Speed Output (OUTPUT)

If a speed signal is needed for an ECM or cruise control, the SPD OUT terminal can be

the speedometer reading, this output is not available.

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.

” not “

0808

” as you might expect.
