Where do u get these at? Does any one have a picture of one? How do u hook it up?

Send your ECU to POWERHOUSE . . . we will flash it and send it back in one day for $55, including shipping. Let us know your setup, and we will set up your ECU accordingly, including enabling the hardcut function for all you turbo guys.

You can simply click and turn off your gear limiters and top speed restriction, as well as the fuel softcut without a dyno tune. The soft cut begins cutting fuel to a couple cylinders. The hard cut is a little higher in the rpms and cuts the fuel to all cylinders at once. That's definately something you'de want on a boosted bike to prevent leaning it out, and there's no harm removing it from a stock bike either.

You can also turn off the pair valve, turn your fans on/off sooner and alot of other cool stuff with the ecu editor. All that can be done away from the dyno, where as you'de obviously want the bike on a dyno to write/adjust the fuel maps.
The ecu editor is awesome!:beerchug:

Turning the pair off is the same as the "marble mod", blocking the hose. The p.a.i.r valve pumps air into the exhaust to improve emissions. With slipons(or altered stockers)and mainly full exhausts, you can get a popping sound on deceleration from this air flowing through.
 
By cutting all the fuel in all the cyclinders,will this hurt the bike if u keep hitting the rev limiter? Especially on a turbo bike?

I'm not a turbo guy, but it is my understanding that cutting all the fuel at once is safer than slowly leaning it down unevenly across the cylinders, especially on a turbo bike.
I would also want to tune a turbo bike with the ecu editor because it allows you to adjust so many variables.
You will also have to get an ecu (and possibly the stator)for your bike that is 2002 to 2007 as the earlier model ecu's aren't compatible.
Something from a salvage yard, it's worth the cost. The ecu editor is already about $150 cheaper than the power commander to start with.
 
the restriction is just the rpm limiter cutting in a 200 rpm earlier in top gear
its easy to bypass or turn off.
But whatever model its still got the soft cut you want to remove, or at least be aware of and not run your boosted bike on or near the limiter .
