Hey just wondering if someone here could help me out. I have a 96 civic cx with a b16a2 swap which is running off a p73 ecu. Here is where the problem is when I'm driving it I get on it and at 4500rpm it pops like vtec but u can feel car being held back until 6000rpm when it takes off like a rocket. I think the p73 vtec is at 6k but don't understand wats going on at 4500. I have a p2t si ecu for the motor but can't use because of obd2a harness. What r my options? Thank u for your time
p30 i think is the ecu u need..either that or the p72. I'm not sure, wait for somebody with solid facts. Sorry
