A friend of mine had a thought with regards to the DSP switching. Since the V2 is the only way it will be possible to switch the LBZ/LMM tune (if/when it comes to be), but a switch could potentially be considered "safer" (Eaiser to use), would it be possible to configure an A/D input on the V2 or Autocal to accept one of the DSP5 switches and change the tune that way versus fumbling around in the V2 menus? That way, you could hook the V2 (or Autocal) up to the OBD2 port, connect the switch up to the unit, hide it somewhere and switch tunes with the twist of a knob like with the LB7/LLY.
