ECU Master Gear Indicator The digital gear indicator is designed to work with an original or aftermarket ECU to display the current gear with an optional shift light. Gear calculations are made based on vehicle speed and engine RPM via OBD2 or CAN, or by using a transmission position sensor. The unit is fully configurable via CAN BUS (communication, shift points per gear, etc.) and can be used with virtually any CANBUS-based ECU. Thanks to the large and bright display, the indicated gear is readable in all lighting conditions. The display brightness can be controlled via CAN or with a potentiometer (when the transmission position sensor is not connected). Features: Reads gear via CAN, OBDII, or analog gear sensor. 3 RGB LED customizable shift light. Easy-to-read large display (size). Configurable via CAN BUS. Free software updates.
