STEINBAUER application
Doosan DL350-5 Power Module
9.3L DC09 XPI Tier 4 / Tier 4F
Increase from 271 BHP to 325 BHP and from 1,275 Nm to 1,530 Nm — without ECU remapping.
STEINBAUER performance module for the Doosan DL350-5 9.3L DC09 XPI Tier 4 / Tier 4F, 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 through demanding work cycles can reduce the need for excessive engine speed under load, which may support more efficient fuel use.
Actual fuel consumption depends on vehicle load, operating conditions, terrain and driving or operating style.
