STEINBAUER performance module for the Massey Ferguson MF 6485 6.6L Sisu 66CTA [non CVT] (CR), designed to provide increased power and torque while retaining the original ECU programming and factory engine safeguards.
Key benefits
- Up to +25% power and torque increase, depending on application.
- No ECU software overwrite — the STEINBAUER system works alongside the original engine management.
- Injection duration module developed to add performance without generic one-size-fits-all mapping.
- Removable solution that can be removed if required.
- Application-specific development for the individual engine and vehicle or machine application.
- Efficiency — Additional torque can help maintain performance under load without relying on excessive engine speed, which may support more efficient fuel use during field work, PTO operation and transport.
Actual fuel consumption depends on vehicle load, operating conditions, terrain and driving or operating style.
