Engine Tech 900 M7 specific tuning information

[vinpie1]

I have searched over and over again looking for m7 specific tuning information for Engine Tech 900 big bore engines with no luck. The builders #'s are so rich they wash the plugs. I am asking others to share their specific setups and #'s if they have them. I just want to compare them against mine. Also wondering what rpm this motor likes best up in the mountains. Single pipe or twins? I have both.

Anybody?

I just purchased a 2006 M7 w/ engine tech 900 kit on it and Jaws big bore specific twin pipes. I'd like to know what anybody else is running for jetting for 3-6k elevation?

When I had my ET900 with twins, I called Racing Station and had him create a map for the Power Commander, was tired of messing with numbers.

I called during the busy part of the season and didn't have any luck acquiring the map.

Here's the numbers I'm running in my 06 m7 with a Cutler 800 and slp twins. I could dial it in a little better but its good to ride.
RPM LO MD HI
3000 -2 -4 0
5000 -2 2 0
6700 0 6 0
7800 0 4 14
8100 0 4 14

Comparatively you're using a ton more fuel in the middle than me. In theory no need to add to the low setting after 6700 because the throttle position will be in the mid to hi range and you don't need to pour more fuel to it when chopping the throttle. It'll run rich when working the throttle set up like that.
