    use with the P28 w/ ITR base map, why would you want to run obd2? 2 O2's? and usually less power with obd2's?

    p72 won't work... it wants IABs and the itr doesn't have it.

    cheap way: p28, XYZ chip here, VAFC + dyno tune it
    better way: p28, hondata, dyno time

    i dont see why p72 wouldnt work, although it wont be as good as a tuned p28. the p72 wont throw a code or anything if the IAB's arent there. it doesnt on my gsr with skunk2 intake manifold. but with the p72 the vtec engagement will be set for the gsr at 4400 so thats not very suited for the motor, but it will work, might lose some power due to it.

    and IAB's are the secondary butterflies in the gsr intake manifold.

    why not just get a conversion harness and run the p73? if you are just gonna leave the motor stock for now i would think that would be the best computer for it.

    IAB intake air bypass
    What year is the civic?
    What year is the C5?
    The p73 is the correct ECM for the C5. The P28 is the big fix all.

    Tunability, and it plugs right into the OBD I Civic (because it'sfrom them, si/EX).

    OBD II ECU, not as tunable, requires purchase of additional wiring harness to plug it in, looks for too much crap that you don't need.
