Ok I tried searching but couldnt find something that would help me. Heres my scenerio. I have a 99 civic EX, a shop just swapped in a 97 usdm h22 5spd. THen it wouldnt start. They couldnt figure it out cuz everything checked out ok, then for the hell of it they plugged in an obII ecu and it started, ran like **** but started. So they gave me my car back like that cuz I had it scheduled to be painted. So that was like 4 months ago. THy're telling me that it would only start with a 96 usdm obII ecu or any JDM obII ecu, because these are the only ones without Immobolisers (spellcheck). If anyone can confirm this for me?? Cuz Ive tried 97, 98, usdm ecu's and it wont start...then I tried a 2000 itegra ecu and it started. PLEASE HELP!!!!!!!!!!!!!!!

 

I forgot to mention that ecu that shop tried that made it start was also an integra ecu.

 

Sorry again....let me clear it up a bit...theyre telling me a 96 USDM h22 ecu or any obII JDM H22 ecu. thanx

 

SOMEBODY PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Still waiting....

 

im not sure with the preludes but the rsx and type r s have it

just buy a jumper harness and run a obd1 vtec ecu
that way u can get a custom chip to run or hondata

 

I have a obII to ObdI jumper...but i just cant plug in a obI ecu right?? Dont I have to swap distributor and more?

 

u don t need a dist. only when converting from obd0-1 u would need a dist.
just plug in the jumper harness and ecu ur done

 

you need to get a 97 or up prelude ecu installed, but you need to take the 97+ prelude ecu to honda to be programmed accordingly with your prelude immobilizer before installing it....

once honda reprograms the ecu, your car should run very good.

one last note. if your swap did not include the immobilizer then a 97+ ecu will not work.
