I have a 91 civic dx d15b2 dpfi and Im in the process of switching to mpfi, I have pm6 ecu can i use obd1 injectors without resistor box with pm6 ecu? i have researched and it is an unclear answer some say it will fry the pm6 ecu is this true?

Also I have obd1 dizzy from d15b7 is it compatable with pm6 ecu? I have already made a jumper harness for obd0-obd1.

 

you can use the OBD1 injectors without a resistor box with the PM6 - no problem

you cannot use the OBD1 distributor with the OBD0 PM6 ECU - they are not compatible - OBD0 ECU requires OBD0 distributor - OBD1 ECU requires OBD1 or OBD2 distributor

 

thanks for clarifying, what dizzy should I look for an Si or would a Hf dizzy also work?

 

88-91 CRX Si and HF along with Civic Si and EX all use the same distributor

 

I’m wondering how to wire it up
