Ltft+Stft (%) trouble/ tuning tips
Could someone take a look at this tune and scan file. I had someone previously tune this motor and was told to keep driving around to log Ltft+Stft (%) to dial in my VE table. I dont have a dyno nearby so i have been doing what I can on a closed street. I have a couple concerns with what my Ltft+stft (%) graph is showing, it seems to be all over the place. However, my AFR gauge (not logging on HP) has been showing a consistent 9.2-9.7 range. Tonight was the first time I could drive the car home and i thought it did fairly well. The car did stall once, I am assuming that's due to the VE table not being 100% right. I also have noticed when I turn my fans on, turn my lights on, or draw any power on the car, the car seems to go rich. I would think this would be in my offset vs volts vs VAC tab? Not sure how to go about that one. Tuner has kind of gone AWOL on me as well so hoping to get some answers or be pointed in the right direction here. Thanks
