If it's an MBE ECU then you can download a copy of the EasyMap software and use it to have a look at all sorts of stuff that your ECU is doing. You won't be able to change anything as the ECU itself will be locked, but it's fascinating nevertheless - much more informative than simple fault codes.
You may need a CANBus adapter to go between the OBD port and the USB lead to your laptop, but you can get one from SBD Motorsport.
that is way beyond my pay grade .. I don't even know where the ECU or the OBD port (whatever this is) is.
