E-85 Conversion

[vatman02]

I have an 05 GMC Sierra. According to the Predator Programmer web page, most of the newer GM truck lines are equipped to run as flex fuel vehicles, you only to activate the "dormant" parts, ie. the fuel sensor. Can we do this. I can't find anything to turn on the sensor. There is a pid for logging GME85PCT, but when i log it it only shows 0.

here is the quote " will allow 03-07 GM trucks to run E-85 in their stock vehicle without having to purchase expensive conversion kits. This tuner modifies stock PCM programming to allow components that already lie dormant in these trucks to pick up and use ethanol in the fuel line. In the old days, this would been impossible due to the use of organic rubber in vehicle fuel lines, but for the last 10 years GM has been including synthetic fuel lines and ethanol sensors in these vehicles STOCK! Run E-85, Support America!
