Bought a new truck(16 Tradesman) that was build for canada. Everything switched over to standard good to go. But the digital speedo didnt match the analog one, the digital one was correct the analog one was 3 mph off(slower).
I had factory 17in wheels with rubber on them per the window sticker. Found OEM 20s off a 15 ram locally and swapped them out.
Now the digital speedo is 3 mph off(slower). Now that I am looking at this I dont know what analog is doing, need to check.
Did some reading this seems to be common on canadian trucks. My question is can a dealer flash the PCM to account for 20in wheels?
