My problem. It seems that no matter how much I tell KPro to adjust my fuel under the boost columns my AF/R does not change or changes barely. I know what you're thinking my o2 must be bad, well I thought that as well and it has a brand new o2 in right now. I just adjusted my part throttle fuel today with success so it seems like this problem is somehow isolated to boosted columns only.

So after taking about 500 units of fuel out and maybe having the af/r change by .2-.4 (and not stable there) I am stumped and I don't want to damage the engine. I have a bad feeling that it is somehow related to the stock wide-band not reading worth a shit but it's brand new

Under boost it is staying around 11.10-11.3, I replaced it with a Denso OEM replacement. Vehicle is 04 RSX-s. KPro version 1.4

You may be editing the wrong cam angle fuel map. Check your datalog and see what cam angle you are at when you have the AF you are tryign to change, and then make sure you edit the proper fuel table for that cam angle.

I'm editing the 50 degree cam. I have also attempted to edit all tables.

I have also ran datalogs and have my tables following cam, high/low speed etc. and the portion under boost does lie under the 50 degree cam. I know to click on the datalog to find the correct portion to correct. I also know that it takes valued from an average of 4 cells and I adjust all of them.

The issue isn't in that I don't know what i'm doing, I wish it were because that would be an easy fix. I fear that my o2 might have failed already and isn't reading accurately under boost.

Some more information that might be pertinent. The stock O2 never fired a MIL I saw it was bad when I got tuned and it was reading like 13.8 while the dyno wideband was reading 12. Shortly after this the nose on my blower snapped off so I had to put the newer version on (comptech).

I noticed that the boost wasn't quite the same afterward my digital gauge with it's own map reads correct but the stock map is reading quite differently from it. (difference of about 1 -1.5 psi) I haven't wrung it all the way out in a proper gear to determine the difference of boost; once I find a nice road to bring 3rd gear to 8600 I'll know for sure.
