The AutoAgent connects to the vehicles via the OBDII-port and broadcasts a Wi-Fi access point (AP) which allows a wireless connection to the vehicle using any iOS device (Android support coming soon – will also support the inexpensive Android monitors). By launching the free EZ LYNK application on an iOS device, engine data is seamlessly streamed to the phone or other smart devices. The AutoAgent also has the capability to reflash vehicle system controllers with ECU profiles shared by technicians.

Technicians will quickly learn to appreciate the EZ LYNK Cloud where they can easily manage customers/vehicles and all the data associated with them (datalogs, engine profiles, vehicles information). Transferring engine profiles via USB connection, SD card or e-mail are now a thing of the past as technicians have the capability to share engine profiles with the click of a button to completely eliminate user-error from the equation.

On the other side of things, the end-user can conveniently share datalogs and other vehicle information to any technician with the touch of a finger without even leaving the driver seat. Datalogs can be quickly started and stopped from the main gauge display screen and bookmarks can be added to draw interest to the specific points of a datalog if desired. A graphical web-based datalog viewing solution will soon be incorporated into the EZ LYNK Cloud as well.

A fully customizable user interface allows the end-user to create a gauge interface that suits their particular needs. Technicians can also create default PID configurations that are automatically loaded during a reflash procedure to further assist in the troubleshooting and diagnostic process.

EZ Lynk requires use of a Apple or Android device to function, Must have iOS 8.0 or higher, iPad, iPod touch, iPhone

Duramax Glow Plugs Operation Glow Plug Relay

Cold Weather Starts and Glow Plugs Glow Plug System Description Duramax diesel engine, air alone is compressed in the cylinder. Then, after the air has been compressed, a charge of fuel is sprayed into the cylinder and ignition occurs, due to the heat of compression. Eight glow plugs are used as an aid to starting. The glow plug initial ON time will vary based on the system voltage and temperature. Lower temperatures cause longer ON times all the times. The ECM provides glow plug operation after starting a cold engine. This post-start operation is initiated when the ignition switch is returned to Run, from the Start position. This operation helps clean up excessive white smoke or poor idle quality after starting. Control of the instant start system, glow plugs is determine by an electronic glow plug control unit and 4.7 volt glow plugs, requiring 2 seconds to heat up to 1,000°C (1,832°F) .
