Yadea M6, E8s pro controller customisation

[tigerfir25]

Hi all,
I want to know if there is anyway to customise Yadea Ebikes speed? Can I increase or decrease speed at specific speed level?
For example on my M6 speed1 is 30km/h, speed 2 is 40km/h and speed3 is 50km/h. So can I reduce it further to make it locked at 25,35,45 for example?

I am also interested to know about this. I have booked a local Yadea T9 rebrand. Awaiting availability.
It is 72V 38Ah, 1200W(nominal), 1500W(peak).
Battery: Graphene based SLA/VRLA

My father have a Yadea T9 too, with 2.6kw motor, graphen akku, 50km/h max, i bought VOTOL EM 50-4 controller and installed it to the motor, and downloaded the software. But i dont know soooo many parameters that the software needs.

I wonder if is there any methodes to read the factory motor controllers parameters?
I separate the factory motor controller, saw that there is a RX and TX pin (factory cable not connected to these pins) so I connect 1 wire to the RX 1 to the TX and 1 to the GND at the left connector.
But the VOTOL EV 3 software not reading the motor controller.

Can anyone help me how to read the factory motor controller? Which software?
