We calibrate the firmware of Bison ATV 300 and Bison ATV YK450 ATVs with Delphi MT05.3 ECUs. We successfully implemented the Stage 1+ solution, removing the speed limit and engine RPM cutoff for the Bison YK450 ATV.

We offer DPF and EGR system deactivation for Zoomlion tractors and other equipment equipped with the Bosch EDC17CV43 ECU. A Stage 1 power boost tuning is also available.

We professionally customize firmware for the new Hisun Guardian ATV series with the Bosch MED17.8.8 ECU. We offer Stage 1, Stage 1+ (Stage 2) settings, as well as adjustable maximum RPM and maximum speed limits in L and H modes.

We calibrate the firmware for the new Linhai Landforce series ATVs with the Bosch MED17.8.10 ECU. We've implemented the Stage 1 VMAXoff solution for the 2025-2026 Landforce 650 ATV with electronic throttle.
