looks like this will be totally doable with the 'FORSCAN tool once it gets the required updates for the bronco. still don't know if it requires the full laptop version or if the ios/android smartphone 'lite' version is sufficient

I just recently bought the MX plus wifi adapter that I use my tabet like a scan tool.

I also bought the OBDLink EX FORscan adapter for my laptop.

I'm still in the learning curve with my new toys but I believe you have to use the laptop for tire calibrations.
