Dyno Numbers Coming Soon

We're the first to crack the 40 TFSI. Every stage is headed to the rollers right now — real before/after wheel numbers land on this page the moment the sheets are shot. No borrowed graphs. No fantasy figures.

 

How It Works — Flash From Your Phone

No shop visit. No laptop. Flash your 40 TFSI straight from your phone with the BDT flasher app and our Bluetooth OBDII dongle — then data-log and refine from the same phone.

1

Get Access — after purchase you're set up with the BDT flasher app and your calibration files.

2

Plug In — pop the BDT Bluetooth OBDII dongle into the port, pair your phone, battery healthy, key on.

3

Flash It Yourself — pick your stage in the app and flash it over Bluetooth in minutes. Switch stages or return to stock any time.

4

Data-Log From Your Phone — record live engine data right in the app and send it to BDT so we can dial your car in.

Unlimited File Updates — whenever BDT releases an updated calibration for the 40 TFSI, it lands in your app at no extra cost. You get every published file update we push to the platform — not one-off custom revisions, but every improvement we make for the whole platform, for as long as you own the car.
