DSP Tuner kinow adjust vs V2

[TFZ_Z06]

I forget, but do I need the voltage switch (5 position) wired to pcm to swap dsp tunes? Or can I do it via V2? I want to remove the switch so when I smog in a year, the mod won't be visible.

LB7 & LLY can switch via the V2, LBZ & LMM cannot, they require the hard wired switch.
