We are a group of friends and we all recently purchased 50cc chinese scooters.
We would love to get a bit more power out of our scooters, since the ecu has limited them to 25 km/h.
We already contacted the manufacturer in china but we got no reply...
All that we know is that in the scooter is a:
> Rongmao ECU
> OBD2 connector
Does anyone know how we could for example let our scooters run 50 km/h?
Is OBD2 a universal standard? Is it as easy as purchasing an KESS to remap the ECU?
We basically have no clue where to start...
