A STEINBAUER application is currently in development for the John Deere 548G-III 6.8L PowerTech 6068T Tier 2. Register your interest and STEINBAUER UK can contact you when development and final validation are complete.

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 maintain performance through sustained harvesting, forwarding and extraction work without relying 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.

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.
Forestry performance

Developed for sustained forestry load

Forestry applications focus on pulling performance and response during harvesting, forwarding and extraction cycles.

Extraction Stronger pulling performance when moving timber under load.
Gradients More usable torque on steep and difficult ground.
Hydraulic cycles Improved response during repeated harvesting operations.
Sustained load Progressive output for long, demanding working cycles.
