• 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.

ECU Adaptation ? Found on web...

Bumped into a Can Am dealer at a car show and they spoke of the surging that my Spyder had. Long story short, the dealer said they used the following procedure for resetting the ECU after upgrading exhaust, etc..

1) Extended battery disconnect (1 hour)
2) Startup and idle for 15 mins - NO DRIVING OR REVVING
3) Cool down for 15 minutes.<br />
4) Startup and ride it like you stole it.

Yep.. on disconnecting the battery:thumbup:
 
From what has been related here, it seems to be pretty much a wive's tale. Typically, such an action can empty the closed loop register, allowing the 15 minute run to repopulate it with new data, but that doesn't seem to happen on a Spyder. The myth came from the Hindle instructions to idle for 15 minutes. Those instructions were to "season" the muffler and burn off the manufacturing oils, not to reset the tables for the new exhaust. JMHO
 
Interesting. They must season all the mufflers then, as the manufacture and design isn't really much different. Perhaps after they assemble them.
 
My advice is that if you think this will help you, there is no reason not to try it. It costs nothing, and cannot hurt the engine in any way. Even if it does not do anything worthwhile to the ECU, it may have psychological benefits. ;)
 
Sometimes when a dealer or a layman doesn't know the answer they'll make one up to sound like they know the answer.:dontknow:
 
Similar procedure used on Goldwing. Sets learned engine parrameters back to factory. Has definitely worked for me and several of my fellow GWRRA riders
 
The tickler is if it's ever worked for a Spyder....logically I would think the ecu would have some adaptation ability, short of the ambient temp sensor. Oh well

Disconnecting the battery cable would work on older model cars with early ECU systems to clear codes and reset the system. Doesn't do anything for newer cars since the ECU is a closed loop system. You need a computer with software specific to that ECU to clear/reset the system.
 
Thats what Nancy was hitting on...I have a hard time thinking the hindle is a lot more restrictive than other aftermarket exhausts, which still makes me scratch my head as to what the secret is... I'm drawing the ecu and exhaust together in this..
