Oversize Tyres Question
I have a IIDTool but this tool cannot be adjust tryes sizes,and my speed and fuel avg. seems to be wrong for this reason. Is it possible to adjust tyres size and others with Nanocom safely ?

Yes the Nanocom allows you to upload a modified CCF that covers not only these options but all editable configuration options on the vehicle. For more information you can have a look at the emulator or even upload your vehicle VIN to the Genesis demo account and see all the options for yourself:

The rolling circumference parameter (shown on the IID screenshot below) is particularly sensitive to maladjustment and must be done with care. The built-in error in the D3 speedo usually gets better with oversized tyres and fine tuning to match the tyres tends to make the fuel calculation worse. In effect you have to compromise on one of the parameters. The D4 is a little easier to tweak.
