Woolich Racing Log Box D v3 (Denso)

Woolich Racing - Log Box (Denso)

The Woolich Racing Log Box D (Denso) (LBD) automatically logs engine data directly from stock Denso ECUs to an on-board micro SD card every time you ride your bike. The Log Box can be permanently installed on your bike. When you are ready to tune your bike you can connect a laptop to the Log Box via a standard USB cable. The log box appears as an external USB hard disk on your laptop and you can load the logged data directly into the Woolich Racing Tuned software to AutoTune your fuel maps.

The Log Box (Denso) LBD also allows you to Read/Write (Flash) Denso ECU's and view real time Engine Data in the Woolich Racing Tuned (WRT) software.
