I have been workin on my H22 swap into my eg for about 2 weeks now. Its come along slowly becuase of my hours at work but it is very close to being done. I asked a few of these questions on honda-tech but cant seem to get a knowledgeable response. Anyways here at are the problems. I cannot for life of me find a concrete location for where to pin out the IACV TO be honest i think my first mistake was using the cx wiring harness. Additionally the vaccums on the h22 were all cut up and i have no idea how long they should be and where they go. If i could get some pics of someons H-swap vaccums i would be set. Also i plugged in a ECU out of my friends type-r swaped coupe (chipped p28) and it throws a few codes One for IACV and one for vtec pressure. I fixed the pressure but not the IACV yet obviously. but it also thorw a CYP code. I was wondering if this could be something hte chipped ecu is looking for like a more advanced timing or something becasue i have not messed with the wiring of dizzy in any way. I start it and it idles fine but when i give it gas it seems to hit a limiter at about 2-2500rpms. Im assuming this has to do with the IACV not being wired and not haveing a location for my O2 sensor yet since my header is not here yet. Any help would be appreciated.
