reset and all performance data will be cleared. This will not affect your stored calibration
value or the odometer reading.
2. Press the push-button until ‘HI-SP’ is displayed. The gauge will automatically cycle
through the performance data.
3. Start the run, pass, session, etc., as mentioned above.
4. When finished, repeat Step 2 to view the data gathered from the run. While stopped, you
can view this data as often as you wish. However, once it finishes scrolling one time, the
memory is ready to record new data and will begin recording again once the vehicle starts
to move. The highest speed measured over multiple runs will be retained in memory.
Digital Bar Graph Tachometer
Our Digital Tachometer requires a signal from your ignition system, from either the negative
terminal of your coil or a direct tach output lead from the distributor or electronic control module.
In order to isolate the signal wire from electrical noise interference, we recommend all tachometer
wires be routed as far away from any other voltage or signal carrying wires as possible, especially
spark plug wires.
This tachometer is initially calibrated for use with
8 cylinder engines. If you are using it with a 4 or 6
cylinder engine, you must recalibrate the tach for
your specific application by cutting the correct
loop of wire coming from the back of the gauge.
Do NOT cut both wires and leave disconnected
or the tachometer will NOT function.
The default setting for the tachometer is for an 8-cylinder engine.
For 4 cylinder operation, cut the ORANGE wire loop.
For 6 cylinder operation, cut the BLUE wire loop.
Do NOT cut both wires and leave disconnected or the tachometer will not function.
Also, do NOT connect either the orange or the blue wire to the coil!
Note: If doing an LS engine swap you will normally need to have the tachometer set at 4-cylinders.
WIRING INSTRUCTIONS
Tachometer (memory capable) – Green
If your vehicle has a separate ignition coil, connect the green wire to the negative (-) side of the
coil – the wire that goes to the points or electronic ignition module.
If your vehicle has a GM HEI ignition, connect to the terminal marked ‘TACH’, or, on some
systems, a single white wire with a spade terminal.
If your vehicle has an after-market ignition – some systems will connect to the TACH output
terminal.
