2015-2019 Subaru WRX/STI MAPerformance Cobb Accessport FAQ’s

What services does MAPerformance offer? Will you revise my tunes if I send in logs?

MAPerformance does not offer tuning support, consultation or custom files. We do not provide E-Tuning support and we do not require or regularly request log files to be sent in to confirm the condition of the vehicle. The product we offer is an OTS or “off the shelf tune.” These tunes are intended to provide a tuning solution for specific MAP produced hardware configurations.

Much like any hardware manufacturing process, we do take steps to ensure we are delivering a quality product to our customers. We do not offer custom tunes or hybrid tunes for hardware combinations that are not our own.

How will I receive my tune file?

We will email your tune file!

  • Upon purchase, we ship your new Accessport handheld tuner to you.
  • Fill out the following form for your tune with the below information and we will generate a tune and send it back to you via email.


How long will it take for me to receive my tune file?

We are open Monday-Friday, 6AM - 6PM Central Standard Time. Please allow up to 24 business hours to receive your tune.


Is it safe to run a higher octane tune with my lower octane or octane sourced from a questionable location?

No. If you question the quality of your fuel or the advertised rating, we would strongly recommend that you flash a lower octane rated tune to your ECU.


Are your tune files transferable upon the sale of the car or the Accessport?

No. You must be the original purchaser of either the Accessport or the MAP Tune file to receive support.


Does the MAP Stage 1 OTS tune come free with the Accessport?

Yes, it’s free with the purchase of an Accessport through MAPerformance, and is emailed to you once you receive it in the mail. (Applications where we provide an OTS Tune only)


Does MAP offer E-tuning services?

No, MAP does not offer tuning or E-tuning services. Our OTS tune has been developed in conjunction with our hard parts and corresponding partner and affiliate hard parts.


Can I run an intake with your Stage 1 tune?

No. Intakes that are advertised as safe to use on factory hardware and factory calibrated vehicles are NOT safe to use on MAP tunes as our calibrations alter the tune in such a way that airflow is a critical component of consideration.


Does the MAP Stage 1+, 2, and 2+ tune work with any other intake?

No, our stage 1+, 2, and 2+ calibrations assume that you are running full MAP hardware. It is incompatible with any other parts and we do not offer support for other intakes or downpipes applicable.


Do you offer any tunes for the Cobb intake (or any other company)?

No, our tunes are developed for use with our hardware. Cobb does offer tunes for use with their intakes.


What mods can I run with the MAP Stage 1 tune?

The MAP Stage 1 tune is meant for stock vehicles only. With the exception of a cat back exhaust which does not affect the tune.


How do I transfer the MAP tune onto my Accessport?


Do I need to send logs into you after I flash the vehicle?

This is not necessary as our tunes are more of an Off The Shelf tune, and does not typically require further tuning. If you do experience any driveability issues, or CEL’s, please contact us.
