Dude that is not true like JET-6 said. If you were Testing your ECU for any fault codes and wanted to reset ECU you would do follwoing below:- To Erase you would do following 1.Turn the Ignition switch on 2.Rotate the diagnostic screw fully clockwise for more than 2 secs then fully anti clockwise for more than 2 secs. 3.Turn the ignition off. This completes the procedureand the screw should be reset back to the original position to maintain correct idle speed :mrgreen: Some original photos have not been recovered yet.

Disconnecting either battery cable for a few mins will also reset the ECU. As for making your car run better.. no.
