OBD1 P28 ECU - Injector Impedence?
I have a p28-a02 obd1 ecu. I am wondering if I still need a resistor box or not. Do the injector drivers use low or high impedence? What year did honda switch over from p&h to saturated? Also, with my Hondata, all I need is Hondata, p28 ecu, and harness right? No other wiring necessary? My engine is a obd-2 b16a2. thanks
All honda ecu injectors drivers will accept high impedance injectors directly, the non obd ecus used an external resistor box with the low impedance injectors.
You can run either injectors with that ecu. Just remember to have the resistor box if you want to run the P&H injectors. Likewise, no resistor box is required for the saturated injectors.

Wrong: 92+ Civics use high impedance (saturated) injectors.
