What would the effects be commanding a Gasoline AFR if the vehicle runs on E85? Will it run? Does the PCM adjust the AFR automatically (I'm assuming so) and if it does will leaning it out under cruise conditions by tuning the Shown Gasoline AFR have the same affect if its running on E85?

Anyone? Does anyone know how the PCM revises the tune to run on E85? There has to be more inside the brain box than a timing table.

I'd really be interested in seeing this as well.. I want to run my Typhoon on E85 when its running the benefits are too good to pass up. I dont know how much support we are gonna get tho as E85 is only regional at this point and I seriously doubt its overseas.

I was told there was an octane switch somewhere inline in the fuel sytem however that I havent done a whole lot of research on yet. I do have some websites if you are interested I can send them to you. Not sure how much help they will be for tuning (ie, read NONE) but background info on E85.
