afr readings?

[dkelectronics]

i have a 2010 camaro ss 6 speed ls3. my question is can i go by the afr readings off my log files for fuel adj. and how acurate are they? my afr reading at wot is between 11.2 and 11.7 from 2500 rpm to 6600 rpm. thats way rich for n/a car. my ltft are right around .078 to-.078

Not sure what kind of PIDS you see on your 2010 Camaro, but what I would do is invest in a real wideband like the Innovate MTX-L. That way you can see what it really reading on the guage and you can go by that instead...

I personally use an Innovate XD-16 with an LC 1 and a Trinity and I log my AFR that way and it works like a charm....

On a stock car its pretty close, but as knuckles mentioned, if you reeeealy want to know, you need a wideband.

don't worry about it man... cuz when you have me do the custom tune for it, whatever you set it to now will be thrown out the window when I get my hands on your tune files and re-do it all...
