I'm trying to diagnose some rough running on my '07 990 adv. At idle the exhaust at the left pipe seems to be sputtering and weak. I already set the TPS to .57-.58v hot and sync'd the TBs as best as possible by matching the TuneECU map values at idle. I was checking with tuneecu and I see the following: http://www.flickr.com/photos/89427113@N03/8140337285/in/photostream/lightbox/ Given that there seems to be a difference in how the two cylinders are running, based on the exhaust feel and sound, the two different values for 'Injection pulse' seem to jump out. ~2.6 on the left value and 3.1 on the right value. I also noticed when I first started the bike the O2 reading on the left read consistently lower than that on the right. Does anyone know if this is normal? Anything I can check/test?
