Yes, that's a Race ECM (or ECU) for the White Lightning, it really wakes the motor up.
Part of today's project:

A new front isolator for the Purple Nurple which is a bit of a project to install.
Bike up on rear wheel stand, off with the tank cover, remove tank, put a jack with a block of wood under the crankcase, undo the two isolator locating bolts, remove the center isolator bolt, lower the motor down, pop in new isolator and reassemble.
It's a bit smoother now but they're still Shake and Bake until you're doing at least 65 MPH so this is not a good city bike at all.
I also popped on later turn signals which spiffed it up a bit. That was fun...
Say, I think Harbor Freight is having a sale on New Car Smell in a can right now, buy 3 and you get the 4th one free.
