Is it worth doing E85 kit

Facts. That’s the crappy part. Especially when you have none available and your house is your only gas station option. Makes it challenging to enjoy it or make it worth while.

Even worse, the two stations in my town that have e85 pumps, only have one e85 pump, and it's always being taken by someone getting normal gas or just have their car parked there taking up space. Then you get to sit around for ten minutes while they are inside playing lottery tickets and shit

Did anyone ever post what the ECU advances timing to when using the kit?

The Pro Flex kit does not advance timing. The ProFlex Commander works by digitally intercepting and augmenting the fuel injector signal from your vehicle's stock ECU. It modifies the injector pulse width to inject more fuel when E85 is detected, compensating for the fact that ethanol requires a richer air-fuel mixture than standard gasoline.
I've run the kit since 2018 as probably one of the few in the country at the time for GT350's after much discussion directly with Advanced Fuel Dynamics. I now run a Wengerd flex tune with the Pro flex commander which acts as a real time ethanol sensor directly at the injector pre combustion. All e85 and flex tunes infer the ethanol content based on the O2 sensor post combustion. I ran the kit for six years prior to putting any type of tune on my car.

I have an e85 tune for mine, I know not a gt 350, It does improve power everywhere but the loss in driving range made me put the 93 tune back in. Drops down to about 150 miles if I remember correctly. Seemed like I was hunting a fuel stop every other day.

Even worse than that, the local pump I do have is not great and even that changes seasonal. I’ve tested the pump as low as 65ish. No go for me.

it’s been well established that you don’t need that much ethanol to get the benefits. 65 is plenty, especially na. Before tuning was available, the supercharged s650 guys were able to hit mbt with only e40.

Except for the fact I have a 85R tune and was told by Wengerd to not run anything below 75, minimum. Yes, I asked for that; that’s on me. We set my tune up with 85R that tested at 90. Maybe 65 is plenty for me. Maybe not. Not going there either way.

I believe oem calibrator Greg Banish, research publications on the matter, and my own personal experience over any popular coyote tuner. Unless you need over about 130 octane, which you don’t, e60 is plenty. But it’s your car and your decision. I just wanted you to know you’re unnecessarily missing out.

this…times eleventy. Had a Lund e85 tune for almost five years and used it exactly twice

I have never seen an actual Wengerd tune so this may not apply;

If it will knock with with fuel below E70, the ign timing is over advanced.

There is a thing called MBT, too much timing and the engine fights itself.
If it will knock on E60 It is 99% over advanced, or the tuner (generic not Wengerd specific) wants you to think you have a special tune and sets the timing correctly.
