I didn't think that it was necessary to make tire and/or gearing size changes with a manual transmission. The automatic needs the information to be stored as parameters or the computer won't shift the transmission correctly. Since the manual transmission is not shifted by a computer, does it need this feature? Maybe for the ESP/ABS to work correctly?
You'll need to use this on the manuals to calibrate the speedometer and the odometer. If you run with the larger tires and don't correct the speedo, your odometer will read wrong. Other than that, you are right. The automatics need this more than a standard.

If you're looking for an actual tuner for the 2011 Wrangler, I recommend the Diablosport Intune. Not only will it calibrate for tire size and gear ratio, it also has performance tunes loaded on it. You can tune the engine to run for better fuel economy, towing, power and more.
It's able to be updated from a computer through a USB port. It's a super easy product to use, just plug it in to the OBDII port under the dash, and follow the instructions on the screen.
If you have any questions feel free to ask. I'll be happy to help!
