Re: Changing default Speedo to MPH from KMH
Posted: Sun Apr 07, 2019 6:08 pm
This is just thinking outl oud, and may not apply to newer vehicles/f150 but I've been comparing Canadian and US crown vics and grand marquis (2007-2011). This task inteself is easy as there is only a single line of code for the panther platform IC and only one block of data that is used. Comparing similar vehicles and the as-built data, I have not found any difference in the code between the mph and kph clusters which leads me to believe that the default reading is hard coded (in part due to the fact that the primary speed indicator is an analog display. The odometer is switchable between kph and miles, and the digital/analog display on cars so equipped is also toggleable between miles and kph). I hope I'll be proved wrong on this, but just want to present it as a possibility if ford retained that programming method.
