True, Scotty. But even if sampling rate (I assume you mean time between pulses and not the derivative of the count), I'd wager that they integrate quite a few (yes there is induced lag)... but at 60mph, they're seeing what, ~20 rpm at the wheel so around 1200 pulses per second? If they don't count pulses per unit time (or at least integrate rate for some time), then a missed pulse or two due to noise would create havoc. Assuming this, then a purposeful missed pulse in the train (depending on the integration rate) should be 'lost in the noise'. Integrating or averaging, say, 30 to a 100 measured rates would only induce a 25ms to 75ms delay... likely acceptable IMO.
Agreed that this is indeed playing with safety systems. But with a reasonable approach, much could be learned without putting safety at stake. ANd if the computer is going to balk at the information, I would expect to see the symptoms early.
Obviously, custom sensor disks is the way to go, but the tooth cutting MAY work, and would be an interesting step towards the end.
And Firefly - putting on a larger rear tire (as this thread started) IS essentially changing the gearing.
