From what I've experienced in my old car and what other's have seen E85 gas reduces your fuel efficiency by 4-5mpg in daily driving applications. Even though it's cheaper by a considerable amount you'll send up paying just a little more (few hundred a year) compared to premium.

Correct on the gas mileage aspect, but more importantly for most people who want to run it, it adds power. E85 having a high octane rating, tuned, equals faster racecar.

How granular is the sliding "on the fly" tuning? Is there essentially no reason to run a 93 map any more? Will the tune for e85 accommodate anything from E10 up to E85 on the fly?

Also, for those asking about why not run e85 because it's cheaper, it also equals 30% less fuel economy. 30mpg on 93 becomes 20mpg on e85, roughly, so there's not really a $$ savings at all, just a big power enhancement with the cost per mile being roughly equivalent.

My SRT-4 is running an e85 tune, getting about 16mpg. Before, on my 93 tune, it was good for 22-24mpg.

Yeah, that's the point of Flexfuel, it covers from 93 to E85 in one single map

Very nice, I misread your post on the first page and thought you were describing this setup as having two maps.

Sounds great, true flexfuel capability, fantastic!

Is this going to to be a third map purchase option or is it a direct replacement for those who own both pumpgas and e85 (assuming they buy the kit?)

In other words, those who own both maps today, is this a free map replacing both? For those with only one, do they pay another 350? And those who have neither, is it 700 total for the flex map?

I realize the sensor kit itself will have an additional cost, I'm just asking about the map itself.

No third map

If you have my pump and e85 map all you need is my kit

Thanks, so those of us who only have pump or only have E85 right now, we'll pay another $350 to get the flex map, and however much the sensors cost?

Obviously this will increase reliability and help thwart some starting issues, which is fantastic itself.

I am curious though, given the flexibility of a precise content figure if you can afford to be less conservative with the tuning? Translated; any chance to see an increase in power numbers if using the kit?

I dont think there anymore more power to be had...

That being said if you ethanol content isn't 85% - lets say 75-80% you'll be down on power.

This kit will be able to compensate for the difference always giving you the best power

Since there will constantly be different ethanol contents in the gas tank how will we know how much power we are making at the moment, and can you adjust boost on the fly and have it be safe to more ethanol being utilized?

As ethanol content goes down the timing , boost and fueling will be adjusted.

Yeah it's safe
