The improved CARTEK Shift Light is dashboard mounted device that is designed to indicate to the driver the optimum time to shift up a gear to obtain maximum performance from their engine.
 
The device contains 8 multi-coloured LEDs which form a display sequence that will commence at an engine speed prior to optimum and complete at precisely the optimum speed thereby giving the driver early indication to shift up before the rev limiter is reached or engine damage occurs.
 
There are 2 versions available of the CARTEK Shift Light:
 
The SHIFT-LIGHT (Club) requires an engine speed signal to operate which can be any RPM output from an ECU (5V or 12V square wave), tachometer signal or ignition coil signal. Not suitable for engines with older CDI Ignition systems.
 
The SHIFT-LIGHT (OBD2) can receive RPM through the OBD2 port of any car. This version comes with a dedicated 1.5m OBD2 cable so no additional wiring is necessary. 
 
Features:
 
Configure the lower and upper RPM settings with or without the engine running. Engine only needs to be revved to 50% of max RPM if setting up with engine running, or manually input RPM values using Push Button at rear of Shift Light.
Configure day and night brightness of the LEDs
Choose from 6 Shift Light Patterns – either linear or converging.
Also includes an Alarm feature which can be used to alert the driver of an engine issue, such as over-heating or low oil pressure, by making a connection to a compatible sensor, data logging system or dashboard alarm output signal. * Shift Light Club version only.
Additional RPM filter setting available designed for Historic applications * Shift Light Club version only.
 
OBD 2 CAN bus converter:
 
Many aftermarket car accessories such as Gear Shift Lights, Tachometers or Digital Gear Displays require connection to electrical signals which are often not available on modern cars.
 
The CAN-Bus Signal Converter from CARTEK simply plugs into the OBD (On Board Diagnostic) socket found on most modern cars and provides four useful signals by extracting and converting engine data from the car’s CAN-Bus network.
