VCDS (VAG-COM Diagnostic System) offers a powerful way to customize your Volkswagen or Audi vehicle, including adjustments to the Tiptronic automatic transmission. This article focuses on recoding the Tiptronic system using VCDS, specifically exploring coding “0000032” and its effects on torque converter behavior and shift patterns.
Understanding Tiptronic Behavior with Coding 0000032
Coding “0000032” has proven effective in optimizing Tiptronic performance for some users. Key observations with this coding include distinct differences in torque converter lockup and gear selection across various driving modes:
Drive (“D”) Mode:
In “D” mode, the torque converter tends to remain in slip mode for extended periods between shifts, leading to potential power loss and heat generation. This behavior is less than ideal for performance-oriented driving.
Sport (“S”) Mode:
While “S” mode exhibits quicker torque converter lockup compared to “D,” it seems to limit gear selection, potentially avoiding 5th gear. This characteristic makes “S” mode more suitable for city driving scenarios where higher gears are less frequently required.
Tiptronic Mode:
With coding “0000032,” Tiptronic mode demonstrates the most desirable torque converter behavior. Even in lower gears like 2nd, the torque converter locks up rapidly, minimizing slippage and maximizing power transfer. This results in improved acceleration and responsiveness. This mode allows for complete control over gear selection, further enhancing the driving experience.
Comparing Performance Across Modes
Real-world driving tests highlight significant differences:
-
Accelerating from 60 mph in “D”: The torque converter unlocks initially, causing a rise in RPMs before locking up again. This feels similar to a downshift, but might not actually be one.
-
Accelerating from 60 mph in Tiptronic: The torque converter remains locked, allowing for consistent turbo boost buildup and smoother acceleration.
-
Sport Mode at 60 mph: The engine operates at a high RPM (around 3000), suggesting the transmission might be in a lower gear (possibly 4th) rather than 5th, impacting fuel efficiency and potentially limiting top speed.
Further Modifications and Considerations
The ability to hold the engine at 5500 RPM in Tiptronic mode with coding “0000032” opens possibilities for further customization. Some enthusiasts are exploring using an RPM-triggered shift light controller to automate upshifts at a specific RPM (e.g., 5200 or 5400 RPM) when in Tiptronic mode. This could optimize shifting for performance driving without manual intervention.
Modifying the shifter gate to allow direct transitions between Sport and Tiptronic modes is another area of interest. This would enable drivers to quickly switch between spirited city driving with fast lockups in Sport mode and efficient highway cruising in Tiptronic’s 5th gear. However, information on how to remove and modify the Tiptronic shifter mechanism is currently being sought. Remember that modifying your vehicle’s software and hardware can void warranties and should be approached with caution and proper research. Always consult reputable sources and professionals before undertaking such modifications. Results may vary depending on your specific vehicle model and year.
