he WHI E/DIMMER circuit must be installed and supply 3 to 12vdc before the PPR can be
progammed
Attach the sensing line to the primary side of a spark coil, and then set the calibration PPR value for
your spark configuration, using directions for the CALIBRATIO option.
Once upon a time, there was just one configuration: a spark coil, a distributor, and then wires from the
distributor cap to the individual sparkplugs. If your car is like this, use the table below:
FOR "CLASSIC" ONE-IGNI ION-COIL ENGINES
IF YOU HAVE ONE COIL PER PLUG CONNEC O ANY SPARK COIL PRIMARY
IF YOU HAVE ONE COIL PER WO PLUGS CONNEC O ANY SPARK COIL PRIMARY
DIESEL ENGINES
Modern diesel engines usually have camshaft sensors or electronic injector pumps. If there is one
injector per cylinder, the signal from the pump drive will be 1/2 PPR. Similarly, if there is a camshaft
sensor signal the signal will be ½ PPR. Set the calibration at a reading of 500.
If there is no electronic cam sensing or fuel injection in your diesel engine, the procedure is more com-
plex. A signal can be obtained from the alternator by attaching a wire directly to the winding of the sta-
tor before it goes to one of the rectifier diodes. This signal will be proportional to engine speed, but the
proportionality must be learned. See the TACH CALIBRATIO procedure for details, using meter setting

SPECIAL SCALING FUNC IONS
Several Proparts meters require a setup procedure to define the kind of input they are looking at.
These are:
achometer – the user needs to tell it the number of “pulses per revolution” (PPR) coming into its
sense line. This number varies widely between makes and models of cars. The default value is an
eight cylinder engine with 4 PPR. The program setting is 4000RPM.
Speedometer – the user needs to tell it the number of pulses that come in, per mile of travel.
O2 sensor – the user needs to tell it whether the sensor is narrowband (with a 0-1 volt output) or a
wideband sensor with a 0...5 volt output Once the meter is hooked up, the procedures are relatively
painless.
O SE UP SCALING
Turn the ignition off and on again to assure that the meter is in a reset state.
If it starts up with the face changing color and the pointer going up and down continuously, the meter
is in demo mode. Press the center button before continuing.
ACH CALIBRA ION
First read the section on TACHOMETER SE SE LI E ATTACHME TS A D METER SCALI G in order to
find out how you need to set the meter. When you have figured out what PPR setting you are to use,
press the Mode and Up buttons simultaneously for five (5) seconds. The dial will flash blue rapidly.
This places the meter in the scale-setting mode. Use the Down and Up buttons to move the meter
pointer to the appropriate RPM reading according to the table. If you have selected an “RPM” reading
of 1000 or up, just press the center button to leave the scale setting mode and resume normal
operation with the selected scaling.
If you were forced to use the alternator as a signal source, you selected an RPM of “0.” ow you must
tell the motor when it is operating at 2000 RPM. Using a strobe light, slowly increase the engin
speed till you hit 2000 RPM. The meter will read some nonzero value that increases and decreases
with engine speed, but it will not be accurate. While the engine is running steadily at 2000 RPM, press
the mode button. Your meter is calibrated. You can verify the setting by turning the ignition switch off
and on again, starting the car, and checking whether the idle speed on your tachometer is the same as
the speed you measure with a strobe light.

PROGRAMMING STARTS IN
MAIN MENU
PRESS PROGRAM BUTTON ONE (1) AT A TIME IN THE MAIN MENU MODE.
1 NORMAL OPERATION:
On power up, the meter usually starts in NORMAL operating mode. The Tachometer will read en-
gine’s RPM. Press the center “mode” button to advance to 2 PEAK PLAYBACK
2PEAK PLAYBACK:
Reads the highest value displayed on the meter since the last time the “Peak” value was displayed.
Pressing the “Down” or “Up” control button will control the gauge dial illumination. Press the center
“Mode” button to advance to 3 HIGH RACING RED-LINE SETTING
3HIGH RACING RED-LINE SETTING:
Sets the point at which “HIGH” warning RED-LINE is reached for that specific gauge. The “Down and
“Up” buttons will move the dial pointer to select “Maximum RED-LINE”. During normal operation the
gauge constantly monitors the sensor value and compares it to the “HIGH” RED-LINE. If the
threshold is exceeded, the red “HI” indicator is turned on and an output signal generated. Press the
center “Mode” button to save the setting and advance to 4 LOW RACING YELLOW-LINE
SETTING
4LOW RACING YELLOW-LINE SETTING:
Set the Minimum RED-LINE: Sets the point at which “LOW” warning threshold is reached for that
specific gauge. The “Down” and “Up” buttons will move the dial pointer to select the LOW
RACING YELLOW-LINE SETTING. During normal operation the gauge constantly monitors the
sensor value and compares it to the “LOW” threshold. If the sensor value drops below the threshold,
the yellow “LOW” indicator is turned on and an output signal generated. Press the center “Mode”
button save the setting and advance to 5 COLORSCHEME
5COLORSCHEME:

TACHOMETER SENSE LINE ATTACHMENTS AND METER SCALING
GASOLINE ENGINES
The WHITE/DIMMER circuit must be installed and supply 3 to 12vdc before the PPR can be
progammed
Attach the sensing line to the primary side of a spark coil, and then set the calibration PPR value for
your spark configuration, using directions for the CALIBRATION option.
Once upon a time, there was just one configuration: a spark coil, a distributor, and then wires from the
distributor cap to the individual sparkplugs. If your car is like this, use the table below:
FOR “CLASSIC” ONE-IGNITION-COIL ENGINES
IF YOU HAVE ONE
COIL PER PLUG CONNECT TO ANY SPARK COIL PRIMARY
IF YOU HAVE ONE COIL PER TWO PLUGS CONNECT TO ANY SPARK COIL PRIMARY
DIESEL ENGINES
Modern diesel engines usually have camshaft sensors or electronic injector pumps. If there is one
injector per cylinder, the signal from the pump drive will be 1/2 PPR. Similarly, if there is a camshaft
sensor signal the signal will be ½ PPR. Set the calibration at a reading of 500.
If there is no electronic cam sensing or fuel injection in your diesel engine, the procedure is more com-
plex. A signal can be obtained from the alternator by attaching a wire directly to the winding of the sta-
tor before it goes to one of the rectifier diodes. This signal will be proportional to engine speed, but the
