PPr
PULSES PER REV MENU
Start by setting up your pulses per rev (PPr). Once this is
nished, the shift light is ready for use. There are two ways
to accomplish this; either by setting a PPr count (.5-6), or by
selecting the Program Mode (Pr9). The Pr9 mode lets you
dial the shift light to match your know engine RPM. This is
useful if you don’t know your PPr count or where the value
is different than .5-6 PPr count values.
1. Enter the PPr menu by pressing and holding the
programming button for two seconds.
2. Toggle through the available PPr options while in the
PPr Menu.
• PPr Options: 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 4.0, 5.0, 6.0
3. At the desired PPr setting, let the shift light time out for
ve seconds to save the PPr setting. Program mode (Pr9)
is explained in the next section.

PROGRAM MODE (Pr9)
Program mode (Pr9) will let you dial in the RPM on the LED
display to match your engine RPM. You can use this option
instead of the PPr for applications where the value is different
than .5-6 PPr or you don’t know the exact value. This lets you
dial in the shift light to match the engine RPM.
1. Start the engine and power up the shift light.
2. Press and hold the program button for 2 seconds to
select the PPr menu.
3. Bypass all available PPr settings by toggling to the last
option (Pr9) and hold the program button for 2 seconds.
4. You will see 1.00 (1,000 RPM) displayed on the screen.
Toggle the buttons up and down to have the LED read-
out match your engine RPM.
• This must be done with the engine running.
5. Once the LED readout matches the engine RPM, let the
shift light time out for 5 seconds to save the settings. The
LED will blink two times when it saves the setting.
SET SHIFT POINT MENU
1.
Press and hold the program button for 2 seconds to
select the Shift Point menu.
2. Use the buttons to toggle the RPM up or down to the
desired shift point.

can be selected in 10 RPM increments. (8.53=8,530)
3. When you have reached the desired shift point, let the
shift light time out. The LED will blink two times when it
saves the setting.
