Hi Folks. I think I'm experiencing throtle cut because of max REV timer reached causing missfire.
That brings to you guys two questions.
1. I thought that the throtle cut only happens during the launch it self. Didn't know that it would do the same throtle cut at high RPM WOT while racing! Is it possible that it will do the cut max rpm during normal draving?
2. What can I do to resset that timer? unplug batterie would be anough or need to reflash everytime?

Sorry for the noob questions.

I love Nefmoto Tongue

hello!
its possible add launch to volvo me7.0/me7.01?

D:\Volvo>ME7Check.exe 0261208289.hex
==============================================================================
ME7Check v1.12 (c) mki, 06/2004-05/2012
Checking file 0261208289.hex (size=1048576)
Reading Version Strings...
-> Bootrom Version = 44.44 (UNKNOWN)!!        ** NOT OK **
-> EPK = 45/1/ME701/19///70195G6/70195G6/140504114927/..
-> ECUID data table not found                 ** NOT OK **
-> file not recognized as ME7, stopping analysis

So you want to launch like the cool Subaru/Evo kids? As it turns out we can! And it's pretty easy. It works like this.. ME7 has a bulit in raised rev limit function which is unused by default. We set it up so the standard rev limit (NMAX) becomes the launch rpm and the raised limit becomes the normal limiter. It's controlled by VNMX so that as long as the car is below 1.25 km/h the launch control limit is used. Above 1.25 km/h the raised limit aka the new normal limit is used.

Here are the maps I modify including their M-Box addresses

CWNMAXMD (8-bit) Codeword Drehzahlbegrenzung Set to 1

VNMX             (1157E)     The vehicle speed for activating the raised (normal) rev limit. We set this as low at it goes (1.25 km/h) so the launch control shuts off as soon as you start moving off the line.
DNMAXH         (16304)     This is the RPM above rev limit when the fuel cut comes on. Tweaking this helps make more boost on the limiter. I use 50 RPM  (Keep in mind the maximum RPM limit is NMAXOG + DNMAXH)      
ITNMXH          (16308)     Dwell time under lower limit before activating the upper limit. We set this to 0 seconds
NMAX             (1630A)     Ends up being the launch RPM. I've found 4500 RPM works well.
NMAXOG         (16312)     This is the raised RPM limit which becomes the standard limit. Mine is set at 7100 RPM
TMOTNMX       (16316)     Coolant temp for activating raised (normal) rev limit. We set this at -48 so that it can activate at any coolant temp.
TNMXH           (1631A)     This is the time duration of the raised (normal) rev limit. We set this at it's maximum value of 655.3500 seconds. I haven't had a problem yet with this and have been testing for months.

And here are the results! http://vimeo.com/14266421

Eventually the plan might be to make this into a self installing patch file like the Subaru guys use.

I just uploaded a Stock M-box with this code http://nefariousmotorsports.com/forum/index.php?topic=152.0

Additional IMPORTANT Info!

Be aware that when using this method of launch control there is a time limit of 10.9 minutes for driving above the launch RPM. Therefore I suggest you set this appropriately high, somewhere above your normal cruising range. After 10.9 minutes the throttle shuts off until the RPM falls below the launch RPM... This is a potentially hazardous condition so please be aware and implement this code at your own risk!

Additional additional info

Thanks to k0mpresd I've learned certain ECU's need the map CWNMAXMD (8-bit) Codeword Drehzahlbegrenzung (Codeword for RPM limiter) changed from 0 to 1

-Brandon

EDIT: Correction the map is DNMAXH not DNMAX

Does anyone know what more to do for it to work on med9.1?
Even with all these changes, nothing happens.
Is it some kind of codeword?

Hi everything!

I have 1 question - i set NMAX to 4500, this max value of RPM be used only at launch? On a run RPM will be limited on this value?

It depends how you set other limiters (temperature, speed and time) and how is raised limiter set.
If you set VNMX to lowest speed (not 0), TMOTNMX to minumum (-48*C), TNMXH to maximum (655,35s) and ITNMXH to 0 it should be using NMAXOG when driven and NMAX only when stationary.

There is one thing I want to be sure about.

If Iam using the auto add script I have to assign the code space myself. Read somewhere that I just have to look for large "FF" areas. Is there anything else to consider finding empty space ?

You posted in wrong topic I suppose as this one is about poor people launch control (using NMAX/NMAXOG etc).

I agree. My fault. No extra code implanting.

Another person asked my same question so i thought id bump it. On the 551R XDF I only have NMAXOGGA not NMAXOG. I dont know if this is because 7.1.1 is different or something but im trying to understand. NMAXOGGA seems to be a rev limiter figure set originally for 6800. But i still cant get this working. It flies right by 4500 every time. I might try to adjust the DNMAXH to a lower number like 35 or something because i still have the stock flywheel on there. I cant be the only one to put Launch control on a 551R box. Someone help me out. Roll Eyes

A question for SixSeven or anybody else that may know: is there a CWNMAXMD bit in the 018P ecu? I have transferred the 4B0906018P - 352750 mappack to the offsets for the 018AA ecu, but CWNMAXMD was not in the definitions so I could not set this. Big thanks  Smiley

If memory serves, I did not have to touch this bit on the 018P.  As a matter of fact, I'm not sure I ever tracked it down either.
