I wish I could write it now, but at this time I am still working though what each setting does.
To start, here is my interpretation of the factory guide. This is not set in stone, so feel free to correct any mis-interpreation I may make.
The user manual is here, the download link, first download:

Here, they seem to use the word "gears" to mean power assist levels.
"Zero start"=instant start(throttle).
"handlebar"refers to the throttle.
"foot power assist" is the PAS.
This is clear enough. My Q100C has 16 magnets and a reduction ratio of 14.2:1, so P1 = 14 X 16 = 224P1 Motor Characteristic Parameter Setting Mode
P1 is motor characteristic parameter setting mode. P1 = motor gear reduction ratio×
number of rotor magnet pieces, just rounding if there’s any decimal.
My geared motor requires an external wheel speed sensor, so the setting is 1. I assume the higher values are for DD motors where the external sensor can be deleted.P2 is wheel speed pulse signal setting mode. If wheel generated 1 pulse signal by a
revolution, P2 should be set as1. If wheel generated 6 pulse signals by a revolution, P2
should be set as 6. If users didn’t configure the pulse signal system, and then P2 parameter
setting can be 0. The setting range of P2 should be between 0-6...
I understand "imitation torque control" mode to be a euphemism for current(Amp) limiting. Whether this applies to PAS, throttle or both is unclear to me.P3 is for power assist control mode, when P3 parameter setting is 1, power assist
control mode is gear 5 of "imitation torque control" mode, when P3 parameter setting is
0, power assist control mode is gear 5 of "speed control" mode.
P3 parameter needs to be determined according to the distributed function of the controller, its setting range is 0 or 1...
"P3 parameter needs to be determined according to the distributed function of the controller, its setting range is 0 or 1"
P4 is handlebar startup mode. When P4 setting is 1, indicating the handlebar is under
"non-zero startup" mode, namely, the handlebar can be effective only after startup the
foot power assist. When P4 setting is 0, indicating the handlebar is under "zero startup"
mode, the motor can be startup by the handlebar directly. P4 setting range is 0 or 1...
1 signifies one must pedal first before the throttle becomes active.
0 means the throttle is always active.
I have not worked with this yet, but values above 0 appear to be dampen out Voltage sag as power is applied, to steady the reading. I assume the value(above 0)would be a function of battery type and Voltage. There is an additional setting in the "C"parameters. Any input of what works for your type and VoltageP5 is power monitoring mode, when P5 setting is 0, the power monitoring is the
"real-time voltage" mode. Namely, it is the method to determine the battery capacity
based on real-time battery voltage. When P5 equals to a specified parameter, the power
monitoring is the "smart power" mode (this parameter is determined by the battery
characteristics, ordinary 24V lithium is generally is 4-11, 36V lithium is between 5_15). P5
setting ranges from 0-40
pack would be appreciated.
This appears to be related to the # of magnets in the PAS rotor, My question here is; does this need to be set for PAS to function?C1 is power assist sensor and parameter select mode. Its definition is shown in
following table. C1 setting ranges between 0-7, hold button (UP) or button
(DOWN) for selection.
C1 parameter definition table：
Quantum power assist sensors or similar
Power assist sensors from other
00 5 magnet sensor 05
01 8 magnet sensor 06
02 10 magnet sensor 07
03 12 magnet sensor
I have no idea about this one.C2 is motor phase classification coding mode. It is served as identification parameter
of different phases of the motor when using sine wave drive and the default value is 0.
When C2 setting is 0, indicating that the used Quantum motor phase is an ordinary one.
When the setting is a certain value, indicating a particular motor phase is used. C2 setting
range is 0-7...
This appears to determine how P4 functions, but other than thatC3 is initialization mode of power assist ratio gear. The setting range is 0-6 (gear)... ...When C3 setting is 0, the
meter is switched on, and the power assist ratio is at gear 0. When the setting is 1, the
meter is powered on and the power assist ratio is at gear 1, and so on.
These determine how the two functions of P4 are applied.C4 is handlebar function setting mode.
C4 parameter definition table:
Handlebar startup mode P4=0
0=zero startup handlebar
1=Zero startup, handlebar speed limit is
2=Zero startup, handlebar speed limit is specified
3=Zero startup, handlebar speed limit is specified. (Power assist ratio is effective at gear 0)
Handlebar startup mode P4=1
C4 parameter definition table:
0= Non-zero startup handlebar
1= Before power assist, the handlebar speed limit is 6Km/h, after power assist, handlebar is full speed.
2= Non-zero startup, handlebar is specified speed limit.
Amps limiting function.C5 is controller maximum operating current adjustment mode (tiny-adjustment of
limit current value). The default value is 10...
C5 parameter definition table：
C5 value Maximum current value(A)
00 Maximum current value-5
01 Maximum current value-4.5
02 Maximum current value-4
03 Maximum current value-3.5
04 Maximum current value-3
05 Maximum current value-2.5
06 Maximum current value-2
07 Maximum current value-1.5
08 Maximum current value-1
09 Maximum current value-0.5
10 Maximum current value
When C5 setting is 10, maximum current value is controller maximum operating
current value (ie, limit current value); when setting is 9, maximum current value minus 0.5A, when setting is 8, maximum current value minus 1A and so on.
For SO6S controller, 00= 10A, 10= 15A, for S12S controller, 00=18A, 10=23A.
Self explanatory.C6 is the meter backlight brightness adjustment mode.
self explanatoryC7 is cruise function setting mode.

SEE POST BELOWC11 is meter attribute selection mode.
C11 parameter definition table：
C11 value Meter Attribute
0 Meter uses LCD3 new version of communication protocol, it is compatible
LCD1 and LCD2.
1 Meter uses LCD1 and LCD2 old version communication protocol, it is not
2 As data source for copying parameters, the meter transfers the new LD3
parameter to other meters.
This appears to allow fine-tuning of the LVC.C12 is controller minimum operating voltage adjustment mode (tiny adjustment of
voltage shortage). The default value is 4...
C12 parameter definition table：
36V Controller and 48V Controller
0= Default value-2V
1= Default value-1.5V
2= Default value-1V
3= Default value-0.5V
4= Default value 30V for 36 V battery, Default value 40V for 48V battery.
The controller senses battery Voltage and establishes the default setting(#4). Other available values add or subtract from default setting.
How this works with non-standard batteries, ie; Lipo 12S(approx. 44V), I have not determined yet.
Anyone that can elucidate any of these functions, especially C3 and\or C4 as they apply to P4, and C12, please add your input.
