I am not familiar with your particular LCD you have, but for some reason I know some display will only let you go up to 40km/h.After changing From the LCD display top speed is 25MPH/40 KPH
anyone knows how to unlock this limit?
Close to 30mph, maybe, but I don't think you won't go much faster than that.I’m trying to unlock it But don’t know how. Would be nice to get to 30/40 MPH
