Hi to all, I would like to open this post to gather all the relative information about accessing the ECU and ECM to read/change parameters of the car.

I've heard that, like in other cars, its possible to connect to the ECU/ECM with a cable and a software, read all the parameters and see which ones are enabled/disabled or which values they have. Like for example, in several Ford cars you can change ECU parameters to increase some hp or connect to the ECM and enable, for example, GPS functionality. I mean, when you buy a car usually all the functions are there but they are disabled if you didnt pay for them, not all, but a few, let's say for example, play movies and not only mp3 files if you didnt pay for the Media feature, or enable more Climate functions and so on.

Does someone have experience with that?

 

See my answer to your other query. Jaguar do not sell cars with options simply disabled in software - you may be disappointed if you are expecting to enable all kinds of bells and whistles that were not factory-fitted.

 

Thanks for your answers.

 

That means that if I don't have the In Control Apps, I can't simply upgrade the software?

 

Correct, InControl Apps requires special hardware to have been factory fitted. I have no idea if any form of retrofit is possible but I very much suspect not.
