Stihl uses different connectors for different product families:
An MS 462 C-M revs fine but bogs when cutting. No fault codes appear. The technician uses Live Data streaming and watches the "short-term fuel trim" spike to +25% when the chain touches wood. This indicates a lean condition. The software’s calibration routine resets the M-Tronic system, and the saw cuts perfectly. stihl diagnostic software 2.0
The software can read and clear fault memories. For example, it can identify pressure sensor failures in fuel-injected models like the MS 500i chainsaw. stihl diagnostic software 2.0
