Whathuh? Details on transmission Cy!!!

Why not 2 tunes?

Or do I just not understand E85?

That can be done, but you basically have to run the tank dry and then pump in 93/91 and change tunes. If you have half a tank of e85 and then throw in 93/91 you will need to have a tune for that blend also. Other option is to siphon out any left over fuel when he is in the dead zone for e85.

Ya I can always have different tunes for different fuels but it's unrealistic to dry out my fuel system and switch fuels while driving from cali to tx. Carrying extra fuel is the most realistic option.

Carrying extra fuel would probably be wise, plus this allows for errors on mapping if a station drops e85 all of a sudden.

Ohhhhhhh, ok.

What if you ran a tune for 91-93 octane? What would happen if the gas is even 50% E85, you should be ok, no? BUT when you go back to E85 you'd have to run it dry

And E85 isn't consistent to begin with, so do you tune rich every time because there is no flex fuel kit yet?

I think it's a very bad idea to run a certain fuel with another fuel's tune, even mixed. Normally they drain the fuel system before they put in a different fuel for a different tune. You don't want your car to "run" dry. I've done that on the track due to the stupid "dots" fuel gauge.

I agree to an extent.

If you have an A/F gauge, and the car wasnt tuned to the absolute brink of ignition timing... then you have a little margin to work with.

I constantly watch my A/F gauge so I will immediately notice if something goes wrong. I also dont have my ignition timing bumped to the very last degree of making power, so I know it has a couple degrees of wiggle room for less stable fuel.

So I suppose I would say that it depends on how "in-touch" you are with your tuning and monitoring it. If you are a set-it and forget-it guy and dont want to even think about it... than I agree just drain that tank and do a clean swap.
