Tuning Overview

It is important to know that we tune the engine through the actual vehicle ECU.

Calibration General

When calibrating a diesel engine or transmission using the proper tools to measure pressures, temperatures, etc. is vital to ensuring safety and emission limits are maintained.

Below list some of the parameters we modify (based on application and software) to improve the engine efficiency:.

Fuel Rail Pressure
  • Better Fuel delivery
  • Increased power
  • Reduced soot
Boost Pressure
  • Increased performance
  • Less visible smoke
  • Reduces fuel consumption
Main Injection Timing
  • MAXIMIZES fuel economy
  • Helps lower exhaust temps
Pilot injection Timing/Quantity (on common rail engines)
  • Maintain low engine noise
  • Aids in reducing fuel consumption
  • Reduce soot formation
  • Controls cylinder pressure rise
Governing Systems
  • Enhance driveline stability
  • Reduce vibration
  • Better throttle tip-in response
  • Refined pedal mapping
Tuning changes vary based on application. The goals remain the same; maximize fuel economy, improve drive ability and performance.
