I tried and wasnt able to get it to run clean... but it was also my very first time even opening up the UpRev software. Thats why I originally made the switch to E85, as a bandaid to water down my injectors since I wasnt able to get them to run clean. But I got hooked on it and never looked back.

I wouldnt be even remotely surprised if more experienced UpRev tuners have done it without a problem. Heck, I might even be able to if I tried again now.

I believe DM is running a 93 tune and finishing up his e85 tune so he can run either if ever required.
Jwillis, you can run multiple tunes, but if going to e85 I would just go all the way to make it easier. Though need to evaluate your e85 stations and plans with the car.

This is correct. I want to be able to run both. 93oct on huge injectors with a beefy fuel pump likely caused a bunch of my issues.

Well that sucks! Glad I asked, I just looked it up and there is only one E85 pump around here and it's a long ways from me!

dmhenderson · 09-25-2014, 05:02 PM

Bear in mind that E85 burns 2-3x faster than regular pump gas too (iirc) so you're gonna need to know where you can fill up at all times.

I wouldnt depend on the out-dated websites. I would ask locals who run it... they will know where it really is. At least around here, the websites show places having it that havent in a very long time, and do not list many of the places that do now.

JWillis72 · 09-25-2014, 05:15 PM

Ok I'll ask around, my tuner knows where several are but he's 1 1/2 hours from me.

Hmm... That also means I need place between me and the Florida tracks, this could be a problem because I travel through the middle of nowhere.

JWillis72 · 09-25-2014, 05:24 PM

This looks hopeful, I guess I need to start checking places out and see who really has it.

Well off-topic, but I am taking my race car to Philip Island tomorrow for a test day (been chasing a drive-line vibration for 2 meetings now) and my car uses 4 litres/lap (4.5km per lap), and the test plan for the day calls for 5 sessions of an out lap, 4 timed laps and an in lap, so I am expecting to use 80-100 litres, which is 5 20-litre tins (no E85 offered at the circuit fuel dump), so I understand your point precisely.

E85 is great for making good power and keeping the engine cool, but f4rk you use a lot of it !!!

There are a couple phone apps that are pretty accurate from what I've seen so far.

Yep. I'm driving around like that right now

If you need help getting the tune straightened out, Frank Hill (Hill's Garage) wrote my maps from scratch. He's a whiz with Uprev.

You will need two separate tune maps for E85 and 93oct. Your car will be extremely unhappy with you if you try to run the wrong gas with the wrong tune. How unhappy? I don't know but I certainly don't intend to find out. Wrong timing = really bad things happen. Uprev holds 5 maps so once you get it set up right you can just flip back and forth provided you completely drain the tank before you flip.

FlexFinder is the one I tested out. It was accurate for the 3 stations I visited.
I also have one just called Flex-Fuel that I haven't really played with yet.

I wish Gasbuddy would add E85 but oh well.

I have three now, 93, 93 with meth and one that only goes 60mph or 4000 rpm( I let my son take the car to prom).

I have put 93 in and driven on my e85 tune. I stayed out of boost because it would be too much timing and too rich, but just driving around mostly low throttle, other than the terrible smell of pump gas without cats, im not sure i could tell the difference.

So i guess that right there is my 1st person evidence that 1000cc are fine with 93 LOL, it was probably just something i was screwing up when first starting tuning.

Don't have that luxury with a supercharger. I mean, you could keep it really low but it's not like a turbo where you can just keep it completely out.

To be fair, it took Frank who is a wizard with Uprev almost a full week to get it right.
