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’s 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 future bus interface module (BIM). Dakota Digital offers a BIM that will allow you to read the speed signal from an ECU if you are installing the system in a vehicle equipped with the OBDII port or a drive train from a newer vehicle, most 1996 and newer vehicles have this.
