i just bought a 92 civic si with a b20 vtec, it has a gsr head on the b20z block. the guy i purchased it from says the gsr ecu runs the setup perfect,i have done some extensive searching and am still a little worried. the car runs perfect as far as i think, but i dont want to go half assing something. give me some opinions on the best ecu for the setup.

Bring it to a dyno. DO a couple runs, have the A/F checked out, make sure its not runnig lean. That should help.
