This is the throttle reset

Works with any car that has Driver Adaptive Electronic Controlled Transmission.

1. Get in your car, it doesn't matter if you close the door or not.
2. Turn the key to the on (not start) position, the position just before the starter turns over. BMW: press start button – foot off brake - all idiot lights on.
3. Press the gas pedal to the floor with the key in the "on" position. BMW: All idiot lights on.
4. Hold the pedal to the floor for five seconds, then turn the key back to the "off position". BMW: foot off brake press start button - all idiot lights now off (don't remove the key), then release the gas pedal.
5. Wait a full 2 minutes for a full electronic alignment. Don't remove the key.
6. Start engine, drive the car, notice the difference.


Gearbox:

You put your key in/hit start ONCE so the electronics of the car come on but it is not started.

Then hold down the gas, past the downshift point to the floor for 25-30 seconds straight.

If you listen, at about 25s exactly you will hear some "noise" and that is the tranny "resetting" itself to factor specs

Like I am sure you know these cars are smart and the auto tranny is no exception. It adapts and learns your driving style-but the catch is, which is why I noticed an improvment. Apparently it "learns" for about 1000 miles and then kind of "locks" those settings in so-to-speak. So however you drove the car off the lot or whover drove it off the lot-it was really those first 1k that determined how the autobox shifted itself.


The "noise" you hear is like a hard drive wirring noise, I noticed it when I did it and it definately makes a difference
