Yes, Just the IFR Table to switch between blends of fuels.. Right now I'm just "play tuning" learning the different ends and outs.. Mostly just on my drive back and forth to work.. I know with the same cal in the car and the same fuel it was a lot richer this morning (70degF) then it was on the way home last night (87degF). That's with Engine Upstream 02 unplugged and running the wideband.
