switching between 93oct and e30 tunes

[Moddedblackbean]

Hey guys,
Ive tried looking up the answer but was unsuccessful, so I apologize in advance if this question has been asked to death. I currently have a 93tune on the car and I am looking to switch to an e30 tune as Ive heard so many good things about it. My only concern is that in my area, there are only a handful of e85 stations within a large radius of me, so what is the correct procedure if I am on the e30 tune and I find that I am too far from an e85 station but need to fill up? Do i need to carry the AP with me at all times so I can flash the car back to the 93tune if needed? Is it a map switch via the cruise control? Flash it back before or after the fill up? TIA for this noob

Your tuner can set it up so you 93 tune is slot one and E30 tune slot 2. You can switch on the fly I believe. Have to be careful not to switch to E30 on 93 though.

This is what I have. I switch after a few presses of the button.

Like stated above, it can be a risk having both 93 & E30 slotted adjacent to each other, some tuners will not do it. I keep them totally seperate and have to use the AP if i switch fuels.

That makes good sense, it sounds a lot safer that way to avoid a possible risk.

It's not a big deal, you can check which slot you are in at any time without changing them by pressing the Cruise button. I had 93 on slot 1, and ethanol in slot 2, so when I was running E30 I hit cruise, and the tach needle would jump to 2k RPM, whether I was idling, or driving.

Ive seen many a post of users who cannot figure out why their car is suddenly lacking in horsepower, and it was because they inadvertantly put the car in a "bad gas" tune slot and had been driving like that for a while. That is usually with daily driving. Doing something like autocross, I have inadvertanly changed radio stations, turned on windshield wipers, etc. I would hate to be giving it the beans and swap to a tune mid-run that could make things go kabluey.
