Are you sure that NASNOTKL in your file is limited to 2550 rpm? In my file it is 10200rpm (factor 40)

Yep, my mistake, I was going by the FR which says not to set it past 2550 rpm.. interesting.

Quote
P.S> look into MDKOL, NASNOTKL outputs nasnottm variable which is used in MDKOL (nmot < nasnottm) and thus skipping miasrl_w and miges_w

Interesting, nice catch, I did not notice the nasnottm is used elsewhere.

Any idea what the deal with "anti stall" is?

Eh.. Dunno, but i guess it is named so that the requested load by asr/trasmission would not be lower than it is actually needed for engine to idle properly.

Exactly. Look at the miasrs path... it isn't a limiter..

I'm an idiot. I should have done my due diligence.

MSR is "motor slip regulation", that is, off throttle, if the ESP controller detects wheel slip due to sudden drop in engine RPM (torque braking), it will send a CAN message to the ECU to temporarily increase requested torque.

It is lumped in with "anti-stall" because from the ECU perspective, it is the same function: temporarily increase req torque...

Work in progress, input welcome:

Just getting caught up on this thread, your comment about dumping power into the brakes if EDL is active - how obvious is this likely to be in typical driving conditions? Would I feel it, or notice one of the brakes getting warm?

I have no idea.. because I don't know if ESP on/off makes a difference. In theory, if the ESP module thinks ASR is enabled, maybe it is more aggressive with EDL? I have no clue. Hoping others can chime in here.

I agree with the theory! I'll disable ASR in the ECU and then go donut the shit out of the audi and see what happens Smiley In the name of science, obviously.

Also it would be super helpful to know exactly wtf the esp button does.

The ESP can be disabled from the ECU on the fly and re-enabled.
I mean fully off, yaw control etc. It will leave a code in the ESP unit though, and I am not sure if the ESP light will go off or if it will re-engage the ESP before you cycle the ignition.

I need to test it.

Thanks for taking a look, prj... I assume this method doesn't touch EDL? Know any specifics about the best way to disable it? (e.g. fake handbrake signal etc)

I don't know how this could be done on the fly without custom code or an emulator.

A little bit of custom code is needed yes...

Don't have a ME7 car to test, sold my RS4.
