Thanks for the words, happy to be of help/service.After a year and 8000 miles, I finally splurged for Todd's modified ECU. I wasn't completely dissatisfied with the stock performance, but the surging and popping from the lean jetting was an aggravation that I wanted to correct. Just wanted to confirm all that I've read on here, the modified ECU really works. It's not magic, no fire-breathing race bike, but it makes the bike perform like it should have from the factory. Just riding around town is so much smoother and less jerky, and I'm sure it'll be the same on the highway. That was worth the money by itself, but knowing my motor should run cooler and last longer makes it a no-brainer.
Just an aside - I pulled the bodywork to get rid of the charcoal canister and the extra plumbing. After reading all the info here, I was confused to find my hoses coming off the canister didn't jive with everyone else's. No check valves, no Ts, the hoses weren't connected to the throttle bodies. I snapped a couple of pics and sent them to Todd, and he confirmed that someone had already plugged the TBs. Weird, as I bought the bike new, and my dealer (who dropped the Guzzi line shortly after I took possession) never struck me as knowing much about the brand. Can't imagine they would have performed the surgery on their own initiative.
A mystery, but I sure won't look a gift horse in the mouth.
Appreciate the words and endorsement!
