So this will be a few part review as I get used to the newly tuned Jeep. I purchased the Mycalibrator [info/discussion thread here] with a new unlocked PCM so I can go back to stock at any time for service work.

Part 1: Setup and install
  • It takes a bit of back and forth between ordering, receiving the parts, and sending the tune file back and forth. Mostly because they had to load my factory tune into the new PCM and add my strategy. I believe it took me about 2 weeks from start to finish. All in all Livernois was absolutely excellent to deal with. Very responsive and answered ever question I had. Blows the competing companies out of the water.
  • The install is pretty much cake, although I had old instructions for the bypass cable and could not figure out where it plugged into the CanBus junction. FYI, it is behind the glove-box on the lower left. Act like you are replacing the cabin filter and its right there. Super easy. I swapped PCM's in about 15 minutes. Again, cake walk as it's only 3 bolts and two poorly made lever locks. I do wish that Livernois warned me that the jeep will run like crap on first start up as the new PCM is in fault mode. Tensed my backside a bit. One restart and I was good to go.

Part 2: Programming
  • Again, easy as can be. Follow the instructions and load your performance tune and the transmission tune(if you want). Takes a minute or two for each to load. Just don't unplug the CanBus cable while the vehicle is in run or accessory when you are done. If you do it will throw a code or two and you will need to clear them to continue. Livernois service was fantastic here too. Answered absolutely everything for my plethora of calls and emails.

Part 3: Performance (after 1 day of driving)
  • The 93 tune is great. The engine runs so smooth and there are no real missing points in the power band. And even better it somehow shut up the god awful loud radiator fan. Its still on, just quieter. That might have been worth the price for the new PCM alone. The idle is smoother and quieter and the gas pedal takes little effort to get you anywhere without feeling aggressive. 93 and the stock transmission setting you get the extra power and it just cruises so nicely.
  • The transmission tune is also very good so far. It is a bit more aggressive and compliments the extra power without a doubt. When I had the Superchips Pulsar I found the throttle/transmission modification to be way to aggressive in comparison. If you have a mall crawler you may prefer stock but that is so subjective as I am nit picking here. Lets see how it learns my driving style over the next week or two. After ~200 miles the transmission tune is great. Not sure I will flip it back to stock ever.

Minor probably unrelated issue.
  • My AC fan now has a max speed of wherever it was set on start up. It will go lower but not higher unless I turn the fan speed up and restart the Jeep. Everything else is normal. I rather doubt the tune or PCM caused this as they should be separate systems, but it never ever did this until I put the PCM/tune in and it has done it on every drive since. Maybe its because I added the 7" screen previously? We shall see.
  • Edit: It looks like Livernois already figured it out(in less than 24 hours). Fully disabling ESS caused some type of error. New tune is in with ESS on and I am all good. Their service is really excellent.

All in all it is a top notch product and I am happy after a day of use. I will see how it learns over the next week and add more info as we go.

I have run both the 87 tune and the 93 tune with the transmission tune on and off. No matter what tune is used the engine is sooooo much smoother now. No dead spots in the power band like stock and I can cruise without that dead spot around 1500 rpm. My mileage is shooting up(when I dont get on it for fun) and even the 87 tune is worth the price of admission. Such an improvement all around. So far I can't recommend this enough!

General probably would get more attention although I think it will be of more use here in the long run. Based on the lack of info for other tuners I want to make sure people can find this here.

Curious to see if anyone will run E85 to get that max claimed 50HP. I’m very interested in this tune, it’s a heck of a lot cheaper than the hamburger install I’m interested in too.

When you tried the 87 and 93 tune, did you run fresh tanks of fuel with those ratings or was it the same fuel?

Also, could you describe how to check for the dead spot you mentioned at around 1500 rpm? Is this when crawling? I rarely stay at that RPM under normal use to notice.
