Cummins Calterm is a specialized tool designed for high-level diagnostic control, parameter editing, and ECM programming on Cummins electronic engine platforms. The software allows users to view real-time data, capture logs, adjust operating limits, modify fuel and torque maps, and upload revised calibration files to supported controllers. Calterm is commonly used in testing environments, prototype development, emissions research, and fleet performance optimization where access to raw ECM data and calibration controls is required. Unlike standard service software, it supports low-level flashing, table editing, hex-level access and advanced communication modes for engines used in on-highway, industrial, agricultural, and power-generation applications.

INSITE 9.0 is the OEM service software developed by Cummins for maintenance, troubleshooting, and configuration of Cummins ECM-based engines. The program enables technicians to read active and inactive fault codes, reset engine parameters, perform functional tests, monitor real-time data, and load or update calibration files. It supports a wide range of Cummins engine families used in on-highway trucks, buses, construction equipment, agricultural machinery, power units, and marine applications. INSITE includes features such as data logging, trip information, injector cut-out testing, fuel system verification, cylinder balancing, and ECM programming support. It is widely used by commercial vehicle repair facilities, fleet service departments, and OEM-authorized repair networks for accurate Cummins engine diagnostics and configuration.
