Gauge.S Classic — E39/E46 vent mount (M3 / M5)

Gauge.S Classic for BMW E39 and E46 sits in the centre vent, including E46 M3 and E39 M5. MQS plug-and-play adapter is in the box. This is the OLED unit with the vent mount. E39 and E46 share this listing.

It reads the engine over K-line or CAN, logs to an SD card you can open over WiFi, takes extra analog sensors, and includes 2× N-channel MOSFET PWM drivers for outputs. Same electronics as Classic standalone. On 2000+ cars you can use the cruise-control buttons on the wheel (cruise off).
