Ranger Mods

I am trying to get my head around Forscan.
After it has read the modules the PCM & TCM show "module initialization/relearn vehicle data"
Have done a little research and found that tyre sizes incorrect, yet my car is stock 2021 Sport 2.0l Bi-Turbo 20" wheels.
Don't understand. Have been using "OBD2 Australia usb adaptor".Hoping my purchase of Saeb usb dongle will work better.

Not entirely sure what you are asking...

20inch wheels have never been standard on any variant of Ranger or Everest ever, hence why it will be wrong.

The Everest measures 1837mm (72.3 inches) in height, 4892mm (192.6 inches) in length, 1860mm (73.2 inches) in width with a 2850mm (112.2 inches) wheelbase that brings about a total of 2433kg (5363.8 lbs) of unladen weight. The Everest SPORT (4WD 7 SEAT) comes standard with 265/50 R20 front tyres and 265/50 R20 rear tyres. It requires a service every 12 months or 15,000 km, whichever comes first.This is from whichcar.com.
