STEINBAUER application
BMW 340i F30 Power Module
3.0L B58 (Past-2019)
Increase from 322 BHP to 386 BHP and from 450 Nm to 540 Nm — without ECU remapping.
STEINBAUER performance module for the BMW 340i F30 3.0L B58 (Past-2019), 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 — More usable torque can help the vehicle pull strongly at lower engine speeds with less throttle demand, which may support improved fuel efficiency in suitable driving conditions.
Actual fuel consumption depends on vehicle load, operating conditions, terrain and driving or operating style.
