How would you determine that with AF Correction changing so much? Average number?

Maybe this will..

Boost looks fine. There's no wideband, so can't say if the fueling is ok.

Yes, running E85 in it right now.

It basically involves plotting total fuel trim (AF corr + AF Learning) vs MafV/s under conditions where Mafv/s is mostly steady, i.e <0.2 v/s and when IATs are not under heat soaked conditions. Once you plot it via scatter plot, you can look at where the average values are for the fuel corrections for each MafV value. You would then apply the correction to the MAF table. This is basically closed loop maf scaling.

So the steady mafv/s logging would need to be in the 'c' range?

For speed density would this be total fuel trim vs map?

Looking like some knock on peak torque. I'd add more fuel and take out a degree of timing because you're pretty lean IMO for stock headers and a stock sti TMIC. When you get the 1000's aim for 11.0-11.2 if you're tuning on the street. Also try and go 3 port boost control solenoid. Yeah it is a bit more work but in the end it will be worth it. Hopfully ShinjiML will comment because the guy knows his stuff.

I agree with Delphi about the fueling being a bit lean, I'd drop the wot range from peak boost to redline by 0.5 AFR for now. As for the knock event. Do you have any other wot logs? Look for consistency, because with your built motor, it could very well be noise. Your settings look fairly safe for 93 octane, so in the absence of anything mechanical, it shouldn't be knocking. But cars respond differently, so looking for consistency will help you determine if it's real knock or just noise.

If you don't have any other logs, try pulling 2* at peak torque and doing more pulls to see if it continues to knock. If it does, try adding 1* to your current timing and see if it changes.

NEW LOG

Brought the tune back up to almost 20psi to see whats going on with the AFR and finally after fixing many things and many people telling me 565cc injectors arent enough. I think I finally see my injectors maxing out at 85 IDC.

I dont understand how IDC works but as the RPMS go up IDC gets stuck around 85 while the A/F rises. Putting my 1000s in this weekend and getting a retune. Hope to make a little more power than these 565s but who knows.

I really appreciate the help from both of you guys. Definitely seems like the knock is very random and shows up every once in a while in the logs, that knock I usually ignore and happens once every 20 or so logs.

Do you guys think its possible to just barely be maxing out the 565s on this Blouch 20g with 3071r center? Is there a chance I could get away with 24psi?

I'm running the MBC to help a bit with the lag as im on a 2.0 and it isnt very spool friendly. Full boost around 4k with almost 0 power below that definitely makes every last bit worth it.

There's no way you can get away with 24 psi on that turbo running only 565s without heavy water/meth injection. The leaning out is probably due to you running out of fuel.

Assuming your maf scaling and fueling targets are setup correctly and no vac leaks are present, a possible reason for your injectors being stuck at 85% IDC could be due to the fuel pump running out of flow, which would also explain the leaning out.

Edit: by running out of flow, I mean it's on it's way out, with the flow now so low that it can only hit 85% IDC on 565s.

Edit 2: can you add fueling final to your logs?

I was referencing 24psi after the dw300 and id1000s are in this weekend. Most likely going with Eric from torqued performance for an etune until I make my way to PSI Proformance for a protune. I definitely see the leaning out. Ill add fueling final to my next log.

Im not sure which fuel pump is in there but it seems in my past logs (although not on the same tune) and could be stock. I do know the fuel pressure is good all the way to 20 psi a few months back. Maybe being a stock one pushed to its limits puts some extra wear on it into failing. The dw300 should fuel my needs though. Would you suggest an aftermarket fpr?

I had a walbro 255 in there. Installed the ID1000s and dw300.

In the process of E-Tuning and im very surprised how fast its coming. Im sure there is a bit of work to do.

Boost is up to 20psi and car is running great. Are there any mods I should look into to help the car? Could anyone estimate my power levels? Virtual Dyno says 350 but im guessing its more 300? Is there more room for power or is it at the top of my cars ability with the supporting mods? Thanks for all the help again.

Log looks good, I'm sure your tuner will be smoothing things out a bit as you continue the process. Powerwise, 350 whp on VD with dynojet settings seem reasonable considering your turbo and tune settings. Looking at the current settings, you should still be able to safely get some additional power out of it.

Hi guys,

New to all of this and just took my first data logs with a Cobb APv3. I have a 2018 base WRX that is stock except for Thule roof rack (haven't adjusted tune for that yet ). I'm running Cobb Stage 1 93 octane OTS map.

Did two WOT pulls in 3rd from about 2,500 RPM to around 6k. I think I get the general idea of what to look for, but would appreciate any feedback. Thanks!

Hello all
2018 WRX - turboback , EBCS, TGV delete - Stage 2 93 etune
looking for some advice/feedback.... just installed the EBCS and did the deletes a couple of weeks ago and am currently on rev5 of my new map, but been worried lately that I might have a possible boost leak. a couple of reasons I suspect this.....
-the boost doesn't seem to hold up there very long and seems to drop more than I would expect through the pull
-I definitely feel like the sound I'm hearing is more of an actual whistle than the turbo spooling sound that I'm used to.

If you guys could take a look at my log and let me know what you think....I would greatly appreciate some feedback.

3rd gear WOT 2500-6500 pull log .....
