08 M1000 - Crazy BD Box numbers???

[pinit]

my numbers are quite high as well had to add a bunch to slp's numbers. I also learned another very important thing while tunning. When I was out yesterday I was unable to reach 7600 rpm (to much weight in primay and may have a bit to much helix) any how since I was unable to reach the 7500 rmp range in the box did not pull much fuel from that area and found the sled running very lean. After thinking about it for a bit made perfect sence if I'm putting full load on it but only running 7200-7300 I'm going to be pulling my main amount of feul form the 7200 area. At 7200 with slp's set up not adding much fuel. This efi stuff is a new learning curve not any thing like the old carb sleds. Hope I can learn fast enough that it doesn't cost me money Rodger

It's interesting that no two sleds seem to be exactly the same. I don't find your numbers on top that crazy at all. Mine are very similar. I have to run the big numbers on top to keep the EGT's below 1200 degrees. My powerband is smooth as butter and it pulls like a freight train, so I've never been concerned about the numbers as long as they work and I don't burn down.

However, on the bottom I have to run negative number (3000: -03, -03, 00; 5000: -01, 02, 00) or else I load up after idleing too long, coming back down a steep hill, or going slow through the trees.

My sled is an 08 with the SLP single, RKTek head, and cutler cold air kit.

Outlander800 I also found that I had to run similar numbers on top to keep egt under 1200. I did a plug check had pto egt reading 1205 and the mag side reading 1178. pto plug had a light/dirty grey line in the bend of the electrode. the mag side was more on the brown side but still light. So my thoughts are much over 1200 on a hard pull and your playing with fire.

I have also niticed that the sled wants to load up down hill and idleing. I think that I will do as you have and remove some fuel in the 3000 and 5000 rpm ranges

After I got my egts down where I felt comfortable 1150 range . I gave it a hard long pull, I was impressed this thing just keep on pulling. In a 16-18 secound wide open pull pinned to the handle bar this thing never flattened out. I gain track speed the hole way up the hill.

this is the best part I still have more to come as I was about 400 rpms short all day.

what do you think the afe should be? 12.5-13 is just right in a long climb

 

[mrquick68]

OK - more info to report.

Built a nice little Boonie box mount right on bars that turned out quite trick. Couldn't sleep one night, and went to town in my garage. Thought i was gonna wake the wife with all cutting and grinding!

anyway - i still CANNOT get ride of this f'ing bog. used the capature mode (cool!) and was able to determine the bog to be a MID throttle and always right around 5300 rpm - checked it 5 times. always the same. Just where i thought it was.

I ended up liking Mtn extreme's numbers, but tried moving the MID 5000 up and down and it NEVER fixed the problem. leaner seemed better than richer, but i dropped down to as much as -5 and she still bogged!

here what i was running (give or take):

3-.....-01 00 00 00
5-.....02 -03 01 00
65-...02 02 03 00
72-...00 01 03 00
75-...03 05 16 00
78-...07 12 23 00

Ahhh!!! Why can't i get rid of this damn BOG!? Any ideas!? Sled RIPS every where else in the power band and climbs like a billy goat on crack - just sucks on thet trail.

Possibly unrelated - STILL blowing belts too. well, pulling threads anyway. Frustrating for sure. Always the outside threads - even shimmed the motor over to help combat this. BAH.

help

not trying to hijack this but you guys really seem to know whats up so.........

here's my problem: i have avoided a boony box for 14months and now i'm pulling the trigger. Heres what happened.
08 m10 153-1500mi stock motor
SW ypipe, stock pipe, qcan. BDX cold air intake, stock clutching 75g w/ shift assist.

Sled has always been fat, and boggy. Throttle response changed incredibly with BDX intake, but bog is all over the place.
Normally, i always ride at 10k all day and got use to feathering around the bogs. But yesterday, i rode from 7400 to 12,300.
In the morning unloading at 7400 the sled ran awesome, perfect pulling ape as i climbed in elevation and the air temps rised to 35 deg and 12k the sled started running worse to horrible!!, barely could pull 6800 on 060 belt. went to 046 and regained 200rpm but little power. As the temps went down in the late afternoon, and we dropped in elev the sled cameback to life. By the time i reached 9000-8500 elev the temp had dropped 20 degrees and the sled was pulling harder than ever! By the time i got to the truck, it was again the lowest elev and temp of the day, and she was pulling harder than ever in 14months. I am ready to buy a box, but which one? Pure Logic for a 1st time tuner?

thanx in advance,
ray

more to report. Still have the bog though:

finally got to get out riding again. Ended up with the following numbers

3000 -02 00 00
5000 00 00 00
6500 02 10 04
7200 02 03 06
7500 03 10 18
7800 03 10 25

So, here's the scoop... BOG is still there, but trail in was MUCH smoother. was able to really see where the bog is, perhaps easier to dial in because my gearing change??? My AFRs are strange though (i'm giving it time to settle too). at the 5000 LO & MID ranges i'm around 12.0 (rich!) but at 6300 where the BOG is i'm lean at around 14.4. I added all the way to 10 at this point and STILL bogging.

So, where do i go from here? Thinking that i may need to pull fuel at 5000 LO and MID but add more 6500 LO MID.

Any thoughts?

I still feel lean up top as well. I need to add more fuel i think.

 

[mtn_extreme]

PP,

My personal choice would be a boondocker box for your sled. It is more complicated for the user but once you understand it, has alot more precision adjustments to control your fuel flows. It just takes time to learn it.

Ask MrQuick as he started with another box and ended up with the boony.

 

[mtn_extreme]

Quick,

You might get away with that. Another option would be to program your Accel mode to spike fuel at that rpm range.

 

[mrquick68]

Quick,

You might get away with that. Another option would be to program your Accel mode to spike fuel at that rpm range.

please explain how to accomplish this. i've got the fuel only box (didn't know it had less features besides no NOS), so i've got no TPS option, though i do have the ACCEL feature. WHich i thought could be programmed to come on at a certian duty cycle for a certain amount of time. but not at a certian rpm for a certain amount of time???

 

[slyrydr]

i wrote down the bd #'s that someone posted for an 09 1000 with a full slp exhaust system from a couple of months ago....just posting the 5 & 65 rpm range.....5/ -3-5 0, 65/ -5-9 0......i modified this for my 09 with similar mods....3/ 0 0 0, 5/-3-6-4, 65/ -1-2 0, 72/ 0 4 8......the mid settings at 5 and 65 k show a noticable fuel pull, and mine ran much better with minus fuel in the mid throttle position....i think i could use a little less fuel in the 65 mid position, but my egt gage went out on me, supposed to have it back from the manufacturer later this week.....but you could add, say 6 numbers to the mid throttle position at that point and see if it gurgles bad, then pull numbers until it runs clean, backing up with a/f or egts....

 

[mrquick68]

good stuff.

Thanks for the help gents.

I might be out riding tomorrow, so we'll see if i can dial this bog out.

 

[jeffro]

Great info guys! A couple of questions for mrquick...

What elevation are your riding at?

Has your ECU been reflashed?

SLP recommends: mid -10 & high -10 for 7200 RPM. You're at +3 & + 6, Did you start at SLP's settings and it was WAY too lean?

and did you ever dial the BOG completely out?

My '07 M1000 ran GREAT before the 2 "warranty required" reflashes that messed it up. <sigh>

-Jeff

 

[Ausm7499]

Got a question for you guys. Like quick I also bought a Koso A/F gauge and had issues with it and have sent it back for a reflash so I have no way of monitoring my mixture. I just recently installed the SLP setup and RKtech head on my 08 M1K the head is 13.62:1 and I am running the stock intake with the 2cool dash intake kit as well. I have a friend that is running an almost identical setup on an 08 M1k the only differences are that he is not using the stock intake instead he had flow rights in the air box and a screen over the intake hole. His head is a litte more agressive its a 13.9:1.

We are both running a boondocker box and he gave me his map which is a little leaner then SLP recommends for and intake mode stock head and full single pipe setup. Here are his numbers

0 0 0 0
0 2 0 0
0 -1 -1 0
0 -2 -3 0
0 9 13 0

I have checked my fuel pressure and it is 46 psi.

Is there any reason I can't run these numbers without burning it down. I can't think of any variables that would cause me to be leaner then him but I am very nervous about not running a gauge to monitor my mixture.

Any advice would be great.

 

[WyoBoy1000]

quick, Have you tried to get it to die while bogging, if it will, do it and check the plugs, should be pretty straight forward. Or making it bog for a little while and hit the kill switch. I'd go off of plugs on the top end, who cares where your number are as long as it rips. I notice you never had the low range in the -negative range is there a reason for that.

I have a very similar set up 2007 m1000 full slp exhaust, bd box, timber intake, rk tek head, with end of last years ecu reprogram which is why i had to buy a bd box cuz my sled wouldnt run at all and my dealer said idk. Anyways, 38 helix, green sno pro spring, 162 and i have been getting her dialed in and having the same problem as mr. quick.......i thought i had some decent #'s until friday at revelstoke. no fuel pressure regulator btw..
3000 -03 -03 -03
5000 -03 03 -03
6200 -01 00 -01
6500 00 -01 -01
6850 00 -01 -01
7250 00 -08 -08
7850 00 06 09
I usually ride 2500 to 5000 ft and it has been a little fat in the 5000rpm to 6200 range. i left the parking lot at 1600 ft got up the road and at 2900 ft on the altimeter it seized up at 5000 rpms' and ruined both cylinders... i thought like three numbers was one jet size? -03 to 00?

 

[jeffro]

1500- Those numbers look VERY lean to me for such a low elevation. They might be OK for over 10,000'... IMHO

i know it went lean i think at the low 5000 # obviously since it blew but its been irratically fat seeming at the same #... it blew up at 15 mph going down the road slow on and off the gas. talking about the lo # starting at 7200 and higher, why would you ever want to be at anything except 0? when are you ever at that rpm and not pretty much wide open? i thought if you had any positive # there it would go fat when on and off the gas? i know i took off from a lower elevation than i ever do and it was colder than usua, i just never blew up and engine because of a lean needle ya know... and i thought i was a master engine blower uppppper!!!

All of your numbers are to lean, when it felt fat did you ever pull a plug to verify. I don't know of any one running that lean.

Way to lean. I ride 07 m1000 with reflash and slp y-pipe and pipe and can. I pull 1150 on the egts at wfo on a long pull plugs look good. For some reason or another I have a mid range lean and if I try to richen in up around 5000 rpm it bogs. So i just watch the temps and blip the throttle when I am on the trail. Now if I code only get my clutching solved still blows belts.
