Installation Manual

MAN 650314:J

If “Bus” is selected for the sender type, the speed signal should be coming into the AUX

I/O port through the use of a BIM-01-X module. The adjustment ratio ranges from 75 – 125% on

this setting as it is assumed that the signal from the external device is the correct pulse rate, there

are only provisions for slight adjustment. The LCD1 message will light up and show “adjust

spD xxx%”, XXX is adjustable from 75 – 125 and is the percentage the input is corrected by. If

set to 100 the signal is uncorrected and whatever the BIM module is reading is displayed on the

dash.

NOTES: For adjust mode you can follow another vehicle, time yourself, or use a GPS as a

reference. A chassis dyno is another excellent way to use the Adjust mode.

Also be aware that the odometer miles are calculated from the speedometer cal value; if it

is not calibrated properly, odometer miles could be higher/lower than actual.

Service countdown meter (Service)

The service countdown meter allows you to set a mileage value that will decrease as the

odometer miles increase. When the value gets to zero, a message “Service DUE” will appear

on the LCD1 message display on power up to remind you that service is due. This can be used

for routine maintenance reminders such as oil changes.

When “service” is displayed press and hold SW1 until the message screen changes.

Release the switch and the current service setting will be displayed.

Press and release SW1 to increase the value from “OFF” then “500”-“7500” in 500 mile

increments.

Once the desired setting is displayed, press and hold SW1 until “DONE” is displayed to

save the value.

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 2,000 ppm or 4,000 ppm signal.

When “output” is displayed press and hold SW1 until the message screen changes.

Release the switch. The current PPM output will be displayed.

Press and release SW1 to toggle from “2k PPM” or “ 4k PPM”.

When the desired setting is displayed, press and hold SW1 until “DONE” is displayed

Release the switch to go on to the next menu item.

Exit setup (done)

This will allow you to exit the speed setup and go on to the next setup menu.

When “speed done” is displayed, press and hold SW1 until you get “DONE”

Release the switch to go on to 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 2,200 – 14,800. The digital tachometer will read from

300 – 17,500 rpm, at RPM’s above 9,990 the reading will be displayed as RPMx10 in the

message center (12,000 RPM displays as 1,200).

You can also read the tach signal with the use of a bus interface module (BIM). Dakota

Digital offers a BIM-01-X that will allow you to read the tachometer signal from an ECU if you are

installing the system in a vehicle equipped with the OBDII port or a drivetrain from a newer

vehicle, most 1996 and newer vehicles have this.
