Well your WGDC looks normal for an EBCS setup, but are you running an EBCS? If you're running the OEM BCS, then your WGDC might be too low. Do you see the WGDC maxing out during spool up in your logs?

Thanks for the input guys.

My tuner asked me to check all my intercooler pipe connections..

Could it be my HKS SSQV BOV? My piping are all tightened with T-Bolts..

Should I be concerned about the stock throttle body hose?

Just received my Revision 4 tune, I'll try to datalog soon.

I like this thread. Out of curiosity and I think I will bite too.

2002 WRX Wagon
EJ205 Block and Heads
09 OEM STI Top Mount
GTX2867r w/ internal gate @ 12.5psi
ID1000 injectors and DW300 pump
COBB 3 port ECBS
COBB 3" turbo back exhaust with cat
Grimmspeed ceramic coated pipes on ported stock manifolds

Stock 5MT and tire size. Around 450 lbs of gear and occupants.
91 Octane Pump Fuel @ 8000' elevation in 3rd gear.
11.4 Target AFR
~17 Psi Target Boost
Cobb AP logging, but I did not log the MAF voltage (sorry)

I recently started on a new map to fix a few things that had been bugging me and rescale to a bit higher load resolution.

I started with reduced timing at higher loads and took this log:

https://drive.google.com/file/d/0B_t...ew?usp=sharing

Then I rescaled a bit and reduced the timing just a touch more before taking this one:

https://drive.google.com/file/d/0B_t...ew?usp=sharing

Seems ok to me so far but I am just a self-taught jackass with a laptop. I am open to suggestion lol but I was going to add some more timing back in up top bit by bit and call it good. What do you think?

You're getting some knock from 4400-6000 rpm. This looks like a result of adding additional boost (~20 psi now). Timing looks OK but can be smoothed out a bit, still a tiny bit wavy.

Edit: actually timing at peak torque can also stand to be dropped by 1-1.5* if he wants to try for 20 psi. (Forgot you had an 08 WRX, kept thinking it was a 2L)

I personally think to push 20 psi on 91 octane, the AFR near spoolup and peak torque should be a bit lower, ie 10.8-10.7. It looks like he's targeting 11 now.

The other option is to lower boost back to 18 psi and target 11:1 AFR.

Happy to see that this thread is becoming a positive exchange of information and assistance. If interested, here's my log with VD plot. I took this this morning and when I log with my AP, for some reason the connection cuts out in the middle of the run. Anyway, as you can see, even though I didn't log AFR, I know I'm running lean since I've logged it plenty of times. You can also tell I'm beyond my limit with fueling as the IDCs are at 111% and this is at only 5300rpm.

So am I brother, so am I.

You are logging many parameters unnecessary to log making it hard to decipher but not a big deal. You'll just get better resolution only logging what you really need to know. That being said, I like the timing low where it's at since you are on 91 and high elevation. You can add timing up to the knock threshold but it's good to play it safe. Have you logged AFRs using a WB02? If not, you need to. Nevertheless, you don't have knock so that's good. You might be able to run more boost with that turbo, but you don't want to overwork it unnecessarily at that elevation. You'd have to look at the compressor map to determine if it would be worthwhile. Otherwise, not too bad of a plot at all with the 2.0 at such a high elevation. I'm not sure what the correction factor would be for sea level since I am not at such an altitude. You have plenty of injector left. You could safely run E85. Is that a consideration?

I'm really surprised you're maxing out 1100cc injectors at that power level. Even with E85, I feel like you should have a lot of room left. I'm wondering if your fuel pump is not flowing enough, have you logged fuel pump duty cycle at WOT?

What's your AFR at full spool and redline?

That boost dip is really bugging me. Any idea from your tuner with that one? You are getting more power, but I understand he's still smoothing it out so there's still a little ways to go.

+1 that and the bumpy afr =/

Can you also log WGDC and boost error next time?

Oh it's definitely the fuel pump. Haven't logged it lately, but the next step is to hardwire a Walbro 450. AFR at full spool starts at about 10.5-11 but rises to high 12s to redline. For the winter, I need to turn the boost down to keep things safe.

That's scary!

hmm...I would think a 245lph pump would be able to do better than that at that power range.

On E85, the 245 is beyond it's limit. I've seen it with others and their Walbro 255s. I wish I didn't have to change it out because it's been on the vehicle for 40k miles with zero problems. Maybe I'm just exhausting it after all this time and it's not runnng at full capacity???

I'm really looking to run 12 to maybe 12.5 afrs on E85. The high 12s afr is scary, but E85 is forgiving. Definitely not as scary as it was when I had some hack tuner working on this thing running 93 and 13AFRs. That's one reason he got fired and I started tweaking myself.

Oh yeah, you're on E85. I kept thinking you were on pump 93 and was like "why would you keep doing WOT pulls knowing you're running that lean" XD

Do you have a fuel pressure gauge? I feel like it could be the pump having issues. I haven't seen much data on the 245 sized pumps but the hardwired DW65c with ID1000 is around 80% IDC on E85 with a GT3071 sized turbo at 28 psi, so I'd think the 245 would be a bit higher but not tapped out especially since you're only at 23-24 psi and on a smaller turbo.

I've also seen DW65s run lean as they start to have issues, which showed up as fuel pressure dropping at WOT and the car running lean. But anyway, you're going much bigger now so that's just more for reference.

I'll log fuel pressure and duty cycle. I don't have a gauge but that's a good suggestion. Maybe that is the issue. The 3071 is just a little bigger than this turbo (52 to 50lb/min. Iirc) so you'd think the results between the 2 would be a wash. Thanks for the info.

Yes I watch the AF via Wideband o2 I just don't have it setup to log.

I do have the ability to run E85 but I cannot get it locally. I have about a 2 hour drive to get it so I typically just run pump gasoline. I run around 21 psi and a little more timing on E85 when I do run it but usually only for track days and rally cross events.

I can get 110 race gas a few minutes from my house lol. Just too damn expensive.

Most use around 1.15 correction factor in Denver but I am a bit higher so take it for what you will.

Thanks for the input

I've emailed and showed him the dyno graph. Asked him about the dip in boost in the higher rpm. I'll let you guys know when he get back to me.

Ordered a Mishimoto throttle body hose.. Hopefully that would take care of the boost leak!
