📖 What Does It Do?

Current per percent throttle — this is your POWER control. Higher = more torque.

🎯 Recommended Values

Default value: 1

Valid range: 0 to 10

Tuning Strategy

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

💡 Tuning Tips

⚠️ **THIS IS YOUR MAIN POWER PARAMETER.**

FORMULA: throtcur = desired_max_current / 100

throtcur=1 → 100A max at 100% throttle (weak)

throtcur=4.5 → 450A max (Leaf EM57 moderate)

throtcur=5.5 → 550A max (Leaf EM57 aggressive)

throtcur=6.5 → 650A max (racy)

Start low and work up. Actual current also bounded by iacmax and idcmax. If you hit overcurrent (ocurlim) immediately, throtcur is too high for your hardware.
