I always thought it would be required that a CAN BUS enabled tune would turn itself off it anything was ever connected to the OBDII port but now I understand why they have not enabled it that way. It's a sneaky way to block would-be car thieves. I would be willing to bet if users were to demand that the piggyback disable itself if anyone were to plug in to the OBDII port such a firmware revision or option would be quickly released. Has anyone ever asked for this? |
Awron's Digital display is a good example of a passive mode, this is shown at 2:21 of the video below:
As soon as a diagnostic connector is plugged in, it goes into diagnostic mode. The Macht Schnell EVC module also is passive, leaving the OBD2 port open while in use.

Testing as we speak. Once these become mainstream, piggybacks will start phasing out.
