How do u re-set the ECU on a 89 crx si...i know i know..n00b Q..but my friend with his 2002 VW jetta 1.8t did it and his car ran HELLA better...

 

Take off the negative side of the battery for 10 seconds and that will reset your ECU, or you can pull a fuse, I forgot which one.

I doubt your car will run that much better.

Search button does wonders on this forum.
