Hey folks!
Do anyone knows if its possiple just to replace the controller of the ES200 (in my case the SXT MAX) with an generic one as you can find with the link or see in the picture? My plan is to modify the max-speed of my scooter (currently max-speed 20km/h).
I would be really fantastic if anyone could help me To view images REGISTER or LOGIN for full access.

Here's the code. You'll need to install fastcrc library to arduino ide. Link : https://github.com/FrankBoesing/FastCRC ... master.zip
Code: Select all
#include <Arduino.h>
#include <FastCRC.h>

int buttonPin = 2;

int lastButtonState = 1;

int counter = 0;
bool change;

bool Turbo = 1; //1 for on, 0 for off
bool seconddigit = 1; //Still unknown function
bool fastAcceleration = 1; //1 for on, 0 for off
bool KPH = 1; //1 for KPH, 0 for MPH
bool fifthdigit = 0; //Still unknown function
bool Light = 1; //1 for on, 0 for off

What type of scooter is this?

Is it any good? And any way to convert it? https:[…]
