So I got this 1992 civic dx 4 door and have now swaped in a B16a SirII motor (manual trans block - 170hp) and connected it to a M24a auto transmission (don't ask me why.) My dilemma is that the current ECU won't enable the locking torque convertor (kinda like an overdrive). This means lots of wasted gas and lower top end. I was told to replace the ECU with a p28 ECU (37820-p28-a52 to be exact) and have it reprogrammed to redline at 8200rpm (motor's stock redline). Does this sound like a solution? If it works couldn't I chip the ECU instead of reprogramming?
