Yes I searched, but never found the answer. So my question is, since it's an obd2 engine, and I'm using an obd2 p5m (pretty sure that's the number) ecu for now, when I switch over to obd1 p13 ecu, I won't need a resistor set up for my injectors correct? I can use the obd1 computer on the 97 h22 injectors fine? I'm pretty sure I can, just neve got a definitive answer. My swap kicked off when I found a rebuilt (oem, 0miles) h22a4 complete with a trans and the two ecus for $650. Win? Lol also who wants to mod my motor mount?

Re: H22a4 swap questions.

I mean are the h22a4 injectors saturated high impedance
, and can be run on the obd1.

Re: H22a4 swap questions.

Found on Drift's H22 swap thread, Had to read it like six times.

10. I got rid of the resistor pack that is normally used on OBDI accords and ludes for the peak-and-hold injectors and bought some OBDII saturated style RC 310 injectors. They are easier to tune with and last longer with higher voltages.

Pretty sure thats the answer. obd2 injectors (saturated injectors) will work with obd2 and obd1 ecu's.
