Replacing Lishui Controller Recommendations

[Jel]

I have a SDREAM X750S bike with a Lishui LSW1247-59-5F controller. While I've looked into many things including trying a EggRider display to remove the limiter I now feel that the only way of going above 20mph (I commute on a 25mph road) is to replace the controller. Any recommendations welcome.

Thanks J
