Fórum IW STi Forum

Hello forum, A few weeks ago i started work on the sti. Lots of powder coating, lots of mods and a tune in the spring. Here's the before engine pic and a few teaser pics. Lots to do yet, fuel system, exhaust, intake, etc. 91 tune and then e85 tune. More to come.

Hi! Thanks to all your guys help I think I'm ready to get my car tuned. I'll be getting tuned at simple performance in Utah this Saturday and just want to run down a few things before I go. Here's everything I've done so far on my 2005 STI New spark plugs New intake filter New oil + filter Coolant flush Timing belt +water pump Cyl 4 cooling mod New pcv valve + some dry rotted hoses New boost controller lines New rubber hoses on the fuel rail under intake New coolant crossover pipe o rings... Pre tune checklist!

Hi everybody, I'm reaching out here for some feedback on my vehicle's fuel trims. The car runs amazingly well, but I'm seeing numbers outside the standard range I read about online. The car is a 2018 STI with a Cobb intake and a PRE-fuel damper delete. The vehicle has been dyno-tuned. A common theme is negative trims around 2300 to 2900 rpms while cruising. Any help is appreciated!

What started as off as a trade for my 300zx turbo, now has evolved into me being the owner of THREE Subarus!! Gents, I need to do some cleanup. But before I get to the cleanup part, I need some clarity and advice on how to proceed, relating moreso with the latest and newest arrival. My 04 WRX ej207 swapped STi Nice list of modifications, I blame my 207 swapped wagon for getting me into this mess...and partially my EVO. More to come on that in a bit. But... How did I get here? I own 3 subaru's now...wtf

I've been working on getting this car since April. It's been one issue after another trying to get our schedules to line up among a few other things but I finally got her yesterday! I've been out of the game for over 10 years and I swore I'd find a way back in. I'm in NE GA and she was way down near the Gulf in FL. I couldn't ever find anything in as good as shape, closer. She's got some higher mileage but has really good maintenance records and she is a blast to drive. The previous owner... I'm finally official!!!

Is there a quick and easy way that all you experts out there know of to disable the daytime running lights on a 2010 STi? There’s gotta be a fuse or relay or something that will disable them without affecting any other crucial features, right?

I am wanting to add some gauges or inputs that would be recognizable by the Cobb AP to aid in etuning, or at the very least some gauges that would help in the tuning process (ie. EGT, wide band AFR, IAT, etc) is there a way to make the AFR that shows on the access port run on a better wideband sensor to improve its speed/accuracy? I’m planning an oil pressure, boost/vac, but I’m on the fence for what else. I wanted the iwire AEM setup that could be logged in the AP, but apparently that’s not... Gauges and inputs for APv3

I’ve had my IAG AOS on my car since April. I had read about the PVC that comes with the street version being crap. And it is. So I ordered the VVT PCV for turbo applications. It’s a nice billet unit but has a synthetic ball in it. At any rate, I installed it instead of the IAG valve. Install went perfectly. I also installed the 3MI oil return line. This line “Y’s” into the turbo return line which gives you another 3-4” of fall on the line. It’s a major pain in the ass to install but well... Hey IAG AOS owners!!
