You need to adjust your WGDC IAT compensation table.

Really? It was something to do with the wgdc and only being able to go up to 30%?

 

I paid 7 bills for the license and then the tuner can't get my car straight bc ecutek won't give him access to all of the tables? That's bs. I should ask Ecutek for a refund.

 

Yes, we are well aware of the WGDC ramping. It showed up in the 2006 LGT first but it was added to the 2005 "updated" roms, 521N and 522N. It was discussed in November 13, 2006. I had actually seen it earlier but I was just a noob and didn't know if I was doing something wrong.

The fix wasn't that easy.

 

merchgod had to patch the rom himself.

 

However, merchgod added an easy to use button to the latest romraider defs to take care of it so we don't have to ask him for the patch anymore.

2005's with the latest dealer flash (either ecu replaced due to fan, or ecu reflashed for stutter or ecu reflashed for cruise control fix) will have the same problem as you had with your 2006.

Yeah. I've been thinking about this. You would need at least a little bit of WGDC to make any difference. If it is fully closed at 0% WGDC, it shouldn't make any difference.

At normal temperatures, I've seen it creep up to about 13 psi in the mid-rpm range but I can't find the chart right now.

Valid, but it shouldn't curve that much; especially on a stock pill.

 

It could be that the actuator is a 16 psi or 17 psi actuator and the reason the boost drops to 15 psi at redline is due to the exhaust pressure pushing the door open. That's usually what I see with MBC controlled turbos. The pressure drops at redline due to the exhaust pressure combining with the actuator pressure to push the door open. That's why a lot of MBC controlled turbos will have a tapered boost whether you want it to or not.

 

Take a look at LBGT's AVO380 with stock restrictor pill at zero percent WGDC. Only look at the blue line. You can see that the actuator is set at 10 psi because at that point the slope changes. The door is starting to open. However, boost keeps creeping all the way up to 13 psi. So, a stock restrictor pill can cause 3 psi of creep at midrange.

That doesn't make any logic...you should have seen 15 across

 

The pill makes it creep upward.

 

Even a stock VF40 with 0% WGDC will not have a flat boost curve.

Is there a Subaru exhaust gasket for a 3 inch exhaust pipe with 2 bolts. This part wouldn't normally be on a LGT. Maybe a STi?

 

I'm looking for a better gasket for the joint between an aftermarket downpipe to aftermarket catback.

SeeeYa, do you have a log with WGDC = 0. IIRC, we talked about checking your boost first with that setting.

Spec_b, I strongly urge you not to swap out your restrictor pill. This is only for tuners. You need to be able to dial in your WGDC if you make a change to the restrictor pill.

 

hey thanks for the chart. I just ordered 22326KA120 which according to cobb's chart is 0.028" but the link's chart shows that pn as a 0.0472. I don't know which one's right so I ordered both, they're only $3 each.

 

What do you mean Cobb's chart. The 22326KA120 is listed in the catalog as a 1.2 mm pill. This is a confirmed size. Notice that the number is not italic. I have it and I can tell you that it is NOT 0.028.

 

but a smaller pill hits higher boost targets, so why'd you go larger?

 

I didn't go larger. The stock 2005-2006 pill is about 1.25 mm. I changed it to 1.0 mm. That means I went to a smaller size. The 2007+ has a different size.

 

The reason to change the pill is to change the WGDC necessary to hit boost target. My target boost hasn't changed at all. I dial in a different WGDC with the different pill size.

 

The reason I went to a smaller pill was that under some situations with all the compensations etc... etc..., I was bumping into the max WGDC. I wanted to lower my WGDC to hit target boost.

 

Is the idea simply to bring boost on earlier in the rpms (i.e. - increasing the boost AUC without increasing peak boost)?

 

Yes, for second gear, I want to hold a much higher WGDC than necessary to hit target boost during spool up. When it hits target boost, the WGDC drops to the necessary WGDC. I needed to lower the WGDC at target boost in order to do this.

I tried tuning my car with a 1.0 mm pill. It works but the WGDC needed to hit target boost is too low for my taste (40 to 50%).

 

For anyone tuning their own car who wants an aggressive stage 2 tune, I recommend a 1.1 to 1.2 mm pill for VF40 2005-2006 cars.

Is this available in Japan as well?

 

Have you asked Paul at AVO? He's in Seattle area now. He probably gets large bulk items shipped every so often. Maybe he can get one thrown in with the next shipment? I know he had some used bumpers shipped over like that.

 

I'm in Seattle area too, so if you can get a reasonable cost down, put me down for one.

$160 is a bargain for such a large OEM cargo tray. Unfortunately, I'm not willing to pay for shipping.

 

I hope a US dealer is willing to step up and start importing these. Seems like a fairly large market since it will fit Outbacks.

Wow. How much was that deep cargo tray?

Spark plugs don't affect AFR.

 

Colder plugs may lead to some incomplete combustion leading to misfires but I haven't seen that in temperatures down to 30F.

I installed the NGK ILFR7H. No difference that I can tell.

Anybody using NGK BKR7EIX? Appears that's what thekingofparts.com is offering for one step colder plugs for the STI/LGT motor...

 

Where did you see that link. IIRC, the BKR7EIX is one step colder WRX plugs. If you could post a link, I could double check.

ummmm....sure...i guess i did....but your intercooler connection is different from mine.I need the part no. for the plastic elbow that connects the intercooler to the VF38

Where are you located?

I just replaced my plugs at 30K. The old plugs' tips were slightly worn. It probably could have gone to 45K.

 

After I replaced them, I got a misfire in cylinder #3. I basically drove on 3 cylinders trying to diagnose the problem. Weird that the car can drive so well on 3 cylinders.

 

I was sure it was the injectors that I had just put in, but it wasn't (I swapped injectors) but still got misfire in cylinder #3.

 

Pulled out the spark plug and coil pack and let the spark plug touch a metal ground while a friend rotated the engine... lots of spark... Didn't know what to do...

 

Then my friend pulled the on the spring inside the coil pack thereby stretching it. Put it back in and the car drives just peachy.

It's not magic. That's just LBGT talking.

 

A smaller pill will help or a 3 port BCS will help. I'm sure you know what I'm talking about.

 

I'm going to try both (smaller pill with 2 port stock BCS and then later 3 port BCS). Just for fun.

For $0.93, I'm going to save myself the trouble of drilling it out.

 

I tune very aggressively for 2nd, 3rd, and 4th gear. Based upon my logs, I think that a smaller pill will help spool in 2nd gear and it might help spool in 3rd gear a tiny bit more.

For those of you who tune your own cars, I thought it would be nice to have a list of P/Ns for different restrictor pills. Cobb lists these values but do not include P/Ns.

 

Thanks to King of Parts for providing the list of part numbers. It was also important as a double check. For example, I thought that the 2006 and 2007 WRX had different pill sizes.

 

If anyone has any updates/corrections/additions, please let me know and I'll add it to the list. If anyone has a list of pill sizes for non-Subaru cars that will work, let me know too.

 

MIG welding tips also work, but for the low cost of a OEM pill, it's easier just to get an OEM one.

 

For all those noobies out there: Don't change your pill size unless you are getting a custom tune.

 

Values in italic are not confirmed.

The open source tuning people are funny - Street Tuner works perfectly fine and it logs just fine too

 

Your load is being calculated differently than the rest of us - it does not take a very large turbo to get calculated loads over 3.

 

 

I didn't say street tuner doesn't work.

 

I just asked why is he logging a lower load.

My load sounds very low compared to the rest of you, what parameters does the ECU use to calculate load?

 

Are you using street tuner to log?

 

I'm not familiar with street tuner logs but I would recommend using the latest version of enginuity to log because it has a LOT of new defs in it.

 

I always log load from the ecu ram. When I calculate load from maf (g/s) and rpm, I get a slight error because of the time differential between reading maf and rpm. However, it doesn't explain 2.54 g vs 3.0 g.
