Throttle
How to Tune throtmin on ZombieVerter VCU
Maximum regen on throttle lift-off (one-pedal feel). -100% = strong regen. 0% = coasting.
📖 What Does It Do?
Maximum regen on throttle lift-off (one-pedal feel). -100% = strong regen. 0% = coasting.
🎯 Recommended Values
Default value: -100
Valid range: -100 to 0
Tuning Strategy
Start with the default value and adjust in small increments. Monitor vehicle behavior after each change before making further adjustments.
💡 Tuning Tips
START at -30 or -50 and adjust to preference.
throtmin must be MORE NEGATIVE than regenmax for regen to work.
Example: regenmax=-30 → throtmin should be -50 or -100.
Think: throtmin = pedal stop, regenmax = volume at that stop.
