Yea! I finally reached the end of this thread. Only taken a month or two.
I have an E30 BMW powered by a couple of L91 motors and I also have a LogiSystems controller. That blew up. So I decided to build the Cougar and bought a couple of boards from Paul. While waiting for the rest of the parts to arrive, I repaired the LS lump (24 new IGBTs, 31 new caps, a whole bunch of comparators and op-amps!) but it still suffers from the jerky starts for which it is infamous. But now I have my Cougar controller nearly complete and am hoping for much better things! Look out World.
Anyone want a LS controller going cheap?
