I have a maxme, but have not really used it. I am trying to recalibrate the speedo and possibly change shift points on my Ram. I put bigger tires on my truck and had the shop recalibrate the speedo for me. It seems like it was done. But when I have my gps on, it shows that my speed is 2mph different from actual speed. Does anyone know how to do it?
I was also wondering about reprogramming/updating the radio in my CTS4. Can this be done?
Hi,
As far as your radio is concerned no aftermarket scan tool will do anything for radio.
Your tire size calibration should be under the BCM under program tire size.
Changing OEM options is one thing but if you are looking to change something
from what the OEM has or uses requires software from tuning firms and whatever hardware devices they use or recommend.
