Sure Peder, I will check with them.. Thanks

The big difference was when jake at PTF sent me my first e-30 map the third 3rd gear pull I did the car just moved through the rpm's like butter. I was so thrilled that I didn't realize I was going 100 mph.
I will go with what PTF suggests when i meet them, i'll double check with CObb as well... This is so much fun and waiting for the day..

My guess is that Cobb is similar as this is a matter of physics, not software. E85 is much denser and heavier to move than regular gasoline. This is why people replace the stock LPFP with a high output Walbro when they go to higher mixtures or larger turbos.

I actually now have Cobb as well and use it to manage fuel, whereas the rest of the tuning management is done by a stacked JB4 race map. The difference is that I can now run the engine further up the rev band without dropping in power. The pulls are stronger up top, north of 5,500 rpms, due to the Cobb fuel management. Best of both worlds I guess. I am on about 40% E85 and 93 with FBO and 70% meth. Boost target is 18.5 psi, so with up to 1.5 psi overboost allowance I hit 20 at times.

So Peder you go with almost 11 gallons 93 octane and the rest E85? How do you judge these when filling, or is it 3/4 (93 octance) and 1/4(E85)?

Depends a bit on how much ethanol is in the 93 oct that you use. If it already has 10% ethanol (e-10) in it then you would mix 5 gallons of e-85 and 13.5 gallons of 93 oct to get a e-30 blend. The very first tank I did I ran the tank almost empty (don't do this too often) and then made my mix, ethanol first and the rest gas. After that i usually fill up at the half tank mark with 2.25 gal e-85 and 6 gal of 91 oct. Even though our tank capacity is 18.5 gal the half way mark isn't really 9.5 gal but a little less. Guess there is a reserve amount of gas that they factor into the gauge. I use this site to help me with the calculations. http://www.intercepteft.com/calc.html
If someone has an easier method I'm all ears.

Thank you Booyanazaa.. You are right i have noticed that the mpg shows differently on both half of the tank..

Appreciate your detailed explanation.. I'll consider these factors when i start mixing the E85.
