Ethanol in Fuel = GOOD for Performance?! FF#29

it can't be difficult to for a tuner to do that with the stock ECU, can it?

Just scanning their page, I would suspect a "tuner" who understands what the inputted data-points mean, should not have an issue.

That said, if the sensor fails (off specs), I'd like to know the expected outcome. I'm not familiar with MS, but if knocking is extreme, it would be nice for MS to deal with it effectively.

For people living in colder environments, this may not be advisable to use since atomization suffers; if you google "E85 cold start," this issue is discussed. I know OEMs have researched this topic, and I must assume they have implemented a means to overcome this issue. IIRC, some type of heating device.

All of those things are reasonably easy to account for and any quality tune should incorporate safety features. I sent an email to ARD. We'll see what Lucky says about the stock ECU combined with a flex sensor.

Yes?

I try to avoid any gas with any amount of Ethanol, but sometimes it's unavoidable.
I like to use pure gas. Here in Alberta, Co-op gas stations use only pure gas ( NO ETHANOL ) .
Here is a website that will let you know what stations in your area are selling pure gas, good for Canada and the USA.
