ARCHIVE THIS
hey good work, should come in handy for some ppl 
not sure if its really worth an archive or not just cause its lacking some info, and some is sorta wrong…if you know what you’re talking about then its a good reference guide, but if you don’t its easy to get confused.
for example, it says that the pr4 is the 90-91 ls/gs ecu. Whats wrong w/ that?
-pr4 also came in 92-93 tegs…but in obd1 form opposed to the obd0 90-91 pr4 ecu
-pr4 wasn’t only in the ls and gs…it also came in the rs
-also, 90 and 91 ecu’s are different, and not interchangible
I’m not so sure about most of the other info cause i’m not as familiar w/ the other ecu’s…but just a warning, don’t think this chart is 100% accurate. I’d suggest using it and then getting a second opinion elsewhere to make sure you don’t buy something that isn’t gonna work on your car, or sell someone the wrong part…etc…etc.
To get a comprehensive list of honda/acura ecu’s would be one hell of a job! There are so many different versions of each one, and you’d need to list the whole code on the side…not something i’d want to spend my time compiling! lol.
yeah i didn’t know much about it , so i thought i’d post it so maybe someone can make somethin useful out of it… 
Whats the diff between the PW0 and the PR3?
The cars they came out of and the programs are a bit different.
Ben
Ive noticed the PR4 on a lot of different things in my car… (its a 91 ls) … but recently i found a few PR3 parts, does this mean someone used parts froma different car to fix mine? possibly? or are those codes not even related?
You mean like cam gears? A lot of B-series parts are interchangeable. I wouldn’t be surprised if it came off the assembly line with those parts.
i couldnt remember at first, but yeah the cam gears… and few other bits as well
