RHIP Posted August 27, 2008 Share Posted August 27, 2008 I have a chance to put a set of Staintunes on my Rosso - will this require a remap of the ECU? Anyone with any experience with this system? Thanks! Link to comment Share on other sites More sharing options...
Tom M Posted August 27, 2008 Share Posted August 27, 2008 If your bike is stock except for the Staintunes you should be OK. If you change the crossover and/or the intake you'll need to richen the fuel map. Link to comment Share on other sites More sharing options...
kewells Posted August 28, 2008 Share Posted August 28, 2008 My bike came with a set installed, so I have no idea what the PO did, if anything, to the ecu. I have the stock headpipes without a crossover, so all may be stock. I can say that they sound great, not obnoxiously loud, and they are very well constructed.

stucatz Posted August 29, 2008 Share Posted August 29, 2008 For what it's worth, I installed Mistrals and a crossover with no additional ecu or re-mapping. Bike sounds great, pulls great, no issues. No hesitation anywhere and gas mileage appears to be the same as my buddy's stock V11. In addition I installed K&N air pods. Just lowered the idle a touch and voila..... Could it be we make too much of this whole ECU and re-mapping issue? Link to comment Share on other sites More sharing options...
raz Posted August 29, 2008 Share Posted August 29, 2008 Could it be we make too much of this whole ECU and re-mapping issue? Possibly. If you switch cans and it runs great, why bother? There are numerous reports that the V11 stock mapping actually seem better suited with an aftermarket exhaust. Ryland is the perfect example, he dyno'ed the bike and the map was perfect without a change. That said, if you replace your exhaust you should be prepared to remap the bike.

Fred C. Dobbs Posted August 30, 2008 Share Posted August 30, 2008 I don't have any experience with Staintunes--I have M4s on my Ballabio--but assume they are less restrictive than the stock cans. My bike ran fine after the change, but I noticed that the plugs looked as if the engine was running pretty rich. I talked with the mechanics at Moto International. They explained that (typically) aftermarket cans installed with stock mapping cause the engine to run rich on the low end and lean on the high end--perhaps dangerously so. Micha set me up with a Power Commander and now the plug color is perfect. Seems to pull a little harder throughout the rpm range, too. Might be worth taking a look at your plugs after running with the Staintunes, or call M. I.'s tech line--these guys are great. Good Luck Link to comment Share on other sites More sharing options...
