CAN bus powertrain information

Are there messages on the drive bus that transmit information about fuel injection quantity, ignition timing, and air mass (mg/stroke or measured g/s) in a Golf V?

I wouldn't know the ignition timing or air mass values as it's related to a CAN bus system.

The only way to obtain that data would be through TP 2.0 and KWP2000 protocols.nThe only way to retrieve the data would be through TP 2.0 and KW-P2000.The only way to request the data would be through TP 2.0 and KW-P2000.

ELM327, Arduino, and the corresponding OBD query?
There's almost certainly an ignition timing setting there.
