Depending on the control unit, our solution can provide basic SAE/OBDII datalogging, manufacturer-specific datalogging (KWP/UDS), and even advanced datalogging via user-provided A2L (RMBA/CCP/XCP/Custom bFlash patch).

Real Time Tuning

Intended for our expert users, this solution was designed to simplify your work by integrating an editor within the bFlash interface. The adjustment is carried out in real-time via the diagnostic socket, on a previously patched ECU.

Our proprietary patch, which allows both real-time editing and high-frequency data acquisition, can be applied in BOOT, BENCH, or OBD, depending on the methods supported by the control unit.

Vehicle Diagnostics

Reading and clearing of fault codes for various ECU and TCU. Depending on the control unit, the list of faults, also called DTC (for Diagnostic Trouble Code) can be retrieved either in SAE/OBDII mode or manufacturer-specific mode (KWP/UDS).

Diagnostics: Dyno mode

Dynomode is a feature that allows proper vehicle power measurement on test bench (Dynamometer). Depending on the vehicle and installed control units, features like ESP, ABS and front assist will be turned off, thus preventing these critical modules to be bypassed during measurement.

Datalogging Review

The built-in data analysis tool lets users evaluate control units’ measurement data in MDF (Measurement Data Format) format. Our intuitive time slider allows users to zoom out to short timespans. Many functions are designed to make your work easier, for example, you can overlay and compare two datasets in a matter of seconds.
