i have a 5.3 4l80e swapped old body style truck with drive by cable. I am using a 3 bar map sensor, and this OS supports 3 bar SD enhancement. In such case, would it be simply as putting the flex fuel sensor in line the return line, wiring up the sensor, and pinning the blue connector for the signal the flex fuel generates and enabling the flex fuel capability in the file? Or do these OS do not support flex fuel sensors and just rely solely on the 'virtual flex fuel' sensor?
If I can use a flex fuel sensor then I guess my search is done.
Here is the .hpt file
