I thought the OBD0 PW0 was only in europe, not JDM

it most likely came from the integra XSi but they put EF down since it is the same engine. I don't know though

I'm running a PW0 with a JDM SiR b16a... not that I think about it, the compression ratio between the XSi and SiR motors was a little different (10.4:1 and 10.2:1 respectively) I wonder if running a pr3 would help my car run any better... I'm sure the program is only slightly different (if at all), but maybe its worth looking in to.

I figure if the ecus are different enough to get different names, maybe its worth switching it out and finding out how the car runs.

I ran a P28 in my supercharged del sol with a d15b vtec and it ran perfect. Great ECU. Athough somehow it no longer had a rev limit at 7200 rpms, rather at 7900 rpms. Ha Ha.

Right now I've got a p72 with hondata s200....and I f'ing hate it. I've either got a bad tune or a bug somewhere, and it's a coinflip on whether or not the car will run just fine or give me CELs and suprise rev limiters. I've got a couple leads on some p30's w/ aftermarket tunes as well as a skunk2 p28, so hopefully things will get better.

Oh also if you do a 16 valve head swap on your 8 valve EG, use the 8 valve computer, p05. When I did it ran great!! The only problem is the rev limiter atd 5300 ha ha.

Well I'm not having drivability issues anymore, but I still feel like I'm down on power. Also, I hate the idea of having to pay other people every time I want something changed. Then again, I don't plan on changing a whole lot on the car, so maybe one good professional tuning session with what I have would be the way to go. :fruit:
