so i was wondering if an ecu from an 88 crx si will work in my car, if so what can i expect to happen? Any noticeable changes?

You have DPI. the si ecu wont work at all, unless you convert to MPFI.

Yes it will. It plugs rite up. I'm pretty sure i saw my friend did it.

it plugs right up, yes, but the Si ecu is looking for 4 injectors, 2 of which it will not find, as well as the two it does find are of different impedence. The DX ECU will not run an MPFI setup, so it would make sense that the Si ECU wouldn't run DPI.

ummm...okay?!?!? :confused:
if that were the case then why would anybody ever bother with the MPFI conversion? it won't work because DPFI = fuel flowing and going into 2 ports as needed. MPFI = 4 injectors with a programmed fuel flow directed by the ecu.
go to www.4thGenerationCivic.com and go to the "how-to" section. from there click the "performance" section. you will find all the DPFI to MPFI conversion info :bigthumb:
