    Between a PR4 & a P74 or P75? Other then being obd0 & obd1. My LS is a 92 but im using a pr4 and I have a backup pr4 but im wondering if I should be running a P74 or P75. I been having issues with timing and found that 3 wires were scalped by the ECU cover on the footwell. They had to do with the distributor. Well components in it. I had just noticed that the P74 P75 is a 92-95 Integra. Thanx in advance.

    obd0 pr4-90-91 teggy
    obd1 pr4-92-93 teggy
    obd1 p75-94-96 teggy
    the fuel maps are a little bit differant
    and you can tune the obd1 ecu's alot more easily and flexable than the obd0
    so you could run the p75 on your motor if you wanted but id just stick with the ecu for that motor

    Thanx for the advice. I couldnt find a single thing.

    You got any chipped ECU's that would work for my setup?
