Have you been able to interact with/set the cruise or speed limiter?

I believe, but I'm not sure, that the airbag system can be triggered by an errant CAN message (unconfirmed) - if you're injecting signals onto a live car, how are you ensuring this doesn't happen and do you know what they are? Would be a right pain to write off your car with a mis-sent message.
I can display the current cruise set speed as it is broadcast on the CAN bus.
As for the speed limiter, that is coded into the ECU and would need to be found/reprogrammed to change it.

Most of the time, I am just receiving the CAN bus message and displaying it... no chance of anything bad happening.

The messages I do send on the CAN bus are the same ones that are already on the CAN bus, so I'm not adding anything new... no chance of anything bad happening.

As for airbag deployment, the airbag module uses multiple inputs from the CAN bus (like forward/reverse, gear, speed, etc) and the crash sensors to determine air bag deployment.

Overall, I don't think there is any chance of air bag deployment via CAN bus.
