Repeat E-Tune - Subaru

This is a repeat tuning credit specifically for clients who repeatedly tune the same vehicle, with or without varying parts or fuel types. Example: if a tune was purchased in 2020 for a 2017 STi by customer John Smith, and the same client later returns in 2022 with updated parts for the same vehicle, air intake for example, then they qualify for the Repeat E-tune rate. Credits are non transferrable between vehicles nor vehicle owners.  

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 tuning, 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.
• EVAP system
• TGVs
• Air Pump system

How the E-Tune Process Works for Accessport and Open Source

1. Speed Density Yes or No
If 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. Purchase
For 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 AT
  Fuel 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 Logging
With 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 Logs
After the 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. Completion
We 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.
