Manitou MLT 840 137 Power Module

4045 PWX Tier 3B

Increase from 137 BHP to 172 BHP and from 515 Nm to 644 Nm — without ECU remapping.

STEINBAUER performance module for the Manitou MLT 840 137 4045 PWX Tier 3B, 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.

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.
Construction performance

Usable output for hard-working plant

Construction applications are developed around repeated digging, loading, lifting and hydraulic work cycles.

Digging More engine response when working under repeated excavation load.
Loading Stronger usable torque for loaders and material handling.
Hydraulic work Improved engine response through demanding hydraulic cycles.
Working range Performance concentrated where construction machinery operates.
