TL;DR - I'm not doing anything yet, but having gotten a few P0120 check engine lights, I think I've worn out my Throttle Position Sensor.
This little bugger is starting to cause trouble.

TL;DR - After installing my second LutzAuto Speedometer Correction Device, I've started having trouble - the speedometer jumps randomly from 0 - 130mph - with it again. As such, I'm removing it and I'll just do math to correct my odometer readings for MPG averages.
This device has such promise.

The incremental calibration is really nice - so much easier than "hoping" with a speedo gear, and having to get a new gear if something between the transmission and ground changes in the future.
TL;DR - I've been happy with the device, though I had to replace it, and I discovered (because of the device) that getting the speedometer to be accurate is NOT what we should all be shooting for!
