New Holland CR Series CR7.90 8.7L I6

Chip tuning for New Holland CR series CR7.90 is a recalibration of the engine’s electronic control unit (ECU) – the CR7.90 8.7L I6 engine – developed to improve the tractor’s efficiency and reliability in demanding agricultural environments. Modern diesel engines, controlled by the Boch EDC7UC31 ECU with an ECU Micro processor, require precise adjustment to achieve optimal performance. Reprogramming the ECU allows the engine’s operation to be adapted to specific operating conditions, ensuring maximum drawbar pull under load.

During chip tuning, parameters such as fuel injection, boost pressure, and other factors affecting power and torque are adjusted. A key aspect of the process is the ability to disable the EGR and DPF systems, which reduces engine load and extends its service life, particularly when operating in dusty conditions. At AutoChip.lv, we analyze data from the ECU and develop individual solutions aimed at ensuring stable tractor operation throughout its service life.

Optimizing engine performance not only increases its output but also eliminates errors and limitations imposed by the manufacturer. This provides smoother and more predictable operation of the equipment, reducing the risk of failures and extending the intervals between maintenance services. Chip tuning for New Holland CR series CR7.90 is designed to enhance the efficiency and durability of your tractor.
