I am noticing a difference between my main dash and my logging dash. For instance my main dash reads .676 (E85) via the flex fuel sensor for the fuel energy constant, however the logging dash reads .1xx for the same value at the same time. Has anyone else seen a similar thing. I contacted Fast about it and they let me know that it could be a corrupted gct file?????? The other thing that I notice is that when this happens the car spits and sputters.
