Calibrating trip meter
Is it possible to change the calibration of the onboard computer in the Disco 4?
The mpg figure and the road speed are ridiculously optimistic.

Why not just take it back to the dealers if it's still under warranty?

Dealers do not have the inclination or the ability and in truth the trip meter is not faulty. JLR deliberately set an arbitrary +% value in the CCF setting at initial manufacture to force the trip meter display to over-read, presumably as a marketing measure.

I knew that you could adjust the mpg calculation (I've done it and its now surprisingly accurate) but didn't know you could also do the speedo with the IID tool.
