Im sure this has been answered but i was not able to find anything, (i did not look very hard) the thing is Im looking to see if i can use a obd0 ecu in a car wired for obd2 and where can i find the jumper harness that will allow this. I did not look very hard because im in need of an answer fast im trying to buy a car, and this is a issue with the car. It is a 97 coupe with a built gsr and the obd0 ecu is fully tuned for what is in/on the motor. Thank you i advance for the input.

I don't think they make obd2-obd0 jumpers, And how do you know the ecu is tunned because some obd0 ecus are chipable but are not compatible with nicer eprom editors...

 

i dont know if it is tuned im going by what the person that is selling the car says. ithink im just going to go with a p72 ecu and send the stock p28ecu out to be chipped, any ides on who or where i can send this ecu so they can tune or chip to my set up for a decent price. thank you for the help as well.
