Does anyone have experience with MAUI e-bikes? or specifically with K5351 TFT Display/Controller?

[JakeV]

Hi I just bought a new MAUI e-bike and I was wondering if any one has experience with the K5351 TFT controller?

Unfortunately setting instructions for "PAS level select setting" and "PAS ratio setting" cannot be set while the unit is in "torque mode".

Bummer, no where does it say how to get out of "torque mode" or if any other mode exists. So i'm stuck with no PAS.

Any information on this would be greatly appreciated.

Maybe try 6.2 "Personalized Parameter Settings" first to see if you can switch it back?

Thanks for your reply it is much appreciated.

Unfortunately this setting does not say a lot and I beleive I will need to experiment a little on my own.

Of what I understand you probably either use Torque setting or PAS setting but not both.

Torque setting is used to mimick a normal bike use and from strengh(torque) it senses, it kicks in the motor.

PAS on the other hand is more like what we are accustomed to where you have 5 or 6 levels.

Let you know what I find out but thanks again for the reply

So here is the lastest on the K5351 TFT controller/display

For one, there is no word "Proporation" in the english language. This appears to be some kind of bad translation error, a contraction betwen Proration and Proportion.

From my readings, the K5351 TFT controller/display is designed to support both modes of PAS i.e. Torque and Candence if it is available for the actual e-bike.
Of course the sensors Torque and Cadence need to be present also. In my case, there does not seem to be any Cadence sensor so I'm gessing there is only Torque sensor.

The Proporation(Proration) setting appears to be a percentage and it was set originally at 24%. I Tries 32% with very little difference but at 50% started to feel very good torque from the motor.

FWIW,.. Most people that have a Torque Sensor prefer it over PAS.

The Proporation(Proration) setting appears to be a percentage and it was set originally at 24%. I Tries 32% with very little difference but at 50% started to feel very good torque from the motor.

That's the setting that I like to adjust.
It's called "throttle gears" the way I use it.

I chose 9 throttle gears with first gear turned down to ~4%, so it's for going Stupid Slow.

Then I ramp it up gradually to 100% for 9th throttle gear.


My KT controller and display have "Imitation Torque Control" which is the same sorta thing.

Power based control instead of Speed based control.

I have yet to fully understand the Chinglish translation of this KT Display setting, but it's the same sorta setting that you're adjusting,..

Don't forget that if your value is 50%, the percentage values of other gears divide automatically in equal.

Yeah, this is what I was asking myself. I will give it a try, maybe tomorrow.

We are having pretty nasty weather, freezing rain and high winds today and possibly tomorrow.

I did notice though that 50% in the snow was a very good ratio.

Thanks for the tip and the info, much appreciated.

You might be able to add gears, like what I did, where you can pick the power for a few or more gears.

You should have something similar to "PAS modes" to use.

 

[JakeV]

Yes, I have settings for "PAS Levels".

I currently have a 0-5 and I can also set it to 0-9 amongst others.

So I guess it is all about setting the PAS Level at the highest to have most granularity on the display and Proration setting at the maximum 100%.

Thanks again

Keep in mind that you don't want to be slamming your power on too hard or you'll stress your nylon gears in your motor.
Try to ramp up the power smoothly to avoid shock.

You can hear a motor stressing and I occasionally get a loud "Clunk" when my throttle timing is off.

I'm just kinda guessing because I don't pedal, and only use my throttle, but you could probably roll through your PAS levels to increase/decrease your power as you need it?

0-9 PAS with ~5 set up for snow, so 50%

I found that the power/speed isn't linear so I start out with just a few % power in PAS 1, then kinda double the power for each increase in PAS level.

You could probably get used to thumbing through the PAS modes as your pedaling and needing more/less power.
(Assuming of course that's how your ebike operates.)
