[Ovmsdev] CAN bus noise?

I have read somewhere that if you connect a bluetooth adapter with "torque" app you can disable the power steering (or was it the ABS)... so I would speculate that what you are experiencing is not a problem of noise, but rather a problem of the software that was uploaded in the ovms. Only speculation though.

Subject: [Ovmsdev] CAN bus noise?

I am concerned that the OVMS v2 may be adding noise to the CAN bus, or causing problems in some other way (I know very little of CAN hardware, so can't really speculate much).

I have heard other people mention CAN errors when OVMS is connected and yesterday I made my first trip with the unit connected to my C-Zero. During this trip the traction control failed - something it has never done before. The problem went away when the car was turned off and on again, but it seems too much of a coincidence for this to be unrelated.

Does anyone have any opinions on this?
