Thanks for that Jpristel, I know there are loads of scan tools around but nobody would tell me which one I needed for the Crossfire, just that 'it might work, we haven't tested it', and was reluctant to spend money until I knew it would work, and all the pro tools are stupid money. I was interested to find out what the protocol was for tuning purposes rather than just reading the fault codes. Also most of all the DIY/low cost OBD readers are based on the Elm chipset that I had already got to hand and had tried. Many of the vendors merely box these up and charge double for them! Looking at the spec the Vital nit seems to be ELM based but with a Bluetooth module added.
Anyway I now know that the Crossfire is ISO so I can start playing...
edit:
When I finally got it to work I didn't have to have the engine running, just the ignition on, at least for the PIDs I was reading at the time.
Cheers,
Simon.
