I'm stumped. And so is Artic Cat. Help.

[eludnu]

I've been posting in the turbo section as I'm dealing with a 2008 M8 that happens to have a BD Race Gas Turbo on it. Long story short, the dealer I bought it from (Outdoor Toy Store) went under, and never really finished it. At least I got the Sled.

The bottom line is the power valves refuse to work. I have tested EVERYTHING associated with the PV's and check it all per manufactures spec. The injectors also are within spec as far as AC and DC voltage are as I was testing for ground issues.

So the wierd part. It's throwing a code that Arctic Cat SWEARS it cannot throw as it was never programmed, and that's coming direct from the factory. Code 08.

I know I could go with a BDX delete kit, but being that it's a turbo I don't really want too. To make matters even more odd, my local dealer was kind enough to let me use the AC computer to test my sled. It failed to even see the sled. Generally as I understand it this would be traced back to a CCU issue for over or under voltage. But I've tested both a new CPU, CCU, and even display, and all my lights work. Stock headlights. I'm pretty sure I'm whatever it is will be a small thing, (like a crushed wire, or poor ground) but I have checked everything I can think of.

I also asked Boondockers if I could install a set of STM power valves and it stumped them, as no one seems to have asked them that before. I don't really want to be the first one.

Anyone ever had the AC computer fail to "see" the sled? And if so, what did you do?

Sorry for the long post, but short of installing a complete new harness, I'm stumped. And I'm not sold that this will solve it either....

not a cat guy but whats the chance the computer was damaged from someone welding on the sled when the turbo kit was done? I wouldnt think it is a harness problem..a shorted wire would most likely throw a code for the affected circuit but not shutdown the computer from a scanner reading it..or maybe the computer is a "race" computer that some how or another got put on the sled by accident?
any chance your dealer will let you plug a known good stock computer in just to see if the scanner can see it? that would sure cut down your area of problem....

Good thinking. We did pull a CCU from a 08 M1000 (same unit) and eliminated that as the problem. I also did the same thing with a brand new out of the box CPU, that had all the same markings, and updates.

It is also throwing the code for the PV's but I'm not too concerned about that one, as I know when I find the solution for the other issue, this one will go away. Solenoid is not the issue, and cable are perfectly dialed in.

Oh, and the sled runs like a raped ape, rev's out, and spools the turbo. (I ran it in my field for a couple seconds) thinking maybe it just needed a good handfull of throttle...

well if it runs good....just pull them bulbs out of the dash..... did you inspect all the connector pins(inside every computer connector)? I have seen guys bend the pins over and cause all sorts of headaches...you might also want to try something called stabilant 22A..its designed for rescueing computers from water..really enhances connector contact....I have fixed many computer related problems with this stuff....http://www.micro-tools.com/store/item_detail.aspx?ItemCode=22

 

[eludnu]

AK, believe me, if I thought "pulling the bulbs" was an option I would be all over it! The valves still won't work, and now I'm pi$$ed that this thing is kicking my rear.

Yup, checked all the pins on every single connector......

wish I could help ya more..best thing I can say..pull that harness,lay it out on a table and look it over really good...one thing you might check is for ac on the dc side of the regulator..if the regulator screws up you can put small amounts of ac in the dc side..wrecks havoc on computers(I had it happen on my edge sled and it killed a gps..just fried it...

Ground

It is electrical
check Bd Grounds make sure it is hooked up..
Bd uses a yellow wire that hooks to servo motor if it is grounded it could cause this.

It sound like you have maybe more than one issue if you can get i to us we would be glad to help.

 

[mmsports]

One more thing

we have seen that some time when Exhaust temp sensor goes out it will trow fathom codes change it out.

 

[m1000flatlander]

the computer thing can be one of two. that system use two cords one that will work on a sled without a battery meaning you will have a black and gray cord holded together and battery will hold to the clips and the other just the gray cord which goes on sled with batterys. but my experience is to hook the cable up then hook to module then hook usb and last plug into computer. one with that system best to compare a good sled with a bad one(not the greatest imo).

 

[RACINSTATION]

Like mm says, I too have seen the exhuast temp sensor throw an 08 code. 08 does not exist, but I have seen it. The other time I have seen 08, the machine had a pinched wire under the gas tank going to the power valve servo motor and it was grounding on the tunnel.

 

[h2otoyz]

was this sled ever ran stock? did it run fine before the turbo if so? (not sure if you mentioned this?)

sounds like a ground to me... check the wiring back by the tail light harness, we had one where the factory ran a screw right into the wiring and it was a complete nightmare up until the point we found it. turns out that has happened a few times as i read a couple guys had that happen to them on here as well, i think darko was one of them.

i'd check the harness over extremely well. the power valve issue might be something completely different.

M8 problems

Check the harness, under the tank they get shashed, I have had one blow an ECU, CCU, servo motor before, we had to install a new harness. Also, we had a 08 M8 SP recently, that had to have the same things, except the CCU and servo motor. Also check the chassis ground on the left steering post support tube top bolt.

Wow. You guys are awesome. I'll see if I can remember everything you all asked about.

First, the sled ran perfectly last year, by all accounts. If you've ever seen the sled, it's one you remember, and I'm told it flat ripped. I picked it up with about 300 miles. I'm not sure how many were on boost. Installed fresh pistons just to be safe, and the turbo fully removed and inspected, and updates to BD box (Not verified)

I did check the yellow wire to the solenoid as it was running behind the bulkhead and I was afraid it would break, or rub to ground at some point. Re-reouted and no ground faults there.

I too had an electrical issue on my M7 due to a crushed taillight wire, so I pulled the tank and checked all wire's there. No problems found. Also disconnected the throttle safety as that's caused me headaches in the past.

The grounds for the BD system were shall we say, subpar. I removed two scotchlocks, (Worlds worst invention) and regrounded everything I could find, Including factory ground at lower bulkhead bolt as the nutsert was spinning and twisting the wire. Added ground wire from bulkhead to engine case as well.

Great to know on the EGT. I'll pull a pair off my M7 and see if that makes the 08 go away.

I agree with all of you that the problem will likely be simple (once it's found) and is electrical. As I said about the PV's I anticipate that problem is simply a culprit of the base issue.

Oh, as for the AC computer, I used a external power supply to power it up. Single plug connector into the sled. No workie.

MM- I already was thinking about driving to BD and dropping it off, but I've seen you post many times with helpful info and appreciate your knowledge and willingness to help all. I'll google Salem, Oregon to Preston, and may well road trip this beast up to you early next week. If you have snow to ride, my buddies will come too.

Thanks all.

seen the pv not work from someone using the brake light wire as a power source and the same code from the ETS.

 

[mmsports]

Thanks John

It is so nice to put a face and name to a User name. We got him fixed and he is rock'n

Thanks again John

PS he will see this in about 8 hours when he gets home.

 

[tatorsalad]

That is great what was the problem you guy are pros nice to know.How is the snow back there

 

[mountaincat 800]

Need this back up. What was the cure to this problem?

 

[smoothdawg]

Kevin...post what ya found on this guy's sled. We all want to know.

Kevin...post what ya found on this guy's sled. We all want to know.

yes please post what you guys had to do to make it right.
