    Hi,

    Does anyone know the procedure for calibrating a 2017 Cascadia speedometer to work for different size tires? I've read about setting dip switches, but not sure if that only applies to older trucks. Do I need a reflash with a dealer scan tool? Thanks.

    You need proper software (Insite for Cummins/ DDDL 8.03 for Detroit Diesel) Some of us private owned shops have. Dealer has for sure.

    Yes you need to set rev/mile in DDDL. Calculating in your rear end ratio since the VSS is transmission mounted.
