Hello everyone I have a B18c1 obd1 p72 ECU... My ? is if I wanted to tune with Hondata s100 what would I need? I want to tune my car because recently I bumped the comp with JDM ITR pistons and have a few other mods itr retainers and springs, skunk 2 valves, Apexi Header and Apexi cat back exhaust?
please help thanks

 

An s100 is supposed to be tuned only by Hondata tuning facilities. The s200 comes with the tuning software though. It's cheaper and often easier to tune with Crome though.
