Audi S4 B9 tuning: flash your maps without a workshop
From the factory the Audi S4 B9 produces 354 PS and 500 Nm (all power figures on this page are metric PS), and its 3.0 (EA839) still has noticeable software headroom. With the NGM App you unlock it yourself: a fully calibrated Stage 1 file is flashed to the engine control unit straight through the OBD2 port. No workshop appointment is needed, the ECU stays in the car and no chip is swapped. All you need are the NGM App on your iOS or Android phone and the NGM OBD Adapter, a one-time purchase. Supported are S4 B9 models built from 2016 to 2019.
Before you start: driving with optimized maps is not permitted on public roads. The files are intended exclusively for use on closed race tracks. The optimization can void the vehicle's type approval and the manufacturer warranty, and you use it at your own risk.
Audi S4 B9 Stage 1 and Stage 2: figures and availability
The S4 B9 comes as exactly one engine variant, and the Stage 1 calibration is matched precisely to it:
- S4 B9 3.0, 354 PS (2016-2019): Stage 1 delivers up to 420 PS and 620 Nm, starting from 354 PS and 500 Nm stock. There is no Stage 2 for the S4 B9, so Stage 1 is the highest available stage.
Please note: all maximum power figures were measured with 102 octane fuel and represent the maximum achievable output.
The All-in-One license comes as a download and is bound by VIN to exactly one vehicle. For the S4 B9 it contains the complete Stage 1 software for the engine control unit. After the purchase the app provides the file for your car, and no further preparation is required.
Pops and bangs for the Audi S4 B9: the Sound license
If the added power still needs a matching voice: the separate Sound license activates the crackles function in your S4 B9, in other words pops and bangs. It is flashed exactly like the performance software, with the same NGM OBD Adapter and the same app. Like every license it is a download bound by VIN to your specific vehicle, and you can run it alongside the All-in-One license or completely on its own. The same rule applies to the sound functions: they are intended for closed tracks only.
Tuning the Audi S4 in four steps
You handle the whole tuning process yourself at the car, with no appointment and no wrenching. This is how it goes:
- Plug the NGM OBD Adapter into the OBD2 port of your S4.
- Open the NGM App on your iOS or Android phone and connect it to the adapter.
- The app reads the VIN and identifies your S4 B9 automatically.
- Pick your license and start the flash, and the software goes straight onto the control unit.
Vehicle data for the S4 B9 is usually available immediately. Only if the NGM App has never been used with your vehicle and the data has to be prepared first does it typically take around 5 days, 14 at most.
