Although each of these parameters has a number of settings, it appears as if there are only two main market settings. In Genesis, this is displayed under Jaguar Speedometer Calibration Market which can be found under the Warnings and Messages tab. The choices are:
Market 0: 3.5% + 2kph
Market 1: 2.0% + 0kph
Accordingly, if the above is set to Market 0, then the following parameters are also set:
Jaguar KPH Offset: +2kph
Jaguar Percentage Scaling Factor: 3.5%
I changed all three settings as follows:
Market 1: 2.0% + 0kph
Jaguar KPH Offset: 0kph
Jaguar Percentage Scaling Factor: 2%
This gives a spot on speedo on 19” 255/55/19 and 18” 265/60/18
I've tried all the methods included in this thread, plus another thread I started, plus a few other settings myself and none had worked on my car (MY16 D4). Until, that is, I tried your Market 1 method and it worked a treat. Thanks.
