I tried this after adjusting stepper motor steps and my engine stopped. I was able to start it easily and I think the car is running better now. I have a 1996 MGF VVC.
I had adjusted the stepper motor previously but I didn't do the Reset Adaptations. I noticed a small improvement with gear changes being smoother.
I wanted to ask who has tried this and does anyone know what it does.I presume it sets the ECU back to factory defaults but I wonder how many parameters it affects.
After I noticed the improvements, I tried the reset of the TPS and the car seemed lumpy again. I redid the Reset Adaptations and it definitely ran better. I have had a lumpiness around 2000rpm when slowly accelerating after no throttle.
