E85

[Livernois Motorsports]

To revitalize this thread a bit. It looks as if livernois is working on a flex fuel tune that needs no injectors and will take a mixed fuel tank. Sounds pretty interesting.

Thank you for the shoutout [MENTION=13850]Nazgul[/MENTION]! :cheers:

Sounds like something that wont be getting the performance gains like a regular e85 tune. Seems more like a oem flex fuel car tune, that merely allows your car to run on both fuels.

No, it will use the unlocked ethanol content tables used for stoich and timing, and average out the actual settings based on ethanol content.

So for instance, you have half 93 and half E85. Your E85 timing is set to X, and 93 is set to Y, it will average out, and be somewhere in between until it sees 100% of either fuel type. Same with stoich. This is how it works from the factory F150.

But if you are going to run full E85 and not a mix, you're going to need injectors.

Not true. We have run E85 without issue.

At the same timing levels you can achieve with larger injectors, and full bolt ons? Or are you cutting timing so you don't have to fuel as much and limiting to just the tune/e85?

Livernois indicated in their other thread that the current fueling system for the coyote is capable of supporting the extra flow. Injectors included.

I just wonder why every other tuner requires an injector upgrade to run E85, and they don't. That's all. The injectors will be a limiting factor at some point.

I would guess that other tuners require it due to their method of tuning. Livernois has its own proprietary tuning software. Maybe their extra access to tables allows more fine tuning for such things as e85.

Even if their e85 tune was only 85% of what others offer I would take it. Not having to spend the extra cash on the injectors and work to replace them is worth it alone. (for me)

Considering they are a reliable company I doubt they would cut corners when it comes to replacing injectors. Everything they do is for a safe motor.

You trying to take my job!?!:lol:

Haha no. I've been nothing but happy with your tune and the customer service I've received. I did the same for APR when I tuned my Volkswagen/audis. I have no shame in name dropping and supporting a company iI trust.

No matter what tuning you do, there's only so much the injectors can flow. They will always be the limiting factor at some point. That's not proprietary. I'm not saying they're cutting corners, I'd just like to know the differences in tunes. I don't want proprietary info on how they're having the tune self adjust/etc, I'd just like to know if they limit timing advance, other modifications, etc when running 100% E85.

I agree that the injector has only so much physical capability. I would argue that there are ways to tune around those limitations though. I've seen it with tunes for other vehicle companies, vw/audi mostly. It use to be common place to replace injectors for upgraded turbos. Years later that mentality has changed somewhat and companies tune around it making similar results. Apple to oranges I know, but if it can be done with other cars and fueling systems it could likely apply to our motors.
