I did a B18B swap a while back. I used the rywire conversion kit to go from obd0 to obd1. So, therefore I am using the obd0 crx si injectors still. I am using a PR4 ecu from a 95 integra ls. My problem is that I am getting bad gas mileage and I can smell unburnt fuel coming out of my exhaust. Nothing has been modified as far as the fuel systems goes. I also ocasionally get exhaust pops between shifts. Why is this happening? Do other people have similar experiences?

 

maybe change fuel filter/clean injectors i dunno can't hurt though.....? or adjust timing?
