About 2 years ago I changed my rear end gear set from 2.47 to 2.82. I have been reluctant to re-calibrate my speedometer as I wasn't sure if I would keep the 2.82 gear set and the fact that the local speedometer shop wanted $250 to re calibrate speedo.

So I have seen many re calibrators but all were fairly expensive and some were rather large. But I recently came across this very simple and very tiny one for $90.00 delivered.

I hooked it up and it work's great.

I will add that my speedo is using a 3 wire hall effect sensor instead of the original 2 wire passive VRS sensor. So I would ask them about that before purchasing. But so far I am very happy with it.

They are a motorcycle oriented company and sell the unit as plug and play for most bikes but the universal kit is what you use for cars and trucks.
