K, sorry to bother everybody again but which ecu should I be running with a B20B? The guy that put the motor in just told he didnt touch the original but today I went to Acura/Honda specialist in PTC, GA and I found out the ecu I have been running this whole time was a damn 92-95 Cx one....boy am I ticked right now....I cant even get ahold of the installer either.... The shop I just visited said try and get a 92-95 Prelude Si of a LS....what is anybody running?

 

whats your setup and are you running obd1? the safest would be to get the stock b20 ecu. most ecus will run that motor, even the cx one....but to run the motor well or run it optimally, you will definitely need more than a stock ecu. why not have the cx computer rechipped to run a B20? its possible and guys like us can do it. no need to swap ecus...make the most of what you have now you have options
