Switching between ZFG tunes? Quick and easy?

[CornFarmer]

I just purchased the ZFG AO tune - if I want to buy the ZFG E50 tune as well is it easy to switch between the tunes? Can it be done in just a few minutes? There isn't a lot of E85 around me and the only times I would probably run a E50 are when I want to impress a buddy or have some fun.

What if I have 87 or 91 in, mix for E50, run half the tank that way then fill up again with 87 or 91 will the AO tune run fine? Basically I don't want to be telling my wife confusing directions for filling up the car.

The last thing I want is to be stranded somewhere because I can't get the tune switched back to AO.

Thanks.

Takes just a few minutes. I switch all the time.

So if I've been running the E50 and wife is going to take over and fill up in a day or two can I just switch back to AO and it will run fine?

Are you referring to auto octane when you say AO?

Yes

Yes

If I understand this correctly, if its auto octane you shouldn't need to worry about switching tunes right? Am I correct in saying that?

AO tunes do not include ethanol tunes.

Run the tank down pretty low then fill up with 93 or whatever and swap the tune.

What I'm asking is if I 90% of the time run the Auto Octane tune but I want to be able to switch to the E50 specific tune occasionally how easy is it to switch from the AO tune to the E50 tune? 60 seconds in the gas station parking lot after filling up with mixed fuel? Easy to do?

I thought 93 tunes allow up to e40 or something like that. I assumed AO would be the same. Could be completely wrong though.

I thought auto octane was only for 87-93 and not a mix of E. Adam would be the one I would take advice from on this question.

E85 isn't everywhere around here.

I believe it's E30 but the 93/E30 AUTO OCTANE tune appears to gain 50 ish HP where as the straight NON AO E50 is 100.

You can blend up to E30 on your AO tunes.
Your E50 tune should be between 40-60.
