Our Features

bFlash offers more than any other ECU flash tool. It is packed with powerful features, such as multi-method control unit programming, data logging, diagnostics, and real-time tuning.

ECU Programming
High-speed & safe reading and writing of ECU and TCU via OBD, BENCH, and BOOT methods.
Basic SAE/OBDII datalogging, manufacturer-specific datalogging (KWP/UDS), and advanced datalogging via user-provided A2L (RMBA/CCP/XCP/Custom bFlash patch).
Vehicle Diagnostics
Reading and clearing of fault codes for various ECU and TCU. Depending on the control unit, the list of faults can be retrieved either in SAE/OBDII mode or manufacturer-specific mode (KWP/UDS).
Real Time tuning
The adjustment is carried out in real-time via the diagnostic socket, on a previously patched ECU.
Datalogging review
The built-in data analysis tool lets users evaluate control units’ measurement data in MDF (Measurement Data Format) format.
CAN BUS Recording
Record and save the communication and files that the OEM diagnostic tool is sending to the car during a software update at the dealership.
