As presented, the GDE Tune achieves huge gains along the torque curve for improving the performance gains. GDE also achieves engine power above 160hp from 3300 – 4000 rpm which improves the pulling power when accelerating for a smooth, linear feeling.
Declared gains are 70 lb-ft (at 2350rpm), 20 hp @ 4000rpm, and 24hp @ 3500rpm. These performance improvements translate to approx. 1-1.2sec faster in a 0-60mph acceleration (from standing start).

Real-world Consumption Improvements

One of the main goals of the GDE tuning is to achieve a cleaner combustion output that results in keeping the engine cleaner internally and gaining fuel economy. These changes translate into a direct fuel cost savings to the customer which not only saves money while making the vehicle more fun to drive, but also gives a payback to the cost of the tuning. Characterized over a repeated drive cycle, the GDE tune delivers consistent and proven gains in fuel economy. Depending on your drive cycle profile, improvements are in the range of 4-7 miles/gallon.

A fleet of beta testers ran for 3-4 months before public release of the tune to validate the above claims and over 20000+ miles all data is confirmed.

Benefits and Features of the GDE tunes for the VW 2.0L CBEA-CJAA engines

GDE Combustion Concepts

  • Optimized fuel economy (4-7mpg* improvement) while driving
  • Reduced engine soot (in exhaust, in intake manifold, and in oil)
  • Engine longevity increased due to cleaner combustion

Improved idle management

  • Warm engine idle speed lowered to 750rpm for fuel consumption improvement (40%)
  • Cold engine idle speed increased for faster vacuum build-up for turbo response
  • Modified idle control during coasting to eliminate unnecessary fuel burn
  • More responsive idle torque controller to make easier launching the vehicle on the low idle governor instead of needing to apply accelerator

Activated exhaust temperature limitation strategies for engine hardware protection

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

Modified high pressure fuel pump control strategies

  • Lower pump hardware noise (due to filling volume in pumping chamber)
  • Decreased fuel heating when not needed

Two-footed driving permissible in all conditions (no torque cut)

* 4-7 mpg fuel economy improvement is an estimate based on engineering tests and data collected: your personal gain might be higher or lower depending on your usage and driving habits.
