Generally, the people is only interested in flashing the engine ECU for tuning.
Which other ECUs do you have in mind?

I have this tool and as far as I can see you can flash the other ECUs with software updates. I haven't used this function yet but it looks like it is free to use. There is a charge for tuning maps however.

What I'm not sure of is calibration. For example is it possible to use the tool for throttle body calibration? I don't think it is.

I bought one when I had my D3 (LR3) and the things you can do with it on those is amazing!
Thinking it would do the same on the FL2 I was really disappointed to find it is really limited, especially on the earlier models, so mine will be up for sale to part fund my 10 year service and I'll just use my Icarsoft i930 for code reading etc

i think you are the person i am looking for i have a gap iid tool which is paired with a l322 which i have just sold and i have bought a 2007 freelander 2 which i want to pair with the gap tool but have not got a clue on how to do it could you please help or advise . thank you in advance stuart
sorted now cheers
