I bought a project car that was a 1999 Honda civic ex coupe automatic trans that was swapped with an h22a motor and a 5spd manual trans. i have pictures the car runs but kinda rough it idles around 1000 rpm after getting warmed up. Money isnt an issue with this build. the engine wiring harness and loom looks atrocious and i have pics of the ecu which i believe is a p06 but has a bunch of piggyback shit on it as if its converted or something im not sure. basically im having trouble identifying what year my engine is and out of what model car. the stamp reads "h22a 3033907" on the engine if im not mistaken is it out of a 1997 accord wagon si R? i want to order a p28 ecu with hondata s300 v3 from hamotorsports.com and rewire the whole engine but my starting place should be figuring out for sure what engine is swapped into the car. thanks

just looking for some guidance in the steps i should be taking
p06 can support chips just like a p28, so it's likely not an ecu issue, assuming the additions were made for vtec support. it's a $10 kit last i knew of.
without the engine vin, it will be pretty hard to find it's true source. there's many variants from many countries all with different stuff.
ultimately, it doesn't matter, 'engine' -wise. what does matter is that the electronics match up. you want to have your obd1 ecu matching with obd1 distributor and so forth.
based on the high idle, it would think there's a sensor that's not wired correctly or missing or due to mis-match obd's the polarity is backwards.
or, it could be air in the coolant, or a bad vacuum line. It could be many things and will require some troubleshooting to drill down further.
I would suggest solving the problem with the current landscape. Adding hondata will not just instantly solve your problems, and may just create more gremlins to chase out.
