here is mine...

It runs off a battery, you loop the pickup wires back to the unit and remove the source coil off the stator.
You can do custom maps... if you had a carb with a TPS you could even set up a 3d map
I havent dynoed mine yet, but a mate got 5hp on his standard TS1 just through bolting this on and setting it on a dyno. It runs a separate coil and shocked a friend standing near a steel bench!
I got mine from a local agent in New Zealand, but they are made in Czech republic
