Try to change P3 to 0. When set to 1, the PAS level limits speed. Regardless of if the PAS is installed of not.

Here are my settings for my Shengyi 1000w geared rear hub motor.

Will your settings work with my kit?

I can't say either way. If your motor is a direct drive, then no. If it is a geared motor, then maybe yes. You can try my settings and refer back to your photo if it doesn't work. Your motor may not operate as desired, but nothing would be damaged by trying. You can always revert to the settings you have in your previous photo.

Ok I will try it.

The place where I got the kit from says you can use a 48V or a 52V battery. This is where I got it from.

I looked at the page where you bought the motor and controller, and according to the information, your motor is a DD (direct drive), where the gear ratio is 1:1. Therefore, you should change the P1 parameter and enter only the number of magnets in your motor.

How will I know how many magnets there are?

That information should be known by the seller of the motor, or if the motor has a specific name, you can search for it on the internet by its name. Perhaps someone here on a forum might also know.

Once, I had a G25 direct-drive motor from Crystalyte. In the PDF manual, it indicates that the number of poles in a pair, as they say, is 22. I interpreted this as the number of magnets being either 22 or 44, I don't remember exactly.

I don't know how crucial the P1 parameter is for your bike to function properly. Have you tried the bike to see if it works now?

Thank you. I have emailed the seller about the magnets.

Not yet I'm still at work and my battery needs charging.

It would be good if he could send you all the settings for each parameter, or, most simply, send you a picture of how it's set up from the beginning.

I asked him for that as well.

You can try 46. It wont hurt to try. That is a setting recommended on a radcity, which also is DD. A similar kit can be found at The Upgrade Kit Default Settings and Troubleshooting Tips - Area 13 Ebikes.

Since you have a direct drive motor, your P1 setting should be 51.

51 magnets, so 25.5 polepairs. That is "impossible". Polepairs is always even numbers, and divided by 2. So if you have 46 magnets, then it is 23 polepairs. 16 magnets = 8 polepairs etc.

So ask your seller again. And if seller cannot tell you right answer, then don't buy anything in that kind of sellers anymore.

My spec.say there are 46 numbers of poles so does that mean I have 46 magnets

Hey guys, I thought I would share this about the topic of "KT-LCD8H settings".

I asked the three popular AIs "I want to configure the KT-LCD8H settings for maximum power output."
so I can see what settings the AIs recommends for maximum power output (which I assume most people actually have by default, but not me).

I lately have my KT-LCD settings in mild economy mode for slower=safer=commute habits plus less battery recharging and wear/stress, but was curious what it would say in case I have missed anything for max power, and my bro is visiting so I figured I would let him ride my recent bike build and enjoy it at around max power mode.

I also asked the AIs "Can you rewrite the entire KT-LCD8H manual for all the P,C,L setting outputs so they are a bit more concise in their meanings?". All three AIs output a great concise manual for all the main KT-LCD8H settings, no guarantees to the output accuracy but it appears to be mostly correct on basic inspection.
Hope it helps. :bigthumb:
