I just did this and the car feels completely different. It's exactly as you said - it feels like the turbo lag is gone. I'm convinced that this is 100% psychosomatic, but I'll take the placebo effect all day every day! It's awesome. Thank you!!! |

It really shouldn't be placebo effect though, the 'throttle adaption reset' option as far as I remember is an option on the oem Istep software and BM3 software. Definitely does something. |

Pretty much every car manufactured over at least the last 10 years has this adaptive/learning strategy. There are several things in play, but the ECU is always adjusting parameters based on the driving situation and environment it sees to optimize drivability, emissions, fuel economy, power, etc, all while compensating for wear and aging. It really isn’t a bad thing, and it’s also necessary to maintain compliance over the life of the car.
A side effect is, that there’s only so much driving history going into the adaptation so if you only do light throttle, granny-shifted, A/C-on driving in 100F and then hammer on it on a cool morning, the first time or 2 it has to re-optimize and undo the damage you did by driving like grandma ! I have quite a bit of experience tuning Audi’s 3.0T platform, and yes, there are people who will say things like “I have a Stage 2 tune, and in sport mode, the power is great, but driving in traffic can be a bit nervous and twitchy. I’m going to remove the tune “ Most enthusiast board responses to that were WTF dude?! Take it outta sport, why did you tune, etc. Different strokes...and there has to be a mechanism to deal with it |

That being said, as a disclaimer, I cannot recall with certainty if the above method is also the method for resetting the TCU as well (I seem to recall that it is, but am not 100% positive).

Just a FYI, i did this on Saturday. Drove my car this morning for the first time since then and noticed that my throttle is a lot more linear. I also completely forgot that i did the reset on Saturday, so it wasn't like i expected anything different (placebo effect). The power comes on quicker and more progressively. The M2C is my DD so i generally don't misbehave on the road and since it's fall in the Pacific North West, the roads aren't exactly conducive to spirited driving anyway. But when the weather did let up a little, man, this thing flies.

Thanks for the fix! I've noticed too in drive mode and have a similar driving style (daily through city and my weekends in the country). Sports plus and sequential mode gets it moving though, every time

I did this a few times on my 328 and my 340, but haven't yet on the M2C. It seemed to make some difference if it had been a long time and road conditions had changed my driving behavior (like going from winter driving habits to "ooooo! SUN!" habits). I've generally done a reset when I change back to my summer tires, but I don't think I did it last Spring.

Resetting the adaptions does help improve a modern vehicle's response and throttle, especially those with a DCT, as some have pointed out.
At WOT, under aggressive driving or "manual mode" for DCTs, adaptations won't matter. Adaptations are more so to make leisure and everyday driving more tolerable since the car essentially learns you and your behavior. Newer vehicles even saves your driving patterns keyed to the navigation routes. You can reset the adaptions with just a $10 dongle and a free APP but I use ISTA+, which gives you the option to reset specific modules, not just the entire vehicle but either method achieve the same result. |

Just a point of reference... It seems the throttle adaptations are different depending on mode. I've been driving more in Sport when I'm in traffic and now, two weeks later, the lagging throttle has returned. I'm only using sport+ when I can hammer on the car, and it's still snappy. Just something to think about ... Probably will need to do the reset at least once a month.
A buddy is a master tech and he didn't think there was any issue doing the reset over and over. Fuel econ may suffer, but... So what |

Had to do the reset procedure for Stock/M1/M2 mode for all of them to feel fresh Those who don't complain probably only enable the "Sport Setup M1/M2" configuration on empty roads and revert to stock basic for daily driving. Start & Stop Traffic, long queues and just city driving are what fucks it up.

Would going from Stage 1 version 8.7 to stock to Stage 1 version 9.1 also reset the throttle? ...because ver 9.1 feels faster to me.
(This is NOT my DD, so it could just be in my head...unless ver 9.1 itself is a faster tune) |

Did this last night, forgot about it, and after driving this morning, I was surprised with some extra "oomph" down low.. as well as some more linearity and a loss of some lag.
I daily drive to work, and not a far distance, but always have Sport+ on. Whether this is psychological or legit (I believe you all ), something changed! |

Resetting the throttle response?
Earlier in a thread that I cannot find now, was a way to "reset" the throttle response of the car. Can someone direct me?
Thanks |
