Default Finally Did It!

Hello guys! So, after so much debating on whether I would do it or not.... I finally did it! Yep, that's right I finally f###ed my car!

Here's what happened.....
Installed a FP Red turbo,
aps inlet (big pita!),
65mm aps cai,
used 850cc injectors,
sti red manifold with tgv deletes and support for side-feed injectors

all of this with the stock intercooler, turboxs catless exhaust, and utec delta em. The car ran sort of good, it did ran much faster and with some lag but it felt great, although at idle the oil pressure oscilated a lot and the rev dropped noticeably to the point that sometimes the car went off.
After the long-waited APS DR525 FMIC arrived and got installed, everything got worse, the car bogs out horribly from 3.8-6.5 rpms; sometimes from too much gas I think, and other times it just doesn't feel right as if the turbo was not acting (controlled by e-boost2 btw set at 15 psi).
Other supporting mods: walbro fuel pump, greddy catch tank, defi gauges (oil p, fuel p, boost, water temp, oil tem, ext temp.), aem wideband 02 sensor and a SMC ALKY kit that we have not enabled yet.
Some notes.... there are no real tuners over here, everything's done on a trial basis and internet. If you have a map we could use I would greatly appreciate it. I think it's just a matter of tuning, the thing is we don't have available anywhere near here. Maybe you have a similar setup that you can give me your fuel and timing map so I can work myself up from there. Also, I have a trouble with the e-boost that is not controlling right my turbo. Set to 40sp1, 35sn1, 3.2gp1. If you work with one and could advice me how to set it right....THANKS

That's what happens when you put a bunch of stuff into your car in a country where you barely have wrenches. Oh well, it's not all lost. Hopefully some good samaritan will help me do some sort of adjustment (mechanical or tune) through here. Thanks

what did you use to tune the car? no mention of any sort of em

i hope you're not relying solely on the e-boost2

it would be difficult to get your car running properly without a tuner who can get his hands on things to tweak things. you could study a lot yourself and learn to tune which might be what you have to do. starting with such a modded setup might be difficult for you though, i'm not sure. regardless, if your car in its current state has never received a proper tune then i wouldnt expect it to run correctly.
have you scaled the delta for your larger injectors? thats the first and most basic step.
also i think if you want to make the most of your setup you will need a 70mm aps intake or other similar 3" maf setup because your current one will most likely get maxed out quickly on your setup.
good luck...

If i were you i'd contact a tuner here in the states and work with him, usually you can send a datalog to a tuner and he can modify your tune and send back the modified map, then load that up and do another log and keep sending it back so the tuner can tweak it, IMO that would be your best bet.. Otherwise it sounds like you're going to end up having to purchase a new engine if you keep flooring it around without a proper tune..

I don't know it the current 32bit ecu is still limited with MAF scaling and reading over 5V
you may need a larger MAF size like 80mm and do some careful rescaling

Using TURBOXS UTEC DELTA for 06 WRX

I'll post some pics in these days, hold on... I wanna prepare it so I will not be mocked that much...

OK guys, really improved the car in the last days. Although, I do have a couple of mishaps that I'm not happy with like....

The car will not sustain it's boost; it will go from 16.7-15.6 and jiggle a lot in that range on WOT. To be honest, I don't feel like it runs more (hell, I might say it runs less) but I guess it's because of the bigger flow it has now with all the piping from the fmic and also that it's too big of a turbo for that misery of psi (17 tops). As to the boost not sustaining itself, I think it might be a setting from the e-boost releasing pressure too easily OR it might be the IWG (which I don't think, since it's too few psi to have problems with). Tell me what do you think.....

The car runs pretty smooth in every transition., although I'm shifting like a grandma because I'm using the weak stock trasnmission (we'll talk to andrew in the future, don't worry)....BUT my friend pointed out that the TPS is not opening to it's full position and only using really small amount of the voltage or something like that (didn't really understand him, just thought I could post it).... Here's a Pull report that you can check and tell me what's up...

an FP Red on a stock wrx block? i don't know how long those internals will hold up to that Red. i'd at least recommend some ARP head studs. upgrade your tranny. that Red will destroy a wrx gearbox. hope you get it running soon. post up some pics and #'s.

Yes, I know... for now we are only boosting until 17 psi because of the stock internals; we'll be changing to cosworth forged pistons and rods along with its bearings, and still I won't go all crazy on boost (I'll say 22-23 tops).

Guys, what I want you to understand is that you have no idea how difficult has been for me to get all that stuff here...Hell, I resume everything just by saying (believe it or not) that my WRX is the only WRX in the whole country.
And that's why I'm begging for help from you guys that have WAY more experience over me.

As to the tranny, I've already broke one set of gears, currently running on a second OEM set (expenses covered by the warranty, no pain there) surprised huh? Well that's at least the only benefit I have from being the only one with a WRX, the dealership simply loves me for tuning one of these things, since it's free publicity for them (with no luck for them though). Talked to andrew today for some ppg's.... that's a WHOLE lot of story... ending in that it will double the price because of my location.

Pics we'll be posting soon, but numbers..... well, all I can give you is billing numbers from the stuff I've bought, cuz that's all I can get from here (no dynos over here).

Something is up with the fuel settings... You're running 12.0 afr with a target of 11.1

As for boost, how is the eboost set up mechanically? What is the boost contorl solenoid setup?

Posting the log so you can read them as columns would help.

Thanks for the info, I'll add some fuel today and post the log so you can check it; as for the E-Boost, we installed it exactly as it says on the manual: Port 1 of the solenoid to Vent, Port 2 to Internal Wastegate Actuator, Port 3 to Boost Pressure Source. Electronically is set in the Boost Group 1 only, with the settings of SP1 (set to 47, which boosts 17 psi), the GP1 (which is the gate pressure setting, is set to 3.2), and the SN1 (which is the sensitivity, is set to 35).

Sorry about the log, I just don't know how to put them to appear as columns, I'll try on the next one. Thanks

yea you definitely need to get that fuel in line... i'd even run lower boost than you have until you figure that out. i'm not sure how target AFR works with your setup but something isnt right there. your IDC is at like 65% max but is way off of your fuel targets and definitely too lean. figure that out first before moving forward with anything else.

This is exactly what I wanted, some guidance. Are you telling just to go to the fuel map and add more fuel? Or to adjust something of the Injectors on the Parameters section? These IDC numbers should be on what? And yes, I would target my AFR on the basic target everyone has, there's no difference on my setup (until I get my alky injection working I guess I'll go a bit leaner, but not until then)

What could possibly be corrected (mechanically-which I know it would be impossible for you to tell me- or on the ecu) so my idle and stand by's at red lights and turns remains steady? At idle, I suffer from a slight oscilation on the revs but most of it on the oil pressure; running with a Defi Oil Pressure Gauge, and really frustrates me when that red warning light comes on along with the annoying beep. Note on the revs is that it now stays on the 730-760 range and I don't remember how it was when stock. Thanks

Sounds like air leaks. Post MAF likely.

Should idle between 500 and 1000, so that sounds fine.

Are you using a wideband O2 sensor to monitor your AFRs? I know you can get a readout in the UTEC logs from the factory narrowband O2, but they are WAY off, only good for getting 14.7 AFR's at a cruise.

Are you the one tuning the car? I assume so, but wanted to make sure. You can re-calibrate your TPS in the UTEC pretty easily, and also you might wanna try using "Speed Density" mode to tune, it makes things alot easier as far as making fuel corrections go.

Most of your problems are probably in the UTEC, your going to have to also make sure the UTEC knows what size injectors your running, and your going to have to scale your MAF differently if your using a big MAF.

Read the entire UTEC Quick-Start guide here:

http://forums.nasioc.com/forums/show....php?t=1221413

And ask any questions you have about getting your car to run properly with the UTEC here:

Good luck! Your a pioneer for your people.

I agree. Especially if installing the FMIC made things worse. Get yourself some t-bolt clamps (if you didn't already) and replace all of your worm gear clamps on the FMIC couplers with those. Then check for boost leaks. There's tons of how-tos on doing it. That'd be my first step. Tuning around boost leaks is gonna get you nowhere fast.

double check all hoses on & around intake
& turbo.

why does your taps 87?
did you calibrate the tps?

I'm so glad you're helping this much, Thanks really, I've tried making different threads and none of them got many replies as this one.

Ok then... the most shameful thing happened to me today... since I'm pretty much the only one with this car in the whole country... It actually made a national car magazine's cover and big writeup in the middle of it; the shameful part was that I really wanted to impress the photographers and staff... and guess what.... my car died! Yep, they actually had to help me to push the car 1/2 a mile back to the garage. All because a stupid t-bolt clamp went loose and distorted my maf.
Really pissed off on a 1500 dollars fmic with sissy clamps, COME ON!
Anyways, spent over 100 dollars just on big guy's clamps and problem fixed (for now at least).

Moving on, I've been fixing some problems I had with the exhaust, as it was hanging too low and I was bumping with everything; so I cut a considerable amount from the vertical part of the downpipe and the joined it with no problems, and the issue was fixed. Although, the muffler obviously now is a bit tucked in.

As to your replies... please do explain how to check on leaks, as I'm really interested on learning this... Have absolutely no idea how to calibrate my tps (will check that on the guide)....for the 02 sensor, I'm using AEM Wideband UEGO, and the utec... I'm really attracted to speed density, and I've read about it on the guide but I simply can't get to work along with everything, so I always end using the same open loop fueling...
Thanks for the pioneer description, I just want to have fun with this car and learn a lot from it and from you guys, also.

As I was working today on the car, I noticed that the oil pan, enine mounts, chassis bridge, and surroundings were filled with an oily-like substance (well, it was really oil)... that immediately freaked me out and I checked above the engine and the only thing that I noticed was the the bolt that screws on the power steering was seriously leaking fluid. Could it be this the whole mess? Could this be causing my oil pressure to fluctuate?

On the fluctuation part, I may want to add that I changed the intake manifold to a wrecked sti red manifold in what I think is in a good condition but I did not changed the gasket and this manifold came with tgv deletes. What should be recommendable to check on this and how? I also notice a slow response on the throttle body, what do you recommend? Thanks

Sorry for the double post....

Ok, I'm not a big fan of the BOV's but I thought I would need one with this setup, so I installed it (APS FMIC BOV); honestly, don't like it at all, it's impossible to set it to the right pressure... hopefully this helps me on the idle issue.
I will also change the throttle body, just to try if there's a difference between the 05 sti's and the 06 wrx's.

Today, I was talking to a friend who has an evo and he saw a rubber pipe of the intercooler that was bent like a bottleneck; he told me that this was making my car run badly. I simply did not mentioned this before since I thought it would not make any issues since the turbo would inflate this... feedback please.
