Modding the driver info display?

In theory everything the stock gauges and info displays can show us is available on the CAN bus. It's just a matter of someone figuring out all the custom protocol

In theory everything the stock gauges and info displays can show us is available on the CAN bus. It's just a matter of someone figuring out all the custom protocol extensions and PIDs to get at some of it. Unfortunately the custom extensions seem to be closely guarded secrets. Some aftermarket guys apparently paid off someone or other to get the PIDs and can show data that I'd really like to have generically available (e.g. brake pedal position, oil temps) for datalogging. I'd kill to know what hex numbers I need to tap into a Android OBD-II tool to get those.
