what does the power button do? the one next to the lighter, increase timing?

 

it increase the speed, i think it changs the gear faster for the transmission.. not sure.

 

it does not affect the timing at all, it simply adjusts the shift points for the auto transmission

comfort will shift at lower rpms, power will shift at higher rpms, if you keep it in the middle, it will automatically select which ever mode it thinks it should use

also,

there is lots more info about this in the archives
