Auto Meter offers several options that can be included with your computer package. Options typical in a sportsman application include the following:

• 8 EGT's (Exhaust Gas Temperature Probes and Transducers)
• Additional Pressure Sensors
• Temperature Sensors
• Voltage Reducer
• Vacuum Sensor
• Shock Travel Sensor. This system is designed to monitor the suspension movement at launch as well as down the track.

Equipment for something like a Pro Stock (car or truck) application will typically include the following additional equipment:

• Input Shaft Sensor (Lenco). This sensor determines the speed of the input shaft. It's a must have if you want to know what is really going on inside the bell housing.
• 25 PSI Pressure Sensor and Cable for Regulated Fuel Pressure ("Cable" is a data transmission harness)

A number of different RPM sensors are available for the Data Logger. Typically, you can measure input shaft RPM (currently available for Lenco style transmissions), engine RPM and driveshaft RPM. Engine speed is picked up by way of the ignition tach output terminal on an ignition control box. The input shaft speed sensor is picked up via the "candlestick" on a Lenco while the driveshaft speed is picked up with a rear end sensor such as the unit shown in this photo. Auto Meter offers rear end collars for 12-bolt Chevrolets as well as large and small pinion Ford 9-inch rear axles. Basically, a collar is installed on the rear end yokes and a series of magnets pick up the speed of the yoke. An RPM sensor or pickup is installed on the housing. This arrangement is similar to a crank trigger installation on an engine.
