I see this option in ECMspy, I was wondering what it exactly what it does and if it is safe to use? I know my truck has this, where given a certain throttle position and RPM, the injectors will significantly reduce or cut-off the fuel into the cylinders. Seems to work nicely with engine braking and fuel economy. Is this option of any use on a Buell? Just through I'd ask before I blow up my motor. |

I read in the EcmSpy how to guide that some fuel is needed to keep the combustion chambers lubricated. Something like that. I wouldn't do it on because your truck is liquid cooled and the bike is not. Just my 2 cents. Their is an area in your fuel map for that particular use. "closed throttle overrun" If you wanted to try lower those numbers steadily to see if it has any positive/negative effects on the engine. It actually says in the guide "never remove all the fuel in this area, as you need some to lubricate the engine" Their is also the "high Speed Closing Throttle" zone, but it bluntly states that it is critical to keep fuel in that area. I just let VE analyzer mess with my maps. It seems to have worked very well thus far. Virtually no popping on decel. My AFV doesn't float above 105 or below 95. It was as high as 112.

Yeah, I read that too, but maybe it doesn't completely remove the fuel? I reduced the values closed throttle overrun area last week by only 3 points to see if it would improve the popping and it actually made it worse. Not sure what to do about it. I'm going to datalog some data today and see what Megalog can do for me. |

That's your best bet IMO. I did a lot more rides/VE analyze that what the how to said. Probably 8-10. I'm also half tempted to mess with the redline. I noticed the most up to date version of EcmSpy lets you. But I don't want to risk it. (Message edited by mr2shim on June 15, 2008) |

You definitely don't want to pull out all the fuel, as these are air cooled engines they definitely need the lubrication to prevent damage. The ve-analyzer with lot's of logging are the way to go. There's a ton of info on using/tuning with ECMspy on the UK version of BadWeb www.ukbeg.com Good luck and happy tuning! |
