First E85 Experience, wow!

MadDog89 · 11-10-2019, 06:49 PM

I have a 2007 E92 with 97k miles, FBO, JB4, New NGK Plugs, New index 12 injectors, newish coils. I've been runing map 1 and 5 without any issues. I tried running map 2 once without E85 and got under boost code.

Today I went out and got 3 gal of E85 and 5 gal of 91 + whatever was left in the tank approx 3 gal. I am not sure if its just me but my car seemed a hell lot faster, went WOT and almost shit my pants. However I did get a misfire code in cylinder 6 at WOT

Other than that, the Demon in front of me couldn't pull away

You would benefit from running a backend flash with MHD with the use of ethanol and make sure to check your fuel pump pressures on JB4 to see that nothing is dropping below what it should be. Its ridiculous what our cars can do with a little extra octane

Nice! E85 always feels great.
It’s not just you, e85 is magic and those 3 gallons definitely made a difference.
So far I’ve gotten away with 6 gal of e85 and the rest 91 with no issues.
Next time I’ll try a 50/50 mix.
Put a dab of dielectric grease in you coil boots. Should prevent future misfires.

E85 is great stuff! Once you get a taste you'll be going for a 100% E85 setup in no time.

My nearest E85 is a full town over from me, I still run it regularly. lol

Don't run E85 on the stock backend flash.

I've read it can handle some E85? I haven't put in any yet but I've been tempted to.

Off topic, but looking at your sig I noticed you've ran a variety of ST sizes. I'm curious why you went with the 6266 this time around?

Shoot, I did not do the grease last time I changed my plugs. I'll make sure to do that this weekend.

That's what I was afraid of, I'll be hard to go back and nearnest station with e85 is about 20 min away

what do you mean by 100% E85 setup?
