How It Works — Remote Flash or PnP ECU

Two ways to get tuned: a live BDT remote flash, or an immobilizer-off plug-and-play ECU swap.

1

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

2

Set Up — Windows laptop with TeamViewer, our 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. Fault codes right after flashing are normal and clear after a short drive cycle.

N80 / N249 removal available for off-road use. PnP immobilizer-off ECU option always starts. This ECU family flashes via a live BDT remote session. Self-flashing with the BDT Flasher lands when this platform is ported.
