Anyone using the AEV Pro Cal on their 12' ? Is it worth it? I am running 285/70/17 MTR's on a lifted 4 door JK With 3.21 gear ratio.
What will I benefit? Are shift points that much better?

The AEV unit is not a tuner. It will only change settings like gear ratio, tire size, tpms disable or set to lower value, etc...

I realize that just wondering can I live without? Or bite the bullet. I am going to check speed with Gps and compare for starters

 

I installed 295's and speedo was off around 5mph so it adjusted the speedo shIft points and mileage it was well worth it for me

 

I run it. All i use it for is speedo correction and to run my fogs as daytime runnung lights. You can do other things like high idle or change gear ratio. My speedo was only off by 3 mph

 

I bought the procal with my new tires. If you don't recalibrate it may mess with the stability control.
It has some neat features: one touch lane change, daytime running lights, helps center the steering wheel, TMPS adjustment and spedo calibration.

 

I think so. My AEV ProCal showed up today - this thing is much smaller than I was thinking it was - almost tiny.
Now I just need some new tires to try it out....
Other notes - as expected the programer "locks" to your VIN - so no sharing with your buddies (you can reset it and lose your custom Jeep settings and then you can re-use the module)

 

Yes, buy it.

 

Is it easy enough to figure out??? I am the most computer illiterate person I know..
