AEM wideband & my car's 02 sensors not jiving after tuning...
VE tuned, MAF calibrated, & RAF tables tuned.
I mentioned in an earlier post that I had a lean CL idle after tuning. Well, after some more logging today, I realized that my WB reads consistently lean everywhere in closed loop.
I'm pretty sure either my WB or my car's NB 02 sensor's are the culprit. Most likely my WB I'm guessing. I'm using an AEM Uego with a dash gauge & input into HP Tuners. I calibrated the HPT input to the dash gauge & they are dead on with each other.
I logged a good long drive today after resetting my fuel trims. My wideband starts off at 14.63, but reads 15.1 consistently throughout every cell after my ltft's all settle at small negative #'s everywhere.
So, basically my WB is reading 15.1 when the NB's are reporting 14.63 as far as I can figure.
Any ideas other than bad readings somewhere???
