Your heading says VH45dett - to my knowledge the VH 45 did not come out with twin turbos so you are going to be looking at an aftermarket ecu and custom tune. Your best bet is to get a wire in Link (or similar) and get a tuner to install and wire it up. I am not sure if you will find this expertise in Newcastle but maybe a local can help you...otherwise its a long trailer trip down the coast.
Unless of course you are handy with a soldering iron. You can go from the pinout that comes with the ECU and run wires as necessary. However I doubt it will come with a start-up tune for a VH45DETT.
