I am brand new to HP Tuners and OBDII tuning. I just purchased my HP Tuners and am scanning to ensure all is well with the engine before adjusting anything. I was driving down interstate into about 30 mph head wind and attached is the log file. Looking at the STFT it appears that my O2 sensor is dead. Am I reading this correct? Scanning my 05 8100 the STFT is constantly changing. Am I on the right track?
I have a new upstream O2 to go in, just need my wife to actually stay home long enough to work on it.
Otherwise I am going to tune it for extreme fuel milage once all the sensors are reading correctly.
Thank you all for the information
Corey
