Motor controller and display

[Curtech]

I've got a X056-AXD001 controller w/ a LCD-M6C display. The controller is compatible with 48V nominal bikes and the display says that it can be programmed to limit the top speed to 100k/h (60mph). I've done some reading and it seems like the top speed for a 48V bike with a 750W motor is about 32mph (flat ground). I'm currently topping out at about 23mph. There's 26 different settings accessible through this LCD-M6C display, and I'll list them below. I'm curious if anyone else has a setup like this and/or knows how to adjust the top end speed. Right now, I've mucked about with things and I get all or nothing and the P20-26 must have the value 255 or I get no throttle response.

P01 - Display backlight level
P02 - kph/mph display readout
P03 - 24/36/48/60V mode
P04 - autoshutoff time (5 minutes, etc)
P05 - PAS mode 0:3 (file mode?) or 1:5 (gear mode?) -- Not sure what this does. Pedal assist setting, but, making changes doesn't seem to do anything.
P06 - While size (16 inches, 20 inches, etc)
P07 - Number of magnets for the speed sensor (1-15)
P08 - Speed limit (10-41kph) -- Doesn't seem to do anything
P09 - Zero vs non-zero start?
P10 - Power drive?
P11 - Help sensitivity?
P12 - Help intensity?
P13 - Power magnetic still disk type?
P14 - Controller amps limit (1-22)
P15 - Controller undervoltage?
P16 - Odometer reset
P17 - Cruise control
P18 - Speed ratio (50-150%) -- I think this is a spedomoeter adjustment, like if you have oversize/undersize tires.
P19 - Zero PAS (0 or 1)?
P20 - Protocol?
P21 - Unknown
P22 - Unknown
P23 - Unknown
P24 - Unknown
P25 - Unknown
P26 - Unknown

I have found 10 winding 1000 w 48 v geared hubs top out on the flat at ~25 mph. A 12 winding 48 v geared hub topped out on the flat about 22 mph. My bike has a slightly forwards seating position. Your results may vary. The 750 w motor I bought burned out on the first trip to my summer camp, so I never tried the top speed.
Note the amps of the controller will affect top speed if too low. 10 A controllers would fault out on motors capable of 1000 watts. 25 amp controller would burn the winding on a 350 w motor if run up hills.
