tire size problem and tranny shift point not working 05 jgc

[JohnHale]

Hello,

I cannot change the tire size in any of the tunes that are on the preditor.. i also cannot change anything with the transmission shift points or anything related to that.. the reason i bought this tuner was the fact that i could change the tire size and i cannot do that.. i have 24 inch rims on my truck and well you can see why i was looking to change the ire size.

Please help.

I didn't find the right solution from the Internet.
