Needing a p13 manual trans ecu
And all I can find is p14 auto trans ecu
Will this work or will it cause issues?

Why would you use a non vtec ecu in a car that requires a vtec ecu ?

check engine light will be on for your trans and probably a few missing sensors but it will run and drive fine. we used an automatic p28 (not sure of ecu code) on a manual car that required a p28.

cool thanks!

obd1 ecu's you can convert from auto to manual, there are write-ups everywhere and its super easy. Personally done it on a p28.

The issue with what you asked is mainly in the VTEC area. The P14 will not run VTEC, hence the need for a P13. Might as well just get a socketted ecu and a chip burned for an H22, or a tuneable setup and get it tuned.

For a stock H22, you should be able to get a reliable tune on a socketted P28 or modified P06 for a couple hundred bucks from a few of the vendors here on Honda-Tech. If you need help finding them, just ask.

On the P28 and other OBD1 Civic/Integra ECUs, remove RP17 and solder a wire between the contacts of RP18. A leg off a resistor, a piece of wire, a 0 ohm resistor are all common to use.

If I recall someone was able to run a p75 chipped automatic ecu with the tcm on a prelude setup. I hope I can find that thread because it was so long ago....If I can't I'll edit this post out.
