I'm going to be turboing my 89 crx si, but to run TE I need a 90-91 ecu. If I can't find one, I'll have to go with an SMC for cost reasons. I have a PR4 integra Ecu and can also trade my 89 PM6. Please let me know. Thanks.

 

i need a pr4 for my ls swap into my 91 SI. let me know how soon u need it?

 

Now will work for me. I'm getting all the parts together. Let me know how you wanna do this. I'll send you a PM.

 

Is that an obd0 PR4? or obd1? If it's obd0, you know you can run PM6 code on it right? I'm running a chipped obd0 PR4 with TE moded rom right now in my 90 CRX si.

It's probably an obd1.. but just in case you didn't know.

 

The date stamp on it is June 22, 1990, so that would make it OBD0 which means I can use it for what I need then, right? hmm, duh I feel smart. :P
