I just wanted to make sure that the E85 settings on the CTSV OS Work. Before I spend the money on the flex fuel sensor. I know Ive seen posts about it before and people have had a lot of problems but they were never clear about if they actually got it to work or not.
Its not as simple as flipping the switch with a P59, they need a segment swap from a flex fuel vehicle of the same OS (flex avalanche or tahoe should work for your OS) or user defined parameters.
