Description At iaTUNING we have a passion for personalizing vehicles, and have since our doors opened in 2003. Over the decades we’ve seen the modification world, which includes tu ning, evolve considerably since it’s ‘Wild West’ days. More recently, terms such as CARB EO, and Green Speed have been thrown around the internet, which often led to further confusion, speculation, and uncertainty. For 5+ years, Cobb Tuning has worked tirelessly on Project Green Speed. Through their program, certified Cobb ProTuners now have access to a vast library of CARB EO certified parts and ECU maps. These are the very same maps that iaTUNING implements as their baseline, which are referenced as version 4.0 and higher. As one might deduce, iaTUNING’s beliefs and business practices aim to support Cobb Tuning’s on-going efforts of the ever-evolving automotive industry. Environmental Protection Agencyback*Note*In alignment with Cobb, our company requires all vehicles, USA and non-USA, be equipped with the following factory Subaru parts, in good working order: Downpipe. This requirement could change in the future pending the CARB EO submission process of Cobb’s GESI cat equipped downpipes.

How the E-Tune Process Works for Accessport and Open Source 1. Speed Density Yes or NoIf the vehicle has a standard intake setup with the Mass Air Flow (MAF) meter, then select NO. If you desire a tune that includes Speed Density support, whether it be full SD (no MAF), or Hybrid MAF w/ SD, then select YES from the drop down menu during purchase. If you are uncertain which setup you have then feel free to send us an email or call to verify. The majority of cars we tune will answer NO to this option. 2. PurchaseFor online orders, fill out and include the following details in the 'Special Instructions' section (found in the shopping 'Cart' not on the 'Checkout Page'). Make:Model:Year:Miles on Motor:Miles on Odometer:Transmission: 5MT, 6MT, or ATFuel Type: 91, 92, 93, 94, e85, ETC.Software: Accessport v2 , v3, or Open Source?Modifications: Include brand and size when applicable. Example: Cobb 1050x CC Injectors. 3. Testing and Data LoggingWith the client's provided vehicle information, we will send the 1st map as well as detailed instructions for testing and data logging (with AP or Romraider). The 3 most common tests the vehicle will undergo are: Idle Test = Vehicle sits stationary and idles at 3 different RPM targets for 2-3 minutes. Driving test = Vehicle is driven in normal circumstances for 3-5 minutes in stop and go type traffic Wide Open Throttle (WOT) = The vehicle will need to achieve full throttle in a pre-determined gear and pre-determined RPM zone (included in the instructions). This will require a bit of space to perform the tests safely (closed circuit track always recommended) as maximum speeds can range from 60-90 MPH. The peak speed is different for each car based on gearing and tune desires. 4. Review Data LogsAfter the data log files are received, we will begin the review process. Additional adjustments to the ECU will be made based on the data log review process. The revised map will then be sent back by email. 5. CompletionWe will repeat Steps 3 and 4 until a final map is generated. On average, a finalized map is reached between 5-8 attempts. Now keep in mind, we're not here to hurry along the tune process. If the tuning process takes more than 5 revisions, then so be it. Our goal is to achieve a well rounded tune with an overall positive experience. Based on our tuning history, our first map is almost always guaranteed to start and run the engine. There is of course the exception where mechanical or electrical gremlins exist. Map Credits Explained 1st Tuning Credit is valid for 60 days from date of purchase and is for only 1 fuel type. During the 60 days, the car must maintain the same owner, modifications, and fuel type. If a client were to install a larger turbo at day 30 then their initial tuning credit would expire and a new Repeat Client credit would need to be purchased. After the purchase of the 1st turning credit, all future credits are offered at a discounted rate for the lifetime the original credit purchaser owns the vehicle. This offer is non transferrable to new owners, nor new vehicles. Example: Client John Q completes an e-tune in 2016 and wishes to upgrade his fuel system (injectors) in 2020. They would purchase the discounted Repeat Tune Credit and a new 60 day tuning period will begin. Alternations to the modification list, while in the middle of the tuning process, will require the purchase of a Repeat Clients tuning credit unless pre-authorization is received from our Tuner, Stephen Clark. A Break-in Tune is considered a separate credit from a Performance Tune credit and is used to tune an engine with brand new internals (pistons, cams, ETC). The Break-in tune has extensive focus on the drivability segment of the tune and foregoes any full throttle testing. FLEX Fuel tunes require a total of 2 credits. The 2nd credit would be purchased at the Repeat Client rate and could be purchased during or just after the 1st fuel type is tuned. Do not edit the modifications between the fuel types or this will require going back and redoing the original 1st fuel type map, which would increase costs. For vehicle safety and intellectual property reasons, Accessport maps may only be opened by our in-house Certified ProTuner. Also referred to as Locked. This is a zero exception policy. Tuning Background Our experience stems past the Dyno and includes world-renowned race track testing. We are one of the few USA based Tuners to physically travel to, and tune on, highly regarded tracks such as Nurburgring and Hockenheimring. Beyond race tracks, our E-Tune program has spanned the World to Australia, UAE, Alaska, Africa, Europe, South America, and beyond. Despite the distance, we continue to treat every customer with what matters most, respect. When the time comes, consider iA-Performance for your Subaru tuning needs. Don't forget to click on the various tabs to read more about additional tuning items; Emissions, Trouble Shooting, Supported Parts, & Videos. Emissions So why is the modification industry changing? After ~2018, long-standing emission regulations of the Clean Air Act started to receive enforcement by the Environmental Protection Agency (EPA). With that said, modifications for street driven vehicles must meet the EPA's standards in order to be considered legal for use. Thankfully, several innovative companies have undergone the arduous task of obtaining EPA compliance status for various aftermarket parts, including ECU maps. Although we are no experts on the matter, and far from being attorneys ourselves, it is safe to say that California holds the highest standards for emission controls, even higher than the EPA. Items which achieve the California Air Resource Board (CARB) approval are distinguished with an Executive Order (EO). The EPA then considers a CARB EO listed part as legal for use on a street vehicle across all 50 States. Thankfully for the tuning community, Subaru specifically, Cobb Tuning has an ever-growing list of EO listed parts, including Accessports and the very tuning maps which we use as our tuning foundation (version 4.0+). For a full list of Cobb EO listed parts, please visit the following link here. Following a likeminded approach, all street driven vehicles tuned by iaTUNING must retain factory functioning emission control parts, the most common of which are: Downpipe, TGVs, air pumps, and EVAP purge components. Trouble Shooting Our highly skilled Cobb Certified tuner not only has the knowledge of tuning, but also has a Subaru mechanic background stemming back to 2002. If issues arise, as they often do, he will be able to walk you through trouble shooting ideas and steps. This is a service hard to find amongst the tuning community. A bit of advise to all turbo charged customers, be prepared to perform a "Boost Leak Test." Hit up google for various How-To tutorials on this test FAQ Q: I was tuned by iaTUNING in the past. Can you open my old map and work from there? A: The answer is a bit complicated. Yes, we can open the old maps, but when we save them they will adhere to the latest revision 4.0+ software. If the vehicle had deleted emission compliance parts, then the diagnostic trouble codes (DTC) will turn on with any new map version we save. Q: I'm interested in tuning my car. What do you suggest I do prior to purchasing a tune credit? A: First and foremost, the vehicle's standard maintenance should be up to date. Things such as worn spark plugs, dirty MAF sensor, old fuel filters, all create issues while tuning. In addition, we are strong supporters of Boost Leak Testing or Smoke Testing prior to any tuning. It sounds impossible, but a small 4mm hose leak can, and has, resulted in a 70HP power loss. With that said, make sure the engine is air tight, including the pre-turbo exhaust stream. Q: Does iaTUNING offer FLEX Fuel tuning?A: Yes, we offer Flex Fuel tuning through the Cobb accessport and current applicable platforms. Please consult with Cobb as this list continues to grow. Q: If I just want a map for e85, can you tune for that? Not a flex tune.A: Yes, we can tune for this. Before Flex Fuel tuning was relevant, it was common practice to tune 1 map for e85 and 1 map for e10 (example: 93 octane). The end user would then upload the desired map for the intended fuel type. Q: Can you tune the first generation Cobb flex fuel? A: We are not able to tune the first generation flex fuel sensors, or any, that require bypassing the analog output from the TGVs. Please check with Cobb to see if they offer a newer version for your vehicle, and maybe they also have a special price for repeat clients. Q: My car has a pile of Cobb parts, including their prior generation downpipe and TGV deletes for flex fuel. Can you tune it?A: With the change to the Cobb software we are unable to defeat ECU features such as: TGVs, Air pump, EVAP purge, nor o2 sensor (cat delete). For this reason the vehicle would be in limp mode, and unable to be tuned by Cobb. Q: For Open Source tuning are you able to defeat the items that Cobb does not? A: So as to remain an industry trend setter with compliancy, we will hold to the same tuning rules for all platforms, Cobb and Open Source. With that said, no, iaTUNING will not deselect emission control DTCs. Q: My car is a race car, what can I do to have it tuned with non-compliant parts?A: To prove your vehicle is a race car we will need to receive supporting documentation such as proof of State issued de-registration, or non-operable registration status, along with images of the vehicle without license plates. These documents will be kept on file at iaTUNING for a minimum of 5 years. Supported Parts Our experience covers, but is not limited to the setups below.
