72V: Kelly Throttle Settings and Faults

Throttle mapping changes how the twist feels; it does not repair a faulty signal. Check startup conditions and wiring first, then use the documented Kelly settings to understand dead zones and response.

Throttle Optimization and Fault Behavior

Default throttle uses limited range.

TPS Dead Low and TPS Dead High define how much of the throttle signal is ignored at the beginning and end of the twist.

• Lowering TPS Dead Low makes throttle engagement begin earlier.
• Raising TPS Dead High allows more of the upper throttle range to be used.
• Together, these settings increase usable throttle travel and reduce the compressed feel of the stock setup.

This changes throttle feel more than peak power.

On stock throttles, setting TPS Dead Low too low can make initial response too abrupt or inconsistent. If the bike feels overly sensitive right off idle, add some dead zone back.

TPS Forw MAP changes how response is distributed across the throttle sweep.

Typical behavior:

• Around 30 gives a more logarithmic feel, with stronger response earlier in the twist.
• Around 50 feels more linear and predictable.
• Around 70 gives a more exponential feel, with softer early response and more output later in the twist.

This is mainly a ride-feel adjustment, not a fix for hardware problems.

Throttle Fault Logic

The controller expects a valid throttle range.

Fault conditions:

• throttle active at startup -> no output
• voltage outside expected range -> fault
• inconsistent signal -> intermittent cutoff

Symptoms:

• bike powers on but does not move
• throttle cuts in and out
• delayed throttle response
