Before Ordering determine which size diameter trigger disk is needed for your car. Select 1.0" or 1.25" diameter so that the sensor can read the wholes in the trigger disk. Trigger disk size is based on the constraints of your rear pod uprights. Generally the 1.0" trigger disk is used on electric cars and nitro cars. Step 1: Install trigger disk on axle between rear pod uprights. Picture at left displays a 1.25" trigger disk and sensor mounted to lower chassis plate with supplied bracket. The trigger disk is mounted to the rear axle with 4-40 set screw in similar manner of a rear wheel hub or belt pulley. Step 2: The infrared sensor and bracket are mounted to your chassis by using the supplied bracket. The sensor with bracket is mounted to the car chassis in a manner so that the U-shaped sensor will straddle each side of the trigger disk. Determine where on the car chassis the computer will be mounted, the location determines the sensor with cable length (part # oc-sc05, oc-sc15 or oc-sc25) needed for your setup. If computer is to be mounted at rear of car then a 5" sensor wire assembly (part # oc-sc05) can be utilized. When mounting the computer near front of car chassis a 15" or 25" sensor wire assembly can be utilized. |

Most cars can accommodate the computer in the rear pod area or mid to front chassis area. |

Turn computer to Race mode and wait for led to flash red once then flash green quickly. Spin wheels by hand, computer will record movement. When recording stops led will flash red every 5 seconds. |
