Hello guys I recently purchased a 1992 hatch with a b18a1 swap. I have done a lot to the motor and was going to have the ecu work done when a friend offered me his Gude Performance Ecu out of his 91 integra. Will a simple jumper harness allow this ecu to run in my 92 car just fine? Or is there more I will need.

 

Unless he was converted to OBD-1 that is a OBD-0 ECU and you would be doing yourself a HUGE disservice by trying to step down to OBD-0.

 

Yes. This is true. Also, OP, I wouldn't trust a performance ECU. Optimized fuel tables are pretty specific to each set up. It's sort of like the generic chips you see. Unless Gude is the exception.
