    Do you know how to reset the ECU?

    Does anyone know how to do this in the Porsches. MB and BMW have a trick for this. Anyone has tried it?

    Well here is my reasoning. As you know new generation vehicles have what we call adaptive ECU, meaning the car adapts itself to your driving style. Since we have a tendency to baby the cars during the break-in period the ECU will have a different mapping than if let say you drove the hell out of it. So now the car has been broken in properly, I wonder if by resetting the ECU, you will not get an extra ooomph out of the car.

    This is often done on MB E55 or I had done it to me bimmer and the car feels much better and feels like it had just gotten a tune up.

    I just want to experiment and report back to everyone.

    On Bimmers and MBs there is a sequence with ignition key and throttle you go through and takes less than 5 min.

    Re: Do you know how to reset the ECU?

    Disconnect the battery for 10 minutes - it clears all faults from the central ecu and resorts to a 'normal' engine tune, so if you've been nannying the car for a while its a cheap adrenaline boost

    Re: Do you know how to reset the ECU?

    i was wondering that if you disconnect the battery, you would additionally loose all the info you programed into the system. i.e. preferences , phone #'s etc.

    Re: Do you know how to reset the ECU?

    how do you do that? just pull the contact from the battery?
    doesnt the alarm go off or something?

    p.s. is the e-throttle controlled by the ECU or does it have a separate processor?

    Re: Do you know how to reset the ECU?

    make sure the key is in ignition position 1 before you pull the negative lead off.
