What does a race ecm do for the ULY? MPG? Power? Cost? Will it do anything for the bike with the stock muffler? | ||

Not sure you can run it without an aftermarket pipe. I noticed some pretty good gains with the race ecu and race pipe. More topend thats forsure. | ||

Race ECM - Makes the Uly run the way it should have in factory trim, no pings, smooth power delivery, etc. I average approximately 50 MPG. My Uly was delivered with the Race ECM, Muffler, air filter (since changed to American Sportbike open filter kit) so I could not personally speak on the difference in power delivery. The Race ECM cannot be used with the stock muffler, to my knowledge. Good luck | ||

I think I remember someone saying they tied the exhaust valve open and ran the Race ECU. It does not actuate the valve like the stock ECU does. | ||

Chad's right. You can use the stock muffler with the valve wired open. Otherwise, you will get unwanted restriction. If you're going for the ECM, you might as well get a pipe and freer breathing filter as well. | ||

What is the cost of the ecm? I like quiet mufflers. |
