Plumber's son has a DSM that's falling on it's face.
 

Plumber's son came up to me today, and said he just got a 99' Eclipse w/ a "big garrett turbo" he claimed that falls on it's face at about 4k rpms. He bought the car already "done up". He's suppose to stop by in a bit, I told him i'd look at it today after work, I figured it was getting too much boost for the fuel to compensate for. Probably is a nonturbo motor, w/ non turbo fuel system, and non turbo ecu. not sure yet, i'm hoping the wastegate is either stuck open or the boost controller is turned the wrong way. Sounds to me like he's bought some kids ---- up of a project, but we'll see.

is there a point to this or??? O0

Re: Plumber's son has a DSM that's falling on it's face.
 

lol, yeah point is don't go bragging to people you work on cars or they'll drop them off at your house and make them your problem.

Re: Plumber's son has a DSM that's falling on it's face.
 

He came by, the car has a widebody kit all molded into about a 7k dollar paintjob. candy apple red... looks like a showcar, but the damn thing cut out at 4k at full throttle.. checked the boost controller, turned it all the way down.. went for a drive.. still same problem.. doesn't fall on its face completely, just cuts out like sputters. not sure what it is, I told him he might have too big of a turbo on it for the fuel system. Or the wastegate could be bad ???

Re: Plumber's son has a DSM that's falling on it's face.
 

Tell him to take it to someone who know's what the ---- they are talking about...

Re: Plumber's son has a DSM that's falling on it's face.
 

Lol I did. I sent him to the local old ass import grease monkey. That'll do alot of good.

Re: Plumber's son has a DSM that's falling on it's face.
 

as long as it is a turbo ecu, etc fuel compinsation at 4psi should be no problem at all for a dsm

i was running 22psi on a completely stock fuel system for over 5 months

FIXED

Check the gap on the plugs.

Re: Plumber's son has a DSM that's falling on it's face.
 

IT'S A ------- BOOST LEAK! DSM'S HAVE A ------- MASS AIR SENSOR. I GUARANTEE YOU THAT'S WHAT IT IS! THEY GET THEM ALL THE DAMN TIME. CHECK ALL THE COUPLERS. THE BEST THING TO DO WOULD BE A BOOST LEAK TEST. FORCE SOME AIR INTO THE COMPRESSOR OUTLET PIPE AND LISTEN! YOU'LL BE SURPRISED.

Re: Plumber's son has a DSM that's falling on it's face.
 

Cuts out at 4k rpm but what's the boost pressure doing? What's it hitting and is it dropping when it cuts out, etc. RPM doesn't mean much, it's about load/air flow.

oh boy, you know its bad when Buk invades your thread. :1

Re: Plumber's son has a DSM that's falling on it's face.
 

damn i opened this thread too quickly, thought there was gonna video of a dsm falling on some guys face :(

Re: Plumber's son has a DSM that's falling on it's face.
 

is it like a fuel cut? Pop pop pop?

My buddies dsm does that only because its boosting too high and the ecu is cuttin the fuel. lol.

Re: Plumber's son has a DSM that's falling on it's face.
 

yeah it kind of feels like a fuel cut.. but i turned his boost all the way down, and its still doing it. So i'm thinking it's either a boost leak, or might need a new coil

Re: Plumber's son has a DSM that's falling on it's face.
 

at a boy throw some parts at it.

Re: Plumber's son has a DSM that's falling on it's face.
 

So....what boost are you seeing? You never responded to my last post, to busy trash talking I guess. 3 psi? 10 psi? 20 psi? Makes a difference, if you have a boost leak you should see it.

Re: Plumber's son has a DSM that's falling on it's face.
 

A boost leak in a DSM isn't like a boost leak in a speed density / MAP sensor car where you just don't make as much boost. It's unmetered air and really fucks with the mixture a lot (pig rich). It'll feel like it's hitting fuel cut or if it's bad enough won't even rev out. I swear to God it's a boost leak, so boost leak test your damn car and you'll find your problem.

Re: Plumber's son has a DSM that's falling on it's face.
 

Is the bov recirced?

Recirc it and see if the car runs better.

The factory computer doesn't like it when the bov vents to the atmosphere.....

We really need to know what the psi is at.

What has been done for the fuel system?

We dont know ---- enough to really help you. Dont spend any money until you find the problem.

Re: Plumber's son has a DSM that's falling on it's face.
 

Jesus Christ man, stop posting retarded ---- about DSM's. Venting your BOV won't cause the symptoms he's having, especially under any sort of load. A vented BOV on a mass air sensor only causes small driveability issues during idle and shifts. That's why it falls on its face when you put the clutch in or shoots flames when you shift. It's a ------- boost leak you goddamn retards.

Re: Plumber's son has a DSM that's falling on it's face.
 

i bet boost leak or fuel cut ask me how i know?

i have 2 SITTING in my drive as we speak, god i hate them but its another ------- addiction. has he even said if this was a 4g or a 420a?

Re: Plumber's son has a DSM that's falling on it's face.
 

Either a boost leak or an issue with the MAF itself (or wiring to the maf), I've seen that happen before too.

If it's a stock boosted 420a more than likely the stock maf is being maxed to ---- and the ecu's going nuts. It's really hard to give you ideas when we don't even know what motor/ecu setup it is.

Re: Plumber's son has a DSM that's falling on it's face.
 

I take it the guy spent all that money in engine performance and a paint job, but didn't bother to pick himself up a wideband?

I know what you're talking about, I'm going with a fuel/ecu related problem on this one.

Re: Plumber's son has a DSM that's falling on it's face.
 

Its easier to get the vain girls in the car (to rape them) with a cool paint job than with a ricer fly-by. Thats why so many loosers have ricer wings, body kits, and 24" rims. :y

If our car guy had any clue, he'd have pulled the plugs each time to see what was going on. A wideband isn't needed for diagnosing an extreme fuel problem (pig rich/super lean).
