Re: Resetting ECM-ECU on old car - helpful?
If it had anything to do with adaptive parameters, it will "adapt" its way back to where it was in time.
The computer never quits adjusting. Changes in one direction may be slower than the other when it comes to safety. For example, timing is removed in big chunks when knock is detected and it is added back very slowly. A reset after a bad tank of gas my speed this but the car will eventually reach the same state whether or not it is reset.
