Here are some handy suggestions for different ways you can set up and use the features on your G-Force III.
If you set the “IN.1” menu item to “SCr” (scramble), then you can use the blue external input wire to trigger scramble in a
variety of different ways to achieve different outcomes.
For example, you can connect the external input wire to:
Ÿ Steering wheel button - use as a “push-to-pass” system. You can drive normally on low boost and access high boost
immediately when required (or when you have traction). Once the button is released, the timer will start and the
controller will return to low boost after the designated time.
Ÿ Throttle switch - using a micro-switch on the throttle pedal (like a “kick-down” switch), or a configured output from an
aftermarket ECU, you can make the scramble feature activate when the throttle is floored, for an “automatic” version
of “push-to-pass” - i.e. you get high boost when you need it simply by flooring the throttle.
Ÿ Brake/handbrake switch - you can activate high boost after a certain amount of time has passed during a drag race to
aid traction off the line. In this case, you would set the scramble boost preset to a lower boost setting for launch, and
set the scramble seconds to whatever time you want to engage the high boost setting (i.e. when scramble times out).
So when you are staging, the brake pedal/handbrake is held and scramble is active on a low boost preset. When the
brake is released and the run begins, the scramble timer starts and will turn off after the chosen amount of time,
reverting back to the original (high) boost preset.
Ÿ Toggle switch - use a toggle (on/off) switch instead of a momentary button (press and release) to keep scramble
activated as long as the switch is on. This method gives you easy high/low boost selection, perhaps useful if you
need to fill the car with low octane fuel and the toggle switch gives you a good visual reminder that you’re in low
boost.
Ÿ Warning light or programmable output from ECU - if you have other warning devices such as a knock light, low water
level (for water injection/intercooler spray), high intake air/water/oil/transmission temperature, you could use such a
warning light or programmable ECU output to activate scramble to a lower boost pressure to help protect the engine.
If you set the “IN.1” menu item to “bOOSt” (boost preset selection), every time you activate the external input, the
controller jumps to the next boost preset.
This can be used to set up a kind of “boost-by-gear” feature for drag racing situations. You would connect the external
input to a clutch switch or gear selector switch in such a way that it triggers with each gearshift. Then, when you stage
your car, manually select boost preset 1 using the buttons on the G-Force III, and then each time you shift gears after
your launch, the external input on the clutch or gear selector will activate the next boost preset. Since there are 6 boost
presets, you can tailor the peak boost, rise rate and taper for each gear.
Tips
17 - Additional info
The buttons appear to be locked:
If the boost gauge is currently reading higher than zero, the menu is locked out and the scramble/preset buttons do still
work, but the display will not change to register a button press. If the engine is off and the gauge is still showing higher
than zero, re-calibrate the gauge - see page 15.
The solenoid buzzes constantly with the ignition on when the engine isn’t running:
As above, it’s likely that the gauge is showing higher than zero, and hence the controller is attempting to regulate boost.
Re-zero the gauge as per page 15. Also, hit SETTINGS once to check that the duty cycle menu shows a recorded peak
boost. If peak boost is 0, your gain function isn’t working and the solenoid starts pulsing from just above zero.
With the engine off, the gauge does not show zero:
Perform a boost gauge calibration, as described on page 15.
