Programming Jumpers
Digital Tach Filter On/Off
In most cases, this jumper can be left in the OFF position. Some new vehicles use less than 12 volts
in their ignition systems. The unit may have trouble learning the tach signal in these vehicles.
Changing the jumper to the ON setting changes the trigger threshold of the digital tach circuit so
it will work properly with these vehicles. The vehicles affected include many newer Dodge/
Chrysler/Plymouth vehicles, such as the Neon, Cirrus, Stratus, Breeze and LH-based vehicles.
