Driver Motorsport, LLC has developed the best ECU Software Upgrade available Audi B8 / B8.5 A4. With peak gains as high as 95 HP & 139 TQ Driver Motorsport‘s Audi B8 / B8.5 A4 software will put your Audi’s performance in the same realm as the S-Line vehicles.
Utilizing the engine’s untapped potential and Audi Valve Lift Technology, Driver Motorsport was able to deliver huge low end torque increases that turn into smooth power increases on the top end. Ultimately giving the driver more confidence behind the wheel. Driver Motorsport managed to improve fuel economy by increasing the volumetric efficiency of the engine during light acceleration and cruising conditions.
Driver Motorsport‘s ECU Software Upgrade is developed to operate within the safety margin of all engine related components. Driver Motorsport is offering performance without fear of bad consequences from improper engine calibration. Through extensive long term testing on our in-house Audi B8.5 A4 we can state confidently the customer can achieve massive performance gains without negative trade offs.
To engineer any product properly, it takes dedication and the required allocation of development resources. This is the methodology we followed when creating the Audi B8 / B8.5 A4 software and our results justify it.
The purchase of our 2013 Audi B8.5 A4 was the beginning of our product development. Immediately, we recognized the glaring flaw with this car was is it’s serious lack of power in stock form. In comparison to the rest of the Audi line up, the Audi B8 / B8.5 A4 is deficient on horsepower and torque. Despite this, the B8.5 A4 quickly became our vehicle of choice for our daily driving duties. After a quick look at the available software offerings for this vehicle showed a very limited and weak range of options for K04 software and stock turbo software with most of the software developed years ago and left untouched. Driver Motorsport seized this opportunity.
Reliability Testing:
With any of our ECU Software Calibrations, the lengthiest part of development takes place in long term reliability testing. We had a physical exhaust gas temperature (EGT) probe installed on both the stock downpipe and the upgraded downpipe we later installed for Stage 2 Software development. We have precisely dialed in the optimal air/fuel ratio as well as re-calibrated the ‘Component Protection’ of this ECU. Component Protection is designed to allow the air/fuel ratio to richen up once EGT reaches the manufacturer’s maximum threshold. Once Component Protection is active the EGT will then settle at a safe equilibrium temperature below the manufacturer’s maximum threshold.
We have re-calibrated the protocol the ECU takes when intake air temperature (IAT) gets too hot. To avoid detonation and ensure our file is safe in the most extreme conditions, we calibrate the timing advance and load request to be dynamic to IAT.
Audi B8.5 FlexFuel Calibration (XXXX Engine Code)
Quite possibly the greatest 2.0T Engine Audi has ever built is the engine found in the FlexFuel Compatible Audi B8.5 A4 / A5. With it’s improved fueling components, this engine has the ability to be revolutionary for the entire EA888 Gen 1 & 2 Engine Family. With the proper knowledge and skill, this engine can produce serious gains without sacrificing reliability.
To handle the vary E85 content, the engine is equipped with numerous upgrades:
- Ethanol Sensor
- Larger Fuel Injectors
- Improved Low Pressure Fueling System
- An additional 5th Injector to improve cold start performance
- Aluminum Intake Manifold
- Upgraded Cylinder Walls
The ECU found in the Audi B8.5 A4 / A5 is the newest generation of Bosch’s MED17 ECU. The ECU is designed to support flex fuel and has many additions specific to allow the ECU to recognize the engine’s ethanol content and blend various maps accordingly. This ECU has more sophisticated tuning protection security and the additional content makes it more complex to develop an ECU Calibration. Driver Motorsport welcomed this challenge and is proud that we are one of very few companies in the world that can properly support the Audi B8.5 A4 ECU.
