    I have a 90 hatch std and i convereted to MPFI all wiring is done correctly. When i plug in a PG7 or PM6 ecu i get a code 4 (cps) on the ecu. If i plug in my old CRX Hf ecu PM8 i get no codes and it runs fine. Could i have the incorrect distributor. Is there a difference between a CRX Hf dist. And a CRX Si dist? Or could my PM8 ecu be messed up in way way that it doesnt throw a code 4. Any help would be nice this is my first civic that was a DPFI originally .

    I'm pretty sure the distributors should function the same. It's gotta be the wiring.
