Ok i searched everywhere and could not find a solution to my problem. I have a p28 ecu that was modified by hondata with the obd2a pugs. To get this to work on my crx which is obd0. Would it be as simple as purchasing a obd0 to obd2a conversion harness. Any insight would be greatly appreciated. Thank you.

 

First off, why would you want the OBD2A plugs on an OBD1 ECU, for use in an OBD0 car??

I would recommend doing a standard OBD0 to OBD1 conversion and running a standard OBD1 ECU... but to answer your question, yes - you should be able to just run an OBD0 to OBD2a jumper if that's the route you want to take...

 

The ecu was a good deal and at the time i was just getting started with my turbo build so i wasnt too knowledgable about what i was doing. now that i have the ecu i really didnt want to have to buy another. but thank you for your answer. I was thinking it should work that way but i wasnt too sure.

 

What engine are you going to use this on?
If your engine is fairly stock, then it will probably be worth selling that ECU or trading it for a stock ECU. Right now you need an adapter harness just to plug it in and then you will need to get it tuned since it is a used Hondata and you have no idea what mapping is loaded on there.

 

Thanks for y'alls inputs. It did end up working just fine. Thanks again.
