Speedometer recalibration device
Surely this has been thought of before, but could a device like a Guino or something be used to make your speedometer read properly with different tire sizes? The signal from the VSS is calculated for the stock tire size(right?), but could that signal be tapped into, put into a calculation for a different rolling diameter using a factor or multiplier, and have the Guino spit out a different number or signal to adjust the speedometer to the new tire size?
Reading the calibration instructions for the MPGuino, it seems this same thing could be done on the VSS to adjust the speedometer. It’s coding and factors or multipliers, yes?
Why isn’t this a more popular thing?
