I just put a JDM B18C1 in my 93 civic, I'm running the p28 ecu from the D16Z6. I was told that on factory settings it is robbing my B18 of horsepower. I just bought my first honda like 4 months ago and never read much into them before. I dunno if should ship it, if I do which one, or if theres a way to program the ecu myself without a chip. any suggestions?
