I drive a turbo'd 2006 Silverado WT 4.8L non flex fuel. I filled up with e85 last night, with only a few gallons of gasoline left in the tank, I drove for a few minutes to maybe get some of the gas outta the rails. Then uploaded a tune, I changed the values in all cells of the stoich table to 9.8 for e85. It started rough but I drove for a little while (10 miles maybe) and it stayed rich, and I had to take out 20% from the VE to get to lambda while driving. I ended up driving for over 40 minutes. The gas tune was pretty spot on. This morning the cold start was super lean, and just a little lean crusing, man am I confused, I thought all fueling would be adjusted to the change in stoich?
