Done.

(Please don't ghetto rig it like all the other Honda's around here)

 

b18a1 is obdo

 

Then that I do not know. But if you ever plan on tuning the car you're going to have to be OBD1. OBD0 is not tunable unless you plan on tuning on a SAFC.

:EDIT: or unless you have the money for AEM EMS.

 

thanks tho, i was more looking for info on what wires go were? or do i need to match the plugs and change the plug ends to match? sorry frist swap thanks

 

I know, I was just informing you so that it's not a disappointment when you go to tune the motor. Sorry I'm no help, never messed with anything staying OBD0.

 

hey thanks tho, anyone else?

 

Stop informing people with wrong answers lol

 

well since you already have mpfi in an hf, all you need to do is wire up the knock sensor, second o2 sensor if there is one, and u have no vtec so thats not your issue.
here you go, just dont worry bout the vtec ones or the IAB which is for b20 motors

 

What other ways can you tune a OBD0 motor without a SAFC (if you even classify that as tuning) or AEM EMS? I don't mess with OBD0 motors but I'm sure there is a program that one in a million people use and that nobody around here probably tunes.
