📖 What Does It Do?

Current sensor 1 gain. MUST be calibrated for accurate current measurement.

🎯 Recommended Values

Default value: 4.7

Valid range: -100 to 100

Tuning Strategy

Start with the default value and adjust in small increments. Monitor vehicle behavior after each change before making further adjustments.

💡 Tuning Tips

⚠️ **CALIBRATION REQUIRED!** Use the 'get il1' command while running at known current.

Adjust until reading matches actual current. Typically 3-7 for standard sensors.
