How much fuel needs to be added to my tune to run e-85? what else needs to be changed? I just moved and there are a bunch of stations near me that have e-85. I also don't drive the truck that much anymore so it would be cheaper to fill up with e-85. what do you guys think?

 

you didnt mention if you have an e-85 truck? the fuel systems are different and the tune is pretty different as well. i have been playing with it but, my truck is e-85.

 

Just change your injector size 22-25% and it will run like a top. You shouldn't need to tweak much. And yep its much cheaper than 93 octane around here. Leaving your truck sit for long periods of time.. with E85 I wouldn't recommend due to possible condensation issues. I use it and it works great for me. Just remember you can go pretty rich at WOT and should net you 5% more power than gas

 

he has 42# injectors. what is your duty cycle at now? i know for sure the injectors and fuel rail on my truck are alot different than gas trucks but, other than that i am unsure. the ecm on e85s have the capabilities to compensate for how much ethanol is in the tank so you dont always always have to run e85. i can send you a stock updated e85 os so, you can check it out if you want me to.
