ok so i converted my 99 auto prelude to stick with and h22a. curently running obd1 on a piggyback but need to run obd2 to pass smog...long story. my buddy said i can jus run an obd2 ecu but which one do i need and is there any other parts i need to swap out??? i really want to get my car back on the road for summer...its been sitting for 4 months now and im getting depressed =/ please can anyone help me?

 

just get an obd2 usdm ecu...P5M-A02

 

thanx man!!! i will start the hunt!!! so the dizzy can remain the same?

 

So you're using the H22A dizzy?

 

i dont think so...but how can i tell the difference between the usdm dizzy and the jdm one?
