How The Audi S4 B6/B7 4.2L Ecu Tune Works:

Depending on your vehicle, you may have to remove the ECU from your vehicle, package and ship it directly to Hydra Motor Works along with a completed ECU Tuning Guide. Once the ECU arrives at our facility, our tuner will flash the unit within 24-48 hours. ECUs located in the domestic U.S. will be shipped back overnight. However, International ECU’s will be shipped back via Express-International shipping. In many cases, you may not be required to remove your vehicle’s ECU. Also, we will work with you to custom-tailor your new Hydra Motor Works tune based on your specific vehicle application.
