In the mid 80’s, Mitsubishi Motors of Japan and the American car company Chrysler joined forces to create Diamond-Star Motors. Originally this organization was developed to go around the laws restricting Japanese imports at the time, DSM products, in particular the Mitsubishi Eclipse, would go on to become much sought after by car enthusiasts, who would refer to these cars as DSMs. Today Mitsubishi has gained full control of the operation and the entity was renamed to Mitsubishi Motors North America, but that is not why you are here. You own, perhaps even race, one of these classic cars and are looking for a 2G DSM Datalogger for Eclipse for the Eclipse.

The Scanmaster 2G DSM Datalogger is the tool you need. It is a portable scan tool for monitoring data that is retrieved from the ECU (Engine Control Unit). The 2G DSM Datalogger is intended to be permanently mounted so that it is always available for monitoring the state of tune of the engine. The Scanmaster 3i 2G DSM Datalogger has a number of special features that set it apart from the competition.

The Scanmaster 3i retrieves data from the ECU as fast as the ECU can send it, however some data is more critical since it changes rapidly (such as O2 voltage) and is scanned more often. There are also many data items that change slowly, but are very important to monitor (such as coolant temperature, trim values) and can be scanned less often. The Scanmaster 3i Priority Manager handles this and provides large amounts of data without sacrificing the update speed of the critical data.

The Scanmaster 3i provides a serial port for logging data to a PDA or laptop. The output is at high baud rate so the 2G DSM Datalogger will never miss any data. On the rear of the unit is a 3.5mm jack for connecting two 0-5 volt external signals. These signals can be displayed on the Scanmaster 3i as well as logged to a PDA/PC. If a wideband Air/Fuel signal is connected, the Scanmaster 3i can be configured to display that Air/Fuel ratio as the default display. The analog data can be displayed as boost (2 bar, 2.5 bar, 3 bar) and Air/Fuel ratio.

The Scanmaster 3i 2G DSM Datalogger reads the vehicle speed sensor and calculates vehicle speed, acceleration, and performance from the data. If the vehicle speed input is not connected the Scanmaster 3i will use the speed data available through the OBD-II connection. In this case, acceleration data cannot be calculated.
