Boondocker ACEL Fuel Menu

Is anyone using this menu on the M1000's with a boondocker.
My air fuel ratios are 12.3-13.3 under normal running but when I punch the throttle at any RPM the a/f drops down into the 10's.
I was thinking of using the ACEL menu to take some fuel away under acceleration.
If someone is using it, what is a general setup for this menu???
 
Yes, you can use it to remove (or add) some fuel during acceleration, but don't expect to notice a lot of difference unless your sled already has issues. Set Sns (sensitivity) to around 5-8 (lower numbers make it more sensisitve to throttle movement, don't use 0 or 1 or it will be on all the time!), DR (duration) to 5-10 (engine cycles to make fuel adjustment), and AM (fuel amount) to maybe -4 to -10.

You can keep removing fuel until the engine momentarily quits because there's not enough fuel to burn. Somewhere just before this condition occurs it seems to feel the most reponsive, but you may find that you will have to keep tuning this as conditions vary because sometimes it will hesitate and other times it won't. When you're close on this threshold it can be tricky to keep it running consistent, and for a little gain it generally isn't worth it, but it can be fun to play around with...

You can also add fuel (only recommended for big bore kits), but you likely won't be able to tell much difference until you add so much fuel it loads up - you will be surprised at how much fuel you can add before this occurs. Also, you will notice your fuel mileage decrease, so I generally don't recommend doing this unless you really need the extra fuel.
 
Thanks.
I think I'm pretty close on the tuning now but it just loads up on acceleration. I think just some fine tuning there and it'll really rip. Once it comes out of the acceleration phase it seems the A/f ratio is bang on and holding really consistent.
I'm gonna put the -4 for 10 like you suggested and also boondockers starting #'s are the same for this and see if it is a little more reponsive. My sesitivity is at 8 right onw and boondockers is 9 so I'll leave it where it is for now.
