Engine family John Deere 4.5L →

STEINBAUER performance module for the John Deere 450J Crawler Dozer 4.5L PowerTech M 4045 Tier 4i, 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 — Additional usable torque during sustained heavy-duty operation can reduce reliance on higher engine speeds, which may support more efficient fuel use.

Actual fuel consumption depends on vehicle load, operating conditions, terrain and driving or operating style.
