long story short i have a euro p28 and failed 2 times to get it running the way i want on my dohc b16a2. my friend's gf has a 94 ex coupe. can i put the euro p28 in her car and still have it pass smog? the sohc program is a euro stock program i think. so that i can use her ecu to get chipped??

 

I don't think the euro ecu looks for any additional sensors that would not be present.

However a USDM ecu on a JDM/EDM, the ecu will be looking for sensors that are not present.

You should be able to chip either of them.
