R300D - ECU, Maps, Connections and Software

[rotorwings]

What is possible to do with a laptop and the Caterham ECU?

I would like to know:
- what information can obtained/viewed using a laptop connected to the ECU
- What software and cables are required to connect to the ECU
- If there are ECU maps available that might be an update to what is on my car

I've heard that the Caterham ECUs are 'locked', but also very easily unlocked.

Any experts out there with information on how I can begin understanding the ECU?
