Ok i have a 00 civic si W/ a B16A2 (obd2 obviously) i want to know which ECU is best to run in this. I have heard P28, P72, P30.... i don't honestly know and i have heard that i have to Change my Dizzy over to OBD1...??? I have the conversion harness...i have purchased a P28 and threw my basemap in it... It ran like $#!+... like it was operating off 3 cylinders... ??? What ECU is easily found, and i can plug in and throw my basemap in and go...? i need to know this soon as were trying to go ahead and finish my build and get it tuned before Mar. 21st. (opening day at my local track) and yes i searched the internet... but keep coming up with different answers... Thanks Guys. -Twitch.
