UPDATE!!!
The manual YL81F does not seem to be correct for my Keteles K800 With Dual Motors. Example: The Manual sez PAS is P03. When I goto my settings it sez 48. Which is "VOLTAGE"
I just got these new settings and they seem to match what is on my display. I went to P03 on my display and it matched what I have below! Here they are:
P01=003 (back light level)
P02=000 (KMH or MPH)
P03=048 (voltage)
P04=010 (screen timeout 10 minutes)
P05=005 (first number = when the motor helps 0 or 1, 5 = levels)
P06=29.0 (tire size)
P07=086 (? Not sure)
P08=100 (speed limit in kmh)
P09=000 (0 motor helps immediately when you pedal)
P10=002 (0 is pedal assist only, no throttle, 1 is throttle only, 2 is both)
P11=001 (sensitivity of pedal assist 1-24, 1 is the highest)
P12=005 (intensity of power delivery 1-5, 1 is the most)
P13=005 (number of magnets on crank sensor 5,8 or 12)
P14=012 (max amp draw of controller)
P15=38.0 (under voltage cutoff, 38v vs. 48v)
P16=002 (reset ODO, hold mode button and ODO returns to 0)
P17 = 00 (cruise control)
P18 =01 (walk boost)
hope this helps!
