How To Run Full E85 in Your Audi S6 

Can’t wait till you surpass the 100k mark with subscribers. Def underrated my man

Been watching your channel for the last couple years and playing catch up, but had an S4 MT, traded it in (regrettably), then sold the care I traded it in for because of Covid, test drove an S6 and really liked it, but can't get past not having a MT in my car. I feel its a way of life. I wish Audi dropped an MT in S6 because it would be a no brainer per the stock performance and additional luxury. When I test drove the S6 as driving any other car I am occasionally reminded that as I reach for the mysterious stick that doesn't move or the non-existent clutch on the floor boards that this isn't enough for me. Enjoy your vids, but missing seeing the S4 (I think it was involved in an accident). Anyway, I am seeking financing for another S4 MT I found with 50k miles now that I will be getting back to the office here and there and the drive is longer and requires a more comfortable ride than my 09 R56 that is also on its last leg with blue smoke syndrome. Anyway, keep up the entertaining vids.

I’m a 4th year dental student. And I feel you man. Being a patient is no fun. I love what I do, I do feel bad for the thing that patients have to go thru. Been here since the Mk5 days.

I don't have an S6 but this is still fun to know. In other markets my Saab had a factory Biopower option that consisted of an ECU tune, engine block heater, and a few other tweaks to run ethanol. It's possible for me to do something similar here on the aftermarket quite reliably, so I may do that. Good to know about the various blends though, that's something I'll need to look out for.

Cars coming along great. Love the look and sound. Ready to watch that track vid too. Great stuff.

It worked got a Sub

So pretty much what you’re saying to avoid all the issues of re flashing, re fueling, having the car run rough, afraid of going past half throttle etc etc etc.. just get a tune with SRM flex fuel and I don’t have to worry about anything. Gotcha

Nice

love the vid bro. just picked up an A6, can't wait to make it my own

Hi Eli, when you are talking MPGs are you using what's displayed on the dash or are you calculating when you refuel? I found the MPGs on the dash are very inaccurate. I had it show 19mpg and when I filled up got 14 mpg actual.

Mmmmm think this might be my next car

You're driving the car i wanted but i had to settle for the b9 s5 wich i love, it is tune on stage 1 93 but i want to try the e85 file and see the difference

Hey Eli, Hope all's well with you and the fam. I sold my blue SQ5 and picked up a '17 A8L 4.0T so i'm back tracking your vids a bit. Just threw a bunch of goodies from SRM on there. DS1, RS7 turbos, inlets, HPFP/lines. My problem is when I fill the tank with corn and floor it (afrer it warms up) I can feel power just clipping. SRM sells a kit to make it fully E85 compatible (LPFP, module etc) Just wondering your thoughts on that. I'm hunting for 9"s. Thanks for the content, you're a solid RU-vidr

What is the recommended octane level for your s6 by Audi ?

Shop put mid grade fuel to fill tank. I filled it back to a full tank from half But I wanna be sure and add octane booster either the Royal purple or stp Would you recommend a gallon of e85 instead?

Does the fuel system need any upgrades to run e85?

If i get the IE stage1 tune will audi work on my car if i needed them to

I have a s6 I'm in Canada Ontario the only fuel I can get here is e89 from vp racing is that ok to run and do you have to mix it thxs

I have a c7 s7. Is the e85 tune only applicable to c7.5 ?

Did you upgrade the fuel pumps?

I fn love my dentist. Been seeing him 22 years

Could I run e85 on an rs5

Ethanol in CA is 85% and 100-105 Octane and is only $3.79 a gallon

I'm curious about the actual % Ethanol level you're running (I see 70% in that table), because I was told the S6 doesn't have enough injector volume to run straight E85 without running lean. I was told with my new DS1 system that I should mix 92 and E85 to come in around E50-E55. Silly Rabbit Motorsports and Quicker Racing Components are both offering a fuel pump upgrade (new low pressure pump in the tank combined with upgraded high pressure pumps up front) and additional injectors to deliver more Ethanol, but I heard that the limit is still around E65-E70. BTW, my new RS7 turbos are performing almost as well on the base 91 octane tune as my stock turbos did with the APR Stage I tune on 100 octane. Time to turn it up with E50-E55, see what it can do, and then find a reputable DS1 tuner to maximize the gains.

Hey Eli, been watching for a while and I’m getting the IE tune for my S6 next week. I have been interested in the E85 tune that it comes with but kept getting conflicting info. Just to totally confirm with you, there is nothing required beyond the tune to run E85 in the car like a flex fuel sensor or anything? Just flash, fill, and go?

Are you getting longer crank times when running straight e85? After running ie tune in full e85 and a cold start it seems to always crank longer.

So a tune but no new hardware? You don't need pumps, injectors or take into account materials compatibility in the fuel system?

Hey bro bad ass ride but I’m looking for those rims but can Sean to locate the can you send me the website where bought them?

Can you daily the e85 tune or would you need to upgrade fuel system stuff?

so much work dont they have a flex fuel kit

The ie tune says to connect to a battery charger while tuning, does switching to e85 tune take less time so battery charger not needed or should you be using like a portable charger

What does your waste gate duty cycle % look like during a pull with E85?

Stuck between s7 or rs7

You should just get a DS1.

I'm sold on the IE tune for my C7.5 - should I wait until I've removed the oil screen or just go ahead and throw caution to the wind?

I want to go E85 on 14 Audi but so nervous too

I got 2 years left in college. I was thinking about getting an s6 after but I think imma go the 340i route

What’s the price deference for the E85?

I HATE THE DENTIST. I always feel better after I go though.
