Allows simple installation of an aftermarket speedometer and/or tachometer. Plugs directly into motorcycle’s diagnostic port. Connects to bike’s data bus and outputs traditional analog signals. Features outputs for speedometer signal (8000 ppm), tachometer signal (adjustable for 1-, 2- or 4-cylinder), check engine signal, accessory power and ground. Digital readout works like a scan tool; allows reading back and clearing diagnostic codes.
