I am guilty of a couple of things here and let me point out I am being a bit of a smart ars.
The subject is rather uninteresting. I opened the thread to see why it had as many posts as it did. Once I opened the thread I only read the the last two posts.
Then I posted about a device that would be useful to me. All bad.
Having said that:
Anyone who drives a stick knows what gear he is in. If not one can figure that out from the stick position.
With the two tach method one could monitor clutch slip. It would let my wife know when she was riding the clutch (I never do that) or when she needed to shift based on RMP. It could also give a heads up on when the clutch needed adjusting or replacement.
