Are the non flex-fuel trucks pre-wired for the fuel composition sensor? The tables are in the computer so I was thinking of finding the parts and doing the swap.

So YOUR the cause of my bread and groceries going up..... Uh huh...yep. I see how you are

I'd switch to a hot cam. The pollution level would be the same as burning ethanol.

I checked into this a little while ago... Your non-flex truck is not wired for flex... YOu need to run a wire from the Compostion sensor to the PCM (Pin 56 on the C1 connector), also your tune needs to be adjusted for the flex inputs, sensor tests, and fueling tables modified... Not to mention buying a few fuel lines and the composition sensor...

Well lets say I did run the wire to the PCM, is it something that can be set up through HPTuners? As I said I see in the engine setup a table for adjusting stoich ratio vs. alcohol content.
