R2.0 TCU Update With Rolling KLi-MAX & 2nd Gear Launch How-To Guide | B9 Audi S4, S5, SQ5!
034Motorsport takes pride in listening to our customer feedback. We engaged in one of our largest customer feedback programs to date to gather extensive first-hand feedback on the qualitative drivability improvements we’ve made to suit the desires of our customers. We worked tirelessly with our testers on multiple revisions to fine-tune the characteristics of our TCU files to what our customers have found as the best driving and performing TCU file options to date.
Through the implementation of this testing and calibrating further refinements and features to our TCU files, 034Motorsport is proud to offer this comprehensive update. This update also brings new and exciting features to the AL552 transmission—Rolling KLi-MAX, Second Gear Launch Control, and No Auto Upshift—optimized for maximum performance without compromising safety.
The Stage 2 & 3 R2.0 TCU Tune Update is also now available for flashing with new and exciting features! Simply log into your 034Motorsport flashing portal, select the latest revision, and flash!
All New Features:
Stage 2 & 3 TCU - Rolling KLi-MAX
By flashing the "+ Rolling KLi-MAX" TCU file, you are enabling Rolling KLi-MAX! KLi-MAX shifting is the activation of 034Motorsport optimized AMAX gear shifts, something that is already used as a shift strategy during the use of launch control, allowing for the quickest and fastest shifts. KLi-MAX shifts minimize the torque reduction that takes place during a gear shift while increasing necessary clutch and line pressures to safely transfer more torque throughout the gear shift.
With the addition of Rolling KLi-MAX, this shifting strategy can now be engaged at any time, not just when using launch control! This shift strategy is now added to additional transmission modes (Sport & Manual) and will activate at wide-open throttle over 5,500 RPMUsers will audibly notice the lack of "farts" while on this file at wide-open-throttle. This strategy reduces the potential for transmission slip and allows for the fastest shifts possible, and is best used when looking to maximize straight-line acceleration from a roll.
See our How-To video for helpful tips and instructions on how to activate and operate this file.
NOTE: We do not recommend toggling Rolling KLi-MAX during significant prolonged wide-open throttle driving, like during an HDPE Track Session.
Stage 2 & 3 TCU - No Auto Upshift
By flashing the "+No Auto Upshift" file available in your flashing portal, your vehicle will not automatically upshift in manual mode. Your vehicle instead will hold at the engine redline until you shift your car. This feature is especially helpful when driving during HDPE or Autocross events where you want to ensure the car stays in the exact gear you want. This is a feature that is standard with the factory RS5, which we now offer to you with your S4, S5, or SQ5!
NOTE: Stage 1 & 2 ECU Customers must be updated to the latest ECU variant (R3.1 or Later) to run this TCU file variant. We recommend all customers ensure they are flashed to the latest available version of their ECU tune visible on their flashing portal. If your current ECU variant matches the current available file, then you are up to date and ready to go!
Stage 3 TCU Only - Second Gear Launch
By flashing the "+2nd Gear Launch" file available to Stage 3 TCU customers in their flashing portal, your will be able to toggle between launching in 1st gear or 2nd gear while in the car. 034Motorsport engineers have implemented the option of 2nd Gear Launch for Stage 3 customers as a way to help manage wheelspin in lower traction surfaces. In times or locations where you experience excessive wheel spin while launching in 1st gear, you can select to launch in 2nd gear to better apply the significant torque of Stage 3.
