SCR DPF EGR Off for FSK FORETMAT

Bypass Emission Failures with File Services for FSK Forestry Machines

The FSK 4625 skidder is powered by a John Deere engine and controlled via a Phoenix L33 ECU. Like many forestry machines, it includes emission control systems such as SCR, DPF, EGR, and AdBlue/DEF injection, along with additional components like DPF differential pressure sensors, exhaust gas temperature sensors, and aftertreatment control modules (ACM) — all of which are prone to faults and lead to machine derating, fault codes, or forced idle modes.

Our File Services for FSK provide full ECU recalibration to cleanly deactivate these systems, including all emission-related dependencies. In addition to the 4625, we support all other FSK machines for emission system removal, ensuring consistent reliability across your entire fleet.

With our Calibration Files for FSK, you can prevent unwanted downtime, eliminate error-prone components like NOx sensors, AdBlue injectors, or DOC catalysts, and keep your forestry operations moving without disruption.

All models of the brand might not be listed due to the extensive scope of work, but we can operate on 95% of the brand's fleet.
ECU & Electronic Module Reading/Writing:
Some ECUs cannot be read or written due to new security measures (e.g. Bosch MD1 after 2021), some ACM... We have created a help page to explain why some modules are currently unavailable for programming.
