TACHOMETER DIP SWITCH SETTINGS


The control box will work with 4, 6, 8, and 10 cylinder ignition systems. The DIP

programming switches are located inside the control box, so the cover must be carefully
removed to get access to the switches. Make sure the key is turned off before opening up the
control box so that there is no power to the system. The switches numbers 5 and 6 select the
number of engine cylinders. The settings are as follows:

Engine cylinders

Switch #5 Switch #6

Bar tach

Switch #4

4

ON

ON

6000 rpm

OFF

6

OFF

ON

8000 rpm

ON

8

ON

OFF

10

OFF

OFF

The default setting when systems are shipped from the factory is 8 cylinder.





In addition, the tachometer bar graph can be set to read 6000 rpm at full scale(switch #4

OFF) or 8000 rpm at full scale(switch #4 ON). This option would have been specified when the
order was originally placed and the switch should be set to match the display system lens
engraving. Systems with both a digital and bar graph tachometer are always set for 8000 full
scale(switch #4 ON).

Because some systems have a digital speedometer with a bar graph tachometer directly

above it(55 Chevy car) and some systems a have separate digital speedometer and digital
tachometer, each having their own bar graph readout(73 Chevy pickup), switch #8 selects which
style display system is being used. For 5-gauge systems with a bar graph tachometer directly
above the speedometer, turn switch #8 OFF. For 6-gauge systems with a bar graph
speedometer directly above the digital speedometer, turn switch #8 ON. This is set correctly at
the factory before shipping to match the display system that it is paired with.

METRIC SELECTION DIP SWITCH SETTINGS


Switch #7 selects whether the temperature will be displayed in

°

F or

°

C and also sets the

speedometer for MPH or KPH. For MPH/

°

F turn switch #7 OFF. For KPH/

°

C turn switch #7

ON. Changing switch #7 does not change the speedometer calibration. Speedometer
calibration is discussed in another section. This switch will be set from the factory to match the
display system lens engraving. If this is changed, a new lens should be purchased so that the
labeling matches the gauge readings.

Tachometer display type

Switch #8

Bar tach only (no digital numbers)
