I use OBD Fusion as a driving monitor (showing LOD, HP, GPS Speed, Vehicle Speed, RPM, and MAP) and have looked longingly down the list of custom PIDs available for Ford and GM. Do you know of a MB pid list anywhere?
It would be nice to get it talking to other modules over CAN... things like the TCM to pull up atf temp.
I haven’t gone very deep into it at all - the idea of bricking a module weighs heavily - but being able to passively watch the content flowing on the CANBus is certainly an interesting possibility. Is there a known safe elm script that opens comms to other modules?
