OVERVIEW:

ECU Tuning Group’s (ETG) proprietary software for the Audi 4.0 liter TFSI® V8 engine maximizes vehicle performance, without compromising safety, reliability, or comfort.

ECU tuning refers to rewriting or remapping the software in your vehicle’s Electronic Control Unit (ECU) — sometimes referred to as an Electronic or Engine Control Module (ECM) — to improve the vehicle’s performance and/or responsiveness. The manufacturer generally uses conservative maps in the ECU to allow for slight variations across motors, poor fuel quality, and inadequate maintenance or neglect by owners.

ETG’s software is designed to safely increase horsepower and torque across the powerband, and improve the overall responsiveness of the vehicle, while maintaining the built-in safety features (e.g., knock control). With a significant increase in performance, customers expect fuel economy to worsen. But the reality is, depending on your driving style, fuel economy can improve by 10-15%, particularly when cruising at highway speeds.

In stock form, the high-revving Audi 4.0 liter TFSI® V8 with double overhead cams and FSI technology, paired to an 8-speed shiftable automatic and all wheel drive, the S8 is already impressive. By uploading new software to the MED 17 Engine Control Unit, or ECU, we make adjustments to engine parameters, such as increasing boost, ignition timing, cam timing, fuel injection, and more to increase the output of the vehicle’s 4.0 liter TFSI® V8 engine.

On most vehicles, ETG also adjusts the electronic throttle control (drive-by-wire) maps for better pedal response, transmission maps for quicker shifts, raise the rev limiter, and remove the speed governor.

With some of ETG’s software, it is best to Bench Flash the ECU (we remove the ECU, reprogram, bring it back, and reinstall — or remove and ship the ECU to us) or add a piggyback Performance Module. With the Audi 4.0 liter TFSI® V8, we are able to re-program (also known as “Flashing”) the vehicle’s ECU directly though the OBD port. It’s fast and convenient, with no downtime!

HIGHLIGHTS:

– Increase in Horsepower and Torque
– Reprogram Throttle Maps for Improved Throttle Response
– Reprogram Transmission Maps for Quicker Shifts
– Raise Rev Limiter
– Remove Speed Governor
– Undetectable at Dealership (most vehicles)
– Vehicle Can Be Put Back to ‘Stock’ Upon Request
– 2 Complimentary Re-flashes of ECU included (if Dealer Reprograms ECU during service)

*Installation prices vary with vehicle (e.g., supercharged), product type (flash vs. module) and location. In some cases, it is best that we bench flash the ECU, so the ECU should be shipped to us via overnight delivery. Alternately, we can come to your home or office, remove the ECU, bench flash, and then return to reinstall the part.
