Cosworth uses MBE ECUs so I am pleased Morgan went to MBE for mapping .. I hope Morgan used an MBE ECU too!
looks like I am the only ARP4 owner with engine light on issues, which is good as it is hopefully not an ingrained/common issue.
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.
