Essentially what my car will be using is a purposeful hybrid of MAF and SD. Essentially 120 load and below will be MAF, above 120 load all SD baby.


That sounds pretty awesome.

That sounds pretty awesome.

I think so, first time I have been excited about something for the ECU since Tephramods.

In theory SD should clean up the load curve up top too and allow a smoother powerband and possibly more power from smoothing it out. I guess we will see.

Stock injectors, rail and fuel lines off...

Threw on the new MAP, fired right up. HOwever, a very scary noise occured! Like really loud, sounded like heat shield rattle, but then i noticed it echoed through my exhaust so I thought I dropped something into there or in my turbo or something.

Well I spoke with Baka/Jon and the only thing I figured it could be as the motor was running good was wg preload. He agreed, said the flapper was rattling crazy like.

So looking at the wastegate I definitely didn't preload it enough. So I waited for the car/manifold to cool down. And it was a bitch to get the arm back off because the new wastegate is at kind of a funny angle. Finally got it off, but to preload it enough, I just cannot get the damn arm back on the flapper.

So going to attack tomorrow again, maybe after some wheaties, but the turbosmart wastegate doesn't seem to move at all when I pull it like my other wastegates have, beefier i guess.

Anyone possibly have an air pump or something to help get this wastegate open that wants to stop by tomorrow? I don't want to drive it because its so damn loud/rattly right now but I might have to in order to get somewhere with compressed air.

If anyone can help just post up, thanks!

Just got a tip that I can use a can of dust off to help out with this, so going to try that tomorrow. Still if anyone wants, you can join the fun!

Yea, you shouldn't be able to even put the WGA arm back on the flapper arm w/o a compressor, read the directions--there's info on how to set the preload. Basically tighten it up about 2.5 turns from where it slips on easily.

Also, you might have the mounting bracket on backwards--mine was lopsided and I put the short end closest to the engine. I had it on the other way and the wga was not straight if I wanted to get it onto the arm.

Yea I am going to try it again with preload after work.

Do you have the turbosmart one from MAP? It doesn't look like you can put this on backwards to me. The angled bracket also only fits one way and I lined it up the same as the one I took off.

Just trying to figure out what you meant by the lopsided comment to make sure I don't have mine that way.

Makin progress!

[Murlo26]

Well in typical Murlo fashion this became much more difficult than necessary fixing the wastegate lol.

So I picked up some dust off on the way home from work and assumed I could get the hose on my wastegate over the nozzle on the dust off. The nozzle was way bigger! While trying to cram the hose on the nozzle, can slipped from my hands and dropped on concrete floor, cap exploded off, need to go get a new one! damn it.

Now its getting dark and my dumb ass ran over my brand new LED shop light last night, so I didn't have one so I went on a mission to get new shit but it was just after 9pm. So after running into closed places everywhere I found some new tube/hose at Lowe's and a new dust off at target. No shop light as auto stores were closed. Got home got the contraption together and fired and just like hollywood said, extended the arm prefectly! It worked really baller actually lol.

So got it back on and went to put the damn C/E clip on the flapper...dropped :( Spent 45 mins looking for it as I didn't have anything else I could really use. Even jacked the car up to pull the undertray, nothing. Then last ditch effort I grabbed my magnet hoping to get lucky and snag it, nope.

So whatever, need to get a new one of those but had to make sure this fixed the terrible noise. Fired the car up, bam sounded great again :) So not the cleanest thing but I just need a new clip or cotter pin and I am golden again! Stopping by auto store tomorrow to grab a bunch in case I fail some more.

Then back to tuning!

Glad you got the issue fixed.

Why does it feel like someone needs to supervise your wrenching efforts? I kid .. I kid What happened last night sounds comical and should be on youtube.

In all seriousness, the clip is probably sitting on the transfer case or cradle, worst spot ever to try and fish something out.

lol, dust off?
You don't have a small compressor?
