E-Tune for Repeat Clients

E-Tune for Repeat Clients


E-Tune for Subaru & Saab REPEAT

This is a repeat tuning credit designed specifically for repeat e-tune customers and their previously tuned vehicles. If you are not a repeat e-tune customer, or are a new owner of a previously tuned car, then you will need to purchase our standard 'E-Tune' credit. 

How the E-Tune Process Works

1. Purchase
For online orders, fill out and include the following details in the 'Special Instructions' section (found in the shopping 'Cart'). 

  • Make:
    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. 

 2. Data Log
With the client's provided vehicle information, we will send the 1st map as well as detailed instructions for testing. Using your AP or Open Source software, you will data log the vehicle. Once the data logs are completed, the requested files will need to be sent back via e-mail for review.

3. Review Data Logs
After we receive the log files we will begin the review process of the log files. Based on this data we are able to make additional adjustments to the ECU file. This revised map will then be sent back by email.

    4. Completion
    We will repeat Steps 2 and 3 until a final map is generated. On average, a finalized map is reached between 3-5 attempts. Now keep in mind, we are not here to hurry along the tune like our competitors. If the tuning process takes more than 5 revisions, then so be it. Our goal is 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 motor. There is of course the exception where mechanical or electrical gremlins lie.

    Map Credits Explained

    • The 1st tuning credit is valid for 60 days from date of purchase. During the 60 days, the car must maintain the same owner and modifications. If a client were to install a larger turbo at day 30, then their initial tuning credit would expire and a new credit would need to be purchased. 
    • After the purchase of the 1st turning credit, all future credits are offered at a discounted rate, see website for current pricing. This applies to the lifetime that you own the car. This offer does not transfer to new owners, or new vehicles. Example: Client John Q completes an e-tune in 2016 and wishes to upgrade his fuel injectors on the same vehicle in 2017. He would qualify for the Repeat Client rate.

    • Alternations to the modification list, while in the middle of the tuning process, will require the purchase of a discounted 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.
    • For vehicle safety and intellectual property reasons, Accessport maps may only be opened by our in-house Certified ProTuner. Also referred to as Locked.

    Our experience stems past the Dyno and includes open road as well as 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; Trouble Shooting, Supported Parts, & Videos. 

    Our highly skilled tuner, Stephen Clark, 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 with modified vehicles, he will be able to walk you through trouble shooting ideas and steps. This is a service hard to find amongst the tuning community. We've even heard stories where tuners will simply stop helping the customer based on their vehicles predicament! 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
