I wonder if you would have to be on the exact same axis as the sensor inside the angle finder with the crankshaft center, so as not to skew the 360/accuracy. If you treat the sensor like a connecting rod, and its off like even a little would it be akin to a stroker crank, favoring one direction?..Not Bashing but curious how the sensor works in 360° if it was not on the EXACT center of rotation..and I'm not talking about the outer box the sensor is in..where it is mounted inside is what I'm getting at. Really neat idea if its perfect against a degree wheel and shows light on ports the same..I do think too much.
