There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

New Spyder ECM & TCM Software Update!
On June 19th, BRP has issued a new bulletin that updates the Throttle Bodies, ECM & TCM on 2011 and 2012 Spyder Roadster RT's. The throttle body update (Bulletin #2012-4) has been out for a bit and has now been grouped into this new bulletin (#2012-10).
Here are some details about the ECM & TCM updates:
Roadster RT ECM Update:
Improvements of limp home mode for VCM triggered codes:
Two types of engine limitations are now available:
1. Speed limitation.
- If unit speed is above 50mph, speed will be limited to 68mph, with no rpm limitation.
- If the unit speed drops below 50mph, the rpm limitation will take over as described below.
2. RPM limitation.
- If limp home appears below 50mph rpm will be limited to 4400rpm for each gear 1-4, 4200 rpm for 5th gear. This give the unit a max speed of 56mph.
Other ECM improvements:
- Improvements to limp home reactions and warning displays in cluster.
- Reverse actuator is now controlled by the ECM rather than the cluster.
- Gear learning has been improved to be more precise.
- P0504 and C0040 codes now have a better detection of faulty component. The calculation of deceleration has been integrated.
- A filter has been implemented to remove the cruise control deactivation by a VCM brake signal random spike.
Roadster RT TCM Calibration Update (SE5 Models):
The riding condition that has been identified as responsible for premature clutch failures is prolonged driving between 2500-3300 rpm. Between these rpms the centrifugal clutch is not fully engaged (clamped) causing clutch slippage to occur when load is increased. Slippage produces heat therefore causing warpage of the steel plates and damaging the friction plates.
The new calibration offered can be easily compared to a kick-down of an automatic transmission car under load (or acceleration).
The new calibration recognizes an increase in load in the identified rpm range and will initiate a downshift therefore increasing the rpms out of the risk zone and giving the centrifugal clutch its full engagement force to prevent slippage.
This calibration change will be noticed mainly by customers riding in the risk zone, customers riding at higher rpms will not notice a significant change.
This calibration downshift will occur from 5th to 4th, 4th to 3rd, and 3rd to 2nd. A downshift from 2nd to 1st gear is less probable unless precise conditions are met since the "kick" is a bit too aggressive.
This calibration will not affect the habitual auto-downshift of SE5 at 2200-2500 when throttle is released in normal mode and at 3300-3500 in trailer mode.
If the load request that intiated a downshift is maintained and an upshift is requested by the driver the unit will not upshift until the load request is released or rpms are higher than the predetermined curve.
This file can be added and removed using BUDS at the dealer. However, BRP strongly recommends every 2011/2012 SE5 unit to have this improvement activated.
Trailer mode will still be available and recommended for units hauling trailers.

I have had it done and the only thing I have noticed is that if I fall below 3000 rpms and give it some gas it will down shift to a lower gear. This has happened to me twice, I wasn't paying attention and went below 3000 rpms and gave it gas it downshifted to a lower gear.
When I had my RS, it would usually down shift when I was accelerating out of a curve and it would throw me back and I would twist the throttle and not mean to. This would make for a bad ride for the moment. The first thing I noticed about the RT was that it hardly ever down shifted on it's own unless I was coming to a full stop.
I watch my tach and will down shift manually to keep the Rpm's around 4,000 to 4,500. If I get this update and the bike's shifting and my riding style don't get along, can I have them change it to take the update off? If I did that, do you think it would be harder to get work done under warranty? That if something were to happen, they could claim that since the update wasn't done that they would not cover a repair?
Just thinking out-loud as I'm used to shifting and wondering how this will effect me. Sure don't want to go back to the way the RS automatically downshifted too soon.

I like you stay in a higher RPM range. Don't think you will notice any real change. :thumbup:

They can void your warranty if you sit crooked it appears. Or at least try:yikes:

If what Jerbear has stated is true, I doubt it. If one of the reason this update is done is to prevent premature clutch failure than it is unlikely any dealer will "undue" a mandatory update issued by BRP.

I'm gonna hold off getting the update till I hear from some others who've had it done. I tried the trailer mode when in the mtns recently and it was way too aggressive to suit me. I'm sure the new update isn't that bad but want to be sure as I'm doubtful I could get it changed back. Even if a dealer would, I'd expect to be charged and with their flat rate it would be an hour labor @ $90 per at my dealer.

I have had the update and if you are above 3000 rpms when you give it some gas you will not notice any difference. I have also read the instruction manual from cover to cover and no where in there does it mention about always running high rpms. it just says you have to be above 3000 rpms to shift gears. And the dealer sure didn't tell me anything about how I should drive it. I now shift at 4000+ rpms and always keep it above 3000. But I would have never known to do this if it were not for this forum.

I just started shifing at 4k+ and downshifting approaching 3k
and my gas mileage went from 29-31 to 34-35... about +15% !!
I guess when lugging the engine, more throttle was needed to get moving faster.
Also, it's nice having the full torque available, too...
Having the update done Tuesday morning.

Wut he said! Should be interesting tomorrow, winds are outta the south, 15-25 mph. Should be able to get some idea if setting the shocks at 5 does anything.

I had the update done last week on my 2012 RT and did not see any difference normally. When I let the rpm drop down and then tried to accelerate, it downshifted a gear to get the rpms up. It is a nice feature for anyone prone to run at low rpms but I think most experienced owners will rarely see it kick in.
There should be no charge at any dealer.

I had the 18,000 mile check done yesterday on my RTSM5. It's really now a check at 9,300, instead of 6,000 and there are several things every 14,000. Of course, this happens when the new oil filter(s) get installed.
Anyway, they hooked up the BUDS and it did it's thing. I had the throttle body update done 6 weeks ago or when ever and the only thing I noticed was that the cruise is now almost perfect. It use to lag going uphills and lead going down, but now it stays within 1 mph. No "limp home" lights (ever, at least so far) so I can't remark on that.

There is no way short of having the dealer hook it up to BUDS, I'm afraid.
Is yours an SE? See if it downshifts as per the bulletin in post #2.

Got mine done today at Reno's PwrSprts KC. My opinion of their service went up a bit. Had a 10 am appt., didn't get to it for a while, but they were having Yamaha demo day, so burgers and hot dogs :bbq:were on the house. They did the TCM/ECM update, something with sealing the radio, and I had them move the shocks to 5. No charge for any of it. Guy at the desk said, "As of 12:47, 30 June you are up to date." Seemed a lot better in the wind on the interstate. I'm not a twisty rider, but I have been making an effort to keep the revs over 4K, so the only time I really noticed anything was a semiquick stop at a light, multiple downshifts one right after the other as I was just trying to stop it.
