TuneZilla VW Mk8 GTI, Golf R DSG Bootloader

After extensive testing TuneZilla is proud to release our solution for DSG equipped MK8 R and GTI models with the "locked" 401 Bootloader. This is a physical hardware change. By removing the mechatronic unit and swapping to the TuneZilla pre-flashed bootloader, users can enjoy more features not available from the factory.

The TuneZilla Bootloader comes preloaded with the following features and adjustments:

• Torque Limiters Set 800nm
• Two Step Launch Control 3500rpm No Kickdown / 4000rpm With Kickdown
• Faster Launch Control Take-Off Reaction
• Displaying Gear Number In D/S Mode
• Sailing Mode Off In Economic Mode
• Upshift Off In Manual Mode
• Modified Clutch Thermal Management
• Optimized Clutch Cooling
• Increased Max Shift Points In D/S Mode (Around 200rpm)
• Max Clutch Pressure Values Up To 18-19bar
• Reduced Up/Down Shift Times

The new DSG tune comes pre-flashed onto the bootloader.
