Tuners or Programmers.....

Finatic Angler

Adventurer
So I am thinking about a tuner for my jeep 14 JKUR. It has a Gobi rack and A 2" lift with a tire just under 34". I do notice that the transmission hangs gears a little longer before an up shift.

Any suggestions on tuners or programmers?

I do have a M101-A2 trailer that I tow and will more than likely add a tear drop to the mix in the next year or so.

Please tell me your thoughts on the tuner you are using and any upsides and down sides to it!

Thanks!

Jim

Jim,
I do not have the same engine as you but I do have some experience with tuners - in my mustang and my WK2 hemi. To be honest with you, you would be better off manually shifting the jeep as you tow instead of getting a tuner to reprogram the ecu and tranny. And maybe adding a transmission cooler/gauge to keep things in check and re-gearing your diffs would benefit you more.

The bad:
The tuners will not provide as much power as claimed (most were measured at sea level/cold weather/etc.)
Cost
Higher octane fuel depending on which tune you do
Voids warranty


The good:
Let's you modify other system settings - fan turn on/off, tire size/speedo correction, multi displacement disable (hemi), transmission shift points, rev limiter, etc.

Agree!! Thats why procal is a good option! ;-)

Didn't realize it voided the warranty :mad::mad:
FWIW, the warranty book that comes with all of the Jeeps is pretty specific about what does and doesn't void the warranties.

Some Modifications Don't Void the Warranties But Aren't Covered

Certain changes that you might make to your vehicle do not, by themselves, void the warranties described in this booklet.

Examples of some of these changes are:
• installing non-Chrysler Group LLC ("Chrysler") parts, components, or equipment (such as a non-Chrysler radio or speed control); and
• using special non-Chrysler materials or additives.

But your warranties don't cover any part that was not on your vehicle when it left the manufacturing plant or is not certified for use on your vehicle. Nor do they cover the costs of any repairs or adjustments that might be caused or needed because of the installation or use of non-Chrysler parts, components, equipment, materials, or additives.

To me, it doesn't sound like using a tuner voids your warranties as much as your warranty isn't obligated to fix any repairs caused by the use of non-Chrysler (like a tuner).

Looks like the only way to flat-out void your warranty is to monkey around with the odometer:

Modifications That WILL Void Your Warranties

These actions will void your warranties:
• disconnecting, tampering with, or altering the odometer will void your warranties, unless your repairing technician follows the legal require- ments for repairing or replacing odometers; or
• attaching any device that disconnects the odometer will also void your warranties.
