In the Classic 900 model it was the engine vacuum. If you were not accelerating (low vacuum) the light would come on if you not in 5th gear. If you stayed in the same gear and accelerated (high vacuum) the light would go out. It does not work as a "downshift" indicator - you have to be smart enough to figure that one out yourself. In my opinion, you need to "become one with your car" and sense when you need to upsift and downshift by the sound and vibrations. meld_b wrote: > It's got to be ground speed too, because it doesn't turn on until a > certain speed.
