From the developer:
SManager is a program for use with the s300 circuit board. SManager allows you to load, save and edit ECU calibrations, re-program your ECU, view ECU information in real time, and record & playback datalogs from your ECU.
The s300 is a circuit board which fits inside the ECU. A slot is cut in the side of the ECU for the USB connector. The ECU uses different connector pins than the s100 & s200 (male pins vs a socket).
