The GFB D-Force boost controller is able to display Exhaust Gas Temperature when the optional GFB EGT Plugin is 
used. Installation of the EGT Plugin is simple, the board and temperature probe connect to the existing D-Force loom, 
and the probe is supplied with all the hardware required in the exhaust (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.

D-Force EBC without EGT plugin - part # 3006
D-Force EBC kit  with EGT plugin - part # 3007
EGT plugin kit - part # 3100

The EGT plugin kit (part # 3100) includes:

Plugin board
EGT probe with 2.5m of stainless steel braided wire
Compression gland
Copper washer
Weld-on bung

Menu features involving the EGT display are only accessible when the EGT plugin is connected. These instructions 
include the EGT plugin and menu items, but where appropriate they are labelled as optional.

In  normal  operation,  the  D-Force  display  can  be  toggled  between 
EGT and boost pressure simply by holding the MENU button.

In EGT mode, whenever the probe temperature is below 100°C or 200°F, the display will show 
3 spinning segments to indicate the probe is warming up:

EGT  can  be  displayed  in  °C  or  °F  (see  page  13).  In  either  case, 
temperature is the number displayed x 10, i.e. “48” = 480 degrees. 

EGT DISPLAY

Displays  live  Exhaust  Gas  Temp. 
(*Requires optional EGT probe and 
plugin board to be connected)
