How It Works — Remote Tune

No shop visit. We flash your A8 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.

    2017 Audi A8L

    Posted by Salim Altallaa on Dec 17th 2024

    I put rs7 turbos and downpipes on. I got it tuned and it was a quick and easy process. The tune is great I had it flashed first with intense crackles then I got a reflash/retune to light burbles. Both tunes are excellent. No problems at all and Ive put over 10,000 miles on my car. The tune is smooth and it adds a lot of power. I also got the tcu tune which just made everything better. It drives like a factory car with almost 800hp. Its the best tune I've seen around. My friends have gone with other companies but they have problems and I don't even when my car has more miles. Customer service is on point.

    Stage 2 tune

    This tune is the best bang for your buck! Turned my A8L into a legitimate BEAST! But when you're driving normally it's not like most tunes where you get the weird performance in normal conditions. Hands down love this tune!
