Mhd reset adaptations

Hey guys
So I re flashed my s1 - took only 4 minutes, and removed the crappy linear throttle- I swear it made my car feel like mush-

The change hasnít really make it feel like it did stock- and I want to reset adaptistions- I donít know why adaptation would still apply after flashing without the linear throttle option selected.

Do I just plug in tablet again and go to reset adaptations ?

You can reset the throttle adaptation or just keep driving the car and let it adapt.

You can let it adapt on its own, or if you want to clear the entire history of the adaptations, you can reset it. For the throttle reset, plug in MHD with the ignition turned on, reset the throttle adaptation, then follow the instructions in the app about turning off/on ignition and waiting. If you reset the throttle adaptation and neglect to follow the instructions then you will get a CEL and a throttle related code. This happened to me when I reset it and let the car sit for an hour without restarting it.

After the adaptation reset, the car may run a bit odd and the idle may not be smooth, but give it time and the car will learn.

Thanks for that advice !
There should be a sticky warning for the s1 flashers to read up on linear throttle - I kid you not my car became so shitty to drive- it wouldnít downshift as sharply , feel like starting in wrong gear-
Evet since i reflashed yesturday itís improved some but I can tell itís still not back-

On your point on following protocol exaclty with the reset Iíll leave it alone I donít want to risk headaches-

Iím enjoying the tune more today after the reflash and removing the linear throttle

It should return to normal in a few days. I didn't like linear throttle at first either.

Might as well clear the adaptations and let the car re-adapt again.
