Good to know , I have only messed with the forge wga I have that does not have that, I have to loosen the nut and adjust it at the end.

 

ok now i have an even better understanding of it...the arm itself gets turned, so theres no need to loosen the locking bolt...right on

Well I checked the dp bolts and they're tight. So that leads me to the waste gate flapper I guess. After reading you guy's post as far as preload I've always adjusted the wga to meet the flapper. So idk, I'm guessing that the flapper sheared. I have a spare turbo to look at but I'm not seeing a way to just replace the flap. Anyone know how? Guess I have to take off the turbo to inspect. I'm not seeing enough room to just remove the O2 housing. The front bolts maybe yes if I remove the radiator but the rear O2 bolts look like it's not even worth it to spend time on. Seems like I should just spend the time unstrapping the turbo. Now I just have to find the will power to do it in this hot humid, wants to rain every day Florida weather.

Edit: before I get into that how likely do you guys think that happened? I did a search and didn't find a single case where that happened. I know I had light preload but you really think that flap wore down?

 

Ouch yea its been hot as fu..

 

So, update. Finally got a chance to do some work last night. After a couple weeks of wondering what was going on I came up with the O2 flapper somehow had sheared or something. As of recently I've heard a ringing and thought yeah, that sounds like the flapper banging.

So last night I pulled of the turbo to check it out. Pulled off the O2 housing and nothing out of the ordinary. I leaned back stumped. The only other thing I can think of is my manifold is cracked. I looked and felt it over and nothing felt odd.

Now, I really don't know what's up. A good piece of news is the turbo is still strong. No shaft play what so ever! So I preloaded the waste gate pretty well and put it back in. It started raining so I'm not done yet but just an ic pipe and fill the radiator back up. Then I'll see how she is. I think though I'll have the same problem.

Ideas? Regular vacuum, preload good, O2 & dp solid. I'm going to do one more scour of the ic pipes.

 

Never mind! Took it to work this morning and back to normal. Whatever I touched over the weekend did it.

While it was off I had the room to put some nice preload on that thing so there's 2 or 3 more pounds in there.

 

Did you fix your issue? How's your tune with the MAP sensor?

 

It was your preload man I would put cold hard cash on that. Mine did the same thing and I thought I had the preload correct. It was only after I pulled the setup off the car and and reset the preload (and in my case re-clocked the turbo) did the noise finally go away

 

Yeah, issue is fixed. Runs better than before. The SD tune is going well the only issue I see is on HOT starts (and I do mean hot like 100 outside, high humidity, been sitting in traffic) she stalls out on starts. But tac it up a bit and get going its fine. Only happened twice so far. Otherwise, perfect. NO complaints.

Yeah, it was weird. But had to be that. I probably had to take it off anyway because with the dual core radiator there's little room to pull a waste gate arm up and all that stuff.

Also today I ordered some Energy Suspension Polyurethane. Gonna be doing my own motor mounts soon. As everyone else with a bigger radiator my waste gate arm is bumping against it. Cant have that and besides the stock mounts are toast.

 

I was too scared to even install my radiator until after I filled my mounts and installed them, way too close for comfort

 

Not much really to update. Boost is still good.

When it's hot and humid, I can sense something is going on with my tune but can't quite put my finger on it. Otherwise SD is fine. Running well, getting rich.

Still haven't filled these mounts yet. I need a solid weekend to pull, fill and cure them and things just haven't worked out dealing with time.

Other than that, the car is done. I really have no desire to modify anything further. I've touched just about everything. Engine, interior, exterior, suspension, brakes. I'm honestly out of things that make me say, I have to do that.

The only other things I'd like are a new front bumper (but I'm not jonesing for it), I'd like to touch the rear but meh, pistons & rods to up the boost (but only if I get a stupid deal on one or the other, then I'd push for the set) and a dohc head (but that put together complete is 1.5k so...)

So, I guess she'll just roll around and enjoy her golden years.

One thing I am curious about is I just fixed my ac and damn is the car really vibratey at a stop. And as far as acceleration goes, really lancer like until boost hits then we're looking at high boost at lower rpms. How do your guys' Lancers run with the ac on?

 

I have been having issues with my SD tune wanting to stall sometimes when downshifting or coming to a complete stop. RPM values will drop down to 500 and sometimes stall. But it only happens here and there. I'm trying to adjust the idle error tables and the ISCV below 500rpm table. Hopefully that fixes my issue. Are you having a similar issue?

 

No, never wanting to stall at a stop or anything. The closest thing is on really hot days on a hot car sitting for about 45 it would start then stall. Only happened twice. I have a clue where to look in my rom but I'm almost always doing other things.
RPMs are normal, no hangs really. Sometimes coasting down a hill the RPMs dip to maybe 500 and bounce. But back on throttle it's back to normal.

 

Being that it's doing it when it's hot, I would start with the primer cranking enrich first pulse, and adjust the range of temp that's giving you problems.
