Had heard about it here, but didn't realize they'd go ahead and do it, I was more concerned with the shocks and the revs. If they will do any/all updates or bulletins just because I bring it in, I like that!

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.

How do I determine it's needed?m
Do symptoms have to appear or should it be updated automatically based on pd. bought mine new end of April 2012 RT A&C
QUOTE=Jerbear;474959]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.
