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.

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.

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 01 01 01 ” – “ 16 16 16 16 ” or “ bus bus bus 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 04 04 04 ” not “ 08 08 08 08 ” as you might expect.
