Here are some handy suggestions for different ways you can set up and use the features on your D-Force.
If you set the “INPUT” menu item to “SCr” (scramble), then you can use the 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:
?
Steering wheel button - easy access to use as a “push-to-pass” system. You can drive normally on low boost
and access high boot immediately when required (or when you have traction). If you set the scramble seconds
to 0, it will return to low boost as soon as the button is released, or you can have it time out after a few seconds.
?
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.
?
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.
?
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, and the different
coloured illumination on the scramble button gives you a good visual reminder that scamble is active.
?
Warning light or programmable output from ECU - if you have other warning devices such as low water level (for
water injection/intercooler spray), or 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 “INPUT” 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 D-Force, 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.
