That's what I'm talking about!!! I sure hope it is a fool proof fix. If so I will have the sled I really hoped I was buying.

Funny, I said that earlier in this thread and was told I didn't know anything about engines for thinking that way.

I am running a push turbo with the power commander. So far I have had no issues. I wonder if the power commander has anything to do with it? I turn the key an wait for all gauges to cycle. After about 5 seconds my afr gauge goes to mid 14's. I turn the key then and it fires right up.

If I remember right and I may not, the thought was a bad map would affect all of us not just some. BUT, a bad flash could cause some to not work and others ok....remember Ski Doo 1000 that had a lot of units that had to be reflashed (I had one).

Either way, it's a computer problem. Not something I can fix in my garage. Most of my background is carbs. Pretty new to four strokes and very new to fuel injection but that doesn't make me an idiot.

Guys, I grew up with carburetors and breaker points... What's a "Flash"?

When the computer on your sled is programmed for specific characteristics a program is installed "or flashed" into the computer. Say you want rev limiter up to 9900 rpm you can have somebody with the equipment "flash" new instructions into your computer.

Sorry if you took it that way as I certainly didn't mean that.

No worries, just glad there are people on here willing to brainstorm and try thing to fix these issues, small as they may be.
