Wow. I can't believe Chrysler has made it that difficult to modify. I loved the tuner on my 12', my 12' got wrecked and I moved up to a 15' model. While I applaud the solution, it's way over my head financially.

Sad to say I won't be keeping my tuner any longer.

Bumping this thread. How much longer now?

Thanks
Vito

What exactly has been updated for the JK since then? The tunes haven't been tweaked at all? Just extra features like the off-road section, fog-lights?

thanks. got it updating now.

I installed my tuner January 2013, has anything been updated since then?

The MDS function in the tuner actually works? So it runs on 4 cylinders when possible? I never got a clear answer on this. I noticed it as one of the options today when I was thumbing thru the menu.

Is it okay to use the mileage saver tune on 93 premium?

Nice.

Well they put that option in the tuner.

No changes to shift points. No off-road options yet. Yes you can diable traction. Yes you can do custom tunes. and yes I'm sure.

Hm. My MPG is stuck around 14-15. Not sure what is to blame for this? I have stock size suspension. Prior to the tuner I was getting 16. The last 2 tanks I have been driving conservatively and still can't get better fuel economy. I've been using 93 octane since it had zero miles on it, all shell ...

Will there be further refinements?

Bump

Will any improvements be made to the tune for the JK?

I'm going to sound like an idiot asking this, but it appears the cold weather has dropped my MPG down to 14, this is just the cold temperatures right? Not sure if the tuner is also a part of the problem.

8 HP increase huh. I guess all I'm really feeling is the throttle boost and trans shifting better. Can this be improved upon or have you guys tapped out all the power?
