Audi R8 V10 2017Custom ECU Tune
The electronic brain of your car — recalibrated.
A few decades ago, some nerds figured out that computers allowed for incredibly precise control of internal combustion engines... thus the ECU was born.
The Engine Control Module — often shortened to ECU, ECM, or DME — is the electronic brain of all modern cars. Unfortunately, car makers must consider things other than performance when designing ECU software, leaving much to be desired.
Enter S4T. Focused solely on properly developed ECU calibration software, giving you the highest performing and best driving car possible — sharper throttle, stronger mid-range, optimized airflow, and a more characterful engine note.
Switch back anytime.
Before we flash a single byte, we save your original ECU file. If you ever need to return to factory — for service, resale, or any other reason — you can revert to stock at any time.
How Remote Tuning Works (OBD)
Step 1
After you check out, you will receive a form via email (FILL OUT THE FORM). Tuning tools will be shipped.
Step 2
Ensure access to a windows 7+ laptop & Wi-fi & Mobile Hotspot Recommended for Data logging.
Step 3
Tuning & Data logging will be performed via OBD port (We walk you through it).
Step 4
Have Fun.
ECU UNLOCK “OBD”
OBD communication is awesome, tune and datalog your car easily from the drivers seat via the diagnostic port (OBD2) found under the dashboard. Tuning cable is shipped and instructions provided with purchase.
