3005 Specific Features

• Ability to monitor/display an engine’s AFR in Lambda or AFR by toggling between BOOST and AFR modes. An O2 sensor and suitable wideband O2 controller (such as Innovate LC-2 or AEM UEGO – not included) are required for this function. 

Use Cases

• Standalone boost control
• Boost gauge
• AFR gauge
• Presets for driving styles
• Overtake mode (with button on pedal, and on dash/steering wheel)
• Economy mode (with button on pedal, and on dash/steering wheel)
• ECU integration

3005 Specific Self-troubleshooting Steps

Solenoid Function:

Confirm that the solenoid buzzes briefly when the unit is first powered up. This is an important diagnostic function that confirms the solenoid is operational, wired correctly, and that the head unit has control of the solenoid.

Gauge Function:

Confirm that:

• With the G-Force powered and the engine OFF, ensure the gauge displays zero. If it doesn't, perform a gauge calibration described on page 15 of the instructions
• With the engine idling, the gauge should read negative pressure (vacuum). If it doesn't, check the vacuum connection to the head unit - it may be kinked, restricted, or connected to a vacuum hose that isn't true vacuum

3005 Specific FAQ

My G-Force 3 isn’t reading the correct pressure/vacuum, what do I do?

Disconnect the intake manifold reference hose from the brass fitting joins the hose from your G Force 3 head unit to your intake manifold. With this disconnected, try blowing into the hose to see if your head unit can register pressure. If so, then try to look for any obstructions or damage that may be affecting the intake manifold hose.

If the issue persists, please contact us: https://gfb.com.au/contact-us/ 

My G Force 3 is randomly changing presets? What can I do to stop this.

Navigate through your G Force 3 settings to get to In. 1 (Input 1). Having In. 1 enabled in the case that an external trigger was not used may result in some erratic preset behavior. If you are not using an external trigger, make sure this setting is set to OFF.

Self-troubleshooting Steps

Does the solenoid buzz on power up?

• Check the solenoid wiring for cuts, melted wiring or any other physical issue.
• If possible, carefully connect the solenoid to a 12V power source. When connected/disconnected, the solenoid should tick. Air should be able to pass through ports 2 and 3 when disconnected from power (port 1 blocked), and ports 2 and 1 when connected to power (port 3 blocked)

When the power is ON and the engine is OFF, is the display showing 0.0?

• Calibrate the unit.

Does the unit turn off when the ignition is off?

• The unit should be connected to an ignition switched power source. This means that the unit will turn on and off with the ignition. A power source is commonly found in a fuse box. A fuse tap can be used.

Is the unit connected to a 5A fuse and powering up?

• Check voltage at the connection points using a multimeter. You should see 11-14V.

FAQ

When powered, my boost controller is not at 0. How do I recalibrate this?

Whilst the boost controller is turning on to the “GFB”, hold down the PRESET button. This will recalibrate the boost controller. Process is completed once an “O.H.” is shown on the screen.

Why is my solenoid ticking when I first start up my car?

The solenoid ticks as your first start up your vehicle as a “systems check”. This is nothing to worry about and is just the G Force 3 head unit communicating with the solenoid.

My solenoid isn’t ticking.

The first step is to look at the wiring and connections. Commonly, damage to wiring from contact with the exhaust manifold is enough to cause a short – if this is the case, be sure to relocate the wiring loom to keep away from any potential sources of damage.

Be sure to contact us and send photos/videos (or both) of the steps previously mentioned, we’ll be sure to help source a replacement.

My head unit's display is playing up and not working right, what can I do now?

Although the visual display is impaired, the actual functionality of the head unit is still not impaired. Send us a video showcasing this and we’ll be sure to proceed next with how to organize a replacement for you.
