My KU123 controller blew a few weeks ago, and this is the only replacement I could get quickly:

I had a bit of bother fitting it as many of the connectors were wired up differently from the KU123, but I got there in the end.
However, with the KU123 running at 48v with my Q128 rear hub on a 26 rim I got about 30mph on the level and 30amps.
With this controller I get about 23mph and about 24 amps or so.
I'm wondering if I've wired something wrongly ? I've not got the white speed limit wire connected, and neither have I done anything with the '3 speed' wires as I'm using the basic throttle.
However is it possible with this controller I need to ground the high speed wire or pull it to 5v or something to get my full 30 amps out of this controller ?
