Grabbed it off ebay for $154 shipped, a steal imo.

Installed the regular octane tune, disable the tire pressure light, set my tires to 32.50 and didnt enter my gears.

Now for my questions, I've got 33x10.50x15 KM2's, do I enter 33" for the tire size or do i measure my tires myself and enter that reading? Also, I do not know what gears my auto sport has, anyone know?

After a quick drive, throttle response has gotten much better, low end power has increased too.

 

Can't disable the light unless the programmer stays plugged in. Can lower to 2 PSI, though.

I have 35" KM2's and need to run around 33.5" to match the GPS. All tires run a bit smaller when the weight of the Jeep is on them, and all seem a bit different. I'd measure with a GPS or roll them out. Find a stretch of highway that's reasonably straight and count off mile markers vs the odometer to verify.

To find what gears you have, jack one rear tire off the ground and count how many times your driveshaft spins for each tire revolution. You should be able to get pretty close.

 

hmm, went for a 5 minute drive and the light didn't come on.

thanks for the tips.

 

x2 the GPS mph response. I'm running 285s (32.8") but wound up setting the tire size at 31.50 to get the speedo accurate. I just dl'd the Hypertech Max upgrade. Including that throttle response option was HUGE.

 

what did you put for throttle response? do you have an auto?

 

Do you have the sensors installed in the wheels? Are they in the cab of the Jeep? If they are completely missing and are separated from the vehicle your light should eventually come on. It might take a while.

The reason I said "separated from the vehicle" is I read were someone took the sensors and built a pressure tube to keep them in. There is apparently enough bouncing around in the Jeep to activate them. At least that what he wrote. I know my spare would trigger the TPMS if the pressure was low, even though the owner's manual suggests it shouldn't do that.

Let us know how you like the other features!

 

PM me your VIN and I can tell you what gears you have. As long as they are still stock.

 

One week later of daily driving, still no tpms light.
