Hello guys, I'm doing a swap into my civic its an h22 into em1. I was wondering if I can use the p13 ecu with with the 97-01 prelude injectors. Those are saturated 280cc injectors. The p13 that I have is from t he obd1 92-96 prelude which originally was for peak hold injectors which need resistor box. . Do i need a resistor box or no? Any mod that I have to do or do i just plug and play. thanks

 

bump? please advise if you know. thanks alot

 

no you dont need it

 

you should be able to run the saturated injectors just fine. People use p28 ecu's with peak and hold injectors so the concept is forward and reverse compatible....

 

You will not need the resistor box, but the fuel curve will not be correct. Your ECU was tuned for bigger injectors

 

thanks soo much for the reply!
