ovs M1200 turbo problems

[M1000Mod162]

My brother recently bought a Ovs 1200 turbo and is having nothing but problems! It's set to run 10 lbs with 3076 tial, intercooled. when he first rode it, it was over boosting and cutting out at about half throttle! Would run good under half throttle but wot boost gauge would jump to 17 then cut out and run like sh*t.Took it home and he decided to get a new boost regulator, but decided to take it back up with no boost regulator the next day and it ripped a lot of power! not enough snow to get off trail really so mostly trail riding but got about 40 miles running great at 10lbs boost with a/f reading 12.4 at wot got a mile from the truck and it started to bogging as soon as boost would try and come on! Anyway he loaded it up because he was in a rush to get back to town anyway took it back up Thursday and now it won't even run bog at about 5000 ish and won't rev over 6500! Still pretty fresh to turbos been trying to learn all I can but pretty lost here and we have tried reaching Ovs to see if we could pay them to straighten it out but they seem to be very busy (understandable busy time for them) anyway was just hoping you guys might be able to give some insight for us thanks for any input!

Have you looked at all the boost lines. One pinching or a hole in one. They can blow off the manifold near the secondary injectors. Worth looking. Sounds like secondary injectors not fueling. An 8 would act like that but with no det sensor on the 1000 not sure.

We have had a copuple on our group experience simialr problems and it was the Pure Logic box. Call Travis or Garr...they are very helpful.

I also had similar problem with my cutler 1000 and found it to be a boost leak at the small hose going into my box. Replaced all boost line with good heavy fuel line and super glue.

I have a buddy with a m12t. We were riding last year and he was running his afr at 12.4 and caused enough scarring that his sled was doing the exact same thing yours is doing. would start and run, but no revs.

I never let my AFR reading get to 12.3 for any sustained period of time.

Just a thought.

My 1000 was/is doing the same thing. Happened at the end of last season, ran great, but had a fuel pressure regulator problem. Fixed that, took it out, and it was overcoosting BIG time. It was cutting out on me as well. Took a couple miles down the road before I discovered what was going on, nursed it back to truck, and then has a piston break, and then it wouldn't run very well at all, just as you described.

Anyways, I bet overboosting you detonated it and now have a broken piston. Take the power valves out and look at top of pistons, I had one (different times) break the edge off the top exhaust side, and the other one broke in between the rings.

Rebuilt it over the summer, took boost regular out, and is still doing the same thing. I'm going to have to take mine to OVS and and let them figure it out.

Good luck.

boost signal to box

First thing to check is if pure logic box is sensing boost. When the box senses boost a blue light on the far right will come on, usaully takes 1-1.5 p.s.i of boost. If you get no blue light under boost it will run like you say it is running. If it has no boost to box trace the boost line and make sure no leaks, otherwise problem with box. Good luck.

I would recommend a fresh set of plugs gapped at no more than .025. I run at higher boost levels and no margin if it overfuels and starts to foul plugs. The area spark can pass through the electrode seems to dminish and when under boost flame blows off plug. What I will usually experience is by the end of the day usually on the ride out is I can use less and less throttle. Off of boost will run ok. It is worth a try. Yesterday had same issue in a short amount of ride time first 20 miles. Fresh plugs took care of issue and dropped fuel pressure to 38psi. For some reason it was sitting at 48psi. Just my .02

a bad ground to your fuel controller will kick your butt happened to a friend of mine turbo m1000. he pulled his hair out for several weeks tore the the sled apart made 100 phone calls. we checked the ground at first seemed fine but after weeks of pulling hair and about to give up he took the heat shrink off to find it only had 1 or2 strands were connected. it is now crimped and solidered.and heat shrunk. has ran perfect every since. sometimes it would act like electrical,then it would act like fuel problem, he changed the fuel pump,wire harness, stater, ccu, ecu, had it apart and back together at least 10 times. all to find something that only took 10 min to fix.

Check wastegate to make sure it is working, overboost from wastegate not working will cause overfueling and cutting out. PL box is only good to 17lbs and after that sensor is overlimit. Fueling from regulator is easy to check, see if pressure goes up with boost. If it doesn't or goes down on boost, find out why, weak pump, bad regulator or boost line, etc. good luck. OVS should be of help when they get a chance to get back to you.

we have had a few of these too!!!! sucks to find but real easy to check.

problem solved

Thanks for all the help guys it ended up bein a bad fuel pressure reg
