Factory signal received
The STEINBAUER module reads the original injection command from the factory engine-management system.
Intelligent engine technology
Precision performance without permanently changing the ECU.
STEINBAUER performance modules increase usable power and torque by precisely optimising injection duration, while leaving factory ECU programming and common-rail pressure unchanged.
How STEINBAUER works
More performance through precise fuel-injection control.
A STEINBAUER module works with the original engine management system and adjusts the duration of the injection signal on a diesel engine. The required additional fuel is introduced at the end of the existing injection event, rather than by altering factory injection timing.
Because the original ECU software is not rewritten, the engine management system continues to supervise its normal operating limits, safety parameters and protection strategies.
The result is a removable, application-specific approach that keeps the original ECU architecture intact. The dedicated Tuning Methods page explains the technical differences between STEINBAUER, pressure-based tuning boxes and ECU remapping in more detail.
The process
Four stages of controlled performance enhancement.
Operating conditions assessed
The module responds according to engine speed, demand and the application-specific calibration.
Injection duration optimised
Additional pulse width is applied at the end of the existing injection event without changing timing.
More usable output
The engine delivers stronger torque and power where required, while remaining under factory ECU control.

Diesel engine operation only
Injection-duration control in motion
STEINBAUER works with the original engine-management system and, on compatible diesel applications, extends the main injection duration when additional performance is required. The original ECU remains in control of injection timing and engine-protection strategies.
Illustrative operating principle: exact activation points, injection duration and control characteristics vary by engine and application.
Different tuning approaches
An overview here. The detailed comparisons have their own pages.
Factory control remains
The original engine-management system stays in charge.
Protection strategies
The factory ECU continues to supervise operating limits and engine-protection functions.
Original diagnostics
The vehicle retains its factory diagnostic system and original software architecture.
Application-specific development
Each compatible application is developed around the relevant engine and injection system.
