OK boys, here is the latest. Arctic Cat just released a new programming unit that allows all Arctic Cat dealers so update ECU programming at the dealership!!!! This is going to be pretty cool. As far as the 2007 M8 goes, you should get your ECU updated to the 2008 specs. There was a reflash on a certain number of 2008 M/F800s, but did not affect the 2007 models.
