Got an IID tool! How to change fuel economy CCF?

Hi all,

Have finally taken the plunge and bought a IID tool to change a couple of bits a bobs on the car.

Fun fact: Official LR dealers and Indys that use the official LR software CANT change the specific CCF settings. Learnt this after trying to enable my DRL's at a local indy for 2+ hours! Ugh!

Anyways, I've seen that I can alter my fuel economy to better match the cars woefully ambitious figures - Could someone please point me in the right direction as to how to do this... and also what sort of figures I should be looking at changing them too? Some people have suggested going from +7.5% down to -7%?

I've got 20" wheels with Cooper Leons 285/50R20 on, PLUS it's been remapped my Alive - Any ideas what sort of figures I should be putting in to make it more accurate...?

Thanks in advance for the help.

Monitor the real fuel economy:
- 2 or 3 full up to filler cap, write how many liters
- record how many km or miles from full to full

now you are able to compare the real economy vs the lie-o-meter economy displayed.....

now you should be able to hypothesize a corrective value.

I imagine that you will have to try 2 or more values before reach the correct calibration.




I also believe that you will return to the initial value stored by Land Rover ...

Psychologically the truth is too hard to accept ......
