In our continuous drive to develop BMW engine tuning tools and to help introduce ourselves to the OBD2 market, we developed ByteLogger. This tool will allow you to perform live data logging while driving on the road or on a dyno. In addition, it will provide engine diagnostics with the same precision found only in dealership software.

Read/Clear Errors
Reading DTCs has never been easier. Get a list of all errors in a matter of seconds with only the click of a button. Likewise, erasing the codes from memory is just as easy.

Shadow Codes
In addition to the primary DTCs that will cause your check engine light to illuminate, ByteLogger will alert you of any shadow codes which would otherwise be hidden. Typically, these shadow codes are visible only to dealers using specialized diagnostic software.

Freeze Frame Data
Unlike generic diagnostic scanners, ByteLogger also displays the freeze frame data from exactly when the error code was triggered. This information can help diagnose persistent problems with your vehicle.

Data Logging
The core functionality of ByteLogger is to record live engine data such as engine speed, temperature, air flow, fuel, ignition advance, and much more! All data is displayed to a scrolling graph in real-time. Afterwards, the data can be saved to a file for later use. ByteLogger is an essential tool in every BMW engine tuner’s toolbox.


USB OBD2 Cable

Additional purchase required
ByteLogger is compatible with most USB OBD2 cables which support K-Line communication and BMW diagnostic protocols. It has been specifically developed to support the infamous K+DCAN interface which is popular amongst BMW enthusiasts today. If in doubt, we offer compatible cables with our software which can be purchased during checkout by choosing the appropriate option above.


USB Analog DAQ

Additional purchase required
In addition to the many OBD2 channels that can be recorded, up to 4 differential analog signals of your choice can also be logged in parallel! Monitoring your wideband air/fuel ratio, boost gauge or practically any factory or aftermarket sensor is now a reality.

We proudly support DATAQ Instruments DI-1100 analog data acquisition module which can be purchased separately on their website. We’ve thoroughly tested this unit and it meets our needs for signal quality, cost and robustness.


Additional Notes

Please note that our software is locked to a single computer and a single VIN using a Product Key which is included in the purchase price. Additional keys to install the software on other computers or to unlock the datalogging for additional VINs will cost $25 each. This is only applicable to the original customer and is not transferable.
