throttle responce

Hi,

hope someone can help.

im setting up a vesk 60100hp on a bosch gen4 mid motor (No sensors. driuver board removed)

The motor detection works fine , as does the throttle detection (chinese ebike hall sensor type)

the throttle is mapping at 2..5v max input.

however the motor starts at approx 15% and is full speed at 20% .

its practically an on off switch, although tere is a ramp if your really carefull rolling on.

this is the second vesk ive tried and both reacted the same.

Any Ideas?

regards

Tony
