07 M1000 FULL SLP setup is bogging down?

[Team Snyder]

Ok, I took my 07 m1000 out for it's maiden voyage today and it has a few issues. I sent this question to SLP too, but they won't be back until monday. Thought I'd pick the snowest minds.

I bought the full SLP setup for my 07 M1000 (hopefully with the 09 ECU update). I put on the Y-pipe, Pipe, Silencer, with the high flow intake, and PCV. Used 77 MTX weights with their green/yellow spring and a 36/44 helix. This is on a new 3 post clutch with new 46 belt.

Now on to the issue.
It's clutched for 8-1000 feet, and I was below that and right on that with this issue. When I go along the trail between 4000 - 5100 RPMs for a while, then I full throttle it, it feels like it bogs right down and will only go about 6000 RPMs max. I don't know if it's getting too much or too little fuel. BUT, if I have it reved up at 5300 RPM's or greater and ride for a bit, I can full throttle it every time and it hits the power band no problem. It seems like the fuel map might be too rich at the lower RPM's. But I wondered what you techies would think.

I tested this out a lot today, I would be going around 5000 RPMs for about 10 seconds then hammer down the throttle and it would bog and max out about 6000 RPMS.. I would then bring it back down to around 5300 RPMs and ride that for about 4 seconds, then all the power would be back and I'd shoot up to my target of about 7700 RPMs. Almost seems like I burn the excess fuel in the system at the higher RPMs then it's good to go..

Ideas?

Does the powervalve servo motor work.

Check your servo and that the cable length adjustment is correct.

Are you using SLP's Map? Any Gauges?

 

[RockyMtn.Kris]

Im sure its fuel related. The powervalves open at about 6000rpm so you will probably have some fine tuning to do in that area. What fuel controller are you using, and what is your fuel pressure?

 

[KSH]

Please confirm your Powervalves are opening correctly, before you start reinventing the wheel.

 

[Team Snyder]

It was running flawless with no problems at all before the SLP setup, and I never touched the powervalves. I can check them today. I am using SLP's maps on a power commander 5. I don't have any guages on it, so I don't know fuel pressure or anything that way... unfortunatly.

Some of what your describing sounds like Powervalves, just double check everything is correct.

Was the map preloaded or did you install it?
You need to confirm the correct map is installed.


Please explain this comment. I bought the full SLP setup for my 07 M1000 (hopefully with the 09 ECU update

I couldnt get to it today, I had to cut a deer up, tomorrow morning hopefully I can pull the valves. The map was suppose to be pre-loaded on there, I suppose I could hook it up to the computer and make sure there is something on there..

That comment was just to say I took it in for the ECU update and they wrote it on the ECU as being updated to the 09 version, but it really didnt run any different after I updated it, so hopefully they did update it..

Did they also install heat shields and heat loom?

 

[Team Snyder]

Yea they installed some looms and a new heat shield by the coolant bottle and underneath the pipe...

I was reading up on the PC5 and all the documents that came with it and I found a sheet that said I should calibrate the TPS (throttle position sensor) on it. I never did that after I installed it on my sled. I basically just plugged it in and strapped it down.. Do you think that would play into this problem?

To get paid for the labor to install the shields they would have had to update the ECU.

Did you get a good ground for the PCv?
I grounded motor to frame, frame to PCv.

See what SLP has to suggest. Just confirm that the power valves are opening correctly.

If you can find no other reason for your problems, then check your TPS.

Yes, I would calibrate your PCV with the TPS for both idle and WOT. It is simple to do and could easily be your issue.

how do you calibrate it ? i have a pcv but havent installed it yet and would like to do this before i take it out for a rip

sounds like to much weight and or to much helix. It isn't back shifting.

If it will pull from a dead stop and pull through 5800-6000 rpm and hit the peak RPM's then when you ar cruizing and try to hit it and it won't pull. It is a weight or helix problem.

IMO

What I would do is pull off the hood and remove the clear plastic cover on the servo motor and try to do it again, but watch the servo motor and make sure it twist all the way open. I had on kinda do that and it was a cable starting to come apart inside itself just enough to bind and slow down the servo motor, (I would do this first) you can also disconnect everything and make sure the cables move free. If not fix it or it can wipe out the servo. I would also calibrate. Is this only with the pcv or do you do it with the pc III too.

this is for the PCIII but you get the idea

If I have it reved up at 5300 RPM's or greater and ride for a bit, I can full throttle it every time and it hits the power band no problem.

I guess will see here. But with this kind of reaction I doubt it is the PV's. But it could easily be the fuel mapping. On my 07 I had a similar problem and it was caused by the excessive fuel that the AC program was trying to add at the point the PV's were opening. Just before they open the sled will run lean. As they open it it dumps the fuel. I am running a BD box to fix this. If I don't have the control set just right it will over fuel and act like your sled is now.

Let me know what you find. We can learn something everyday.

X2.

If someone tries to add fuel to the mid range (6000rpm) to keep it cool for going down the trail it could cause it. What happens is before the PV open (6200rpm) the stock fuel map leans way out mainly to hit emissions, the sled reads the pipe temp sensor to accomplish it, so if you add fuel in the mid range the stock map just keeps pulling more fuel to compensate, but then when you break the rpm range and the stock map dumps fuel it also dumps the fuel added which could be your problem. But when you do it at a different rpm/throttle position it might make it through the map without a problem.

Ok, here is where we sit. I talked with SLP about this and here is where we sit.

He said to make sure your TPS is adjusted. So I went and calibrated it, my minimum value was about .725 and my ACTUAL was .625 and my max value was 3.725 and my actual was 3.425 so I adjusted those.
He then said to check your cable attached to the servo in it's natural state. And it should be 1.319 inches or 33.5 MM. I checked that and it was fine.
Then he talked about my Exhaust temperature probe and said if that was installed bad it could be defective and also be causing this. Well I installed it and I think I may have overtightened it when I did install this..
And I think that probe MAY be what is causing this. Reason I think this is when the sled was at rest for a little while it seem to run real good, but once everything heated up underneath the sled is when this problem really started to occur.
But, that probe is a bit costly, so I am going to run it out sledding sometime soon and test and see if my TPS calibration might have by chance fixed it, if not I am going to replace that temperature probe....

So... that's where we're at.

*while i'm thinking about this. SLP said that probe is hard to test if it's bad.. Anyone have some ideas on how to test that temperature probe?

 

[WyoBoy1000]

do you have the gauge that give readings from the prob, over tightening should not hurt it, I'm assuming your talking about the O2 sensor anyway. Its not likely it would go out in a hurry, how long have you had it.
