FCA EcoDiesel 3.0L V6 Tune Details

 

Engine Output Comparison

Production Hot Tune
250 hp @ 4000 rpm 285 hp @ 3600-4000 rpm
570 Nm @ 2000 rpm 635 Nm @ 2000-2400 rpm


OEM declared output is only available for 90s; then a lower continuous output is available 

  

3.0 ECO diesel FCA Chart

As indicated above, 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.

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 400 rpm). This gives a noticeable gain in the performance feeling of the engine while accelerating.

Real-world Consumption Improvements

As much as everyone likes to bench race about how much more power their engine makes compared to another one, what really matters to everyone's bottom line is how much farther they can go with the same amount of fuel. Here at GDE one of our most important goals is to make the engine as efficient as possible to give you the customer the best possible fuel economy and also DEF (Diesel Exhaust Fluid) economy too. During the course of our tune development, we characterized three different cycles (pure city, mixed driving, and freeway) in order to have a comparison as un-biased as possible. In the table below are the high-level results of the cycles:

Route Tune Fuel Economy (l/100km) DEF Consumption (kml / DTE) Regen. Interval (km)
City Cycle GDE 8.40 884 / 25102 485
OEM 10.45 607 / 18390 58-89
Mixed Cycle GDE 7.30 677 / 20590 756
OEM 9.05 545 / 15475 85-204
Highway Cycle GDE 7.45 539 / 16325 958
OEM 8.55 332 / 10063 668

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

  • GDE Combustion Concepts
    • Optimized fuel economy (1.5 - 2.1 km/l* improvement) both while driving and at idle
    • Reduced engine soot (in exhaust, in intake manifold, and in oil)
    • Improved DEF consumption
    • Engine longevity increased
    • Transient management of injection timing to reduce combustion noise
  • Enhanced DPF management
    • Updated soot models and regeneration triggers based on GDE Combustion Concepts - longer intervals between regenerations
    • Refined regeneration control for better soot burn, 1200 km or more in certain conditions
  • 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 4000 m elevation
    • At 1500m, 0-100 km/h is 1.5s faster; at 2000m, 0-100 km/h 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 (25 km/h instead of 40 km/h, can resume from 8km/h)
    • 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
  • Improved operation of three-way coolant valve to give engine warm-up benefits
  • Two-footing driving is now permissible
  • Eliminated high pressure pump noise for MY15 and newer vehicles
    • Also applicable to MY14 vehicles that have been recently re-flashed
  • More intuitive driver indications
    • "Engine Power Reduced" warning for hot oil temps activated at lower temp
    • 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
  • Inducement improvements: torque limitation instead of no-start, activates after one key cycle instead of immediately.
  • Disabled low voltage charging mode in order to properly drive electrical accessories in all conditions

*  1.3 - 2.1 km/h fuel ecnomy improvement is an estimate: your personal gain might be higher or lower depending on your usage and driving habits.

Tune Options

  • Engine Performance Curve
  • Eco vs Hot tune (Hot tune has higher full-load output, higher allowable exhaust temps)
  • Engine braking while coasting
  • "Regeneration in progress" message activated for all regenerations
  • Custom requests!
