KT Lcd's are quite easy to adjust, one depresses +/- pads for approx. 5-10 secs to enter basic parameters , one can change units metric or imp, speed, wheel size etc,etc . When scrolled to the end depress the on/off quickly to enter P settings and then when scrolled to the end depress again to enter C settings. One only gets 5 secs for each change so you can't dawdle otherwise one has to go back to the very first stage and start again.
P1 is motor speed syncing with the motor winding magnets & internal gear ratio.
Get the value badly wrong and one won't hit the correct registered travelling speed.
Getting the correct value is fairly easy even if one doesn't know how many magnets or the ratio.
P2 is internal or wheel speed magnet signals, 1 or 6 are the two main values.
P3 is simply drive mode speed or current control.
P4 is throttle set up.
P5 is the battery meter display in the lcd and how the lag/sag registers.
C1 isfor selecting the correct value for the sensor/magnet disc type used.
This one is most often set incorrectly and stops the PAS working.
C2 is phase selection default is usually 0.
C3 PAS selection, the number selected is the PAS level the bike will default to when switched on. 0- 5 is self explanetary, 8 is auto and will default to the last level used.
C4 is throttle actuation and speed based on how P4 is set up.
C5 is current level adjustment .
C6 is display back light brightness.
C7 is cruise function.
C8 is motor temp ( no temp sensor is installed), as there is no wiring .
C9 is password setting.
C10 is a restore function to default.
C11 is display comms and 0 is default unless lcd 1 or 2 are used.
C12 is controller LVC.
C13 is ABS regen .
C14 is PAS signal strength.
C15 is Walk Assist spd setting.
Some displays have L settings.
L1 is controller LVC as in C12.
L2 is P1 related if the P1 setting is beyond 255.
L3 is Hall sensor related and can default to motor Hall failure if selected.
L4 is display shut down time.
