When comparing to a GPS, the stock speedometer shows 2-4% higher than the actual speed. When I use an OBD tool (ScanGauge) to read the speed, it is spot on with the GPS, not with the speedometer(strange...).

Most likely a sensor on the transaxle (when I floor it and the wheels spin, then the speedo goes up).

Which gives me an idea: add a second magnet to the transaxle, so the speedo shows twice the speed, then re-scale the speedo's background. Unfortunately, this would double what the odometer logs
