Tested on early P38 and Discovery 1.
This red and yellow ECU was fitted to P38, Discover 1 and Rover 800 only up to 1996 (and slightly longer in North America).
It is supported by pscan but requires an additional cable adapter. If you want to use pscan with this ECU please clearly state that you need the MPS adapter when placing an order.
Note that the later TRW SPS ECUs are not yet supported.
