E85 tune

Has anyone been tuned for 100% E85?
Ooook... I just did.

2011 EB E90 DCT
Gintani sport axel back

Wonderful E85


Thank you to Alex for the smooth tune and the crew at Gintani!

I've been driving the car now for the past couple hours and the car pulls hard and smooth!

Stock injectors and fuel pump?

If so, what are your injector duty cycles looking like?

Had a great time today on the Dyno with the car. I'm glad your happy we still have to make some tweaks real soon... 😜 Car feels amazing on E85 with very nice power gains!!!

P.S E85 tunes will be available soon trough our end user flash cables let us know if there is some interest... Next will be E85 setup for out S/C kits with full fuel system as and option...

Thank you
Alex

What's the baseline based off of mod wise? Was it the mods you listed plus a regular tune or completely stock?

Great results. It is amazing what can be done with more octane and a tune to take advantage of it. Is the tune a flex tune that can safely revert to pump gas, or will it then be relying on knock sensing to pull timing back from targets that are way too high for pump gas?

I thought e85 caused wear on the fuel lines or something if the car wasn't designed for it?

The baseline mods are all his bolt on parts listed with a complete factory tune... The car still has secondary cats in it...

Hi this is not a flex fuel tune sorry. The way it would be packaged when sold is, you will get 3 files OEM 240e, 91-93oct Tune and E85 Tune...

Hmmmmmmmmmmmm...the Procede will allow you to use 3 tunes, and this would be *perfect*. Once the initial tunes are programmed, no uploading of a file, simply pull back on the stalk to switch between them. You guys should check that out to offer tuning that way, as well. I have heard, however, that if you move to a full E85 tune, you should stay there and not switch back and forth between regular gas and E85.

What kind of timing targets do you guys hit with e85? Logging data on running e30 I have noticed when hot out, it still sometimes wont hit the targets on my regular tuned car with targets of 34 degrees in the upper revs. So I am curious with hot temps out, despite having unlimited octane (e85) don't the IAT's still limit the timing targets that can be reached. ie moves the target table to a different one with IAT's at a certain temp?

Also is this on straight e85? If so isn't this stressing the pump and injectors? Not to mention fuel economy! Geez on e30 I am getting 14 mpg with hard driving.

Last, could you guys offer an e40-50 tune? I think many of us would like to avoid stressing our fuel system with full e85 but would like to take advantage of some extra octane.

ALso what other factors are adjusted in an e85 tune besides timing?

That is a HUGE power delta. From looking at that baseline I'm guessing on a dynojet the e85 tune would be well over 400 RWHP.

I wouldn't run e85 everyday but if you wanted a little extra power every now and then it would be cool.

Nice job Gintani.

It's certainly easier and cheaper than running a dedicated water/meth system and tuning for it.

But it may do weird stuff to the fuel injectors so it shouldn't be run 100% of the time.

A lot of people are doing this on the 335 with good success.

Cheaper? Not if you need to do a fuel system! In Australia everyone that makes big power runs e85 I know heaps of people that run it all the time just need to clean the injectors after about a year not that I would do it because they don't sell it at many places here

I am not sure how it is making 40 more hp? Timing is not an infinite value where more and more is going to make power in a linear fashion. The 34 degrees on a regular tuned car or 32 OEM, is still a ton of timing. You can only start the burn so early especially in an engine revving to 8400.

I would be curious if gintani can comment in general how the power is made? I understand the cooling effect is probably pretty large with 100 e85.

Can we purchase this yet from you guys?

I wouldn't say it is either, as
a) we don't know what Gintani is charging for the tune, so we can't compare it to the cost of a meth system quite yet and
b) E85 gets worse mph than a meth tuned car, so given that, eventually there will be equilibrium, and thereafter, it'll be cheaper to run meth. I would be really interested in running both, just to see how much more power would be made as the meth helps keep the IAT cooler.

Given all of that, I'm glad that someone has finally stepped up to the plate and given the masses what we've been asking for. Hats off to the OP for taking the plunge.

Me coming from the boxer 4 subie world, E85 was my primary fuel of choice. That plus my dealings with Alex at Gintani since owing my M, I had to take the plunge. The future performance capabilities with E85 and the "products" Gintani has coming are very exciting.
