i was wondering if the sct tuner can be programed to run e85? the gas station near my house sells it for 20-30 cents cheaper than regular!
ive heard some vehicles pcm can adjust to run on it but not that well 3-4 mpg less,
sorry for the random question but i was just wondering

 

Its not so much the PCM from my understanding, its whether the truck's engine/fuel system can handle it well.

E85 is cheaper per gallon, but ends up costing you more overall due to the lower MPGs. There have also been many reports (much disputed) that E85 will eventually eat away at your fuel system's seals and any part not metallic, because the system is not designed to run it.

Ethanol has a higher octane than gasoline, so many uninformed people say your engine should run better on it. What you have to figure out is that ethanol has a higher octane only at a higher compression ratio than most modern engines use. If you run a turbocharger or supercharger, for example, E85 will benefit you more than on a naturally aspirated engine.

You can ask Sean about it if you want, but I doubt the PCM can help you out much.

 

You are correct. If your car/truck doesn't have Flex fuel capabilities you can't run E85.

 

That would be a question for hemifever but I know you wont want to spend the money to get your truck ready to run it, all the hose and seals would need to be replaced, and you may only save a couple pennies at a time, not worth it IMO

 

thats pretty much what i thought but i thought id ask yall first

 

Found an e85 conversion kit.

Here is some info about running e85 in a non e85 vehicle.

That site lost all credibility when I read "myth" #4 and #11. Some of that may be true about our seals and fuel lines being more robust than they used to be, but claiming E85 will increase power is a half-truth. They are there to sell their product, nothing more.

$450. Yikes.

 

im running 93 gas with the sct and notice my milage goes up 3-4 MPG. you really dont need much gas to get her moving anymore.

plus the engine is cleaner running higher grade gas
