So I believe that I have a bad flex fuel sensor as my commanded afr is around 12.2 when warm and operating in closed loop. My Alcohol percent is stuck at 43% and the sensor was putting out a 92 hz signal (read it with a tech 2). I tried to disable the sensor using HPTuners by setting the master flex fuel to disable. The tech 2 now said the sensor was putting out 0 hz, but hptuners and the tech 2 both still say 43% ethanol content and my commanded afr is still in the 12`s in closed loop. I finally got pissed and reset my stoich AFR to 14.24 across the entire alcohol range, now the commanded afr goes to 14.24 at operating temp. I thought the point of the master enable/disable switch was to be able to use it to turn off flex fuel, so why did I also have to figuratively zero my stoich table also? I attached a starting file and the file from after I disabled the flex fuel sensor AND zeroed the stoich table. The log file is from after I disabled the master flex fuel switch but before I zeroed the stoich table.
