I have a 06 Uly with a Race ECM and a Buell Race exhaust. The bike runs fine but I think that it's a little flat on the low end up to about 4K and it's a pinger in hot weather. I have the stock muffler and was wondering if anyone runs the R ECM and the stock muffler with the actuator hooked up? I don't care about the top end so much looking more for the low end to pull better. | ||

IIRC the race ECM doesn't have the function built in to control the actuator. If you want that, you'll have to go back to the non-race ECM. | ||

Good point, I didn't know that. If I wired the actuator open would there be any improvement on the low end over the R muffler? Thanks, mike | ||

No, because the valve is closed during typical low end driving. You would be back at square one. | ||

What about the Drummer? It has fantastic low end. | ||

Well it was just a thought since I had it. Not really looking to spend any more money, the bike runs fine. I should look into some tuning on the ECM for the summer months. Thanks | ||

The race ecm and race muffler were designed for... racing... ie; running in the upper RPM range. You can tune the race ecm, but the muffler was not really designed for lower RPM operation. That being said, I also have a race ecm and race muffler on my Uly. One of these days I'll probably switch them for a stock ecm and a Spec Ops or a Drummer can. | ||

Highlander- I'd imagine you could find a standard ECM cheap on ebay or from a Badwebber. It might be worth trying the standard ECM/muffler combination to see if it gives you what you're looking for. | ||

You may be able to tune the ECM to be a bit happier at low Rs with ECMSpy. I found an improvement with the stock ECM running a race map, then tweaked for happiness via the normal process (laptop in backpack). Ended up with some ping around ~3.5K IIRC, and slight retard and fattening the mix pretty much eliminated that. Ran noticeably cooler to boot. Gotta love 'puters. Full disclosure: I run a chopped and hollowed stock can with Supertrapp weld-on. YMMV. | ||

Good advice guys, Thanks | ||

If you want to swap your Buell race muffler for my Drummer, let me know  | ||

I've been wondering if there'd be interest around here in someone swapping out the race ecm and can. Huh, something to think about. | ||

I had the race ecm and race muffler combo. I sold the muffler and wired open the valve on the stock pipe. Runs great. Mine used to ping like crazy but it rarely does now. | ||

Orangelius, this was what I was thinking. Create some back pressure with the stock muffler. |
