bFlash is truly an all-in-one tool and comes packed with a complete set of exclusive software features required for professional ECU reprogramming.

An all new tool combines multiple functions in one platform. bFlash is not only a flash tool but also has several other functions which makes this a very powerful and unique device.

Thanks to intelligent hardware design which utilises a 3 core 160 Mhz processor, bFlash is future proof and ready to work in OBD CAN / K-line, BDM, BOOT, DoIP Ethernet, FLEXRAY, JTAG and many more protocols!


bFlash – ECU Reprogramming


bFlash is a highly advanced and extremely reliable ECU programming tool.

It can read and write a variety of different ECU types in OBD, BENCH, BOOT, BDM and JTAG.

bDiag – Car Diagnostics


bDiag supports reading and clearing of DTCs, not only in generic OBD2 mode but also most brands are covered using native manufacturer specific codes with descriptions.


bLog – Datalogging


bLog is an ultra fast data logger allowing access to manufacturer specific real time parameters. Logging parameters can be customised by the user, or simply use the preset options which include the most commonly used values.

bManager will automatically convert the raw data log in easy-to-use 2D graphs that will help you analyse the values quickly or share them with others. The integrated analytics tool allows you to customise views, axis, scaling and parameters enabling the user to examine data logs in more detail.

bSpy – Vehicle network analysis


bDiag is a vehicle network spy tool, allowing you to trace virtually any bus communication in the car. It can be used for troubleshooting, diagnostics and repair but a more practical example of it’s use would be the capability to trace and save the communication and files that the OEM diagnostic tool is sending to the car during a software update at the dealership


bTrace – ECU live emulation


bTrace or live ECU emulation (by OBD) is one of the numerous innovations that bFlash has to offer.

Over 2 years of development time was required to implement this feature, and although it will most likely only be used by a few pro tuners who develop tuning from scratch, we guarantee you that this feature will cut your development time in half. Anyone who has worked with EVC’s OLS300 emulator on EDC15 or ME7 has been dreaming of a similar solution for Tricore ECUs and it’s finally available!

Thanks to EVC, who provided a direct link between the bFlash and their WinOLS software, you can use the bTrace directly from your WinOLS.
