Code: 45
DTC: P0172
Description: Fuel System Too Rich
I have had my OBDII disabled for over a year now since I'm running a race header without a cat. Today I enabled the OBDII again just to see what would happen and I got this error code. My short term and long term fuel trim is in the 20% range. This is weird because my car was running fine for over a year without this problem. This is on the base rsx supercharged PND ECU. The A/F is in the 11s-12s-13s range in closed loop. I've never seen it like this before.

You will get an error code if you don't have a cat. If there is a problem, post the calibration and a datalog.

Look at the short and long term fuel trim. Either swap in another o2 sensor to verify that the o2 sensor is working, or use an external wideband. If the lambda is actually correct, then look at the tuning.

I will get the car dynojet with wideband reading this saturday. If my stock O2 primary sensor is still working properly; the O2 sensor reading from K-Pro datalog should be exactly the same as the external wideband reading? Thank you for the help

If your fuel tables are that far off, even in closed loop the ECU will have a lot of trouble trimming it.
I'd tune part throttle if I were you.

As long as you dont have a cat and the 02 is far enough up in the tailpipe it should be close. If you can, disable OBDII and put the dyno shop's wideband in the second bung, this will ensure consistancy.

weird...I'm going to kick myself in the ass when I see it, but I could not find it. So I just right clicked on the link for the .7 version and copied the link...then pasted it and changed the 7 to an 8. Now I got it...thanks...not of any use to me anyways, I see it's for the pnf's cam angles.
