I have been thinking about preparing a 551K to be flashed on 551D boxes(all "stock" basefile for our euro S4's) with the 5120 and all modules required, swapped to D box spec. Seems to me like I would be dealing with alot of modules to get it set up, intake model, LDRPID, KRRA and so on, enough to be questionable worth the hassle?

It would sure be nice since theres such good definitions on the K box, but also ALOT of work...

Once I prove out all the 551M box I was going to look at the K box. If its as close to the M box as the G Box it will be easy to find all the 5120 locations.

Its not the 5120 im concerned about, it is taking the RS4 binary and rework it to S4 spec just for the definition and 16bit KFZW axis. Well, it is a one time job, but time is indeed time :)

My intentions with the K-box aren't quite as noble as yours, as I'm just looking to get a K-box file that will work with my car the best (not necessarily set up a template K-box bin with stock S4 values).  Since my car's hardware is much closer to the RS4's hardware than it is to the S4's, I wouldn't be changing much, and certain things that I do change would be changed (tuned) either way (for example LDRPID, as I'm running 38mm Tial external wastegates), regardless of whether I started out with an M or K box. KRRA and possibly one or two other things will need to be taken to stock S4 values, sure, but everything else should be either left alone at stock RS4 value or tuned for my specific setup.  I'd rather do the couple of things to run a K-box on my car, than to modify an M-box to have 16bit axes, hack it to have all of the immobilizer stuff, hack it to have new outputs via unused ECU pins, go through and plug in the corresponding RS4 map values that I want in my file (which I can't even do with some things [like NWS], as some of the schemes are completely different).  For my personal build/application and desires, it seems that the path of least resistance is to switch to a K-box based file.

It is not yet working, it seems that there is more to the 5120 "hack" on the ME7.1 than on the ME7.5.

The car would fire up and would pop and bang and want to run at a higher throttle angle than expected.
I'm analyzing the logs right now. One thing I see is that fho_w is 1/4 what is normal not 1/2... so I'm debugging that right now to see where that came from :-)
I'll fix one thing at a time ;-)

Here's a test run this evening... the Boost is really double what it shows (It isn't showing the scaled Boost numbers but they were logged)

(http://i1357.photobucket.com/albums/q755/britishturbo/5-bar-map_m-box_zps0d525caa.png)

Awesome stuff!
I'll do some more testing and clean up the xdf file and upload everything tomorrow probably :-)

Thanks for all the hard work guys!
I should be able to do the rest of the 2.7T boxes very quickly if anyone has any requests...

Did you find anything applicable in m-box that bische didn't cover? Evap? Brake booster?

BTW you got a PM re:ME7Sum :)

The 5120 mods survived my 45 minute drive to work fine today... I do have a few slight differences in behaviour to look into though.
I've had LR turn off on me a few times that I need to investigate and it seemed like acceleration enrichment wasn't "quite" right, that needs looked into as well.

I believe it does... that's the two pins on the bottom section I think.
I'm guessing it's there but not used on the Audi 2.7... the harness only has the 2 wires for the MAP.
Either way it could be retrofitted and keep the IAT I think :-)

What for what? PID control?

How about ability to spool faster by over driving PID and letting car down regulate PID to reach desired level?
How about boost compensation due to IATs? (you do know that the hotter the air on fixed PID, the less boos turbo makes, right?)

Working PID might actually allow us to spool faster as you won't have to taper out KFDRL in fear of overshooting without safety of working PID control. It is huge IMHO.

Re: maf and map spike. It looks to me like you're not running n249 valve and backpressure literally backfires backwards through the whole intact tract giving you insane mar readings as maf can't indicate direction of flow, just g/s. With properly working n249/diverters, the charge kind of dissipates in closed loop inside intake.

You are correct about not running the N249... just a Tial Q50 BOV dumping to atmosphere. The MAP spike only shows up in 2nd gear actually, in higher gears it isn't there nearly as much, I'll post some logs later after I've analyzed them. There isn't any compressor surge when it happens though and the BOV is working correctly.

The MAF spikes are something totally different though, that was under WOT conditions, not on throttle release like the MAP spike. I think I may have discovered the problem though, I'm pretty sure the MAF cable was picking up electrical noise... I went and looked and the cable had slipped down and was laying on top of a coil pack... so i moved the cable and it's much much better than it was...

It really doesn't help that the VMP pigtail isn't shielded... the factory maf wiring is, so it goes from shielded to about 18 inches of un-shielded wiring. I think I need to remedy that with some shielded cable.

The log for the run is attached as well.
There was still a little noise on the maf in this file, I'm going to run a shielded cable tomorrow.
Also I need to smooth out the KFZW file as well, I wasn't hitting the places in the table before that I am now that things aren't underscaled...
Was also very rich here as well.
I'll have some new fresh better tuned logs tomorrow.

Just catching up on this thread, and thought I'd repost a post I made on AZ regarding the AEM sensor referenced a couple of pages back.

For those who don't care about factory fit Summit Racing gas an AEM 5 bar sensor for $63.

If you go with that AEM style sensor, I recommend the stainless one over the brass one (though it is twice the cost), as it's got an accuracy of +/- 0.5% rather than +/- 3% for the brass. 

http://www.aemelectronics.com/5-bar-75-psia-map-stainless-steel-sensor-kit-655 (http://www.aemelectronics.com/5-bar-75-psia-map-stainless-steel-sensor-kit-655)

Ultimate accuracy doesn't always matter, but when the scale is so large at 5bar (and people are likely to really only read up to less than 4 bar MAX on their S4), that added accuracy can add some meaningful resolution to the MAP readings.  The stainless version's accuracy equates to +/- 0.36 psi, and the brass version equates to +/- 2.175 psi.  A potential 4+ psi swing of inaccuracy is not insignificant when people are looking at values like 20 psi.  If you decide to go that route, let me know and I can hook you up on price with that sensor with my business accounts (though it looks like you've already got your solution).


My PM box got one message, a very humble one from someone who in my opinion threw down more than others in direct relation to my personal car.  I felt compelled to toss him some R&D funds. 
Thanks for the money Jared ;D

j/k

Real quick, who has what 2.7 boxes here so I know what other boxes to worry about making an xdf for?
I know M Box... I also have G Box pretty much done.
Should I do A box as well?

I agree with the above, there's no point in worrying about any additional North American xdf's other than the M-box.

So what is the most common Euro 2.7 Box?

As for the euro boxes, my vote (as usual ;D) goes for the K-box.

That will work perfectly, you just won't be able to install it "as oem"
But as far as functionality it will be fine.
The GM sensors have the same scales that I've seen as VAG / Motorola / Freescale sensors.

Sweet.

Quick question: IF I installed the 4bar map and only changed the relevant translation constants/tables for V to mbar conversion, I will be ok driving around prior to taking plunge into real conversion?

You might throw some codes unless you get the scales just right.

I mistakenly flashed a non 5120 file this morning and got every code imaginable for MAP sensor when it didn't see the right response :-P
Only took me about 50 feet of driving to realize lol.

If you go with that AEM style sensor, I recommend the stainless one over the brass one (though it is twice the cost), as it's got an accuracy of +/- 0.5% rather than +/- 3% for the brass. 

http://www.aemelectronics.com/5-bar-75-psia-map-stainless-steel-sensor-kit-655 (http://www.aemelectronics.com/5-bar-75-psia-map-stainless-steel-sensor-kit-655)

Ultimate accuracy doesn't always matter, but when the scale is so large at 5bar (and people are likely to really only read up to less than 4 bar MAX on their S4), that added accuracy can add some meaningful resolution to the MAP readings.  The stainless version's accuracy equates to +/- 0.36 psi, and the brass version equates to +/- 2.175 psi.  A potential 4+ psi swing of inaccuracy is not insignificant when people are looking at values like 20 psi.  If you decide to go that route, let me know and I can hook you up on price with that sensor with my business accounts (though it looks like you've already got your solution).

Are you sure this isn't just AEM sales BS?
I don't think I've seen any pressure sensor elements that have that bad an accuracy... I may be wrong though lol.
In general though I don't trust AEM hardware lol.

Inaccuracy meaning? Permanently skewed towards one end or at the same exact pressure the sensors gives constantly changing readings? First one is irrelevant, second is a game breaker.

This is very true... I might get one of these just to compare to the freescale sensor.

A little Google search finds lots of people agreeing with jibberjive.

You are correct about not running the N249... just a Tial Q50 BOV dumping to atmosphere.
Have fun with your mass-flow setup then.
BOV's are crap. They are either open at idle, or not soon enough.
A recirc valve can have a soft spring and be open at idle without any ill effects.

Actually other than the spike seen there the BOV is working great. No problems at all.
The original spring I had though was too soft and open at idle, so I went up to the next spring.
I think "crap" is a little over the top for a description of a BOV... in Speed Density or Blow Through MAF they have been shown to work just fine.
I guess we will just have to agree to disagree here ;-)

The spike is also not as long in duration as that log suggests, the output is smoothed in the logs that the picture was from. The raw ME7logger output doesn't look the same.
And as I already mentioned there is no compressor surge that is audible.
The spike is more than likely a result of the pure air volume the turbo is putting out at that time... Even a recirculating dump valve would have a hard time dumping that pressure and volume any quicker.

Snow Trooper: Thanks for your offer, but I do not want money for any of this.

I have taken and learned alot from this forum + made some very good contacts, I am just glad to be able to contribute back to the forum. I do not take full credit for making this happen, I would not be able to make it happen without the help of the others mentioned.

And as mentioned, there is still more work to it. The files I have posted is only a summarize of what I am currently running, with no known to me side effects, to show that this is possible to execute. I am also currently running the 4bar TDI sensor mentioned a few pages back now, once I manage to get good enough traction I will post up a graph of 24psi+ actual boost control.

Im glad to see more people working on this, hopefully getting this 100% ironed out and possibly spot more needed changes for different SW versions.

No. You just use a valve that is big enough, and these issues do not happen.

It's really the basics. You can disagree all you want, fact is that you need a stronger spring to keep it shut on idle or suck in unfiltered air.
Stronger spring - does not open soon enough when it should be.

Less efficiency, harder on the turbo, and makes MAF readings go all over the place. You should have the N249 actuating your BOV, instead of removing it.

To run the stock 2.5 bar sensor you divide DSLGRAD and DSLOFS by 2.
When I upload files later I'll have an M Box file for the stock 2.5 bar sensor and one for 4 bar sensor.

Note:

Logged pressure variables will now be half of their actual value using normal ecu logging.
The easy fix for this is to double the scale factor being used.
For ME7Logger this means the values in the .ecu file.
For example ps_w scale factor gets doubled to 0.078125

3 bar absolute. That takes into account atmospheric pressure, so your range is only an additional 2 bar.


Title: Re: The 5120 hack - Running up to 5bar absolute pressure on ME7.x
Post by: julex on February 07, 2013, 12:29:31 PM
3 bar would give you 2 * 14.9 = 29.8psi range. Good if you can keep yourself under 30psi but any larger aftermaket turbo can easily shoot outside of this range and you lose control then.

odd dyno queen cars I would assume. For 99% of people going all out, 40psi of boost is all they will run anyway. I am at 30psi now but once I upgrade y-pipe and ICs, I might bump it up but I doubt I will go 40psi unless I still see gains in TQ/HP department.

Can anyone double check my work who is a bit more up to speed with ASM work.

I did find more than one possible location for a couple variables so I may have selected the wrong one, or this ECU infact has more functions that needs scaling.

So this is untested and I warn anyone who wants to use this file to double check it first.

I've run through the map today made all the changes I can from the text file on first page for my friends car.  He was running 25psi on open loop but it was never that smooth to be honest, so we've dropped him to 1 bar boost at the moment put all the put a 3 bar map sensor in scaled it and verified its reading the same as the 2.5 bar did. Reset all the LDRPID stuff and so on.

Tomorrow we're just gonna try this file with the 5120 stuff patched in and see what happens unless someone can before tomorrow verify my asm change locations and tells me they're wrong. My only fear is crashing the ECU but hopefully if it doesn't run right it won't crash and we can just revert back a file version pending further investigation.

While going through the text file and scaling maps I noticed the Me1.5.5 doesn't have quite a few of the maps, either missing from my map pack or not in the ECU I'm not sure.. My only other thing to think about is whether there is any other additional maps this ecu might have.

Gotcha, wasn't quite sure  ;D

I guess 3 bar would be better than stock, but if you're already scaled to properly use a 5 bar it seems a waste of perfectly good headroom.

At the very least 4 bar, as I really doubt anyone running stock engine management would exceed that.

BTW-I credit this thread in bringing back a few long-absent members. I'm loving it.

I guess the only thing that really bugs me about this is fact that the sensors everybody is using has to be ordered from overseas.  I really would like the option of if the MAP sensor failed, my car not being out of commission, or having to carry around a stock Map file on my laptop all the time just in case.

How much boost do you plan on running?  I would like to be around 25psi without all the heartache.  I thought you would need the extra headroom to keep the PID happy.

Hey now, just about every performance part I have bought for my Audi was imported from your side of the pond, dont be spoiled about a €50 piece lol

What is the failure rate of a MAP sensor? Have your stock sensor failed since the car was new?

Im really happy more people getting around to run the 5120, Phila_dot have you found anything more that would need to be changed that is not on the list?

Yup, there's alot more. Once I get it all compiled and tested, I will post an XDF and bin file.

I agree about the MAP sensor, the failure rate is pretty low. For reference though, the VW 4 bar MAP was ~$90 to my door.

Here we go, file attached!

Here is what I believe the values to be:

50032 pvdk_w 1013 division #1
50696 pvdk_w 1013 division #2
50D7E fvpdkds 1013 division #1
50F42 fvpdkds 1013 division #2
5143E fho_w 1013 division
522E2 frhodkr_w 1013 division

I've tried these settings and we had some weird issues with throttle afterwards as if we're getting intervention.

But that said thing's were scaled properly and we were getting ~50KPA on boost request, actual and ambient pressure.

If anyone able to take a look at the bin I posted back on page 13 and see if I've got any of these wrong or whether they can find any others that need looking at?

What we also got the car thinking there was a boost issue.

Total number of fault codes: 1

P1106 - Boost Pressure Control Device Malfunction
 (09) - Present

So it's basically, after shipping/whatever:   3-bar is $50 and 4-bar is $100.
3-bar is 29 psi, is it worth the extra $50?  sure if you are a GT or 770.
i'd argue for 605 / FT you still will be 29 psi max.
certainly under it with most rs6 turbos too...

any thoughts?  does it matter if the community moves to one versus the other?

Sure thing, if you wont use 30psi+ thenstick to the 3bar sensor. You will retain better resolution also.

In my experience it is ps_w that tend to go out of hand and cause trouble, but not anymore :)

I was thinking alot at ps_w today at work, I feel ps_w shouldnt behave as it is, mimic'ing rl_w. From my understanding it is supposed to be modeled intake manifold pressure?

Yes and no. The problem with running a properly scaled MAF is that 99% of the time you are off the end of pretty much every single load axis.

Not that running an underscaled MAF actually fixes this (you're in the table, but just in the wrong row)...

Regardless if you rescale with unscaled MAF or leave alone and run underscaled MAF you lose resolution in load axis, no?

Unless you find a way to introduce more load points, the more load your engine generates, with fixed amount of load points, the more spacing the load points will require to cover full range.

Don't forget that Motronic interpolates between all those points.
You just need to distribute the points so that they cover most of the non-linear ranges.

Isn't this the whole benefit of switching to 16bit axis maps, so you essentially double your resolution (or rather don't have to halve the resolution if you were to double the range or whatever)?

I run 5120 hack for a day or two until my clutch took a dump (another engine pull under way) so I can't comment extensively but I believe I observed rather abrupt momentary SA transition when transitioning from positive boost to very light vacuum or 0psi (still tons of load on engine).

This manifested itself with abrupt jerk of car and AFRs on my gauge shooting up for split second. The normal operation would resume immediately but it is definitely noticeable

We must have missed some map/axis.

I might have logs but if not, I won't be able to log for another week, or so, until new clutch goes in. BTW I smoked 400-500 miles new twin disc clutch with zer olaunches on it and two not lift shifts. The night kevlar disc sheared all the pads off I was simply doing an U e-brake turn and dumped the clutch from about 4k rpms while on snow/ice. The disc basically sheared the pads off. What a POS.

I say this after every one of your posts like this, but I can't believe the terrible luck you've had.  And it hasn't been from any cut corners, as you've pretty much bought the most expensive hardware out (twin-disc, 3.0 liter, etc).  Your S4 is cursed.  What are you replacing it with, carbon discs?  And what does SA stand for?

SA is overrun fuel cut, some German word abbreviated.

Yeah, I use "SA" abbreviation to sound cool  8). Taken from overrun maps/variables/etc designators.

I don't believe my "luck" myself, I can pull the engine without thinking now and I don't even bag bolts anymore, I just throw them into a tray all together and can positively identify each one and where it is going :D. I took the engine out more times by now than I removed wheel on this car or changed oil during the time frame I own it.

CM gave me an offer to purchase new FX850 for cool $2000 which I might bite considering they retail north of 2500. Since I do have almost new sintered bronze discs for FX700, I will just pawn it off as a unit to somebody who doesn't mind harsh clutch.

Other option is one of the one disc extreme models from CM with sachs plate... cheaper but would it hold?

Still on the fence.

I don't really have time between work and car giving me issues (just replaced clutch and have coolant leak somewhere), but quick peaceful ride today showed that there is something wrong with mbar scaling of new sensor.

Basically ambient pressure doesn't match up to measured one when car is off/idling, off my almost 100mbar which with improper scaling would result in more mbar discrepancy as pressures go up.

Pressures match up to 1-2mbar pre-5120 changes.

Ok, I did some internet searching and info is hard to find but found this info on 4bar sensor 0281006060:

200mbar - 0.215V
3408mbar - 3.803V
4000mbar - 4.461V

Plugged both ranges into formula from page 352 and they both came out to 894mbar/V or 447mbar/V (vs 430 as calculated based on 2.5bar specific scaling info extrapolated to 4bar) when putting it into bin with 5120 hack in.

That's still doesn't account for my 80mbar difference at atmospheric pressure between two variables especially that they both are calculated using DSLGRAD and DSUOFS... something (missed in 5120 implementation) must be altering  pvdks_w

Post some logs please of pressures matching within 1-2 mbar.
Does not sound very likely, because the turbos are still producing a minuscule amount of boost, even on idle.
Depends on your dump valve set up too though.

Ok, 4-5mbar POSITIVE (looked at several idling logs), but not 80 negative as in logs posted above... but this is irrelevant to this discussion since the behavior you're bringing up would add to the MAP pressure... and since it does add a few mbar, the real gap is even wider.

So... any thoughts? Some minimums kicking in for MAP sensor maybe? I would log B_lde, z_lde (recalling names from memory, whatever they are called in the section calculating sensor pressure reading) and several other variables to narrow this down but have no location addresses.

Both psu_w and pvdks_w use DSLOFS in calculations and psu_w appears above 1000mbar for sunny weather I have here today. Again, the problem is that using the same translation table and offset, both variables have much different value when idling / at ambient pressure (plus few mbar as you pointed out) so something is changing/disregarding/correcting pvdks_w in its path probably due to some minimum we missed.

pus_w does NOT use DSLOFS. It uses DSUOFS/DSUGRAD.
Your DSLOFS is incorrectly defined, that is why your pressure is off.

Post by: phila_dot on February 20, 2013, 09:35:23 AM
psu_w?

udsl_w * DSLGRAD + DSLOFS, gets filtered to pvdksf_w, and compared to pvdkmx_w.
If pvdksf_w > pvdkmx_w then pvdks_w = pvdkmx_w and B_edsl is set.

Else, pvdks_w = pvdksf_w and B_edsl is cleared.

The only changes required in this path are DSLGRAD, DSLOFS, and PVDKMX.

The filter doesn't need to be touched.

PVDKMX shouldn't cause the symptoms that you're seeing.

That would explain it. I didn't catch this subtle difference when looking at PDF... so this is missing from 5120 XDF then.

Anyway, looking at your XDF from a while ago (auto generated), DSUOFS is zero... My DSLOFS is -4.10hpa (as per bin posted earlier). That's still only 4.1mbar difference between values so unless location of DSUOFS at 0x13DEE is not right...something else is at blame.

Please advise.

Edit: can this offset be as high as ~40-50mbar? If so, taking inaccuracy of DSLGRAD value, it can be made to work.
Edit2: NEver mind edit #1, changing DSLGRAD would keep the gap as wide anyway.
Edit3: just noticed that both variables don't share anything, DSUGRAD vs DSLGRAD got me too...

If your DSLGRAD is wrong, that can do it too.
You got the info online, but better would be to get this info from the EDC16 or EDC17 ECU where that sensor is mounted.

If you think that DSLOFS could be very small for this sensor, then it makes sense that your DSLGRAD is wrong.
Try adjusting your DSLGRAD so it's more in line at idle.

Really this is just a problem with the MAP sensor linearization in my opinion.

You're must be right. I will first address DSLGRAD to have actual proper value and see how much I am off. It has to be the offset afterwards. I was confused, yet again, and not noticing that the two varaibles I am comparing are using two completely tables . Dyslexia hits: DSLGRAD  vs DSUGRAD

General trend has been to take axis definitions and move them into the Axis Sub-Section.
Additionally:  DSLOFS, DSLGRAD, DSUOFS, DSUGRAD have been cross-checked and verified to be correct versus PRJ's auto-m-xdf.

I'll continue to update this as we find changes.
Our goal here is to get a completely simplified list to do the swap with little effort.

Summary:
DSLGRAD: 0x13DEC
DSLOFS:   0x13DEE
DSUGRAD: 0x1BE68
DSUOFS:   0x1BE6A

I solved the problem with leaning out while taking off some throttle, KFVAKL map was at fault, I reverted to stock one few weeks ago and it was a mistake and large injectors mine anyway) require it to be essentially zeroed out to not cause issues when transitioning to falling loads...

So cross that one off.

I also adjusted DSLGRAD so that both pressures are equal at engine stopped. I ended up using 461 hpa/V for DSLGRAD and 3.91 hpa (positive) for DSLOFS.

Here are my theoretical calculations per data found on internet and me 7.1 manual:

Sensor linearization:

200mbar - 0.215V
3408mbar - 3.803V
4000mbar - 4.461V




Stock example:

             delta y       (2500 hPa - 200 hPa)
DSLGRAD = ---------    ---> ----------------------    = 541 hPa/Volt
             delta x       (4.65 Volt - 0.4 Volt)


4bar MAP:

     4000 - 200
   -------------  = 894.95     ----> 5120 hack -----> / 2 = 447
   4.461 - 0.215
   
   
     3408 - 200
   -------------- = 894.09     ----> 5120 hack -----> / 2 = 447
   3.803 - 0.215
   


DSLOFS:

Stock Example:
   pvdkds = udsl(200hPa)*DSLGRAD + DSLOFS ---->  DSLOFS = pvdkds(0.4V) - udsl(200hPa) * DSLGRAD = 200 hPa - 0.4 V * 541 hPa/V = -16.4 hPa

4bar MAP:
   DSLOFS = 200 - (0.215v * 894 hpa/v) = 200 - 192.21 = 7.79     ----> 5120 hack -----> / 2 = 3.895



I was still off by some 20-30 mbar after this so I asdjusted DSLGRAD until the pressures matched, I didn't bother with properly scaling DSLOFS since it would only change by 1mbar if that, no point touching it. Sensor's measurement error is much higher than this.

Try with DSLGRAD 437.5 and DSLOFS 31.25

Can you elaborate why these values? If shooting in the dark, one can really adjust stuff randomly until it matches... I can tell right off the bat that it would probably no work anyway since it wouldn't make up for about 80mbar discrepancy I was experiencing when using 437 and -4mbar for offset...

I will be comparing actual boost level to zeitronix and manual gauge sometime near future to see if scaling value is ok. Not until my clutch breaks in though.

Anyway, who else is using the sensor? Am I the only one, lol?...

I use the same sensor as you for my drag car. At first I had the same problem , I searched linearization of the sensor but I have not found it. Another 4 bar sensor which I've used very often but in diesel cars with BT is 0 281 002 316 and for this linearisation is: 500mbar at 0.5V and 4000mbar at 4.5V. This calibration we used to my car and the result is satisfactory.

Why not test the sensor and record actual pressure vs voltage?

Cool. I will give it a try. A long time ago I found specs for map sensors on bosch site and the one you listed struck me as a fit for our cars:

http://rb-aa.bosch.com/boaasocs/index.jsp;jsessionid=A33AAEE16429B168F3E582158D1DE99D.sundoro?ccat_id=110&prod_id=203

It makes sense that they would use common chip for measuring pressure (motorola freescale?) and only stuff it into different part# for specific applications.

Coincidentally, that sensor looks like a better fit for our cars since it is a 'fat' inlet from factory?

03K906051? I am using that sensor :)

I dont get what is the problem? You have to enter hPa/voltage, its just a single constant and you have the ambient pressure sensor for reference.

Compare vs pu_w, if it doesnt match up, just pu_w / pvdkds_w and apply the factor to current DSLGRAD.

When it matches, back calculate the linearization point values using the FR formula and then re-calculate DSLOFS.

Roger... but I wanted them to match up after using specs not working them backwards from differences between pressures. Sounds like the official specs for different part# 4 bar MAP should work 100% accurately and I will check that in couple of hours.

Yeah I understand, FWIW I had a 5.4% difference from the spec you posted.

IIRC britishturbo also had have like 6% diff from the FR calculated value on his homebrew sensor.

Ok, confirmed. 437.5 and 31.25 (thanks to 99pwr for pointing me towards this direction!) which are calculated values for bosch 0 281 002 316 are spot on for this one. My pressure differential with engine off is 2mbar, that's 0.2% discrepancy and essentially dead on within reason considering there are two separate sensors measuring these...

DSLGRAD = (4000-500) / (4.5-0.5) = 3500/4 = 875  ---- 5120 hack ----> / 2 = 437.5
DSLOFS = (500) - (0.5 * 875) = 500 - 437.5 = 62.5  --- 5120 hack ----> / 2 = 31.25

Let's talk PID control.

Am I right that the PID control will be all messed up with the 5120 hack? Seems like KFLDRQ2 axis is changed (most important one) but there are other parameters and they all have output in %/hpa. Since we are halving hpa change by half, shouldn't the tables be multiplied by two then?

List:

LDRQ0S
LDRQ0DY
LDRQ1ST
LDRQ1DY
KFLDRQ2 (done?)

Without Q0 and Q1 changes, the PID will have hell of a time (or fail altogether) in keeping desired boost.

Percentage doesn't change.

500mbar is 90% of 550mbar the same as 1000 is 90% of 1100mbar.

500mbar is 90% of 550mbar the same as 1000 is 90% of 1100mbar.

I did a quote from ME manual which was an excerpt and out of context really. The outputs from tables/scalars for PID control are converted "change from %/100hPa to %/hPa" (divide by 100) with a footnote that the part I copied "%/hPa", should really read "% / 1hPa".

As such, they are unit of pressure dependent. When ECU is reading 50hpa difference and tries to match it, it calculates change in DC for 1/2 of what it should be using which is 100hpa. Hence the quotients should be multiplied by two, I assume unless I am not thinking straight (keep in mind I don't really know how this is all calculated so don't blast me!)

Anyway, my empirical preliminary pulls indicate that PID controller is unable to control boost on my 770s, once it overshoots it never pulls out enough DC to even stop boost increase. It might be my completely inadequete KFLDRL which I need to still calibrate, but I suspect PID controller is out of balance as far as dynamic control goes as well as the quotients are not scaled to reflect 5120 change (well, one is but the others are not).

Im 99.9% sure julex is right, altough it looks a bit different in my binary as all my dynamic q0/q1/q2 are KF's, they all have the lde axis which I have documentend and scaled 50%.

But, the static q0/q1 I have indeed overlooked and should be increased by 100% as the input is halfed with this hack :)

My reading of the FR (and the Q0/Q1/Q2) tables tells me that they all need to be scaled - for maps with lde, plsol, etc as input, those axis, for scalars their values have to be scaled (since they directly multiply lde).

Glad to see you guys making further progress on this!
I've been super busy lately and haven't had a chance to post on here... Looking forward to getting my 3,0 build done so I can carry on working on this!

As far as sensor calibration the way I dialed in my slopes was as follows:

Stock MAP Sensor + Stock Code: Record MAP Sensor pressure in VagCom with Engine off
Flash
Stock MAP Sensor + 5120 Code:  Confirm MAP Sensor pressure in VagCom
Flash
400kpa MAP Sensor + 5120 Code: Record MAP Sensor pressure in VagCom (Calculated values for MAP sensor)
Scale hpa/v as needed to get MAP reading ambient correctly
Flash
Check MAP Sensor pressure in VagCom - Do a happy dance

Small setback... while calibrating my KFLDRL @ 60 WGDC, my TBB popped off the throttle body @ 34psi of pressure and took out my shiny new 4bar MAP sensor... The neck cleanly sheared off the main sensor body since I had it on a bracket...

Note to everyone: Don't use factory bracket with high boost application and aftermarket bi-pipes without mounting tabs that fasten them to TB covers...

Damn that really sucks... I'm glad with the single setup I won't have to worry about that given I use a pipe with a welded on flange.
If you want I can send you my ghetto 4 bar sensor to use while you wait for a new one, I was going to just get a new one anyway.
PM me your addy if you want it.

Thanks for offer but no rush. Even though it ripped itself out, I can move it around to touch TBB and therefore not have gaping hole in there. So long I don't boost the engine (it goers rich), it works fine without any codes.

I'll have a look at it tonight, I have a few old 2.5bar ones, I will see about transplanting internals to old sensor body. It will also give me a good look at what's inside :)

i know that you guys already accepted this, but I took a look at lditv_w and Julex is right.

I haven't done this part of LDRPID yet in my 5120 travels, but I'm going to just finish the function since I'm already in there.

Edit: Since leaving home, I decided that I should've said my initial interpretation is that Julex is correct. I want to take another look when I get home before confirming 100%.

100% confirmed Julex is correct.

lditv_w in my 5120 file with lde of 10mbar (original ME7L scale) and ldrki_w of 0.6 is identical to original M box with lde of 20mbar and ldrki_w of 0.3.

Sorry, I just like to be thorough.

Same with ELDOB in LDOB.

3.98 pressure ratio or ~ 43psi... somehow I don't think it will be a problem for anybody but a guy or two but then they can just underscale the maf by a little and that's it.

Dunno how similar my 018CH file is to your 032, but I'm about 75% done with identifying all the maps in Bische's text file. I'll upload the map pack when I'm done.

How are you trying to identify them? I used a combo of Bische's .bin and the fully defined TT225 ols. I was able to find all of the maps/constants except in the modules LDRPID, LDUVST, and RKTI. Most of the maps in those 3 sections are already defined though, that was just the point where I stopped.

PS. Many thanks to all who are involved in this project.

That looks like a pretty complete list. What are you missing? The pressure constants?


Im sorry but can you show me an example for pressure constant?
Pressure Constant is the 10mbar Constant?
Im not sure this will working or not, i cannot test it now.
But if i get it tested anywhere i do ols file and upload it :)

So I've received my MAP sensor and I've installed it but the rubber reducer does not really go well
with the rubber/silicone TBB. I was not able to get it in there properly. I've tried different types of

How did you guys install this properly?

I would guess that there is zero risk that boost would make it pop out. The diameter is too small. You cannot compare large pipes and this.

I looked at it today again and it seems to me that the real issue was that the hole is not cut straight on the TBB so the clamp actually helped pushing the damn thing out because the reducer gasket's height is quiet small. I will try to use a single ear hose clamp because the that is way smaller than a regular clamp and if that does not work, well I will try to make an aluminum adapter.

I am having problems controlling part throttle angle causing overboost on big turbo (this is without WG activity). Essentially the ECU is overestimating how much throttle to use to reach needed boost level and it overshoots the target by a lot.

It is clear to me that something in FUEDK (throttle control) is awry so I looked at diagrams and I think I found missed "1013" constant:

(https://lh3.googleusercontent.com/-k2UDoNdjZ34/Ub8gQllSYDI/AAAAAAAAKfU/SNhUlVhGIO4/w1167-h801-no/FUEDK_UMPSPI.GIF)

At least I don't see it in list posted in original post and as I don't have a tuning laptop with me, I have no convenient access to XDFs etc that we have for 5120 hack.

I have 20ish WG spring too.

I will post logs later this week. Are you telling me that when you step on it 50-60% torque (engine would need say 10psi of boost to fulfill the request), the car boosts up without overshot far over 10psi? Mine is shooting over to 17-18 and it takes it time to modulate throttle and lower boost to whatever value it needs to be for a given torque request.

Anybody has pre 5120 hack log showing PSSOL_W values?

What are they showing at idle/low load, is it at/over 1000mbar or does it is below 1000mbar anywhere?

I am still having weird issues with part throttle where car goes into palpitations mode and the pssol_w sticks out having values under 1000mbar, it is about 370-400mbar at idle and 700-800 in the area where engine starts jerking at around 0-1psi where the  pvdks_w shows positive small pressure at throttle.  In ME7 logger, I have the conversion set to x 0.0781250 like any other 5120 hack pressure variables from stock x 0.0390625.

I don't think it is me7 logger conversion though as during high-part and WOT the pressures more or less match.

I am just wondering, provided the logger shows true value of pssol_w, if there is something missing in 5120 changes that screws up pssol_w and confuses the hell out of the car.

Thanks in advance for suggestions.

pssol_w is requested manifold pressure.

Im going to give some hints as I havent seen this up for discussion yet: Put KISRM back to stock, it has nothing to do with scaling ps_w, it is just an integrator. It is there to tune the response of ps_w vs. airflow.

All scaling to ps_w is done in KFURL, both down and back up. KFURL along with KFPRG is imo the two most important maps as they are stating the engines VE for the fueling, throttle control and boost control.

KISRM is used to calculate fvisrm_w which then is used as multiplier to obtain ps_w so I think that not scaling KISRM will make ps_w completely off, 2x as large as it should be?

The answer is right there in your first pic, it is an recursion where rlroh_w is always subtracted by rl_w and turns the KISRM mulu into its role as an integrator.

The KFURL/KFPRG calcs is by far the most brainmelting section to get a grasp of.

Wrong. Look at the algorithm.

So in your opinion, which variable do you change to scale ps_w?

There is a 1013 multiplication in fvisrm_w, but whether you scale this multiplication OR you scale KISRM makes no difference per algorithm.


Title: Re: The 5120 hack - Running up to 5bar absolute pressure on ME7.x
Post by: julex on July 19, 2013, 12:27:08 PM
On a side note:

I noticed that supplied converted value of KISRM was wrong due to not enough decimal points defined in XDF and tuner pro rounding up stuff based on number of decimal places displayed (lol on that one...). Original M-box 0.122513, bin 0.059998, should be 0.061249 (closest to prefect value). The difference was 2%, not a huge one but it was there.

I am still awaiting the outcome of KISRM discussion though.

KFURL with the offset of KFPRG. The mulu in fvisrm_w is 10.13, which saves 2 decimals in the final compution/sync, likely to stay inside 8bit limitation and/or give more granularity to KISRM.

Except that KFURL has no effect whatsoever on ps_w and KFPRG is just an addition, which is added AFTER ps_w gets calculated.

So, what do you modify to scale ps_w?

Also, KISRM is 16 bit, and ftsr is movbz'd to a word anyway. So the KISRM by ftsr mult is also 16 bit, and the 10.13 mult is 16 bit as well.
No, you are not gaining any useful precision whatsoever.

Yes it does really put the shape on ps_w, it is the map to tune ps_w(and requested, pssol_w). As I said, this algo is really hard to get a grasp of, but once you do youll be saying "oh shit" to yourself. Just make a 10% change to cell affecting idle and slap it your RS4 and tell me what results it had.

I know KISRM and ftsr is words, but you need to look further. Where actual load rl_w is extracted, it is also calculated in 8bit as rl which is our imfamous big game variable.

my impression was that the primary purpose of the (eponymous) 5120 hack is NOT precision, but to overcome the 2059mbar limit.

To that end, i thought the purpose of this subthead is to discuss to halve both ps_w and pssol_w properly, and not so much worrying about the precision of the 8 bit rl..

Or am I missing something obvious?

No youre right, it has no meaning to discuss the precision, I just accidently sidetracked this a bit with prj.

My meaning was to say why the fvisrm_w is calculated with 10.13 instead of the regular 1013, is to put less strain in the algorithm. If you look further at the calculation of ps_w it is crystal clear, there are further computions.  

You could have 1013 there instead of 10.13 and it would work anyway, youll just end up with two decimals higher values in KFURL/PRG and there is where more important precision would be lost.

Look, once again. KFURL has no effect on ps_w whatsoever. How about you actually disassemble the code and look.
Only thing KFURL really affects is how much boost the ECU will request to reach a certain req. load (yes I know it is used for other things as well).

I don't need to "slap" anything anywhere, I change this map all the time on non-standard setups.

More fuel for thought.

The pull below is 2nd gear one which resulted in leaning out up top drastically due to PS_W dropping inexplicably at normal maf flow and boost level readouts. PS_W drops in 0.1s from 3320 to 2673 (and so does engine load), that's 20% drop all of the sudden. My Zeitronix AFR ("WB_AFR_b1" or "WB_Lambda_b1") reports corresponding increase in AFR as the PS_W dips and interestingly, msdk_w (air flow over throttle) bumps up at the same cell by 1.6x from previous one.

This is with newly reset KISRM to stock value. I didn't see that in previous logs with halved KISRM.

It seems like PS_W calculation is fubarred now with stock KISRM given that everything else seems normal for a pull... how is everyone else with stock KISRM?

Looks like a cam changeover point to me(just like it switches at 4500rpms), the change in ps_w just much more abrupt now with double the KISRM(assuming you went from halfed stock KISRM, back to stock).

Doesn't it? Except that I don't see MAF flow change which usually is a result of switching cams off (you can see a notch) and that my changeover is at 4k. I will log the same with KISRM halved next to ensure I have no other issues.

Sat down and looked through all the code, as the docs really do not state clearly how this actually works.

ps_w at startup is initialized to pu_w.
After that ps_w is never completely re-assigned. Basically what happens is, delta manifold pressure is calculated and then added to ps_w.

It subtracts rl_w from rlroh_w to get the delta between current load and load from MAF and this delta is multiplied by fvisrm_w, which is (KISRM * ftsr).
If it is not zero, it is either added or subtracted from ps_w, and we get the new ps_w value. Basically fvisrm_w is conversion from load into pressure (opposite of KFURL).

After that ps_w is converted to load via KFURL, however KFURL itself does not affect ps_w directly.

So what happens if you do not halve KISRM nor the 10.13 calculation?
Your delta pressure is evaluated to double, and the filling models in the ECU start fighting each other.
I looked at this a long time ago, and came to the conclusion that KISRM or the 10.13 must be halved. Looked at this again now with a fresh start, and came to exact the same conclusion.

If it is not zero, it is either added or subtracted from ps_w, and we get the new ps_w value. Basically fvisrm_w is conversion from load into pressure (opposite of KFURL).

After that ps_w is converted to load via KFURL, however KFURL itself does not affect ps_w directly.

I saw the same.

So what happens if you do not halve KISRM nor the 10.13 calculation?
Your delta pressure is evaluated to double, and the filling models in the ECU start fighting each other.
I looked at this a long time ago, and came to the conclusion that KISRM or the 10.13 must be halved. Looked at this again now with a fresh start, and came to exact the same conclusion.

This does make sense.

Thank you, now with your new understanding we can discuss how this works :)

Sat down and looked through all the code, as the docs really do not state clearly how this actually works.

ps_w at startup is initialized to pu_w.
After that ps_w is never completely re-assigned. Basically what happens is, delta manifold pressure is calculated and then added to ps_w.

It subtracts rl_w from rlroh_w to get the delta between current load and load from MAF and this delta is multiplied by fvisrm_w, which is (KISRM * ftsr).
If it is not zero, it is either added or subtracted from ps_w, and we get the new ps_w value. Basically fvisrm_w is conversion from load into pressure (opposite of KFURL).

No, it is not a conversion and not the opposite of KFURL. It is an Integrator (KISRM = Konstant Integrator saugrohrmodel), and one thing that the FR actually states in all this, is KISRM's function.

It also states how to turn the function off(KISRM = 1), if KISRM really was where we scaled ps_w this would net you a modeled intake pressure of 20-30bar lol. Julex log also prooves this, he doubled his KISRM but he didnt end up with a ps_w of 6000hPa.

KISRM is there to tune the response of ps_w, just like any other I part.

After that ps_w is converted to load via KFURL, however KFURL itself does not affect ps_w directly.

I agree, KFURL controls ps_w indirectly(with offset of KFPRG).

So what happens if you do not halve KISRM nor the 10.13 calculation?

The fvisrm_w mulu is applied to the load delta before we scale down ps_w.

Edit: I have to get back on that one tbh

FVISRM is. More rather the 10.13 multiplied into it is.

Of course he would not, as ps_w is INITIALIZED to pu_w, and after that delta pressure is used.
Not changing KISRM or the 10.13 is like telling the model that it's intake manifold is double the size. That's why his ps_w is too high for the boost, and why it oscillates.

So youre still holding on to this?

Except that KFURL has no effect whatsoever on ps_w and KFPRG is just an addition, which is added AFTER ps_w gets calculated.

So, what do you modify to scale ps_w?

Post by: prj on July 23, 2013, 04:43:59 AM
I don't see what is so hard to understand.
fvisrm_w converts delta load (rlroh_w - rl_w) to delta pressure (dpsfg_w). It consists of 10.13, KISRM and ftsr.
They are all multiplied by each other so whether you scale the 10.13 value, KISRM or ftsr does not matter. ftsr is used in a few other places. KISRM and the 10.13 are used in just one place. KISRM is a normal parameter, 10.13 you have to find and half in the code - KISRM is easier to change.

ps_w is not directly scaled by KFURL, ps_w is scaled by DSUOFS and DSUGRAD and then the 10.13 constant or KISRM, which govern it's rate of change.

The docs do not fully explain how this works, period. I also do not see why you expect ps_w to be double with double KISRM.

Hiccups are still there with halved KISRM. I am getting mysterious PS_W drop with associated RL_W and fueling going awry per my wideband O2 although ECU things everything is ok, of course. NWS switchover is at 4k and I see associated activity so I don't think this is the culprit, but here is the KFURL as requested.

Please look at my log, row 88 and 89. PS_W drops again and so does RL_W... I will welcome any suggestions.

Edit: I will log pvdkds_w to see if I am not hitting psmx_w (I don't have memory address for psmx_w, but pvdkds_w will suffice) and therefore limit the ps_w.

*FACEPALM*

Mystery solved... my KFMLDMX table was not adjusted from old stock sized intake tract and now with all RS4 or larger stuff my MAF is hitting new heights. I hit and exceeded flow threshold in this table. ECU switched to normalized flow and hence the fueling going off. Obviously I need to massage the tables for MAFless path, at least put them on the rich side so that engine doesn't blow up when maf readings are off.

Curiously enough, I remember getting beeps and check engine light combined with limp mode when I had this happening previously and I am not sure why this time around this didn't happen... maybe there is a certain threshold you need to go over to get that (too lazy to follow FR on this).

This issue is solved then.

Does anyone know if the limit for KFLDHBN is 4 bar?
I think I've run into the limit of requested boost pressure ratio again.
The stock setting was 3 bar which I raised to 4, but now I'm requesting 4 bar and the max value it will take in TunerPro is 3.9844, which is FF in hex of course...

So this is a slight problem lol. Can we internally scale KFLDHBN?

And yes I'm really running up to and including 40psi on the street - which seems to be the limit of requested boost I can get lol.

Incorrect the KFLDHBN is still limited to a pressure ratio of 4.
So even with a 5 bar requested boost will not go above 4... that's my problem lol.

I figured as much. 58.8psi is not an insignificant figure. I think to cross that threshold reliably we'll be taking about beryillium pistons, F1 inspired rods and a titanium crank.

The one posted in this thread, M-box and XDF is basically complete sans KISRM being inaccurate and possibly couple other items. Just double check that if it needs to be halved, it is, and is not rounded up/down by tunerpro.

There's actually tons of stuff missed that is not in any publicly posted XDF.
But after what is going on there, at least I do not have any motivation to post anything related to this.

Did I miss soothing?

I plowed through PRJ's XDF and identified all the maps that use hpa on their axis (not to say that there aren't more without explicit units on them) and double checked vs xdf posted in this thread... one item stood out which is SDLDSUA which controls N249 activation thnresholds... There are a bunch of other maps, dealing with I-pid adaptation thresholds and leak detections which are not that hugely important.

I am currently at a point where I have my tune pretty much worked out but part throttle turbo surge (cha, cha, cha, cha) and associated boost fluctuations are killing me and until today I was not sure how to cure it until I reviewed the XDF. SDLDSUA is directly responsible for activating N249 at certain predicted boost thresholds and I hope it will cure it albeit I am sure that the source of my problem is over-boosting at part throttle which induces throttle cut and turbo entering flutter mode.

Interesting. I don't use the N249 and neither do most people I speak of... could be it.
But I do know that part throttle is very good on my setup. I've had people complain about certain others part throttle driving, have changed them over to my KFMIRL and KFMIOP and they have been super happy campers.

The only time I know I've seen N249 problems was when I flashed someone a tune with the N249 coded out and he still had it lol, that acted like you describe. But a change in settings and he was good to go again.

You can always log B_ldsua to confirm.

IIRC, the was a code change or two in LDUVST.

Like prj said, there's a ton of changes that haven't been documented. I'm finally setting up a new laptop now and will be starting to work on this again shortly. However, I alot of my free time will be spent wrenching on my latest S4.

Yes, I logged b_ldsua earlier today along with cells migration and values change (SDLDSUA doesn't have axis per se, it is hardcoded so you need to shift cells first into 1/2 pressure slots on the axis  and then lower the cell values themselves  by 1/2) and oh boy.... now we are talking. Basically, anybody deleting N249 is super retarded, no offense, as they REALLY don't know what they're doing.

In my case, N249 is activated via b_ldsua up to about 60 load (no scaling) and the engine got super snappy in part throttle while before, with deleted N249 or with it in place but table messed up, the car would basically be falling on its face in part throttle in vicinity of -8inhg to 0ish-1psi. It makes sense that opening the DVs with vacuum reserve allows to free flow of air in NA engine fashion and turbos don't have to work and kill engine efficiency.

On the other side of scale, i've seen mega spikes of pressure and super loud surge sound when coming out of WOT @ 32psi with N249 delete, the pressure at sensor would spike to 40psi.

DO NOT DELETE N249... you will sacrifice part throttle economy and response as well as basically risk catastrophic failure of turbo due to surge.

Totally agree, I originally deleted and then later added it back in and much better part throttle and lifting off at the end of a WOT run with n249 back in place.

You know I might just put the N249 back on the car to see how it runs that way... just as a test, but I don't have any of the problems you describe.

New turbo comes tomorrow though, 6466, should have a lot more boost down low and at part throttle.

I don't claim to be an expert... And I've never actually ran my car with an N249... it was removed when first setting up my single turbo setup, probably for all the wrong reasons considering when I took it off I didn't know exactly how it worked and was following the general trend...
So I'm actually in the process of putting the N249 back on the car for some back to back testing.

FWIW, I re-installed my n249 on my BT 1.8 and noticed less compressor noise off the throttle. I too went with the crowd and deleted my n249 early on.

 I second that. I had a very clear spool up noise from turbos in sub 0psi in part throttle which is gone now with N249 in place and allowing the engine to breathe. The noise was indicative of energy wasted to unnecessarily spool turbos with the intake air.

Simple define once and then turn on and off with a button.

Sorry if I missed an answer to this in this 30 page thread....

The sensor part number referenced a few times is "03K 906 051."  Where are you guys buying this?  Only places i can find it appear to be in the UK?  Is there another, more readily available sensor?  I don't really need to do this modification, but I think my map sensor is acting up, and I figure this modification is only going to open up my options in the future.

yup, got mine from UK. They are fast shippers and it only takes a few days. They even included the grommet for free when I messaged them about it but in retrospect I would definitely use something else in its place. A piece of some hard plastic tube or something. The supplied grommet tends to get squeezed out along with the sensor if you clamp it tight in the boot.

Yes you do, however as julex said the reducer is made out of rubber so you might have issues if you are using a rubber/silicone TBB. This is not an issue of course if you have an APR bi-pipe or an RS4 one. You can also make a reducer out of aluminium so that you can properly mount the sensor. On my old car i've been using a 034 motorsport TBB and I just used a zip tie to mount it because I could not fit a clamp properly, it never popped out.

Title: MSDK_W shows 1/2 of what it should be showing with 5120 hack
Post by: julex on March 11, 2014, 10:55:57 AM
I am trying to figure out why MSDK_W (flow over throttle plate) is roughly 1/2 of actual maf flow.

I followed ME7.1 bible and it appears that BGMSZS. bgmszs-lad function, fpvdkds_w * fkmsdk_w calculation is at fault here since the fpvdkds_w is 1/2 scale and is used directly in further multiplication with msdkue_w to give msdk_w... KLAF table output multiplier shouldn't affect this much although input to it is also 1/2 of what it should be.

Anybody has any idea for quick fix to this?

Hey guys,

I collected some data for both my 5 bar AEM "brass" MAP sensor and my AEM 5 bar "Stainless steel" pressure sensor. The brass sensor is being logged via  ME7Logger with a DSLGARD = 646 and a DSLOFS = -323 per my calculations. The stainless steel sensor was being logged via my Zeitronix datalogger (both sensors logged during the same run at the same time).

You can see that the sensors track each other quite nicely (my offset is off about 2psi with my DSLOFS calc) and the brass sensor is a little bit noiser (too be expected).


EDIT: Correction, looks like I had a typo and my offset was actually -330 instead of what it should have been (-323). I will correct this and see if this corrects my offset error.

EDIT2: So it turns out I was wrong here. I replaced the brass sensor with the SS version and my boost curves now fall right on top of one another. DO NOT USE THE BRASS SENSOR IF YOU WANT ACCURATE READINGS!


Title: Re: The 5120 hack - Running up to 5bar absolute pressure on ME7.x
Post by: jmont23 on March 21, 2014, 06:59:17 AM
I believe the reason for the 2 psi offset is due to the brass sensor being about 2 feet away from the throttle body where as the SS sensor is reading off my intake manifold.

They should read the same if placed in the same location, if one is in manifold and the other somewhere else, then it is natural to have some discrepancy due to pressure losses etc.

I have installed map sensor from diesel and it works perfect. But now I would like to increase boost to 1.7 bar and I think I changed everything (pvdk_w etc) into my file, but idle is unstable and the engine doesnt work correctly (reduced power etc). Its R-box ME7.1.1 and its a little differ from M-box ME7.1
Please help if you know how to make it work.
I would like to install garrett 28 in near future and without this hack its senseless as you understand.

It sounds like you may have missed one or more of the 1013 mbar constants. I missed one at first and experienced the same thing you are.
When you say ME7.1.1 R-box, do you mean for the 2.7T (4Z7907551R)?
If so, here's the locations for the 1013 constants I changed & I've got the 5120 hack running w/ no problems for quite a while now. Also double/triple check that you didn't miss any other table or axis on the list in this thread.
0x6D8EC
0x6D8F2

I actually don't have a stock file with only the 5120 changes done, I made all the changes to a copy of my tune at the time.  I've been meaning to put a stock 5120 file together to put up here but just haven't gotten around to it.

Ive just tested it and idle idle is ok, AFR is ok also, but
requested boost = 1250 mbar (2500 mbar without 5120)
actual boost = 770 mbar (1540 mbar)

I think I missied some PID axes or smth like that. And I cant find DPVLMS in ME7.1.1

Not to rehash the KISRM vs 10.13 scaling, but does anyone see #999h or #510Ah as the hard coded 10.13 ? If so, how does that equate to 10.13 with any of the hPa map factors?


Code:
mov     r4, #510Ah
extp    #0E1h, #1 ; 'ß'
movbz   r5, ftsr_byte_384865
shl     r5, #8
mulu    r5, r4
mov     r9, word_FE0E
add     r9, r9
mov     r9, word_FE0C
addc    r9, r9
jmpr    cc_NC, loc_866918

mov     r9, #0FFFFh

loc_866918:
mulu    r9, r7 ;KISRM
mov     r4, word_FE0C
extp    #0E1h, #1 ; 'ß'
mov     fvisrm_w_word_384AA8, r4
mov     r5, #999h
mulu    r4, r5
mov     r5, word_FE0C
mov     r4, word_FE0E
mov     r2, r5
shr     r4, #11
shr     r5, #11
shl     r2, #5
or      r4, r2
mov     fvisrm_w_word_381E66, r4

Seems fvisrm_w is defined once (384AA8) for use in BGRPL and then multiplied by #999h (381E66) for use inside BGSRM. DOC doesn't state this. Or I've incorrectly identified the variables.

Still not having fun.

Here's the 4Z7907551R file with the 5120 hack, It's still set up for the stock 2.5 bar MAP sensor. The xdf is a bit disorganized (I moved a lot of the maps that I was tuning into the top category so I could see them easier) but it will display the correct hpa values in all the maps that were changed.

It exists in the fully defined TT225 file I have, but I can't find it in my file or the fully defined S4 file I have. Daz has given me some info that it doesn't exist in a 518 file he has, so I am at a loss.

Can anyone confirm if it exists in my 018CH, or if it is not used in my file? TIA

Post by: catbed on June 07, 2014, 10:58:05 AM
Went back and looked at the file some more. It seems SDLDSUA is the 16x1 map that needs division in the 018CH file. Both the axis and table are in hPa.

Although the axis does not reference eprom, it's only 1,2,3... with a conversion factor. I am assuming the axis is boost pressure, so that should already be scaled?

EDIT: source for SDLDSUA axis is plsol

Another EDIT: This is from this very thread :facepalm:
...(SDLDSUA doesn't have axis per se, it is hardcoded so you need to shift cells first into 1/2 pressure slots on the axis  and then lower the cell values themselves  by 1/2)...

Julex, I'm not quite sure what you mean by that. Care to shed some light?

Ok, so here is my 018CH 5120 files. ASM divisions are correct.

It drives fine and boost is controlled the same as my non-5120 file, but the only problem is idle. When I blip the throttle at idle, the engine stumbles because it goes way rich. te_w goes up to like ~6ms. Any ideas what I could investigate?

I am working on completing the 551M 2.7t 5120 bin (based on britishturbo's bins posted in the 2nd post of this thread), and there are a few remaining issues

If you have previously downloaded these files, please verify all of these changes in your file; there are many old/bad files floating around.

* LDRQ1DY is incorrectly doubled twice in most of the map

* PSSOLNGRD, PSSOLPGRD, LDEIAP, and LDEIAU appear to be scaled wrong (incorrect sign handling):

StockBTProposed
NGRD:0x8AD0 (-30000)0x4568 (17768)0xC568 (-15000)
PGRD:0x7530 (30000)0x7518 (29976)0x3A98 (15000)
LDEIAP:0xFE (-2)0x7F (127)0xFF (-1)
LDEIAU:0xF6 (-10)0x7B (123)0xFB (-5)

* SDLDSUA is stock in britishturbo's files:

The maps regarding the DV operation I have not scaled, I did spend an amount of time to find those stubborn bastards and had some resistance, so I moved on through the list.

Yes, I logged b_ldsua earlier today along with cells migration and values change (SDLDSUA doesn't have axis per se, it is hardcoded so you need to shift cells first into 1/2 pressure slots on the axis  and then lower the cell values themselves  by 1/2) and oh boy.... now we are talking.

Yep, the axis is def hard coded, so the values have to be modified AND moved around some...

* UMDYLDR, DLUL, and EDLDRP are stock in britishturbo's files:

UMDYLDR - Divide by 2
DLUL - Divide by 2
EDLDRP - Divide by 2

Note that these are all tiny (0x02 hex or 20 hPa) so making them 10 hPa isn't probably that important

* FHOKH - minimum altitude factor for cat heating

What is up with this? It isn't a pressure value. In britishturbo's files, it isn't even halved... it's just set to zero. And what about the rest of the FHOs?

FHODSL - SAI?
FHODTEA - Tank ventilation
FHOE - "substitute value for altitude?"
FHOKOB - AC compressor?

* Brake booster:

I have taken a look at this list, there is alot of maps from the brake amplifier module %GGPBKV, if those need scaling or not is different between applications. You will have to check in your binary if this module is use to determine if scaling is needed --> http://nefariousmotorsports.com/forum/index.php?topic=3027.msg29820#msg29820 (http://nefariousmotorsports.com/forum/index.php?topic=3027.msg29820#msg29820)

CWGGPBKV - codeword to disable (stock is 6, which is disable)

OR if it isn't 6:

Trace and fixup:

PBKVVSTGPV
DPBKVEVKSP
DPBKVEVKEP - Pressure gradient factor
FBKVP - Factor for calculating min pump pressure

etc? I assume if we leave it stock (6) we don't have to do anything?

* Evap:

Quote
I also did trace the pus_w(PUSMAX/MIN in nyet's .csv), it is used for EVAP Leak detection pump, it goes like this:

pus_w -> %BGPUK (to determine if ambient pressure is sane), out comes pukor_w and pukorv_w -> %DLDP, which is diagnosis for LDP.

My file does not diagnose LDP (CDLDP = 0), so I did not follow up what impact the scaled pus_w would have. But if one have %DLDP active, you might want to follow it up :)

CDLDP is 1 in the 551M, so PUSPSMX seems it might need scaling too, although leaving stock so it is 2x bigger than it should be probably can't hurt, it will just numb the detection some.

* ZDSU:

ZDSU is a time constant, not a pressure variable. In theory, with pressure readings halved, the noise should be half as much, so probably a lower time constant would work.

http://nefariousmotorsports.com/forum/index.php?topic=13364.msg122164#msg122164

* pus_w:

Two more divisions, one at 0x5193E another at 0x51978, 16 bit, change 0x0287 (647) to 0x050E (1294)

Any comments? Once I clean these issues up I will update the 551M post below the OP

* VCDS OBD2 pressure logging:

The SDLDSUA axis isn't hard coded, it doesn't exist.

In the code the base address of SDLDSUA is offset by plsol ashr  4h.

All you need to do is rescale the axis in 320 mbar increments, change the table factor, and fill/extrapolate the values.

Interesting! Since we don't actually need SDLDSUA to be full range, can't we change that to ashr 3h and a compare (to cap it)? Then you only need to cut the data in half.

Assuming that your boost target is around the MAP limit or that you were just going to replicate the last value above 2560 mbar?

Yes.

The offset is already capped at 16 members in the code with a compare.

The code is located at 0x6EDF4 in both versions of M box. Change BC 4F to BC 3F if you want to go that route.

Bit off topic, but would numbing the PID let you go over the highest mbar of boost the pressure can see without the ECU stepping in?  How would it be done?  Going to be looking at running over 22.5psi on the k04-064 when its fitted on stock sensor.

Past the MAP, your req should be equal to the actual (if you zeroed DSLOFS like you were told to in the Tuning wiki), so the PID should do nothing.

If you don't zero DSLOFS, the MAP limit is below the max req boost, which means the PID will constantly add WGDC. Bad juju. If you are going this route, disable positive I adaptation, and limit DC via the LDRL map.

Note that using a 5120 file with req boost past the MAP limit is also a BAD idea, for the same reason. No amount of DSLOFS fiddling will avoid it. NEVER REQ MORE THAN THE MAX MAP! EVER! PERIOD!

Ideally, the 5120 files should be hacked with some additional assembly to cap the req boost according to DSLOFS/DSLGRAD (or adjustable scalar).

Don't do it unless you really know what you are doing (and read the above and FULLY understand it).... Get a 3 bar map and use a 5120 file.

What are you doing for the hard coded 10 hPa in LDRPID-MAIN for Hysteresis to set B_lddy ?

It's 8bit and hard coded #1. So, it can't be divided. Does that mean B_lddy is broken now? Or at least now considered 20 hPa (twice the left set value for Hysteresis)?

maybe 10 hPa diff in lde is nothing to worry about when setting (unsetting really) B_lddy.

in BGRLP-BPSPMV there is a division by 2.0. Should this division constant (2.0) be rescaled? This would affect psp_w .

Not an issue in S4 M box.

B_lddy is set if lde > 0 and less than UMDYLDR, clear otherwise.

Hmmm. I read the FR as b_lddy is set above UMDYLDR and cleared when lde falls below 10hPa.

10 vs 0 hPa I can see being different without deviating from FR. But B_lddy not being set above UMDYLDR on the M-box greatly differs from my FR understanding.

But I've never looked at the mbox. I'm wondering if changing the 10hPa to 0 would be better than leaving it at the rescaled 20hPa, to be more like the mbox.


Title: Re: The 5120 hack - Running up to 5bar absolute pressure on ME7.x
Post by: phila_dot on October 17, 2014, 09:17:31 PM
The factor is 10, so 1h is 10hpa.

Yes, you are correct. I wrote that too quickly.

B_lddy is clear if lde <= 0 and set if lde > UMDYLDR.

10 or 20 hpa hysteresis wont make a world difference for B_lddy, it is a ver small increase vs. what a sway in boost would make for performance.

Thanks everybody for the info you shared! Using posts in this thread + FR + IDA + 3 sleepless nignts I've successfully converted my 1.8T 032HN1 box to 5 bar.  First run at idle was impressive, I didn't expect much success from the first run. Night run on full load & full boost was amazing. Everything is under control. I observe no issues after conversion. Pressure sensor readings in logs were initially divided by 2, so I had to multiply by 2 corresponding me7log variables to compensate. From the logs I see that ps_w reading is correct, rl_w is also good and as expected, lamsoni_w shows proper numbers. It's cool to have more than 2.5 bar boost fully controllable. Increased my everyday boost to +1.65 bar & limited torque a little bit on 1-st and 2-nd gears, 3-rd gear now pulls very strong. But now with such pressure and +30C outside, my intake air is slightly hot (50-60C), so I will need to think about bigger intercooler.

* FHOKH - minimum altitude factor for cat heating
What is up with this? It isn't a pressure value. In britishturbo's files, it isn't even halved... it's just set to zero. And what about the rest of the FHOs?
FHODSL - SAI?
FHODTEA - Tank ventilation
FHOE - "substitute value for altitude?"
FHOKOB - AC compressor?
IMHO, there is no need to touch FHO* and other F (faktor) constants. Because unit of measurement for F* is usually pressure divided by some other pressure. Let's take FHOKH as example. In FR fho_w is compared with FHOKH. (If fho_w > FHOKH and B_hag then ... do something)
fho_w is calculated (roughly) as pu_w/1013
We already divided pu_w by 2 and divided 1013 by 2, so fho_w factor should stay the same after conversion... (1/2)/(1/2) = 1/1 ;)
Therefore no need to modify FHOKH and other FHO* constants.

Guys, which map sensors are you running to get 5bar of absolute pressure? :o

To me it looks like we can run either AEM universal 5bar map sensor or oem 4bar (0 281 006 060)?

BTW: what about 0 281 002 420?

I was thinking about this for a bit...
Did anyone try to cut everything in half and make diagnostic steps x2?
So it will read actual pressure over OBD?
If no one tried yet i'll take emulator and try to make it work.
Than you can run 4 bar MAP sensor and read 4000 mbar over obd without boost cap.

ME7Logger can scale the signals however you want.

Code:
#!/usr/bin/perl

use strict 'vars';

# use Getopt::Std;
use File::Basename;

foreach my $file (@ARGV) {
    open(ECU, '<', $file) || die ("Can't open $file");
    while(<ECU>) {
        my @line=split(',',$_);
        if ($line[5]=~m/{m[Bb]ar}/) {
            my $len = length($line[8]);
            $line[8]=sprintf("%*s", $len, $line[8]*2);

Ok, i'll try if i can figure it out than.
With diesels i do this all the time, obd protocol is 8bit so 255 steps and you tell steps to be bigger so not max out at 2601 mbar, but make it as high as you want (with lower resolution..)

which amounts to the same thing as the ME7L changes: i believe to get full range you'll have to tell VCDS that it is scaled differently, or you'll max out at 2550 again!

Hiya guys, I saw this thread bumped up the other day and it gave me a kick up the backside to finally give it a go.

Spent a full day on it yesterday (I've read it many times before though) and it works flawlessly so far! Just need to get a larger MAP sensor now (although annoyingly I had mine die on Saturday so had to buy a new 2.5 bar one then :( )

Big thanks to all who have put effort into this! For what it's worth, I've done it without asking any questions, although you need an understanding of it (i.e. it's not for lazy people looking for a quick fix) it's all there in the threads.

I spent some time trying to implement this hack to RS4  8D0907551F

I used nyet's xdf and I assume KFURL conversion factor is wrong, it was 0.000003 when it should be 0.0000025

I also created a table for KFLDRQ2 Axis that was missing

I could not find some maps/scalars:

DPVLMS
CWGGPBKV
PUEBKV

Not sure if these 2 scalars are correct, although I'm not sure if they need to be changed:

DPBKVEVKEP -> 0x1F932
FBKVP -> 0x1F93C

I did not test this yet, maybe sunday, but if someone could take a look and check if is ok...

I've tried to do this hack on S3 1.8t with 3 bar map sensor and on normal flash (2.5 bar map) with 3 bar map sensor I have actual boost 990mbar and desired boost 820mbar. On 5120 hack flash (Asembly 1013 changes and multiply and devide by 1.2) with 3 bar map sensor I have actual boost 820mbar and desired boost 700mbar.
I think it should go the other way.

Heres a log i took after installing the 4 bar map sensor with the values below.

When using 5120 XDF
DSLGRAD 875 DSLOFS 62.50

Baro pressure was 495 which is half what it should be. Actual boost is following the desired but theyre staggered. Im trying to determine whether my issue is with my 5120 file or just my me7logger .ecu file. I looked over the 551m .ecu file posted and did the same conversion adjustments of doubling the pressure variables. However in that .ecu file they did not double PU, PVDK, and PVDKDS values of 5 10 and 10. All the others conversion values are doubled around it from .0390625 to .0781250.
(http://i1312.photobucket.com/albums/t532/Cameron_Rayburn/ecuconversions_zpszzo3e5kb.png) (http://s1312.photobucket.com/user/Cameron_Rayburn/media/ecuconversions_zpszzo3e5kb.png.html)

Im running the 551r 5120 file posted on this thread. Also flashed a stock bin onto my car with the 4 bar map sensor dslofs and dslgrad and logged the proper amount of 995 mbar baro pressure. If i adjust the conversion value for PU (baro pressure) by X2 it should read correct right? It seems off that the .ecu file for me7logger on this thread would have that change if it were necessary.

So I tried to use the 551r hack file and transfer all of my relevant information from my Stg3 tune I am running. First time i used my previous .xdf and the 5120bin. I forgot that the bin ws already scaled and made changes to those maps. Car ran smooth but would Not go past 5psi if I was lucky.   

Re-tuned: I used the 5120.xdf, fresh 551r.bin hack and Only made the changes to (kfzw,temin,kfmirl,iop,ldr, ect,ect)  load, fuel, timing, injectors, and deleting my egts . This time the car ran like Crap. boost started to come on strong but immediately had a bunch of misfires and a code for the pressure senor. not sure what I am doing wrong until...

There are many, many places where you have multiply and divide... in ASM, not in maps.

Is this the cause?

Im using that 551r file with great results with 4 bar vw sensor set map DSLGRAD to 875 and DSLOFS  62.50 (make sure you're using a 5120'd XDF.) I would log ambient pressure and see if your map sensor is reading properly.
 I tested and solved my issue a couples posted back. There were a few more p variables i needed to double in the .ecu file for me7logger. Correctly reading the right pressure and boost levels now. Ive attached the .ecu file with values for the 551r 5120.

If it is linear and has 0-5 v output i bet it can be scaled to work with the ecu. May take a couple tries to get it to read accurately. The 4 bar vw one will be a plug in fit to your ecu harness and wont have any guess work associated with calibrating it.

I've done hack on BAM 1.8t. I have 3 bar map sensor. Baro pressures on vcds are equal but VCDS are logged 820 mbar pressure so it is devided as I done in pressure maps.

I have another problem. I have on LDRXN flat 180 value so I should have about 1.1 bar boost. I have over boost, cause on my boost gauge I have 1.5 bar peak and this drop to about 1.4 bar and I don't have any throttle cut or anything. Whats going on?

Of course on WOT requested boost equal actual boost (1.1 bar logged) so why boost is additional 0.4 bar?

Impossible to tell w/o logs, plus there is no way of knowing if you got the hack right.

I will do logs tommorow.
Hack I've done multiple and devide pressure maps by 1.2 to suit them to my map sensor and DSLOFS , DSLGRAD is calculated to 3 bar map and devided by 1.2 and 1013 hpa assembly points are devided by 2? Maybe they also should be devide by 1.2?

Hi would any one be able to direct me to the location of the 1013 divisions on a 081H file please
I believe I require :
pvdk_w #1 or #2
fvpdkds #1 or #2
fho_w
frhodkr_w

Understood. I don't use VCDS for anything except logging adaptation values, but I can see how this would be valuable.

I will add the changes to the M-box bins posted in this thread if somebody tells me what to mod :)

Thanks, and sorry for the misunderstanding.

I didn't play much with the OBD communication protocol, but here's a quick hack to make VCDS display "proper" (and not halved) values with 5120 mod:
Valid for M-box only!

0x6A338:
change 7D to FA
0x695B0, 0x69416 and 0x6B646:
change 7C 84 F1 C8 to EA 00 6E A3
0x69402:
change F3 FC 43 8B EA 00 BE E6 to F2 F4 84 A2 EA 00 6E A3

Now VCDS will display proper values (but likely will still max out at 2550ish - not sure, need to test this).
EDIT2: Added overflow control. It's not very elegant, but should work.

Definatly related to the ASM divisions, ask me how I know lol  ;D
I noted that in your OLS you have the asm division fvpdkds, but this should be fpvdkds.
In my own 1.8t disassembly, the first occurance of #287h is going into pu_w, and the second occurance goes into fho_w. The last 3 are (I think) the correct values for the fpvdkds and fho_w divisions. Is this the mistake you made, britishturbo?
Oh by the way, nice work  ;D I hope to need this hack in the near future.

This will still max out at 2601mbar you need to change the formula.

Here is a map pack for my software including asm divisions and seperate 5120 maps folder:
Audi A4 1.8T 4B0906018CA 0261206917 0003
Factors have not been altered in this map pack by the way, but maybe it is nice to do this after modification of the bin. There is a division of pu_w in the file, I left this one untouched for my initial test since there is no mentioning of this one in the files I've seen.. I just collected a bunch of divisions from my disassembly. ** Since my test worked, this division is now removed from the map pack.

I reworked my own file now, for test. I just dont really understand the logic applied to ZDSU. It is a time constant, why would you change this? In Bissche's file it is set to 12, in the txt file it says sqrt/multiply by 2. Now that would yield a new value of around 3.5, since the original value is 3. The FR says it is 5. I left it at 3 in my file for now, since I dont expect this constant to work against the hack.

* Did a testrun today, and everything works as expected. Awaiting 3 bar sensor for 2560+ test.
added *.ecu file with 5120 mods and original (unmodified) bin.

Tried file posted here on forum, 4B0906018CH 0261207216 360101 on my newly rebuilt AJQ engine (with wiring harness and ECU from an Euro 4 engine).
Rescaled KRKTE for my 1000cc injectors with no luck. Car won`t start. Has spark, but injectors aren`t opened at all (after emptying 2 batteries few drops of fuel are visible on manifold). With same file, but without hack and KRKTE recalibrated engine starts very easy.

Is there any version of file for 018CH with 5120 hack that works 100%?

Thank you.

All wiring harness was built from scratch, also the engine was rebuilt after 2 years from dissasemble, so i`ve initially thinked is my fault :) Checked every wire, every signal with multimeter and then with osciloscope and ended up to think is wrong software. This is not original ecu. Original ecu was for narrow band lambda.

That`s why i`ve tried to start engine multiple times.

Tried with file posted above by our colleague, 4B0906018CA 0261206917 0003.
Engine won`t start even with correct KRKTE. Measuring blocks are wrong. No useful informations in first 60 blocks, just some vehicle speed, knock voltages and few more informations, but nothing about boost, maf, temperatures, etc, so i guess this is not compatible with my hardware.

kwp1281 vcds fix to show actual pressures with ida

search for 'mov rl6, plsol'
typically it looks like

mov r8, #12h
mov rl7, #0FAh
mov rl6, plsol ; desired pressure
...
mov r8, #12h
mov rl7, #0FAh
mov r4, pvdks_w ; actual pressure
....

change both parts 12 to 08 ; FA to FC
mov r8, #12h -> mov r8, #08h ( E6F8 1200 -> E6F8 0800)
mov rl7, #0FAh -> mov rl7, #0FCh (E7FE FA00 -> E7FE FC00)

I must have overlooked something.
Car is running a bit nervous, jerky and is ultra sensitive on little accelpedal moves.
On wot it drives like normal and everything looks fine from the logs.
At the beginning of the logs there is a difference in desired lambda, i think because of AC on in one of the runs.

Lambdacontrol goes crazy in the 5120. What is wrong here?

I reworked my own file now, for test. I just dont really understand the logic applied to ZDSU. It is a time constant, why would you change this? In Bissche's file it is set to 12, in the txt file it says sqrt/multiply by 2. Now that would yield a new value of around 3.5, since the original value is 3. The FR says it is 5. I left it at 3 in my file for now, since I dont expect this constant to work against the hack.

The sqrt(x)*2 thing does't make much sense...

I finally got the 5120 hack running on my 1.8 H-box after the 1013 divisions, did some testing yesterday and it was holding steady at 1.9bar (28PSI) @ my pressure gauge.

I was running into 50% opening blade issue @ wped=100. This really got me stuck for some time.
I have been reading this thread all over and I couldn't find anyone who may have got into the same problem.
Now BoobyTrap pointed me into the right direction for this.

There are 2 options for this to overcome, 1st easiest one is to set CWPLGU from 0 to 1 which will cause to pu_w to calculate plgru_w instead of plgruo_w to calculate plgru_w.
This is the same thing for plgrus_w.
The second option is to divide the tables and axis from map KFPLGUB and KFDPLGU as they use ps_w and pssol_w as input (which has been divided by 2 because of the 5120 hack). (Correct me if im wrong)

Anyway regards for BoobyTrap for pointing in the right direction for this cause.

http://nefariousmotorsports.com/forum/index.php?topic=12744.msg110216#msg110216

I am now running with 0 281 002 316, 4 bar map sensor. I still need to do some calibration with the map sensor because I am not seeing same pressure in the logs as I see on my gauge and I can see my mixture is leaner than whats in my flash.

Running now with DSLGRAD 352 and DSLOFS 104 but I see somehow a difference of my new calculated DSLOFS 144,37.

I couldn't make a good log yesterday because of the rainy weather which caused lots wheelspin.

Going to get myself the RS6 recirc valve and make it circulate back to intake again and get my MAF working again, but that's still a work in progress.

Will update soon with logs.

A few other possible map changes on ME7.1 (2.7t)

DIFFMAX (pus_w) - probably should divide by 2, but stock probably won't hurt - just makes diag less sensitive
PUSMAX (pus_w) - We're allowing double pressure, so leave alone
PUSMIN (pus_w) - probably should divide by 2, stock is 450, and 900 is likely not so good at altitude? Again, this probably just makes diag less sensitive than stock
PSAPES (used instead of pus_w when CWPKAPP bit 0 is set to 1) - leave alone unless you need CWPKAPP for something
NDLDIAPU axis (pu) -probably should divide by 2, stock is 600/1000, and 1200/2000 is likely wrong - only two output RPM values (2600 for high altitude and 2160 for low) so maybe it doesn't matter; if we leave it alone we'll always see 2600. Either way, for big turbos, the RPM needs to be shifted up anyway.
DPVDKDWG (pvdks_w - pu_w) - ?

listed but not in my mappack?

HSLDSUA (pu_w)

PUSMIN (pus_w) - probably should divide by 2, stock is 450, and 900 is likely not so good at altitude? Again, this probably just makes diag less sensitive than stock
PSAPES (used instead of pus_w when CWPKAPP bit 0 is set to 1) - leave alone unless you need CWPKAPP for something
NDLDIAPU axis (pu) -probably should divide by 2, stock is 600/1000, and 1200/2000 is likely wrong - only two output RPM values (2600 for high altitude and 2160 for low) so maybe it doesn't matter; if we leave it alone we'll always see 2600. Either way, for big turbos, the RPM needs to be shifted up anyway.
DPVDKDWG (pvdks_w - pu_w) - ?

listed but not in my mappack?

HSLDSUA (pu_w)

PUSMIN
must be changed necessarily.
had the problem because a friend lives a little higher. Car run very bad

HI people

Is it nessecary to divide MSNPCV axix by 2  or I can fill axis with lowered hpa?
I'am running 5120 hack on 06A906032HS with little of bug but relative is okay.

Thanks
Regards

Does anyone know the Hex address to change the x-axis for KFDLULS?

I am trying to make the values half of what they are but I haven't been able to find an xdf parameter for it. I have spent hours trying to understand how to locate the Hex address in the file but I am stumped. Maybe someone can give me a shove in the right direction?

Attached are snip-its of what I am trying to do.

The address you are looking for is 0x198FD, 1 byte/8bit with conversion 10*X on an mbox file.

Looking at your screenshot, the x-axis in your table definition likely already had the reference you were looking for. Open your table properties, select the Columns tab. If your "label source" parameter is set to internal (or linked), the address and associated parameters will be defined on the right side of that tab (eg, address, data size, conversion).  Note those down, create a new table defining the address, data size and other parameters on the general tab, select the rows tab and set number of rows to the appropriate size (8 in this case) with label source set to external, and input the conversion for this table on the conversion tab.  You now have a table containing this axis values.

Worth noting if you did not create the XDF yourself, the above assumes whoever created it had correctly defined it - at your own risk!

It was in front of me the whole time. :o . Geez, thank you.

I see your point. I was using NYET's stock M-box file with 3-bar map incorporated. The first picture i attached is my file, the second picture is the compare values with his which are halfed.

Hello chaps!

I have issues with the 5120 Hack for my 551 K box file (RS4).
Maybe someone can check it ?

Car runs like shit when I flash that file. I double checked everything but cant point out whats wrong...

I sorted it out. I think there where one or two values missing. I started from scratch and now it works.
But maybe you can help to show right values via VCDS? In your XDF there is a KWP Patch. But I think that wont work with my 3 Bar Sensor.


@mophk If you have a 551G ECU you can easily flash the 551M file. If you look through the Forum you will find the already hacked one.

The sensor used has nothing to do with a pach to read right with vcds, not my pach but basically it double the values(that are halved by 5120 hack) so it shows correct pressure...

You can always upgrade to K-box, only small changes needed like maf, throttle and componentes delete.

as far as I know, the 551m file on the repo from Nyet does not work. the RPM isnt stable either. I have not tested this myslef yet, but someone tried the premade file from nyet and it did not work.

No clue what you are referring to.

It isn't as if ME7.1 is a mystery. Any such problems should be trivial to find and fix.

Especially since I'm running that file (or a variant of it for larger turbos).

Would you be able to post the working one? I'm currently without a test car but a confirmed working file vs the repo file would make my life easier. don't get me wrong, I saw few times that you had problems with mixed up files. or maybe give a count of changes done for the 5120 on your file?

once i have my car ill be able to troubleshoot it a bit more but I just wanted to make sure, the code is correct

Hi,
Before 5120 hack, i installed 3bar sensor, set DSLGRAD/DSLOFS and everything was ok, done about 1000km with no issues and up to 1,5perc fuel trims.
After 5120 hack, i have pulsing rpm, no torque at low rpm. Throtlle is closing, when rpm drops. Noticed, that fho_w (AltitudeCorrectionFactor) 0,48-0,49, while with no-5120hack file fho_w about 0,99-1,01. This is may be problem?

Thanks for reply. I followed every step by Bische's project text file in first post(at first, tried with S4Wiki list, but it's not full), and in 30+pages didint noticed (maybe missed) additional info. Maybe you are talking about KFDPLGU/KFPLGUB?

No,hes talking about DSUGRAD and ofs... it is prolly reading ~500 mbar or so which drives the correction factor, if you did the hack according to text file you cant miss it.

A quick question
Has anyone had experience with 06A906032HF file? Its a tip copy of popular HJ file which im done a few times
Those HF which im usually used for a dsg conversion and now its time for 5120 but the engine stalls after 1 sec
Its not immo issue, works well wo 5120
Wdkba is always 0 (dk soll too, i didnt remember its acronym)
Asm changes applied as usually, checked it twice with ida
Ill post logs later but maybe anyone already been in that case
Thx in advance

Stall after 1 sec? prolly dumb idea but that sounds awfully like checksums or some checking kill command if values/logs check out, recently on one file(code mods etc.) i had bad checksums which me7sum didnt fix, winols fixed it. What do you sum with?

edit: Didnt read the DK issue part, still worth a check tho

Thanks. Yes, my car shows 0,5bar while not running/at idle. I thought it's normal (because of divided DSLGRAD/OFS).
So now i should get 1,0bar ambiente pressure?

Finally i got my first car running on 5120hack  :D
Problem was stupid - after 1013 division correction, i didin't saved file.
I made few kilometers and car runs like before 5120 hack, no fault codes, fuel trims in 1perc range.
But where is one open question about KFDPLGU/KFPLGUB:

BTW, I think I got my 1.8T running with 5120 hack. I used BOSCH 0281006059 (03K906051) sensor. Done some limited testing already and so far looks good!
There is a couple of 1.8T 5120 xdfs floating around but none of them covered the issue I was seeing; my throttle plate was not opening to 100% on WOT.
Turns out there is a map called KFPLGUB which is used instead of ambient pressure for calculating pressure ratio across the throttle plate (used in throttle maps) if CWPLGU = 0.
Apparently on most cars CWPLGU = 1, hence this map is not mentioned in the 5120 hack threads, but on mine this was set to 0.
I think the solution is to either divide both the axis and the table by 2 or change  CWPLGU to 1. I've done both just to be safe and now the throttle behaves correctly.

Unfortunately I cannot upload the xdf as the forum tells me that the site storage is full! If you'd like to have a look send me a PM.

I devided in my file KFDPLGU/KFPLGUB axis/map like BoobieTrap reccomends. Everything looks good at the moment. Should i leave it devided, or back to stock. P.S. Set CWPLGU to 1 in my opinion bad idea, because KFVPDKSD/E maps depends on it


Title: Re: The 5120 hack - Running up to 5bar absolute pressure on ME7.x
Post by: nupustas on October 27, 2021, 08:59:31 AM
Update.
5120 hack works great. Up to now, i was running with divided by 2 KFDPLGU/KFPLGUB maps and pressure axis; and today decided to try stock values.
And it's terrible - throttle plate angle max 50percent.
I think there will be useful information. Maybe worth to add this at S4wiki

Hi,
I've read through the whole thread multiple times and tried to set the 5120 hack up for my AUM on GT2871R Turbo.
Currently running 1,8 bar (2800 bar absolute) in open loop at 92% N75, so far absolutely fine at around 400hp.

I'm using a 3 bar 0281002976 bosch sensor, part number 038906051C.

But when running 5120 hack, I get a strange reading in my logs.
The max value of boost is just 1090 mbar.
Multiplied by 2 it is 2180mbar - but I'm running 2800mbar actually..? I expected it to be 1400mbar to match my actual boost.

Can anyone take a look at my file? May I've overseen something?
Why do I get wrong log values?  ???
File attached is simplified a bit.
Thanks in advance.

Yes, you could do that, hope you're not on k03's still though, they won't be too happy with you if you use the 5120 as intended! Grab the xdf from nyet's post and get to it. http://nefariousmotorsports.com/forum/index.php?topic=3027.msg29815#msg29815

Alternatively, grab one of his base files and then copy over your stage 2 settings. Probably the easier route imho.
