The BLAG technical database contains 214 Caterpillar references in heavy-duty and industrial applications. This curated page makes the coverage useful without generating one thin URL for every vehicle record.
How to use this Caterpillar coverage
Find the model family below, then confirm the exact engine, generation and ECU through the interactive configurator. Database presence is not a promise that every software version supports the same service. Final feasibility depends on the ECU, HW/SW, original read, machine configuration and intended permitted use.
The calibration brief should describe load, transmission, hardware, current DTCs and the result required. For sector context, read the truck ECU tuning page.
