Speed Output (
OUTPUT)
If a speed signal is needed for an ECM or cruise control, the SPD OUT terminal can be
used. This terminal can supply a 2000 ppm or 4000 ppm signal. If a BIM-01-1 is used to supply
the speedometer reading, this output is not available.
• When
“output” is displayed, press and hold SW1 until you get “ - ”.
• Release the switch. The current PPM output will be displayed.
• Press and release SW1 to toggle from “ 2k PPM” to “ 4k PPM”.
• When the desired setting is displayed, press and hold SW1 until “ - ” “DONE” is displayed.
• Release the switch to go onto the next menu item.
Exit setup (

“Set done” is displayed, press and hold SW1 until you get “ - DONE ”.
• Release the switch to go onto the next menu.
TACHOMETER SETUP
The control box can be set to read from 1-16 cylinder ignition signals. It can also be set
to read either 12 volt tach signals or 5 volt tach signals found on some engine computers. The
digital tachometer update rate can be adjusted between slow, mid, and fast. The rpm
warning/shift point can be adjusted from 2200 – 14800. The tachometer will read from 350 –
17,500 rpm. At RPM above 9990 the reading will be displayed as rpmx1000 (12,000=12.00).
You can also read the tach signal with the use of a bus interface module (BIM). Dakota
Digital offers the BIM-01-1 that will allow you to read the RPM from an ECU if you are installing
the system in a vehicle equipped with the OBDII diagnostic port or a drivetrain from a newer
vehicle. Most 1996 and newer vehicles have this.
• Press and hold SW1 while turning the key on.
• Release the switch and then press and release SW1 to get to the “TACH” setup menu.
• Press and hold the switch until “- tach” is displayed to enter the tach setup menus, then
release SW1.
• Now you can press and release the switch to scroll through the tach sub-menus, “T CAL”
“UPDATE” “WARN” “SIGNAL” “DONE”.
• When you get to the desired sub-menu, press and hold the switch to select it.
Engine cylinder setup (
T-CAL)
This menu is used to set the cylinder count of the tach signal. It is adjustable from 1 -16
cylinders.
• When
“T-CAL” is displayed, press and hold SW1 until you see “ - ”.
• Release SW1 and the current cylinder setting will be displayed.
• Press and release SW1 to increase the value from “ 01 ” – “ 16 ” or “ bus ”.
• When the desired setting is displayed, press and hold SW1 until “ - ” “DONE” is displayed
• Release the switch to go onto the next menu item.
NOTE: When selecting the cylinder count, be aware of tach signals coming from ECMs,
oftentimes a V-8 engine computer may output a 4 cylinder tach signal. This will be set for
“
04
” not “
08
” as you might expect.
