Unfortunately the basic PAS system is not perfect and it does tend to pulse a bit.
You may be able to improve the pulsing by lowering the "
Acceleration" setting so that the pulses of power are hopefully reduced.
You can also experiment with also reducing the "
PAS Ratio ( 0.1 times )" setting, as the 100 setting I suggested may be a bit high for normal use, it was basically intended to check that the sensor was actually working.

Unfortunately, it will take some trial and error to find the settings that work best for your particular use.
The best pedelec experience requires a dedicated torque sensor on the bottom bracket in conjunction with a Cycle Analyst unit, but it is a lot more expensive than the simple pedal speed measuring sensor that GM normally supply with their kits.
