On Caterpillar machines the engine control unit is recalibrated from the machine's own original file. Services with verified solutions for Caterpillar in our library: Stage 1 Remap and AdBlue / SCR Delete.

The ECU models we work on in Caterpillar machines include CATERPILLAR A5E2V2I1, BOSCH EDC17C49, DENSO DCU and BOSCH EDC17CV54. The ECU type varies with model year and engine; send us a photo of the ECU label or the machine details and we will confirm exactly which services are possible.

The result depends on the machine and the engine. The calibration respects the limits of the engine, cooling and hydraulic system, and the original software is archived.
