2011 yz450f GTYR snow bike tunes?

[gunnin88]

I know I saw a tune some where last year for the cold and altitude. Does anyone have a good one they would share?

IMO the gytr tuner doest have enough range or adjustability to handle the botched mapping for cold

I gave mine timing across the board to liven it up as best i could then threw a Dobeck Gen 4 on it to handle the fueling in the cold.

I'm running a Yosh full exhaust and just a pre-filter on the stock cage w/backfire screen. I have larger openings on the intake shroud than stock, so I have really good air flow in and out. I was actually surprised to find I had a pretty severe lean pop on WOT before I adjusted the fueling to these settings. It now pulls harder than ever.

I just wanted to update. It was a fairly warm day when I tested my tunes out, and after riding a bit more, with different conditions and fuel, I found that running premium pump gas, with my mods, my best all around tune is stock tuning. (all 0's) It's about perfect. I still get up to temp, have awesome power, and have a slight lean pop on deceleration every once in a while. Perfect I think!

I'm running the same intake system as Jacob with stock exhaust and currently have the "jay marmont" race map programmed. After enclosing the engine and blocking a rad all the over fuelling problems seem to have stopped.


Here's the map if you want to try it out, has pretty good power.

Best tune for snobiking is "fat bottom girls" ! It says, "get on your bikes and ride". (Queen).
Best map, Jay Marmont.
