Increased performance where applicable for stronger acceleration and improved working capability.
STEINBAUER application
Application in development
MAN D0834 LFL66 Power Module
4.6 EUR6
Increase from 148 BHP to 177 BHP and from 570 Nm to 684 Nm — without ECU remapping.
A STEINBAUER application is currently in development for the MAN D0834 LFL66 4.6 EUR6. 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 — Stronger usable torque can help maintain progress at lower engine speeds with less unnecessary revving, which may support improved fuel efficiency in suitable operating conditions.
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.

Built for loaded truck operation
STEINBAUER truck applications focus on usable torque and progressive performance during laden running and sustained commercial operation.
Loaded running
Stronger usable torque when the vehicle is fully laden.
Gradients
Improved pulling performance on hills and demanding routes.
Lower-rev performance
More usable torque can help maintain progress at lower engine speeds, reducing the need for unnecessary revving.
Fleet support
