It's actually pretty dramatic on how much better it performs compared to stock. Throttle response, cooling fan settings, power enrichment, rev and speed limits, plus transmission shift characteristics on the 8-speed trucks dramatically improves how it feels.seems like it would be a noticeable difference that is worth it if similar results for most people that do it.
Well, truthfully, these trucks SHOULD be running premium fuel right from the get go. They work with 87, and we can actually still make improvements, but it's still held back due to the high compression these engines have.Good stuff. When power adders like superchargers and turbos claim gains, you have to factor in that some of it comes from the higher octane tunes they run.
Has anyone done a custom dyno tune on their stock 3.6 for higher octane fuel? I imagine it has to be better than these canned tunes.
Well, depending on the feature, our tuner may already do what you need since we do support tire/gear, and many other service functions on these.I’m super interested in this. I just gotta figure out my compatibility with my JL Tazer Mini. Seems tuners can’t be plugged in simultaneously with the Tazer. I don’t get my Jeep until next week, so I’ll just have to see what I need on the Tazer and if I can unplug it.
Well, E85 actually helps cool the engine off, and so does higher octane tuning as the engine temps reduce when better fuel is used. But on E85 it's about 15% cooler than gasoline, and we actually have the fans kick on sooner as the OEM settings sometimes don't turn them on until nearly 230*This would be question for the tuner. Is the factory cooling system adequate enough on the trail to have 50HP and TQ gains? I would like to see the difference in the temp charts from constant running at higher output v normal. Doesn’t this need to be tested out in real world conditions like crawling on the trail in desert heat etc to make sure that you don’t blow a gasket?
Yes, and No. In production form, absolutely not. But, FCA actually gave the engine everything it needs to be able to be flex fuel, just they didn't actually do it. So, with our proprietary calibration and code changes we are able to activate and deliver this functionality. Honestly, once you drive one on E85, you likely will never want to put gasoline back in it, although you can of course.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.
Well, hopefully you wonder no more!First thing I wondered!
I can’t speak for everyone but I’m sure most appreciate the team getting on here and answering questions themselves. It’s great to see active involvement!Firstly, I hope it's ok that we signed up to post in here to answer some questions on the tuning for the JL/JLU/JT that we offer.
Sounds good. But do you mean 30000 permutations or 30000 parameters?Well, truthfully, these trucks SHOULD be running premium fuel right from the get go. They work with 87, and we can actually still make improvements, but it's still held back due to the high compression these engines have.
As for results vs. a "custom" tune, well truthfully we build all of these custom for your vehicle, and it's modifications. The tuner actually comes blank for this reason, because they are always custom. And, I am a firm believe in a well developed mail order tune being far superior to going to a local place for a "custom" tune. These are very complex calibrations, with over 30,000 parameters, and we bother to reverse engineer 100% of them. This is what sets us apart from most places, as we develop the hardware, software, and calibrations here, with our own purchased development vehicles, so our cars are the test units, not yours. Most "custom" tunes the person is actively learning what to do and not do on your vehicle.
