octane light

I have a stock crossfire 2011 800 HO, and the octane light keeps lightning up. I know there is a reflash for the 2012 800 mapping but here is the thing. I bought this sled used and i called a local dealer to ask about the recall and they told me, according to my VIN its already have a reflash! It was to my understanding that reflash should had fixed this? Its very sensitive, is there anything i could do instead of using ****** octane booster??
