Default Outback Sport VF37 EJ207 Version 8 Dyno @EFI Logics

Car: 2004 Subaru Impreza Outback Sport
Owner: Jordan
Tuner: Chris from EFI Logics
Dyno Info: Mustang
Peak HP at RPM: @ 6700rpm
Peak Torque at RPM: @ 6200rpm
Baseline hp/tq for a stock on same dyno: 125whp
Target Boost: 17psi
Target AFR: unknown
Fuel: Sunoco Sunoco 93 pump
Method: Open Source

What's up everyone. So I posted a little early but I'm getting my 2004 outback sport dynoed and tuned from chris s-k at EFI Logics via open source tomorrow (2/6/10) I will post the results ASAP when I get home from the tune. But in the mean time if people would like to make some estimates on what ill make I would sure like some more ideas on expected power goals.

Mods are...
-20,000km 2004 version 8 JDM STi EJ207
-Twin Scroll VF37 Turbo/manifold/uppipe
-Walbro 255lb/hr
-Invidia N1 Race catback
-Custom Bellmouth Twin scroll catless downpipe
-AMS Oil Synthetic 5w-30
-NGK Irridium 1 step Colder

And I think that's about it...
EFI logics is a mustang dyno. And I am thinking 22psi with 93oct pump gas.

Thanks all and stay tuned!

So long story short my car wasnt tuned today because of some boost issues that arose during this baseline run. We were getting full boost of wastegate pressure(10ish psi) around 5,000 RPM and just overall a bunch of issues so back to have some troubleshooting done and find out the issue.

Currently the turbo is 110% good because we un plugged the wastegate at hit 25psi around 2,500RPM. Then checked the restrictor pill, vacume lines, wastegate actuator, ect.

I will keep you all posted as when I get my real tune when the issue is resolved hopefully this week.

sounds like the restrictor pill is on the wrong side of the T. Try swaping them between the compressor and the wastegate

No, it's not. The car was having boost control issues outside of anything mechanical. The person who did the swap is going to be investigating the harness. I was there.

Ya, were gonna do a full diagnosis this week and look into everything. I don't think its gonna be having to do with the merge though because the oem controler is getting power and there isn't to much other wiring that could result in the issue... I hope! Eakkkkk :-(

Actuator CHECK, Turbo CHECK, Solenoid CHECK,

Next prolly gonna go into buying a known good restrictor pill and leak test all of the vacume lines. So ill keep ya posted!

That's a possibility... I want to speak with my tuner and mechanic before I were to do so because if they perform more similar to an oem set-up that the mbc that my tuner hates to use then that is an option. But... I still need to diagnose and troubleshoot the reason behind these results.

I know this isn't the place and I can "search" but what is the best bang for the buck EBC?

edit after reading it says base line, do you have graphs of the final?

That looks pretty good for such low boost.
Thing will wake up with 20+ psi also.

Ya, no final tune. The sheet provided was at 13.70 psi and my base map I've been driving around.

But yes, I will update of course when I take care of the boost issue and get tuned hopefully in the next week or 2 I'm shooting for.

i have noticed on mine that even with a boost controler, and 18psi IWG actuator i start getting an uncontrolable flutter above 20, as of right now i am just staying with 18psi because my clutch is gone, but and decent EBCS will fix your problem right up looks good so far though

The process to test the OP's issue was as follows..

- Installed USDM WRX restrictor Pill in stock location
- Installed working OEM solenoid to test
- Swapped hoses on the solenoid
- Tested wastegate actuator
- Checked hoses to intercooler
- Set max duty cycles in all WG tables in ECU, verified AVCS functionality ECU commanded exact duty cycle, AVCS executed to commanded values in calibration file
- Removed the line to the wastegate to test the turbo Turbo spiked to 20psi in a momentary WOT blurp.

At this point we are under the assumption there is a wiring issue with the car, the original place that did the swap is investigating, and we are working with them to rectify the issue.

Thanks,

Chris

Is the 13.7 psi the stock boost level? I know you are having an issue, but what is stock boost level on a v7 or v8?

I've heard 18psi. I just got done with my v7 swap, but I transferred over the manual boost controller I had, and it is set at 14psi.

Wondering if it will go to 18 controlled by the ECU if I put the stock BCS back on.

Nice power for such low boost!

Thank you Chris and all the guys over at EFI Logics for the help on trying to target the issue. I will be in touch as we find out the issue

It was target to be at the OEM JDM STi level of 17psi but only hit 13.7.(17 is stock jdm sti vs 14.5 being stock usdm sti)

And I am trying to stay away from a manual boost controler at all costs... but if there isnt a choice and we have to go that route then I will most likely go with a aftermarket EBC

why no manual boost controller?
