I’m not sure why you’re referencing the RS4 at all? He’s not talking about RS4s. He’s talking E85 as a fuel source, adn talking about its limits.
If they can do an E85 tune I would be all over that. That stuff is corn gold.
I have been pushing GIAC to make one, but havnt gotten much response or interest. Quite possible it could make more power than race gas.
Although at this point I think the bottle neck might be the amount of air we can force through the charger or valve train.
E85 isn’t bad but it’s not the greatest. If tuned properly you will quickly see just how fast you run through a tank.
I think jfonz needs someone to consult him on posting and getting with certain people. He might have a possible good product but if your associated with dirt bag fools like SRM and you have b5 guys jumping into threads to say how great you are that’s just not great. Also how bad are these guys math if they say they have been running this for a year. Isn’t that what they said last year. If after a year of running you don’t have any results and your just riding the hope that the B8 guys will be dumb enough to get fooled with dyno sheets you missed the mark. Jfonz himself seems smart enough to stay out of drama but the idiots he has around him continue to bring him down.
Why do guys get so wrapped up in the E85 craze? It really isn’t that great and can cause a world of headaches to be honest.
I’d be willing to bet that a straight E85 setup won’t do anything over a race tune running 104 or higher octane.
not your best moment
“I’d be all over letting a company that has gone bankrupt and disappeared and changed it’s name 3 times in 18 months, and who got their start stealing tunes from theftomoto tune my $50,000 car!”
all for what? For some fuel thirsty octane?
You need a bigger blower or a new car if you want to go faster.
You may be right I should have emphasized my enthusiasm with the e85 proposition moreso than the company advertising it, but, I would still love me some e85 tunes, hence my comments about pushing GIAC. What I have seen in my logs is that adding e85 to either the pump file with 80% or higher pump gas or the race tune with the same ratio, pretty much eliminates knock retard.
Race tune performance all year round, with cheap e85 gasoline, albeit crappier mpg, but I couldn’t care less about that. Not so much about going faster, but going as fast as possible, all year round. Conveniently.
There’s a reason forced induction cars on basically every other platform have a lot of e85 tunes.
…and all the fun of inconsistent blends, one week your car might run like a raped ape…and the next week not so much. I also doubt that running 100% E85 is possible without fueling upgrades.
I guess I just don’t understand wanting a car that needs race gas or E85 all the time to be “fast” or perform. I want to run pump gas 99.9% of the time and if I occasionally can run some race gas at a dragstrip day for fun, then that would be cool too.
It’s not, already been stated a HPFP is needed, and to each their own, I would like to have a car that can run at 99% of it’s performance capability all day everyday within reasonable safety limits. The difference between “street” and “race” tunes while not drastic is significant, more so than any NA application, and almost entirely due to timing sensitivity of this motor.
Adding an e85 tune to an RS4 would likely produce marginal to minimum gains, whereas adding it to the 3.0TFSI motor would produce “race” tune results more than likely. Which is most likely why RS4 guys could care less about e85.
Also, all things that safety measures programmed from the tuners can control. Yes I know it’s not an answer to inconsistent fuel, but so far my experience with e85 has been all positive, with very consistent results from multiple stations in my area.
This is a great write-up…
It shows both pro and cons
I see lists like this and see it as a huge hassle:
[quote]Some things that I have employed to counter the effects of moisture and there by corrosion is…
- Know your source. Find a staion with high turnaround
- Catch cans
- Alternate from E85 to 93, I do one tank of 93 to every three tanks of E85.
- Block Heater to prevent condensation.
- Frequent Oil Changes.

Then take into account the changes in blends, carrying around a test kit, or buying extra hardware like a good wideband.

S4 has two wideband sensors both of which can be accessed. Car is daily driver and never sits for more than 24 hours, tank is rarely below empty, one tank of 93 octane is hardly a hassle, already rocking a PCV bypass 
Highly doubt I have to change my oil more than the 4000-5000 mile intervals I do now.
I do AGREE with you though, NOT for everyone.
yeah, personally if I had to have ‘x level of performance’ aka trapping 118 mph type acceleration, I would buy another car that can do that on pump gas. For me the pump gas performance is really all that matters.
Of course that’s not the most practical decision, and if you love your existing car, makes even less sense.
The truth is Jones, everyone wants more.
If you have an RS4 that traps 108, you want an RS4 with tune and exhaust that traps 112
If you have an RS4 with tune and exhaust, you want one that adds lightweight rotating parts that traps 113
THen you want a JHM stage 1 supercharger so you can trap 118
Then you want a JHM stage 2 supercharger so you can trap 127
Then you want a JHM stage 3 supercharger so you can trap 135
If you have a B8 that traps 106 you want a tuned one that traps 110
Then you want a stage 2 one that traps 112
Then you want a stage 2 one with LW parts that traps 114
Then you want a stage 2 one with race gas that traps 118
Then you want a stage 2 one that traps 118 on the street so you want E85 or meth
Then you want a stage 3 one that traps 123
It never ends for anyone.
On the topic of E85, last time I checked it uses about 30% more fuel to run, so has anyone done the cost sensitivity analysis of E85 vs. race gas? That would be interesting. I would not at all enjoy E85 on an Audi with a 61 litre fuel tank. That would mean you’re filling up every 175 miles. That’s ridiculous.
Also, I thought 93 octane + meth on a 100 octane tune was working for you?
Jones I’m not trying to talk you out of this so don’t think that is my objective.
I’ve also thought about running E85 on some of my other cars in the past and the conversion/tuning/overall hassle wasn’t worth it to me.
I think if you love the car you should spend the money somewhere else, maybe have someone fab up a centrifugal blower kit.

Looks like a fellow local to me may jump on this tune… I sent him a PM letting him know I’d be more than willing to do some strip testing with vids for the forums this spring… Also, offered up any vag com mods he’d like… Will see what he says…
;D
if they could integrate a flex fuel sensor into this package i could see it being a very popular package that will make them stand out from the rest.
Except the fact that they haven’t provided data for any of their tunes…beyond a dyno.
Maybe they can stand out when they are a legit company and keep their name longer than 6 months. Until then anyone who experiments with them will likely end up like you (switching to someone who knows what they are doing) or worse.

ya your right, dont want anyone wasting their money like i did because i listened to people like you
;D
