After spending the last few nights on the updated ECU setup for the 2007 and 2008 M1000s I can say that it IS an upgrade.
What I found is the fuel delivery is much cleaner and consistant. It gets rid of the backfire issue on the 2007 and the lean midrange of the 2008. No bogs or hiccups and seems really linear.
I tested it in the stock configuration, as it was intended and found that the sled pulled harder and more consistant throughout the RPM range.
I know the guys at Arctic Cat have spent a LOT of time on this upgrade and you have to remember that it was set up for elevation and for a stock sled. For that application it is leaps and bounds better than the stock ECU programming, not to mention the dismal 2007 upgrade.
Take your sled in and get it done. Especially if you are still under warranty, because the aftermarket warranty providers will check with Arctic Cat to verify all service bulletins have been preformed before aproving claims.
I have a whole bunch more information regarding various other configurations. If you have questions just PM me and Ill get back to you as soon as I can.
