No problem! The proper gear ratio will totally transform the way your Jeep drives.
The procal is what you do when you go up in tire size. You can change gears, but would be a bit overkill. What size tires?Is using the tuner to adjust shift points an acceptable alternative?
The AEV procal takes care of that for you. Just input the size tire into the chart and then set it up in the procal. Will change your shift points. Easy fix
Is using the tuner to adjust shift points an acceptable alternative?
It changes the shift points, changes gear ratios if you change gears, will change your light settings for headlights/fog lights, sets your PSI threshold for your tire settings. Just to name a few things. Does what it is intended for...changing the shifting points when you go up in tires, and all you do is plug it in. Seems like a no brainer to me. But if somebody wants to download an app to reset shift points they can too I suppose.Waste of money. The Procal does not even half the stuff the J-Scan app does. The J-Scan app does everything the Procal does and so much more, and costs $16 plus about $20 for the Bluetooth adapter. Not to mention it's an app, so you already have a phone.
Procal is obsolete anymore if you ask me.
To my knowledge you can not change shift points with any of the tuners, including HPTuners (which is the most comprehensive full access tuning solution I know of).

So I guess the next question I have is I’m going with a 35x12.50r17. Stock on mine was a 255/75r-17. Which should be a 32” inch tire if my math is right. I know I have the 3.73 rear gears. That’s a 9% increase in tire diameter. Is it necessary to re-gear with such a small increase? Or would the jscan app and adjusting the speedometer be sufficient. If I had 3.21’s I would jump up to a 3.73 or even a 4.10 since I was already changing them.No problem! The proper gear ratio will totally transform the way your Jeep drives.
I would definitely regear. I imagine that will feel very sluggish running 35s. Just my opinion though.So I guess the next question I have is I’m going with a 35x12.50r17.
