I have a 90 civic hatch DX, 1.5 liter non vtec, I swapped this out to a SOHC vtec 1.6 liter. I used a 91 Si wiring harness and a 91 Si computer, but didnt change the inside wiring harness. Does anyone know what wires i need to change at the ECU to make this work?

Any information would greatly be appreciated.

Thanks

 

go to EF forum, and if you search I bet you could find it. I used to search for that stuff, and found alot of info. We don't have TBFI.
