I have a maxi sys 908P that i am using on my 2004 Ford 6.0 Excursion. The truck has larger tires so the odometer and speedometer was registering about 5mph under actual speed. I used the programmable features on the MS908P to bump the tire RPM up to 600. Now the speedo is about 3MPH too fast.
The problem: Now whenever i go back to the "'programmable parameters" feature, i can see the "tire size" menu items but when i select it, nothin happens. The tablet stays on the menu. The same thing happens for any menu item in this section.
Any ideas how i get it to load the features when selected? I have rebooted and reinstated the OBDII connector countless times and these are not working.
Thanks for any help.
