A Rover/MG specific diagnostic laptop based tool has recently been launched.
It is the result of a lot of work to enable it to provide much greater functionality than the generic type. It also works on the pre 2004 diesels which were not eobd compliant.
There are some screen shots on our tuning-diesels.co.uk website though we do not as yet stock it.

The ability of those involved to develop this is impressive, particularly in view of the selling price. (£180)
