100% worth the wait!
Having used the tool countless time's since having it and yet to have a issue. RS3 8p over obd was a nice touch. Be able to data log and flash with the same tool is great. Still need to remind my brain i don't have to swap obd port to data logging tool. A tool every real tuning shop needs! 5 Star.

Outstanding company.
Everything in their list works, that's the most important thing. You'll never hit an issue of a non working protocol, non working logging, besides that it's ultra fast. Updates are coming lightning fast and they work flawlessly. A must have for every professional tuning company!


Supported Control Units


OBD Protocols


Bench Protocols


Boot Protocols


Diagnostic Protocols


Datalogging Protocols

We believe a control units list can be considered as a more safe approach to correctly target the overall tuning procedure due to the fact that a lot of brands offer identical car models & versions that share different Control Unit types.

Please note that bFlash can help you select the right protocol with its auto-detection feature during identification on most control units.
