Hi All,
Well got my wideband in and done a OLSD tune and used auto VE etc. Then corrected and applied it and also for DD re-enabled DFCO.
My question is that my AFR at idel fluctuates, so when starting from cold when commanding about 14.2 the WB reads 15.2, i know the VE is correct as when driving it is pegged at 14.6-14.7 mostly and BEN are around 1. Whan seems to happen is that when driving for a while the idle then is richer than commanded so now commanding 14.63 and runnig 14.0 ish +/-0.2, but then after I drive a bit more and stop again it might be 15.0??
I dont understand this fluctuation, I have logs I can post and my tune, but I dont even know why it would run commanded, then leaner, then richer all at idle??
will post logs at when home
thanks
