so you probably need to increase scalar value to run higher % of E85 in order to not max out fuel trims

Last I checked they only sell to FF approved vehicles.

E30 and log, there may be some room for more timing in your case

I think you need to stop quoting this online calculator! There is ONE MAJOR error in it: it assumes that the octane rating of E85 is 105. This is the RON rating and it can be very misleading since the gasolene in the USA is rated using AKI (Anti Knock Index). So, just to be clear here: E85 has AKI index of 94-96. Premuim gasolene has AKI rating of 91-93 depending on the state you get it. That number is written on the pump! DO NOT confuse RON ratings with AKI ratings when you are blending fuels! EDIT: To get 14 gallons of E30, one needs to blend 4 gallons of E85 and 10 gallons of AKI 93 fuel. This will end up achieving 14 gallons of E31 and the AKI rating would be 93.3 which is just 0.3 bump in AKI from what you normally get out of the pump

Again this is just based off my butt dyno. I'll take it to the dragstrip when it cools down a bit and do a comparison between the old v301 Stage 2+ which netted me a 12.3@117mph in the 1/4 mile and this new v402 E30 map. Don't get me wrong, the car is definitely faster especially up top.

No idea honestly, but people must be careful.

So the mixture for E85 (depending on gas) would be about 4 gallons e85 and the rest 93.
Anybody know what the calculation for MS109 race gas would be? How does the race map compare to E85 map in terms of power? |

PTF (pro tuning freaks) are on this forum. Jake and Dzenno do an amazing job customizing the tune to your mods and octane and on my car with just an intake and dps even with pump gas they pulled off considerably more power and response out of the car. I was really impressed.

C16 may be a bit of an exaggeration, but E85 works very well in a mixture. Much better than what's implied above in this thread. Try it with an aggressive map and log, your butt dyno and your logs will both be happy. And that's all that matters... |

Yes, E85 has additional benefits when it comes to cooling the combustion chamber, but technically, that's different than anti-knock index. Plain and simple: USA 91 fuel = 91 AKI USA 93 fuel = 93 AKI USA E85 = 94-96 AKI PURE ETHANOL = 99.15 AKI Source: http://en.wikipedia.org/wiki/Octane_rating Do not confuse E85 and pure ethanol. Totally different things. EDIT: Take a look here: http://en.wikipedia.org/wiki/E85 Second paragraph in Octane and Performance Section: Quote:
