INSITE is the engine tool most heavy-duty shops add once they service a meaningful share of Cummins powered trucks. Cummins describes it as PC software that performs engine diagnostics and displays electronic engine information, with step-by-step diagnostics, built-in engine drawings and schematic diagrams. It shows trip information, adjusts parameters and reviews and clears faults. Both the Lite and Pro versions include troubleshooting help, wiring diagrams, sensor location diagrams and a database for engine and trip records that can be reused as programming templates, and both include all automotive and industrial ECM applications. Cummins states that INSITE Pro is the only version that includes and supports ESDN. The limits are scope and buying: it only covers Cummins engines, and Cummins' pages send buyers to a local distributor rather than listing a price, so you will need a quote for the Lite or Pro license.
