TCU Tune

This upgrade aims to enhance performance by providing faster shifting, which reduces power loss and increases overall efficiency. Drivers will notice a significant reduction in paddle shift time, leading to a more connected and controlled feel when shifting gears manually. The TCU tune offers extensive customization options to suit individual driving styles and preferences. You can select from various shift patterns, ranging from -1% to -15%, with specific recommendations for use with JB4 or LOZIC ECU. Additionally, shift pressure can be adjusted, though 'Pressure 4' is noted as not recommended except for race applications. Launch control torque limit can be set to 'ON - Stock' or 'Off', and a 'brake snip' option is available to automatically disengage the torque limit when braking. Further customization includes auto-upshift behavior in different driving modes (ECO, Comport, Sport, Sport TCS off), allowing for either stock patterns or custom 'B' patterns. The system also features an option for smoother downshifts from 2nd to 1st gear in sport mode. Optional HKS spark plugs and various sticker styles are also available for this tune.
