Cummins Calterm 4.01v For All Models Calterm v4.0.1 is the Latest Engineering Tool For All Models Of Cummis Engines Calterm 4 is an engineering development tool used to monitor Electronic Control Modules for Cummins engine systems and to alter the calibration data contained therein. Calterm 4 is designed to modify fueling calibration parameters and feature settings in an engineering development and test environment. The development process for electronic engines requires PC support tools which interface to the electronic subsystem, and its various feature sets. Calterm is used to increase the productivity of the engineers developing electronic engine features by providing diagnostics, simulation, and value manipulation capabilities for Electronic Control Modules (ECMs). As is the case with most support tools, Calterm 4 attempts to work with all of the features in the ECM. However, this superset of functionality is not always feasible given the rapid growth and change being experienced in Cummins’ electronic systems. As a way to try to give the most support to every electronic engine program, this tool will provide a base set of capabilities which will work on any ECM following the CORE Tools Interface standards. Customized or unique capabilities will then be added, as they are needed.
