i have a b18b in me eg, its an obd2 motor converted to obd1, all obd1 ecu an dizzy an wire harness an injectors, i have a pr4 ecu, will this work or do i need a obd1 p75?

 

There are OBD0 and OBD1 PR4. Both of them are designed for the B18(A/B) and will run your car fine.

The OBD0 ecu would require an OBD0 injectors and dizzy (CKP sensor has different number of teeth between OBD0 and OBD1/OBD2)

The OBD1 ecu will run the OBD2 motor (including the OBD2 injectors and OBD2 dizzy) with no problems.

-PHiZ

 

so even if its an obd0 ecu it will have no effect on how the car runs if its still obd1?

 

ok my ques is, if i have obd1 injectors an dizzy an harness, will the obd0 ecu work?

 

Nope, the nonOBD ECU will not fire the OBDI/II dizzy. The nonOBD injectors will work with an OBDI/II ECU (and vise versa) so long as you're running an inline resistor box. Just run an OBDI ECU.

 

yea i wasnt sure if the ecu was the ryt one, but i fixed the prob, it was the iac valve and map sensor on the tb, car runs good, thanks for the info
