How It Works — Remote Tune

No shop visit. We flash your S8 over the internet while you watch it happen live on your screen.

1

Schedule — after purchase, book your remote flash session with BDT.

2

Set Up — Windows laptop with TeamViewer, our OBDII cable in the port, battery maintainer on the car, key in accessory.

3

We Flash It — BDT remotes into the laptop and runs the whole flash while you watch live.

4

Drive — key off on command, unplug, done. A few fault codes right after flashing are normal; they clear after a short drive cycle.

This ECU family flashes via a live BDT remote session. Self-flashing with the BDT Flasher lands when this platform is ported.
