Livernois Mycalibrator Tune Claims 50HP Gains (on E85) for V6 JL Wrangler

I called them about it and it would have to be a PCM for the same year and model of Jeep. They would still need your original PCM to clone it if it was compatible.

The 3.6 can run E85?

any chance something like this could be used to increase mpg? I’m looking to try and get my ranger higher.

Not a chance it would increase economy. Ethanol has significantly less btu/gallon than gas. Conventional E10 will cost you a couple mpg’s over straight gas.

If you want range, stick with petrol. I've been running E85 for the past 6+ months here in Colorado. I live at 7k' MSL and routinely drive up high to 10k' MSL but really like the improved performance from the E85 tune. I've lost ~2mpg on the ethanol due to its significantly lower energy density.

The loss in power due to altitude is quite dramatic, and I'm running 35's with 4.88 gearing. The E85 performance up high with the correct tune is a very noticeable improvement, and E85 is ~$1/gal cheaper at most K&Gs in Colorado.

For commuting and local ski trips and trail rides (Frisco has a K&G with E85 close to Keystone & Breck), I'll stick with E85, but for overlanding and long road trips I'll switch back to 91. That's the beauty of the Livernois tune, I can make the tune swap very quickly and easily. YMMV.

@Tread4Lo
did you ever get an answer to your question? I would be interested in that PCM if it can be sold and re-used. Maybe send them an email direct?

I sold my Jeep and have my Livernois pcm for sale. You can use it on other Jeeps but need to have it coded to your vin by them. I spoke to Chris as I was going to reuse it in my Gladiator but the 2022 has a new pcm.

I ran E85 for a year untill the price's got too high. If E85 is at least 15% less than 87 you will save. It was actually 12% when I did the math but I figure 15% to be safe.

@Livernois Motorsports Random question for the Livernois handheld tuner. I am selling my Jeep with 3.6, can I sell my tuner? It's still married to my Jeep as the "stock" tune on the tuner will start the engine and work, but the CEL stays on constantly I assume to the unlocked PCM. Therefore Livernois had the write a stocklike tune to get it to work.

If not, I guess I am out the money and can't sell it. It would go in the trash can.

Same question here… I am selling my 2018 and getting a 2022. I would like to deal with Livernois again, but it would be nice if I didn’t have to spend so much. Maybe it’s time to really spend some greenback and go for that supercharger… again haha

See my post two up from yours.

Yeah.. I read on Magnuson’s page the other day that they went to the GPEC5 ECU mid-2021 model year due to shortages of the previous GPEC2A… I am thinking that when (hopefully not ‘if’) the new ECU is cracked, Livernois will probably use the same programming unit.

 

[VerservJL]

It sounded like they plan to use the same programmer once the figure out the new pcm.

So your 2018 tuned pcm is for sale?

Sorry to kick up an old thread, but I have been reading through this post and giving some thought to trying the Livernois Tuner. Sounds very cool. My situation: 2-door 2018 JLR, 3.6, Manual. Recently put 20x10 wheels and 33" Tires, and as expected, left the 3.6 feeling a little more sluggish under the heavier wheels/tires. While a supercharger sounds like a blast, I can't see myself throwing that much more $$$ at the Jeep right now, if ever. Thought about trying a throttle controller, but that seems like throwing good money after bad no more than it really does, as opposed to a tune like this that sounds like it would make a more substantial difference.

A few questions if I may, being a total newb to custom tunes.

1. I'm outside of my 3/36 warranty being 3.5 years old (no extended warranties), but I assume I would be pretty much throwing away any remaining powertrain warranty if I go this route and start swapping PCMs, right? How much am I really giving up there that might bite me? I've had all the recalls issued to date completed already, and otherwise, almost never take it to the dealer.

2. The Jeep is my daily driver and don't really want it out of commission for a week or more, so it sounds like I'd need to go the add'l PCM route to avoid having to send in my existing, right? Other than cost, any downside to this approach? For that matter...is the installation pretty foolproof or is there any real danger of bricking the thing through this process?

3. Admittedly, I was unfamiliar with Livernois before I started researching options, but sounds like they have been in the industry for many years. They were frequent visitors around the forum here during development, but checking their profile, it doesn't look like they've visited the board since early January of this year. Not sure if that should be concerning or not. For those who have had their tunes for a while, do you still find them responsive and are they still providing any updates?

Other than those questions just curious if the folks who have had these tunes for a long time, specifically those with the newer manual trans tweak, still happy with Livernois or have any regrets?

 

[Kreepin1]

They used my Jeep to solve the rev hang issue, so I guess I’ve had it longer than anyone

I love the way it drives and have zero regrets. I took it to the dealer once for weird outside temp readings after off reading and they blamed it on the Tazer. (found out later this is as designed to prevent too high readings in stop and go traffic) So expect the dealer to blame any problems on the tune.

The only issue I have is surging just off idle. I haven’t heard on any updates that address this issue so can’t speak to support after the fact.

 

[DWS44]

Thanks Kreepin1...anyone other folks who've gone with Livernois have any thoughts on my post above?

E-85 is not readily available everywhere, I haven’t seen it in my travels for years. I have been told in the more populated areas they are a few stations that carry it. Would possibly require extensive trip planning. Supercharge with a 91 octane tune , available everywhere.

As a few of us with the 3.6 and manual 2022 models have noted, they returned to the GPEC2A, at least on the manual.
