D force The GFB D-Force boost controller is designed to accurately control boost pressure on all turbo diesel engines that use a traditional wastegate. It incorporates an advanced and unique boost control strategy that allows the user fine control over the peak boost, rise rate, and closed-loop correction. - Page 3 (you will need to weld the supplied bung to the exhaust pipe). The D-Force kit is available with or without the EGT plugin, and the EGT plugin kit itself is available separately and can be added to an existing D-Force at a later date if desired.

Please note that the D-Force is NOT recommended for use on turbos of the variable nozzle type, i.e. VNT. The D-Force solenoid should be mounted in a position away from significant heat sources (such as the exhaust manifold and turbine), and where it is protected from rain or splashed water. -

100 is the fastest. For more details, see page 10. Sensitivity Controls how strongly the D-Force resists changes in boost pressure. Adjustable from 0-100, where 0 results in Display scrolls “SEnS”. no correction and, and 100 is the strongest. -
Page 8: Boost Presets
The D-Force has 6 boost presets (P1-P6), each of which can be individually programmed and accessed quickly on-the- fly using a variety of methods. There is an additional preset called “SCr”, which is the preset that is activated when the scramble feature is used. See page 12 for more info on scramble. -
Page 9: Setting The Boost Pressure
When done, tap “MENU” to move on to GAIN, or hold “MENU” to exit. In either case, the duty cycle setting and peak boost will be saved to the boost preset that you are currently in. The D-Force will use the stored peak boost as the target, and will use this target boost for the GAIN and SENSITIVITY features. -
Page 10: Gain
Gain The Gain setting controls how fast boost pressure rises during spool-up. NOTE: the gain setting requires a target “peak” boost to be set up in duty cycle. If you adjust duty cycle without performing a boost run, the target boost will be 0 and gain will not function. Gain is adjustable from 0-100, where 0 gives a factory-like spool up, which is basically the “natural”... -

Running Mode. There are limits to what the D-Force can do with the existing turbo and wastegate – if the duty cycle setting is already quite high, there is not much adjustment left for the controller to make if boost drops off –... -
Page 12: Scramble Boost
The D-Force uses a unique scramble approach where it jumps to a dedicated boost preset (SCr) when activated, instead of simply adding extra boost to an existing preset. This method offers much more flexibility in how it can be used because you can tailor the duty cycle, gain, and closed-loop correction specifically to suit the purpose that you intend to use the scramble feature for. - Page 13 egt - temperature units The EGT (Exhaust Gas Temperature) Units setting is only accessible if the optional EGT plugin board and probe are connected. Without the EGT plugin connected, the menu will skip this setting. Within this sub-menu, pressing the up button sets the units to °C (default), and pressing the down button sets it to °F. NOTE: Regardless of the units you select, the display will show the temperature as a number x10.

NOTE: The Overboost feature CANNOT protect against a boost overshoot caused by a stuck wastegate or popped wastegate/solenoid hose connection, since these kinds of failures are outside of the D-Force’s control. From Running Mode, use the “MENU” button to navigate to the Overboost setting (display scrolls “OVEr bSt”) Use the “UP/DOWN”... -
Page 15: Display Setting - Units Of Pressure
- units of pressure Display allows you to configure the D-Force to display boost pressure in PSI (default), BAR or kPa. From Running Mode, use the “MENU” button to navigate to the Display setting (display scrolls “dISP”) Use the “UP/DOWN” buttons to select from “PSI” (default), “BAR” or “KPA”... -
Page 16: Idle Calibration
Idle Calibration is a feature that allows you to adjust the switching point that the D-Force uses to determine when the engine is not under load. This switching point essentially tells the D-Force that the engine is no longer under load so the solenoid can be turned off and the Peak Hold value (if activated) can be displayed. -
Page 17: Colour Settings
Colour settings Colour allows you to configure the button colours - both the normal “background” colour (i.e. when not pressed), and also the “feature active” colour, which is the colour a button turns when either scramble or preset features are activated (see pages 6 and 10). -
Page 18: Additional Info
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. -
Page 19: Troubleshooting
It may hold boost stable for some of the rev range, but at high RPM it is wide open and not flowing enough to prevent boost from rising further. At this point the D-Force can do no more, the only solution is a larger wastegate. - Page 20 Once the D-Force knows the duty cycle that results in the target boost pressure, it can then make changes to the duty cycle to compensate for small variations in boost (when a value for “Taper” has been entered).
