Increased performance where applicable for stronger acceleration and improved working capability.
STEINBAUER application
Application in development
Valmet Komatsu Forest 931.1 Power Module
7.4L Tier 3B
Increase from 259 BHP to 325 BHP and from 1,070 Nm to 1,338 Nm — without ECU remapping.
A STEINBAUER application is currently in development for the Valmet Komatsu Forest 931.1 7.4L Tier 3B. Register your interest and STEINBAUER UK can contact you when development and final validation are complete.
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.

STEINBAUER Technology
- External ECU technology — Works alongside the original engine management system without permanently rewriting the factory ECU software.
- Load-dependent performance — Additional power and torque are delivered progressively as engine demand increases.
- Application-specific calibration — Developed specifically for the individual engine and application rather than using a generic universal setting.
Agricultural performance
More about STEINBAUER tractor tuning →
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.
