Hi, and thanks for your assistance.
Now sorted, issue was low voltage on pin 1, found a crook connection on ignition feed and once fixed was able to obtain connection with correct 5v and interrogate the ecu
Ecu running M48-V60 TC PC running M48-V62 so I loaded 6.0 o to the pc and now all working
I think that means I need to find someone here in Melb with a M48 SUU so that I can upgrade to 6.2 ?????
Cheers Doug
