If you set “rate of decline” to 0, it cannot decelerate. It will just hang at the highest speed you went to because deceleration is 0.
-Thank you so much that is a very clear explanation !-
I cant find your motor but if you are not sure you have 24 pole pairs, you can use a simple method here:

-The motors is 24 pair -60angle thats the information i got from qs motor-
Pole pairs are used to tell the controller the real RPM of the motor. It then uses that RPM for the display page as well as several others settings. If this is wrong, your adjustments will be wrong and it could be unstable.
110A on 72v system is 8000 watts. You must have a very powerful battery to handle that. If that is artificially too high then you will sag to soft undervoltage very fast and the controller will be modulating based on starvation. And your motor can only handle 8000w for limited time.
-Well the battery i have is 72v 54ah and 150a continuous discharge ( i'm aware about talking on continuous and max discharge as i'm making battery for my self) , still thanks for telling me.-
The only thing that seems like it will cause a throttle problem is your Three-Speed settings. On my controller the first box is RPM and the second box is max power used to reach that RPM.
Set at zero it wont work good. I would put 25% there in Low instead of Zero, and that will allow 2000W to be used to get you to 55% speed (Motor RPM). This is why your bus bar current needs to be set right first, because the power is based on that.
-Well i did that because i read 2 different versions of what these 3 left and 3 box right are for so i tried that, so if i want the controller to send 50% of the power i should write 50% on the right box of 55% ?
Sorry to ask i just wanna want to clearly understand the use of the 3 left/right box because it's weird the version i have read.-
Mid looks fine at 50% because thats 4000 Watts which is more than enough.
You can play with high. Sometimes it needs to be 100% to get max bus bar current. Sometimes it needs to be 0-20%, representing what percentages over bus bar current it will allow to get you up to max speed, since you need more power to get up to speed than steady state cruise at that speed.
So. I would suggest:
55% 25%
75% 50%
100% 100% (and if this doesn’t work try 20%)
If that solves your throttle problem, from there you can tune the speed and power of each gear.
I have my 3 speed switch set for low and high. Some people connect the high to sport port, so it will behave differently.
You already have soft start off so that gives the best response for a direct drive hub motor. Soft start on mine seems to put a rubber band in the acceleration.
Max torque is going to come from max phase current. Changing your three-speed second box to higher value will make more current available. Just don’t overdo it because your motor can handle 2000W, and 3000-4000 watts if moving along at 40 MPH to cool it, but it is not going to like a 5 mph climb at 8000 watts for 10 minutes.
I see , well i usually use the max speed only for less than 2 minute, usually its more the high torque i'm using.
