Speedometer Calibration?

Post by Court »

Hi Y'all,
Does any body know if you can use versatuner to recalibrate the speedo on a Cx7?
I am currently running lower profile tyres, and it's thrown the speedo out by about 10 - 15km.
Cheers,
Court

This can't be done even with the Mazda MDS. The Mazda speedometer is calibrated out of the box and cannot be recalibrated using the software.
If the speedo is off then look at the GPS speed, figure out the differences and drive accordingly. This is what I do at least.
