He is already aware of the language and is working on add ons to his Magnum.
He sent me some sites and I have found a few places that can help.

He did say there is an algorithum for the needles in the cluster that are controlled by a steper motor.

I asked if you can you change the algoritum to read something else and he said "Hell Yea" that is why everyone is using the CAN.

So "if" you can decode the code then you can have the digital gauge show anything you want that the Motec can output and use the spedo as a Boost gauge even.
