034 Dynamic+ ECU / TCU Tune for VW/Audi B9/B9.5 S4/S5/SQ5 & 4M.5 Q7/Q8 EA389 3.0T

True Launch Control:

From the factory, conventional launch control strategies are not activated in the ECU. 034Motorsport’s skilled Calibration team has properly engineered and implemented true launch control functionality to the EA839 and AL552 ZF8. Through OEM Calibration strategies of timing reduction, Boost Control PID optimization, and torque target management, the system is able to allow for a maximum 3,000-3,500 RPM launch targeting 22psi for up to 8 seconds, making for a strong and smooth launch! Unlike the factory ECU that tries to “push through the brakes” on a standing brake launch, the 034Motorsport Dynamic+ calibration will allow proper loading of the engine without pushing through the brakes as hard, and properly targets a specified RPM to launch at.

Thermal Management Safety Strategies:

With increased power, comes increased heat. With increased heat, comes the need for additional management. For both charge air temperature and engine coolant temperature, 034Motorsport has implemented key safety features to keep your engine running optimally and safely in virtually any condition - just like the OEM calibration. Substantial effort was spent on balancing the trade off of charge temp for power, and improving the compressor efficiency so that it doesn't generate too much charge temp.

Charge Air Temp: When the charge temp exceeds 80*C there is a reduction in power output. When the charge temp exceeds 85*C there is a more significant reduction in power output. This charge temp limitation is there to prevent knock events, which can severely damage a motor. With these safety measures in place, you can confidently drive your car, from the top of Pikes Peak to Death Valley, knowing the factory ECU has optimal performance and safety covered..

Coolant Temp/Fan Strategy: From the factory, Audi likes to run hotter water temps to reduce fluid friction losses from cooler, more viscous oil. While better for efficiency, this strategy becomes a safety issue when loads and heat are increased. 034Motorsport calibrators have rescaled the coolant temperature targets and fan control strategies to target lower coolant temperatures when in higher heat conditions, allowing the car to run within a safe heat range rescaled for the added heat that comes from tuning the engine. Once again, this means that 034Motorsport calibrators have kept your confidence in safety fully intact from the OEM configuration.

RS-Style Startup Rev Enabled:

Enjoy a nice start-up rev when turning the car on with our new RS-Style start-up program!

Start/Stop Button Memory:

The Dynamic+ Tuning options for the EA839 3.0T all retain the Start/Stop engine functionality, but allow users to set memory for the system based upon preference. If you do not want the Start/Stop system to run, turn it off via the in-cabin button and the car will store that selection even after key cycling the car. If you would like it to stay on, select it to be on via the in-cabin button. This is done in a completely OEM fashion, helping enhance the overall experience of driving your car!

Increased Power and Acceleration During Shift Event:

034Motorsport tuning safely applies more power throughout the shift event, increasing overall acceleration and performance.

Enhanced Crackles in Dynamic Mode:

034Motorsport engineers have enhanced the crackles for maximum auditory pleasure! Crackles can be toggled on or off via Drive Select. They will be on in Dynamic and off in Comfort, giving you the ability to crackle when you want, and cruise quietly when you don't. In Individual, crackles can be toggled on or off via Engine Sound. NOTE: Launch Control Only Works in True Dynamic Mode.

Exhaust Flaps Permanently open in Dynamic Mode:

From the Factory, Audi will open and close the exhaust flaps randomly, even in Dynamic mode. With 034Motorsport tuning, When set to Dynamic, the exhaust valves will now stay constantly open.

Free Revving in Neutral and Park:

The rev-limiter is now removed while in Neutral and Park. Impress friends and annoy those around you with limitless ease!

Fuel System Optimization:

While E85 provides substantial increases in power, it requires about 30% more fuel than standard pump gasoline per ignition cycle. Utilizing a variety of fuel stratified injection strategies, 034Motorsport calibrators have further optimized the factory fueling system to be able to adequately support full E85 on factory hardware for Stage 1 and Stage 2 tunes.

Accurate Boost and Torque Reporting:

As with anything in life, it is always best to be truthful. This especially applies when it comes to reporting torque outputs in the ECU to the other control modules in the car, as well as displaying accurate boost readings to the driver via the boost gauge found on the Virtual Cockpit. With 034Motorsport Dynamic+ software, the ECU is reporting accurate torque values to critical systems like the TCU to ensure that all safety systems are intact in both control units, and the added torque from tuning is properly adjusted for when driving/shifting, including all safety systems designed to protect the engine and transmission.

Volumetric Efficiencies and how to optimize for them:

Volumetric efficiency (VE) is how well a motor can move air/fuel in and out of it’s combustion chamber, the higher the efficiency, the more of the air/fuel can be converted to torque and power. Every engine has a volumetric efficiency that varies with RPM. For this reason, every internal combustion engine has torque that varies with RPM; some motors, thanks to advanced features like variable valve and camshaft timing, can create exceptionally flat torque curves across a broad range of RPM simply due to optimizing VE using these advanced control features. Despite this ability, every modern engine, especially with forced induction, will have torque values that vary across the RPM band. In the case of the 3.0T EA839, there is a dip in VE at 3000 RPM, or said a different way, VE is very efficient from 2-2500 RPM, and continues to be very efficient by 3500RPM, but drops to a slightly lower level at 3000. For reference, all of our dyno charts show a dip in TQ at 3000 RPM for this very reason. It is important to note that this isn’t a problem with the tuning, and we could have very easily smoothed out the torque curve in our charts to minimize this, but we chose to leave it for the sake of accuracy and transparency.

The normal VE drop at 3000 is substantial, and more than what our final power numbers suggest, but instead of smoothing the curve to hide this, we chose to tackle it head on using our tuning expertise and technical mastery calibrating these ECU’s. A way to combat the VE drop is to increase boost through this region, but instead of simply turning up the boost using the boost control strategy, we re-engineered the ECU’s torque request function to target a higher TQ through this region. The result is more power and torque using the ECU’s factory control strategy, which keeps all factory ECU functionality and safety features in place. Ultimately we are able to make the dip less than the natural VE by raising boost a safe amount, but boost cannot make up all the difference. What we have done is optimized in performance, safety and functionality - just as if the factory had done it.

Keen observers will note that this dip is present in other company’s advertised charts too, but grealy smoothed over and reduced visually, so buyers should be aware. This dip is in the VE of the motor, it’s normal for all engines, and there is no reason to hide it or be anything less than transparent and honest about this motor’s performance.

Stage 2 and Stage 3 Dynamic+ TCU Features:

Improved Torque Management:

As with any automatic transmission vehicle, the ECU and TCU computers work synchronously to properly apply torque to the vehicle's drivetrain in a safe and reliable manner. Within both the ECU and TCU, there are factory safety tables that limit overall torque output based upon what the factory first tuned the car for. The ECU reports the output of torque from the engine to the TCU, and the TCU decides if this is suitable, or too much. If it is too much, the TCU will command the ECU to reduce torque output based upon its safety tables.

034Motorsport takes a holistic approach with its Dynamic+ Tuning, and aims to retain as many OEM safety protocols as possible. While it is possible to tune around the factory TCU torque limiters from the ECU side, this is done at the expense of torque safety features that are integral in keeping your transmission running safely. 034Motorsport’s calibrators tune the ECU to work with the TCU to provide accurate torque values, and recalibrate the appropriate safety ranges for the TCU. Taking these extra steps to retain OEM safety systems on the ECU and TCU side is just one of the many reasons that Dynamic+ software provides substantial yet reliable performance increases

Optimized Shift Points:

In order to take advantage of the increased powerband from the turbocharger, Dynamic+ Tuning optimizes the shift points in Sport Mode to maximize acceleration while retaining smooth drivability.

Kickdown Switch Disabled in Manual Mode:

When in Manual mode, you no longer need to worry about accidentally pushing through the kickdown switch on the throttle pedal!

Improved Shift Speeds:

To further enhance the acceleration of your Audi, the ZF8 shift times are dramatically decreased in all driving modes, which ultimately results in quicker acceleration.

Shift pressures are also increased in Sport Mode to maximize performance. In Sport Mode, you will notice less lazy shifts, more firm shifts, which ultimately results in quicker acceleration.

AMAX Shifting:

AMAX Shifting is a shifting strategy that stands for “Acceleration Maximum.” These gear shifts are the fastest and quickest possible for optimal acceleration . These are activated in shifting after launching your vehicle from a stop using launch control.

AMAX shift points are now optimized for specific RPM setpoints for Pump Gas ECU tunes, and Race Gas/Ethanol ECU tunes. Select the specific TCU file to match your current octane when flashing your TCU! The Stage 3 TCU tune is maximized for pump gas and ethanol files.

The S4/S5 has AMAX now activated in the 4-5 and 5-6 shifts where it was previously disabled from the factory. The SQ5 now has AMAX activated in all shifts from 1st through 6th where it was previously disabled from the factory.
