Becuase flex fuel is the best mod ever to any high power turbo car that's gets driven a good amount on the street. Amagine a built evo make 700+whp. This can only be done on e85 the same car probable only makes 450whp on 91 octane. E85 station are rare here in so cal plus e85 only nets about 13 mpg and about 150 miles per tank. You cannot confertably drive this e85 evo because you will always be in fear of running out of e85. If it was flex fuel you can just fill the take with 91 octane and the ethonol content will drop and the ecu will automatically drop timing and drop boost depending on ethonol content.
This is simply is the best mod for a built high horsepower turbo car that make 200-400 more hp on e85 compared to 91octane.
The question is, will tuners make linear or nonlinear interpolation maps between base and alt1 maps... and how to address the 1, 2, 3, 4 transfer functions. The flex part could put a lot more work on the tuner since who's gonna dyno all the intermediate ratios. Or they tune the two extremes and send you on your way.
spoke with ralph, for a minute says its about $1000 for the work, if you are already running e85. if your just 91 you will need to buy all the stuff you would need for e85 along with the $1000 for the new flex system. there is and android app that reads this data Via Bluetooth connector guessing thought the ECU port.
ralph was confident, and said they ran things out, even unplugged the sensor while the engine was running.
this is something we all have wanted, I think I'm gonna guinea pig and get it done. but the rule is my have to buy my wife something of equal or greater value lol.....
Did you see this video? https://www.youtube.com/watch?v=xjPZbwfItVQ He goes through this, with the AEM anyway. There is a blend table, default is linear, but the interpolation is variable. I'm not sure how the Evo X software is setup though, but i can't imagine it being all that different.
It's somewhat similar. This is an example.

We've done 5 Flex Fuel Evo X so far all with 0 issues MR and GSR all tuned with varing levels of corn in the hole
E10 initially
then i drain it
and add enough for E35 and dial that then E60 then E75-80 is where i end up
Not my first flex fuel rodeo

Perhaps a nonlinear approach is in order
I know it's available at 5150racing now and it's runs good
No I hear you man I was a loyal person to mike as well. But as time has gone on with rre. Seems like Rick thinks he is the shit and instead of listing to customers he tells ppl what to do. Lol yea I trust 5150 now more then rre. And they seem to know there stuff alittle better then rre for them being in the game not as long they have sure impressed me.
I drove from SD to get this done, it works. just to fuck with it, when I got home, I put $18 bucks of e85 and $12 of 91, on what was left of 64.4E tank and got 71.3%E. drove it another 15 miles. I plan to do my next refuel all e85 though, then maybe back to 91 just to put it thought its paces.
the Bluetooth app changes in real time, its takes minute to settle on a number. the only thing i don't like is you don't get a lot of printed data, I got a graph with the 91 and E tunes on it. and stickers i asked for.
they should change their name from 5150 to area 51.
my poor evo was worked like a $10 hooker today. spent hours on the dyno, then spent 3 hours in traffic on the way home, then a few pulls from me, for the street this is more then enough.
