    What's the the best ECU upgrade I can do for a 5G prelude. I'm considering throwing in a jdm p13 just to switch to OBD1. Anybody out there know anything bout all this?

    What year is your lude?

    JDM ecu's are not really better than USDM, and if your are 96+, then you'll still need a wiring adapter.

    5th gens are 97+ if memory serves.....

    there are several options. none of which should lead you to running a jdm p13. 113 mph speed limiters suck.

    i say get a p72 obd2 gsr ecu, since it still has betterfly control.
    if you go to an obd1 p72, not only will you need a conversion harness, but you will also need to re-wire the IAB's. see our 5th gen civic swap guide about putting an obd2 b18c into a 92-95 ex.

    on top of all that, the p72 fuel curve is NOT meant for the h22... so you will need at the very least, a vafc and some dyno time to get your a/f right.
