Tool comparison
Jaltest AGV is Cojali's diagnostic solution for agricultural vehicles — tractors, harvesters, sprayers, telehandlers and implements — spanning many manufacturers through a single Jaltest interface and software. It reads and clears DTCs, shows live data, and performs component activations, calibrations, parameter settings, aftertreatment (DPF/SCR) regenerations, hitch/hydraulic and transmission functions, and ECU configuration. Agricultural dealers and independent workshops use Jaltest AGV to cover mixed brands without multiple OEM tools, aided by Jaltest's technical documentation and guided diagnostics for supported models, which is valuable for seasonal fleets running varied equipment.
INCAL is Cummins' distribution of ECM calibration files — the official calibration images and metadata used by INSITE (and Calterm) to reprogram Cummins electronic engines. Delivered as periodic releases, an INCAL package contains the approved calibrations for supported engine families, allowing technicians to update an ECM to a newer or corrected calibration during service. It is not a diagnostic interface itself but the calibration library the Cummins tools draw from. Correct INCAL access is required to flash genuine Cummins calibrations and to apply engineering (ECFG) updates to Cummins ECMs.
Jaltest AGV (Truck & Off-Highway Diagnostic, Cojali (Jaltest)) and Cummins Incal (Truck & Off-Highway Diagnostic, Cummins) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
