so i have 98 h22a4 with a external coil distributer, its going into my 97 accord ex. I am running a chipped OBD1 P28 ECU. so do i need to switch to a internal coil distributer? if so what is the reasoning behind it. and I am going to use the either the accord ECU or the 96 prelude P13 ECU for inspection, will i need to switch back to the internal coil for that?

thanks

 

Check over at forum dot pgmfi dot org for H22 info. I don't think you would have to switch dizzy's though. Use the one meant for the H22.
