I believe the BUDS will automatically tell if you need an update and recommend installing it every time they plug it in...
That said, ever since I did the 3 main spyder fixes, I have no more hesitation, surging, backfiring and general crankiness I used to have...
- Disconnect the purge value / Cannisterectomy - this made a HUGE difference. (BRP won't ever recommend this because it's an emissions item)
- Clean the oil out of the airbox and stuff some foam in there - Maybe cleaning it made me feel like it ran better... (btw, my dealer said that BRP is actually recommending this now in a tech bulletin)
- Ride harder! She comes alive with higher RPMs. To heck with the noise, downshift!
I did the Spyderpops Missing Air Dam... at long lights it seems to take longer before it gets hot
And I needed plugs at only 3k miles... from babying it too much

pps:
So that all said, describe everything to your dealer. Be firm and let them know that you don't like the way it's behaving and that they need to fix it. They should be able to help, if not they know where to go for help. If they still can't help, come here and someone will recommend a dealer who can
Outside of dealer help, the Cannisterectomy made such a big difference on both of our spyders that I can't help but recommend trying it out. Here's Lamont's video: [ame]http://www.youtube.com/watch?v=huC0pXtPcug[/ame]
It's painless and very easy.
The 2nd Update modifies the behavior of this valve and relocates where the evaporation cannister vents to. Eliminating it makes the update unnecessary. Eliminating the cannister also makes relocating the vent unnecessary, but still a good idea if you don't like the smell of gasoline... or spontaneously combusting spyders
(p.s. I like lists! :joke: )
