so im swapping a obd2 b18b1 into a EF dx trim hatch. im getting a SI harness thats already wired for MPFI, its obdo, so what are my options as far as obd0 to obd2? jumper harness or backdate the intake mani and sensors? and ecu?, i also plan to turbo this motor, so what is a affordable program to tune on, i dont have money for hondata or aem ems, so is chrome really sufficient? reliable?

 

Crome would be sufficient but after just spending the last week or so tuning my car (from scratch) I can tell you that the Demon board + Neptune is probably your best bet. Crome isn't a bad program but still leaves a lot to be desired.

 

1. Run an obd0 to obd1 ecu harness
2. Wire your obd2 distributor into the vehicle.
3. Use an obd1 ecu

thanks, that post was to the point. could i run a obd1 dizzy? because i dont have one anyways. what else differs from obd1 to obd2?

 

I was told if you run an obd1 ecu, you need an obd1 dissy. For the tdc sensor to communicate properly.
