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.
STEINBAUER also avoids increasing common-rail pressure. This provides a controlled, removable alternative to a permanent ECU remap.
The process
Four stages of controlled performance enhancement.
Factory signal received
The STEINBAUER module reads the original injection command from the factory engine-management system.
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
Variable injection-duration control
On compatible diesel applications, STEINBAUER leaves the injection event completely standard at lower engine demand. From around 70% engine load, the module begins to progressively extend the main injection duration as demand increases. The original ECU remains in control of injection timing, while pre-injection and post-injection signals remain unchanged.
Engine load
≈ 70%
progressive extension begins
Main injection duration remains standard. No additional STEINBAUER injection duration is applied.
STEINBAUER progressively extends the main injection duration according to engine demand and the application-specific calibration.
Injection timing, pre-injection and post-injection signals remain under the control of the original engine-management system.
Illustrative operating principle: the exact activation point, injection duration and control characteristics vary by engine and application. The animation is for demonstration and simulation purposes only.
STEINBAUER compared
A removable module rather than a permanent software change.
| Feature | STEINBAUER module | Conventional ECU remap |
|---|---|---|
| Factory ECU software | Remains unchanged | Software calibration is rewritten |
| Common-rail pressure | Not increased by the module | Depends on the calibration strategy used |
| Injection timing | Left under factory ECU control | May be altered within the remap |
| Removal | Module can be removed | Original software must be restored |
| Transferability | May be reusable on compatible applications | Vehicle-specific software change |
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.
