Hi all, this is my first post (Sorry if it ended up in the wrong place, I wasn't able to post in "Swaps"). I have a 93 CB7 (EX) 4Dr, built in USA. I grabbed a 92 prelude H22A1, and ended up having to go online for a P13 ECU since the wreckers didn't have any here. I have everything in running condition, ive double checked the timing belt and made sure it was installed in a counter clockwise fashion, the marks still line up however even as I play with the angle of the distributor , it just wont run right. I completely rebuilt this motor before swapping it in, I know there are no vaccum leaks or fuel delivery issues. My thoughts are : Is are something I missed - wiring wise? Perhaps the P13 ecu isn't a direct PnP and requires some wiring to be changed in order to idle properly? Also, I have deleted the FIV, Secondaries , unplugged the EGR, got rid of all my evap crap (No emissions in Alberta) and looped the "Deleted" vac lines coming out of the IM. I'm sure there have been many USDM H22 swaps with USDM P13 in a USDM CB7 …. I couldn't find much info for wiring other than how to add vtec… any help would be greatly appreciated as I am at my wits end with this project !
I think the place to start is figuring out; Pinout / locations on the factory accord harness, pinout for the USDM P13, and whatever changes that are required in order to run the motor with this harness and computer … I heard something about the heated O2 sensor being re-pinned to EGR? but my EGR isn't hooked up … so IDK :'C pls help, you will be rewarded with burnouts in your honor when I get the old girl finally running proper and off buddy's farm for good !
