A New ECU & TCU Tune Revision is Now Available for your B9 3.0T EA839 from 034Motorsport! Simply log into your 034Motorsport flashing portal, select the latest revision, and flash!

A new revision of the 034Motorsport B9 3.0T ECU & AL552 TCU tune has been added to the server and is available to flash via your flashing portal! The 034Motorsport Calibration Team has been hard at work, further advancing the software and calibration strategies we have honed throughout the development process of our world-class EA839 tuning suite.

OEM Software Update:

Audi has made available software updates for select ECU Box Codes of the B9 Generation (2018 - 2020). These files are now available to select individuals. All users should select their ECU under “Flashing” while utilizing 034SPI or PC flashing client to see if there is an available OEM update. If you see an option labeled "OEM Update," we ask that you flash this OEM update. After flashing the OEM update, return to the ECU folder and proceed to flash your vehicle to the appropriate octane & specification that you would normally run.

R3.1 ECU Revision Update for Stage 1/1+ & Stage 2/2+ Vehicles:

For all Stage 1, 1+, 2, and 2+ customers, the R3.1 ECU Tune Update is available for flashing. This update should be flashed after the OEM software update, if that option is available to you. The R3.1 ECU Tune Update implements bug fixes and adjustments necessary to accommodate the No Auto Upshift feature. Simply log into your 034Motorsport flashing portal, select the R3.1 Revision, and flash!

R2.0 TCU Tune Update Featuring KLi-MAX

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!

Note: This TCU Update is only for 2018 - 2020 B9 TCU Box Codes. The R2.0 TCU Tune Update for B9.5 (2021-2022) is currently in development and will be released at a later date.

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. 

See our How- To video for helpful tips and instructions on how to activate and operate this file. 

Note: We do not recommend using this file when grip conditions are high or optimal. In our testing, we have found that the fastest accelerating launch method when grip is ideal is to launch in 1st gear.

Why Are There New Revisions?

We at 034Motorsport strive to provide the most up to date and optimized files available for your car and continually look for opportunities to improve on what we produce. As technology advances or a platform develops, we refine and Improve files as needed. In some cases, these are very minor adjustments, whereas, in others, these updates can bring a whole round of feature additions and performance changes. More info can be found below on how to identify a large change vs a minor/unnoticeable change based on the revision number.

Revision Nomenclature Breakdown

Revisions will be listed under 3 main categories, as shown in the numbering of the revision. 

Example: R7.1.5

The first digit signifies a Major Revision/version change/count. In this example, 7 would be the most recent of major revisions. These numbers change when a major feature has been added or updated (such as Advanced Launch Control or higher power output files). 

The second digit signifies a minor revision/version change/count or changes to files that are not considered major but are noticeable in the overall performance and refinement of the car. In this example, the 1 in R7.1.5 would mean that a minor change was added over the base R7 file. 

The third digit signifies a sub-revision/version change/count or changes that are very minor/unnoticeable. These adjustments are generally box-code specific adjustments or bug fixes that change parameters of the tuning that most will never notice in their day to day driving but refines the overall file by solving minor bugs. In this example, the 5 in R7.1.5 would be the 5th minor sub-revision to this file on this box code. 

Note: Not every box code needs the same sub-revision changes. Often they are box code specific and not necessary for every box code. If there is no sub-revision number listed for your file on your portal, then there is no need for an update in that category of the patch.
