All Data measured at wheels on Superflow Dyno

FCA Ecodiesel V6_Full load curves OEM vs GDE Hot v2

As indicated, the Green Diesel tune achieves a broad gain over the torque curve giving the driver a huge improvement in the drivability and “seat of the pants” feeling of the vehicle. Coupled with the transmission tune, it is like buying a new vehicle.

Also, the max power of the engine is achieved as soon as possible with the hot tune and maintained over a plateau as wide as possible (roughly 300rpm). This gives a noticeable gain in the performance feeling of the engine while accelerating.

Benefits and Features of the GDE tunes for the EcoDiesel V6s (Ram 1500 and Jeep Grand Cherokee)

GDE Combustion Concepts

  • Optimized fuel economy (2-4mpg* improvement) both while driving and at idle
  • Engine longevity increased
  • Transient management of injection timing to reduce combustion noise
  • 75% reduced soot formation in cylinder, leads to more miles between dPF regens

Better transient engine performance

  • Faster time-to-torque giving elevated customer confidence in the driving experience
  • Required accelerator pedal effort to hold constant speeds is reduced
  • Engine performance is improved over stock from sea level to 12000ft elevation
  • At 5000ft, 0-60mph is 1.5s faster; at 9000ft, 0-60mph is 0.75s faster

Refined cruise control operation (only for vehicles without adaptive cruise control)

  • Retuned speed control for improved fuel economy
  • Better gear holding during accelerations and uphill driving
  • Lower possible set speed (15mph instead of 25mph, can resume from 5mph)
  • Faster buttons' response

Superior management of grille shutters

  • Shutters will now function in cold ambient temperatures for better warmup performance
  • More expansive criteria for closing the shutters

Two-footing driving is now permissible

Improved operation of three-way coolant valve to give engine warm-up benefits

Eliminated high pressure pump noise for MY15 and newer vehicles

More intuitive driver indications

  • Glow plugs indicator will be displayed only when glow plugs are actually on

Improved cooling fan control

  • Fan will now run for a certain amount of time after shut-down to cool down the engine and exhaust system
  • Activates if either the regen is still active when the engine is shut off, or if the exhaust temps are above a prescribed limit
  • Earlier activation based on coolant temp while driving to keep engine and oil cooler

Refined Transmission control

  • quicker shifting, more intuitive gear selection
  • More use of converter lockup to reduce trans fluid temps and improve fuel economy
  • Holds gear better at speed

Tune Options

  • Engine braking while coasting
  • "Regeneration in progress" message activated for all regenerations
