The timing curve programmed in the box would change it, and they are specifically talking about timing being retarded for nitrous use in the video. You both are assuming the mechanical advance is doing it, but there is no evidence to prove or disprove that.
Can you see the rotor position has changed... you tell me how electricity will change the physical position of the rotor.. that isnt a optical illusion EDIT that video is talking about phasing the rotor and talks about what COULD happen if the rotor doesnt line up... and he talks of retarding the timing in the case f running spray... the title of the vid was rotor phasing
