E30 30% Ethanol Who's running it? Flex Fuel Lite...

I've done some looking and I cannot find anywhere on the forums. I know E30 isn't available everywhere but I live in South Dakota (corn's home town) where almost every gas station has yellow handles and most of the ones who have E85 Also have E30.

So since I can't find it is anyone running E30 in there cars?

Some Reasons why E30 would be better than E85.

1) E30 is always 30% Ethanol Year round it never changes so your tune doesn't need to account for E85 which may be 61% 73% or 85% depending on the pump or time of year.

2) E30 is 95 octane, Look it up if you don't believe me.

3) E30 won't nuke your fuel economy. In another car I own. Details below my fuel economy only dropped 11% total.

4) Significantly easier to meet emissions. A 30% blend is where you start to see your exhaust gasses become much more clean.

5) Cooler engine temps - not as good as E85 but once again on the car below I seen oil temps on the interstate during hot days drop by 15 degrees.

6) I have a 2006 SRT8 Magnum with the 6.1 which has pretty high compression for a pushrod V8 without variable cam timing, and using HP Tuners I rescaled what the computer thinks is stoichiometric and run it on E30. With this Setup I also spray 120 HP worth of nitrous in the car what's pretty close to the stock engine timing (Lower RPM's actually are a degree or so advanced). I do this and still don't pull more than 0.8 volts on my Knock Sensors.

I'm still attempting to figure out this openflash romraider tuning thing on my 86 to set up an E30 Tune. I see a lot of people scaling injectors. I was wondering some slight injector scaling mixed with opening up the fuel learning if the car could be set up to run between 15% and 30% ethanol Blend with Premium without having to re-tune the car?

FYI I have a 2017 Toyota 86.

Yes you could make a dedicated E30 tune.


As well as fueling you mght as well add some ignition timing to take advantage of the higher octane rating.


You could likely run E30 without a tune but you would have high positiove fuel trims about 15% and you wouldnt be taking advantage of higher octane rating

This would be great, Cause E30 Costs $2.10 and 91 octane premium costs about $2.80. For a daily driver I want good power but I want it safely as possible and squeezing out every last little bit isn't my top concern as much as getting good improvements and reliability...

What's the saying There's Powerful Cheap and Reliable pick any two....
