DL501 (DSG) TCU Tune | Audi B8/B8.5 S4, S5 | 034Motorsport

Overview

034Motorsport's Dynamic+ DSG Software Upgrade unlocks the full potential of the DL501 7-Speed S-tronic transmission found in B8/B8.5 Audi S4 and S5 models. Flashed directly through your vehicle's OBD-II port, 034Motorsport's proprietary calibrations for the DL501 TCU safely and effectively raise the factory transmission's RPM limiter, allowing your car to make full use of Stage 1/2 Performance ECU Software. Performance DSG Software also increases shift speed and optimizes the shift points in Drive and Sport modes for better performance and drivability. The result is a noticeable improvement in acceleration, without any sacrifice in comfort or reliability.

034Motorsport's DL501 Performance Software was developed entirely in-house on 034Motorsport's Development B8 Audi S4, then refined on multiple enthusiast-owned B8/B8.5 S4/S5 vehicles before release. In addition, End User Flashing allows Dynamic+ Performance Software customers to receive and install software updates and revisions, flash back to stock, or upgrade to the next stage of performance software for their vehicle.

TCU Features

Transmission Calibration

034Motorsport recalibrates the DL501 transmission to maximize the available powerband while improving overall transmission behavior. A raised transmission RPM limit allows the engine to remain in its optimal power range, while optimized shift logic and increased clutch clamping pressure improve power transfer and overall performance.

Shift Performance

Dynamic shift mapping delivers quicker gear changes and revised Drive and Sport mode shift schedules for stronger acceleration and improved responsiveness. Manual mode is also enhanced by disabling kickdown, giving the driver complete control over gear selection.

Launch Control Optimization

Performance DSG Software introduces user-selectable 4-step Launch Control, allowing drivers to choose from 3,000 RPM, 3,500 RPM, 4,500 RPM, or 5,000 RPM launch settings to better match available traction and vehicle setup. The factory Launch Control counter limit is also increased from 200 to 2,000 activations.
