Twisted Turbo M1000 PROBLEMS - Please help

[Slimbo]

pointless thread apparently.

Are you hitting the rev limiter

Is your control box sensing boost?

What issues are you having with the boost controller. I ran 9# on straight AV gas for two years between 4000-8000ft.

Is it going lean when it cuts out, could have a boost reference issue. Also if you are running the stock y-pipe they are very pron to cracking on the m1000's. Look it over closely. Make sure your exhaust donuts are in very good shape.

First thing I would do is turn the boost down and see what happens. We had a M1000 that had some weird issues, ended up replacing the stator even though it tested fine and it fixed the issue.

I sure seems like its going lean on boost to me.

yes another friend mentioned maybe it was the stator as well. But it does seem strange. I am leaning more towards leaning at boost as well since it was pushing the plugs out even know it was running rich where i would really look at it. Im going to try and eliminate as much boost as i can today to cancel that out. Then looking into the stator might be an idea. Only thing is i never had this issue before i put the turbo on, and i dont even have a headlight on my machine now so the draw shouldnt be as much i dont think?

i talked to neil just now and before i do a test run today im going to richin it up some more from 7200-9000 rpm and see where that gets me. then turn the boost right down. hopefully this will help get it on the right track.

No codes from ecu on speedo from over rev

Could it be running out of fuel?

Sounds like a boost leak, bad donut, or bad reed. Did you check the air box connection to the throttle bodies? Have you checked the reeds? Bad reeds are notorious for making a turbo sled symptomatic from what you have described.

Did you check the plugs?

with that mixture of fuel, turn boost down

to about 8 or 9 lbs. and see if the problem is still there, if it is it could possibly be the fuel controller has a glich, send it back and have them bench test it.

Could it be running out of fuel?

I agree with hardass, sounds like fuel starvation when on boost,when you get on it with 4 gal or less in the tank the fuel moves to the rear of the tank and the smart valve directly beneath the fuel pump will suck air, may not be your problem but i would definitely check it out.

I would lean towards detonation beings you said your plugs are backing out. Detonation and rich are different. Detonation is the fuel is being ignited premature or lit in an advanced mode. A reference would be a performance car at full throttle and advance distributor. i ride between 5-7k and use sunoco 112 and limit boost to 12-13. Or sunoco 116 to run up to 20.

its doing this on a full tank of fuel fellas. This is a brand new build. I checked everything, all clamps, pistons, rings, gapped the plugs (which were burning nice and brown btw) I have stock reeds doubled up and brand new. Didnt check them but im sure they are fine since i barely ran it at all.

Neil from Boost-it confirmed with his engineer that the new programming is running normal. which i can confirm because my buddies sled was running the same updated box and had no issues.

ive had two guys tell me stator now... But that being said i still dont know why it would be detonating being rich. I really gotta see if this fuel pressure is dropping off right before i kiss the gauge.

I also have to confirm with someone to make sure my wastegate preload is set properly as its seeming tricky to get the boost down. Ive been told a stiff waste gate can cause this as well.

So its looking like Detonation from low octane caused by too much boost, or fuel starvation from stator kicking out. Or, perhaps its a bad box, not impossible by any means. Thanks again for all the info. Its gotta be one of these things. i hope

The detination he had was because of a bad fuse,or to be exact a fuse not installed properly.When the fuse didn't make a connection the extra injectors lost power.
I don't know why you are on here talking nonsense when you know exactly what happened.

 

[Vi-PEC Powersports]

A fuse which i found and fixed. I didnt realize thats why it was detonating. But it STILL doesn't run properly. Gee thanks Dave, here i thought i was just uneducated but im clearly just stupid. I guess that's why i'm asking for help because i know exactly whats going on. Here i thought this was my first turbo ever. But trying to learn is nonsense. Thank you for your help, i think i've had about enough of it. Im going to get info from people that dont talk to me like im an idiot.

had time to read your post before you edited ......you seem angry. take it back to neil or dave, i am sure they will endorse/fix their work like always. a lot of times, your afr will read rich when in fact it is lean......take the sled back to a professional and he will fix it for you, being a newbie on a turbo setup, you can search for months what's going on, get help from a professional/reputable shop( i am sure neil or dave will help you out.
