I know right now there are no plans to have a flex fuel tune that adjusts based on E content. I know because I asked 613B6 who tunes my car. But he also said you never know with Eurodyne (which is very true)
I imagine if it happened it would be a decent way down the road.

MAP 1.5? Not sure that's a thing. I'm shopping now and fwiw I see MAP offers only Stg 1, Stg 2, E30 tunes.

Probably E30 then I guess as I saw the stock DP still on the car.

Interesting. I assume it would integrate with a flex fuel sensor as I don't see how it could determine that on it's own.

apparently it just adjusts the fuel trims according to what percentage of your gas tank has ethanol in it.
IE... tell it you have added e70 then tell it you have a gas tank with 25% e70 in it and it adjusts the fuel trims
or say e85 with 40% e85 and it adjusts the fuel trims according to that mixture

What about e90 at 40% jk I get how it works. Cause I gotta go back out in the heat and change some things

You still have to know what the pump is spitting out. Could be E70 or E85. So unless you know that then no point inputting inaccurate info. Now, if it can integrate with a sensor and automatically adjust itself (like I think UMs does) without my input at all, that's cool.

Wonder if by changing it would have any kind of negative effect on the way the current tune is

For me that's not a problem since my closet station is 1hr away so I fill a 55 gallon drum in my garage and test it everytime I draw some out

Badass! That’s a step closer to a true flex tune. I have an ethanol sensor that tells me my E content and has an analog out to output that to a computer or something like the ECU. I’m stoked for this!!

Confused on how the % of alternative fuel works, tank size is 13.2 gallons I run 40% e85, which is around 5 gallons, now when you try to do it on maestro I think it's in liters but on the % it only goes up to 1.992188, I'm confused

i think he didn't add the table correctly.
it is absolutely useful without a sensor because the long term trims and short term trims cap out at 32% or so. When you are running high e blends, it will throw a lean off idle code.
Even if you are blending 70% actually, setting it to 50% will GREATLY reduce positive trim values, if this is implemented as a global fuel adjustment.
Wide open throttle was never an issue since it i dead on target. This is more for part throttle and idle where long term trims were high and short term trims were frequently maxed on full E85 cars until they adapted over time.
