....if you do some research you will find several companies that offer/make stand-alone quickshifter set-ups. They are usually a little superior in overall operation over a Dynojet set-up, but they are a bit pricey.
It's fairly rare to see someone who would want the benefit of a QS but not also want the benefits of powercommander as well.
That one looks like it only kills the spark. Djqs kills the fuel on my set up. I guess right way to use fuel and spark.. on my bike with dj killing the fuel to me better than killing the spark, I would not want to load the engine with fuel hast killing the spark myself.
