But wouldn't it be like an infinitesimally small tire? When would it shift? What is it about tire size that can change how quickly the diff spins?
Appearantly there is a key point/relationship between the tire circumferance and reluctor ring. What is it? I don't care if the speedo doesn't reflect actual speed of the car. Quit telling me that.
It'* all about rotational speed.
Say the engine is at 4000 rpm, first gear, so wheels are spinning at 1000 rpm (I made that number up).
The VSS sees the 1000 rpm because the reluctor ring should be spinning at the same speed as the wheels or something directly propertional to it(right?), translates it as 40 mph.
How does can that change the measured vehicle speed compared to engine speed?
