AEV ProCal Module for larger tires/speedo calibration

I have 35in tires on my jk and the speedometer and automatic shift points have been terribly off. On the highway, when my speedo read 65mph I was really going 72mph, the jk would also downshift all the time or stay in 3rd or 4th gear on level ground. the mpg's were horrendous and i always had to manually control the gears with the auto stick feature in order to improve efficiency. i did some research and found out about the procal module. i just reprogrammed the computer to account for my tire sizes and what a huge difference it makes. the speedo is right and the shifting is smooth and shifts at the right points. the dealer would have fixed this for me, but i understand that everything will go to a factory default if the battery ever goes dead. so i coughed up the $150 and couldnt be happier.

anyone who has larger tires should def look into getting one of these, im sure the fuel savings will pay for itself.

the only downside? now my odometer is accurate too, so ill have to stick to the 30,000 mile warranty instead of the secret 33,000. i did manage to rack up 270 undocumented miles though. hehe

X2!! Made a world of difference. My commute is all city/stop/go driving. I'm getting about 210 miles to a tank now.

stability

i thought i should add that the stability control is a hidden benefit from this also.. driving on the highway and hitting bumps, i felt like i was wobbling on a motorcycle... fighting the 'loose' steering wheel and swaying back and forth. now it is stiff and does not sway when hitting bumps at higher speeds. this improvement alone is well worth the cost of the procal.

^^^ .. aka a "tank slapper"

BTW - The dealer cannot do this flash if you have anything larger than 32" tires.

Just got my Procal and flashed today. With only 33" DT I didnt think it would make much if any difference but it did.Shifts seem to be smoother and more timely if that makes sense. When pulling a gradual hill it was kinda confused at times and with the flash it now seems alot quicker to downshift and hold a gear.I also dropped the TPMS level to 24 and turned on day time running lights which were the main reasons I got the Procal.
