Information Nanjing Controller LD and LQ Parameters

[nicholasAZ]

Hey guys, i want to know about LD and LQ settings parameters do in Nanjing Controller. I've tried so many combinations from both of those settings and i feel in from:

LD: if my parameters set to 500 below, i think my low speed torque feels faster but slower when high speed. And so on for 500 above, low speed torque feels jitter but high speed feels slightly more faster. But i found something unusual feel actually when uses settings on 100, when i full throttle in 256, above speed 60 km/h feels like there's little boost even i don't set any boost and my Ampere max and rated was set my maximum controller which is 70A. But what makes me confuse again, i tried combination of others settings such as PID Parameters, LowVol, LimitSpdCoeff, TurtleSpdCoeff, and etc now i set to 100 it feels like balance between low torque and high speed (i don't know why, thats why im asking for the real information about LD)

LQ: im confuse in this thing. Last time, i tried set on 900, it feels slow to get high speed above 60. And the opposite of that, i set 100 it feels faster to go 60 km/h above. Feels easy to get 75 km/h than i set on 900. But, what makes me confuse, i did try again now at 1000, surprisingly, it's faster again than my last settings on 100. Thats why, i really confuse what this settings does do actually

So yeah, i hope i got my questions quickly, so i can set again my parameters at the right numbers

I believe FarDriver has repurposed LD and LQ for things unrelated to their mathematical meanings:

3.2.3 LDVOL
200-900, default 900
Matching of idling noise in high speed section and balance between power and power saving at the highest speed

3.2.4 LQVOL
Middle throttle voltage (mV, VQH+4, middle throttle enabled, 0~4000).
Speed limit current, (0~4000, unit 1/4A)

I question whether these are up to date, but they appear to be. And I can't say I completely understand the LDVOL description either.
