GEMS Landrover / Rangerover P38 V8 ECU

Introduced in version 041F of pscan.

Reads both OBD2 error codes and Landrover proprietary codes.

Reset error codes.

The live data is the same as data as that exposed to an OBD2 tool as this appears to be what a factory tool does.

Learning of EMS code from 10AS (tested) and BECM (untested).
Specifically this puts the GEMS ECU into a mode such that after a power cycle it will learn the next 10AS / BECM code that it sees, it is not immediately learned.

Testing of immobiliser status.
This appears to be of use only on the first power cycle that an EMS is learned following the above EMS learning mode is engaged.
Once an EMS code is learned and then power cycled again the status is not useful.

Resetting of adaptations is not yet implemented.

Output actuation is not yet implemented.

Why was the adaptation reset (LTFT) not implemented, I think it bothers a lot of  P38/Disco owners... Otherwise Pscan is great ! )

okay I'll have a look into it
