Whats the best ecu to put on my b18c1, that will eventually have hondata s300 installed with 8psi. Should I put a obd 1 p72 in it? I have a chipped obd1 p28 that was programed for a GSR but I found out that the p28 is a SOHC ecu. Does this matter even though its chipped and programed for a b18c1? if I run this ecu will I damage the motor?
