Do replacement controller boards exist for the Halo Rover?

[Steamdonkey]

I have a Hyper GOGO which appears to be a very close cousin of the EpikGo and the Halo Rover.  It works OK but feels a bit sluggish for an 800W hoverboard because the reseller shipped it in beginner mode in response to a customer complaining about their kid getting hurt. It also sounds the warning alarm continuously at 7.0 mph, which is short of the advertised 9.3 mph top speed.  I can't for the life of me find any info on the web for how to restore the settings to normal / full capability mode so my only hope is to replace the controllers with something that lets the user select operating modes or make basic adjustments.  The Halo Rover appears to offer this but I can't find replacement controllers for sale anywhere.
