GT-RX Performance ECU

[FrostedFlake]

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. Now if I can just figure out all the VDST can do...all I've had time to do is the TPS reset after reinstalling the ECU.

Just an aside - I pulled the bodywork to make getting to the ECU easier, primarily because I needed to remove the tank cover for a warranty replacement anyway. While I had it apart, I decided 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.

Thanks for the words, happy to be of help/service.
The VDST is a bit of a love/hate ordeal. There really is no training to be had, it's a "learn as you go process"... hopefully the Q&A info here on the Forum is helpful. Formal modern trained mechanics can dance through it with confidence, however it's a useful (near mandatory) tool for weekend garage warriors, and those who simply don't want to have to go to the dealer every time the bike starts running a bit "irregular," as well as, it being a good point of reference for home diagnostics through the Forum here.

After having fork issue resolved I've been able to put about 150 km on the bike. First ride(s) with Todd's reflashed ECU. Bike is much more responsive and smoother. Starts much better as well. Mechanic who test rode my bike after fork replacement was highly impressed the throttle response. Nicely done Todd,well worth the $$. I am very interested to see the transformation once I get the PC-V and AT installed.Highly recommend the ECU reflash. Thanks Todd.

Does the re-flashed ECU negatively impact fuel mileage?

Hi There, I am in need of help since I purchased a 2009 Stelvio 4V a few months ago, it was only 2200 KMS just broken in, from what I read it looks like there is a consensus on how jerky and kind of rough the engine works on original settings from idle to town riding. actually I am experiencing this myself and I look for a fix. As I had only one ride on the bike before going away to Europe I did not study much the problem at that time. I went to the Mandello del Lario in Italy where the factory and the largest Guzzi dealer are: Agostini, they recommended to change my air filter with their new unrestricted polypropylene unit and also to get a new muffler, which I did, once back in Canada I installed both but the difference from stock does not make the cut and I am now reading about the possible change of the ECU that seems to make some nice difference. Could somebody help me in this regard so I will get a smoother running bike!

Thanks in advance

Only if your right hand allows it... once you can enjoy the bike for how it should run. Generally speaking, mileage improves from most all those who have posted in this thread.

I see Todd already replied to you. Do not hesitate to purchase whatever he has recommended. Once you have Todd's products installed, you will absolutely love the way your Stelvio runs. I couldn't be happier with my 2009 Stelvio. It is the best bike I have owned in over 40 years of riding.

Cheers,
