GPS/GNSS+ Overview The G-100+/200+ can measure distance and speed using either the GPS/GNSS signal or a traditional wheel speed sensor. For most GPS/GNSS Only customers GPS/GNSS alone will provide excellent results with accuracy comparable to a well calibrated wheel sensor. However, like any GPS/GNSS system, accuracy can be degraded when operating in heavily built-up areas or under dense forest cover.
Installation Warning: Installation of the G-100+/200+ may require modifications to be made to your vehicle’s electrical system. If this is not done correctly, expensive damage may be caused to both the product and your vehicle. It is strongly recommended that you seek the services of a qualified automotive electrician to carry out this work.

Step 1: Before You Start Step 2: Fitting to the Vehicle Check that you have the items shown below. You will also need a selection of Securely attach the rally computer to the interior of your vehicle. The most tools, wiring equipment, and a suitable place to work. common locations for this are either on the dashboard directly in front of the co-driver or on the passenger door frame.

Step 3: Electrical Connections The G-100+/200+ connects to your vehicle’s electrical system through the color-coded wiring loom supplied with it. Connect this loom as shown. Connect to a 12 Volt power source that is able to supply power even when the ignition +12V is turned off.

GPS/GNSS Antenna Fuel Sender Signal (G-200+ only) If GPS/GNSS is going to be used to measure speed and distance you will need To use the G-200+’s fuel measurement system, connect the output signal from to fit a suitable antenna. There is a range of these available from Monit. The your vehicle’s fuel sender directly to the green wire on the loom.
Getting Started Step 4: Final Checks Before you apply power to the system check that all your electrical connections are correct. Also make sure that any exposed wires in the circuit are covered with insulation tape or heat-shrink so they will not short against the chassis. Read through this section to learn how to quickly setup and configure the unit after powering it up for the first time.
GPS/GNSS Mode Setup (default) Notes: Once you have finished installing the unit and GPS/GNSS antenna apply power • During initial power up (cold start), or if the unit has been disconnected to the unit to start it up. The first menu to appear will prompt you to select for a long period of time, it may take up to 12 minutes to obtain an initial an operating language (you can change this later on).
Wheel Sensor Mode Setup Distance Calibration If the GPS/GNSS is not being used, you will need to perform a calibration of If you want to use a traditional wheel sensor instead of the GPS/GNSS the wheel speed sensor before it can be used. The device includes a special system to measure distance and speed you will have to disable the GPS/ calibration wizard that guides you through this process using simple on-screen GNSS receiver and perform a calibration of the wheel sensor against a known...
Fuel Calibration (G-200+ only) The calibration wizard works by recording a number of set points as you add fuel to the tank. For best results: The G-200+’s fuel measurement system is designed to work with a wide range of tank sizes and shapes. Before it can be used, the system must be calibrated •...
Basic Operation This section contains information about the features you will most often use while on a rally event. Read through it to familiarize yourself with the product’s main functions and to ensure you get the best out of it while out on an event. Getting Started...
Telemetry Screen Total Distance Counter This is the main screen that appears when the rally computer is powered up Second distance counter. Hold the CLR button down and is the one you will use most often while on events. It allows you to easily for one second to reset.
Entering a Distance Time of Day (G-200+ only) In some situations you may want to set one of the distance counters to a The current time in 24-hour format. Use the SET button particular starting value. To do this: to adjust the value. Select the Set Distance menu.
Advanced Features Measurement Units The device can display distance and fuel information in a number of different measurement units. To change this select Settings > Units. The device does not need to be re-calibrated when these settings are changed. Backlight Intensity When in the Telemetry Screen the intensity of the backlight can be reduced by holding down the MENU button for one second.
Customising the Lower Telemetry Screen Sprint Timer The lower half of the Telemetry Screen can be used to display up to seven The built-in Sprint Timer can be used to accurately measure your vehicle’s different speed, distance, timing and fuel parameters. To reduce clutter the 0-100kph (0-60mph) and 0-400m (1/4 mile) * acceleration times.

These can then be configured in Stopwatch Controls the stopwatch. software to perform one of the tasks shown in the following table.
Stage Recorder (G-200+ only) Speed Alarm (G-200+ only) This useful feature allows you to record your stage time, distance, average The Auxiliary A port can be used to drive a warning light when the vehicle and maximum speed values using an external input switch. It is enabled by exceeds a programmable speed.

Calibration Value Adjustment (GPS/GNSS disabled) GPS Adjustment Percentage (GPS/GNSS enabled) In wheel speed sensor mode the calibration value is stored as the number By default when running from GPS/GNSS the G100+/200+ will calculate and of pulses produced for every kilometre/mile travelled. If you share the device display the true distance travelled.
Troubleshooting Display Resolution The distance counters normally have a resolution of ten metres. If you require a higher level of accuracy this can be increased to one metre. To change this select Settings > Advanced > Resolution. Sleep Timer The device will automatically enters a low power sleep mode after five minutes of inactivity.

Common Problems: The fuel level changes when I turn my engine on and off The output signal from some fuel senders is proportional to the vehicle’s battery voltage. When the engine is running this voltage is boosted by the alternator I’m using a wheel sensor and the distance measurements are not and this can cause changes in the fuel reading.

Error Messages: ‘Error: Invalid Fuel Signal. Refer to user’s manual.’— The fuel sender is not producing a monotonic (doesn’t move in one direction) output signal during calibration. ‘Error: No pulses detected’— No pulses are being detected from the wheel speed sensor during calibration. Check your connections and the instructions To solve the problem: supplied with the sensor.
