**Komatsu Wheeled Harvester 931XC – Chip Tuning for Reliable Operation**

The comfortable and efficient operation of forestry equipment directly depends on the stability of the 7.4-liter Komatsu 931XC engine. This six-cylinder unit, controlled by a Boch EDC17CV54 ECU with a TC1767 processor, requires precise adjustment for operation in demanding conditions. Chip tuning allows the engine’s performance to be adapted to specific tasks and operating conditions, ensuring maximum traction and productivity.

The ECU remapping process involves analyzing current engine parameters, adjusting fuel maps, ignition timing, and other critical settings. At AutoChip.lv, we focus on optimizing engine performance to achieve more efficient fuel combustion and increased torque – in this case, up to 1100 Nm – which is crucial for harvester operation.

For tractors operating under high loads, the ability to disable EGR and DPF systems is an important consideration, reducing engine stress and contributing to its longevity. It is also possible to remove errors and limitations programmed into the ECU to ensure stable operation.

Our goal is not simply to increase power, but to ensure the reliability and lifespan of the Komatsu Wheeled Harvester 931XC engine, as well as improve its throttle response.
