I was wantin to know what type of ecu is in a a 93 cx hatch. I have a p28 ecu and i was wondering if that would help me out at all. I've heard that it would help my vtec. I've got a $50 dollar vtec controller on it (nothin fancy but it works). Also would this increase the redline of my car? I know the cx motor didnt redline that high but i have a d16y8 in mine and would that p28 make a difference?
