5 Mount the optical sensor to the magnetic base. The base is adjustable to allow the
sensor to be oriented in many directions.
6 Attach the other end of the optical sensor lead into the optical sensor.

1 Disconnect the negative battery cable. This will prevent the vehicle from starting.
2 Mount the optical sensor (attached to the magnetic base) in a location where the
red lens has an unobstructed view of the reflective tape.
Use the magnetic base on/off switch to secure the assembly to a stationary metal
object.
3 Connect the negative battery cable.
4 Verify the optical sensor is working.
Note: At this point you will need to skip to “Running WinPEP” on page 1-6 and
follow those instructions for making a run. These instructions will allow you to
use the tachometer gauge to verify whether the optical sensor is functioning
properly. Return to this section to adjust the optical RPM sensor as needed.
5 Verify the hardware stack is on.
6 Verify the optical sensor cable is plugged in to the RPM module and the power
lead from the cable is connected to the CPU module. Refer to Figure 1-3.
Note: Dynojet recommends you ground the vehicle to the dyno for the
electronics to function properly.
