will this ecu work?
 

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.

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?

Re: will this ecu work? (wsiracerz)
 

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
