OK I have acquired a 1991 Honda civic Hatch.. previous owner swapped in a D16y5 with 5spd but left the dpfi. I have come across a mpfi manifold and im looking to do the swap but my question is what ecu will run this y5 properly as i know its a vtec-e motor and its origin is obd2 so original ecu is out of the question.. is there a alternate choice? i have googled this many hours with no real answer..
