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.
