how did u do the first calibration to make it read accurate????
The videos don't every load right, I don't know why though.
Also to calibrate the vsm, you need to mount the magnet (I drilled a hole in the h-hub about half the depth of the magnet, and glued the magnet in it.), the you need to mount the sensor no more than 3mm away from the magnet (mine is 1.5 to 2mm away). You then align the magnet with the sensor, and roll the car till the magnet makes one full rotation. Then you look at the ruler that sould be sitting next to the car and see how far it took to do one full rotation.
I know tires wear and you loose speed, that's why I recalibrate it often.
