What you may experience with your stock DSG software

As with previous generations and other variants of the DSG, ECU Performance Software and engine hardware upgrades resulted in shortcomings in the stock control logic; gear change setpoints, gear shift speeds, limitations in allowed torque through the gearbox, engine rev limitations, and much more; all stemming from the increase in engine output. In Drive-mode, drivers often experience premature upshifts as a result of the stock calibration being aligned with the factory engine output. In Sport-mode, part throttle acceleration held the gears too long, causing an awkward driving experience. In Drive-mode and/or Sport-mode, shift points are often misaligned with peak engine output, costing drivers with imperfect acceleration. And Manual-mode is not a true “manual” mode, as gear changes still occur at redline and engagement of the kickdown button still result in unwanted downshifts.

Why choosing Unitronic Performance Software for your DSG

Utilizing its extensive knowledge of the TCU from its offerings for previous generations and other variants of the direct-shift gearbox, that developed a strong reputation in the market, Unitronic’s Performance Software for the DL501 DSG will deliver a complete night and day driving experience. With two Stages, Stage 1 & 2, Unitronic’s Performance Software for the DL501 DSG is precisely re-calibrated to ensure shift points in Drive-mode and Sport-mode are aligned with increased output and powerband of a Unitronic tuned engine to ensure maximum acceleration, deliver lightning fast gear changes to gain valuable time during acceleration, and raises TCU torque limitations to ensure the TCU does not intervene during acceleration. Unitronic’s Performance Software for the DL501 DSG will allow drivers to feel more connected to the vehicle and will experience a total transformation in the driving experience.

FEATURES

Engineered with Strict Industry Standards

With over 10 years of experience with Bosch and Siemens engine management systems and calibrations, Unitronic is able to utilize its expertise, industry leading tools, and equipment to ensure an optimal calibration; delivering maximum performance, while maintaining complete OEM-like reliability and drivability.

Extensively Tested Under Various Driving Conditions

Development begins using its in-house engine dyno housed in an environmentally controlled cell; closely monitoring a plethora of operational data, utilizing industry leading calibration tools and resources. Additional validation and results comparison are completed using its in-house Maha Chassis dyno as a second step of product development. Beta calibrations are then tested in race and street scenarios, using multiple cars throughout the world under various driving conditions. This engine calibration strategy ensures Unitronic Performance Software delivers maximum performance, OEM-like drivability and reliability anywhere in the world. Unitronic Performance Software is only released to its Clients once development is thoroughly completed in accordance to Unitronic’s strict standards.

Optimized Responsiveness and Drivability

Cruising upshifts set point are improved for maximum responsiveness when you require power quickly.

Optimized “D” Mode for a Comfortable Driving Experience

Smoother and predictable shifting to ensure a pleasant ride for your daily commute.

Optimized “S” Mode for Maximum Acceleration

Sport mode features lightning quick gear changing and precisely calibrated shifting points to achieve the fastest acceleration possible when combined with your Unitronic ECU Performance Software.

Optimized “M” Mode for Maximum Acceleration and Kickdowns Removed

Fastest shift possible; up to 3 times faster compared to OEM calibration.

Optimized TCU Performance Software Stages

Unitronic’s Stage 1 TCU Performance Software shift points are optimized to give you the best performance possible out of your OEM software or your Unitronic Stage 1 ECU Performance Software.

Unitronic’s Stage 2 TCU Performance Software shifts points are optimized for your Unitronic Stage 1+ and up ECU Performance Software.

Gear Display Enabled in D and S Mode

Like in M mode, gear display is enabled in D and S mode.

Improved Launch Control

Optimized set points to maximize accelerations and improve 60ft time. Launch control set to 4000 RPM in the B8/B8.5 S4 & S5.

Increase Clutch Pressure for Higher Torque Output

Increased clutch pressure to maximized friction force. This results in higher torque capacity without clutch slipping.

Increased Torque Limiter

Ensure TCU does not intervene during acceleration thus reducing engine power output.

Rev Limiter Increased
