jamesearl, I have two other tunes I was using for "Touring" on the same bike, and neither one had the rev hang. Pretty sure it's just this newest tune I'm working. I know, why don't I just compare the tunes right? Did that, and pretty much the only major differences are in the timing curve tables above the rpms where I have the rev hangs. So... been playing with the VE Tables in the "0"Throttle Position column at the range between 1750-3500 rpms. Added about 10% more fuel there and calmed the rev hang down considerably. I'm just hoping to find someone with a bit more experience than me that can tell what I need to do. For example; add fuel to the "2%" Throttle Position too, or maybe I'm not covering the right rpms. I can't be the only guy trying to sort this out on a 13yr old SERT. Maybe you can help me get this question out to other members? I can't seem to post new threads yet.
