Where did I go wrong (WB O2)

[FarShot83]

I have been working on this for a while.
Searched for hours and tried to fix it with no luck.

Please look through my files and let me know what I did wrong.

Only running one NB O2 and the WB O2.
No MAF (not fully tuned out yet)
No EGR (using for WB O2 - pin 55 egr valve position)
Checked Ground offset as well. ( .04 difference)

Everything I'v done gives me the same results.
Maybe I calibrated it wrong...
Maybe I didnt' program it through LM Programmer v3.31 right...
Past frustrated...

Please point me in the right direction, advice...link...

How can it give me a higher than 20.9 while its running?

nobody can see your custom pid's unless you also post your vcmscanner.cfg file.did you by chance read this thread ?http://www.hptuners.com/forum/showth...&highlight=egr

Thanks for the reply but I posted 3 files and 2 pics...Basic Config.cfg. let me know if you can't see or load it.
I read that thread multiple times along with many others.

My wideband formula through the EGR is ([PID.2811]/.5)+10 and I've tried many similar while changing the LC-1 programming to match.
my ground offset is .03
I recalibrated the sensor and sensor heater. dead on 20.9 (I'm at 7350 feet altitude)

As soon as I start the vehicle it shows an AFR of 23:1+ and 4.97 volts at the EGR position PID in the table. While using logworks software through the computer it shows an AFR 28:1+ but Im using a serial adapter so that may be why its off so much in logworks. The ERG wire while its running shows 5 volts exactly with no change.

I see the three files. but your custom pid's are in the vcmscanner.cfg file that you did not post. look in documents/hptuner/settings/vcmscanner.cfg.doesn't matter now that you posted the pid.you may actually be running lean enough to max out the wb at 5 volts. as a way to confirm,decrease your injector flow rate by 15% and see what that does to the wb output.

I did as you suggested and it did drop. Should have thought of that. Thank you. On a stock tune for a 2001 silverado it shouldnt be that high. Ill find the source though and post a solution so its here if needed. Thanks.
