Increased performance where applicable for stronger acceleration and improved working capability.
STEINBAUER application
McCormick CX 70L Power Module
3.3L Yanmar 4TNV98
Increase from 70 BHP to 86 BHP and from 244 Nm to 280 Nm — without ECU remapping.
STEINBAUER performance module for the McCormick CX 70L 3.3L Yanmar 4TNV98, 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.

Developed for real agricultural work
The additional output is aimed at the working range used for field work, PTO operation and transport rather than simply chasing a peak power figure.
Pulling performance
More usable torque for cultivation, gradients and heavy field work.
PTO performance
Additional output for PTO-driven implements and demanding operations.
Transport
Stronger response when towing, carrying loads or working on gradients.
PTO dyno testing
STEINBAUER UK can test suitable tractors before and after installation.
