Subaru 2015-2020 WRX 6MT Map Updates

WRX CCFv2 Blog Cover

Earlier this year, with the release of Accessport tuning support for the 2020 Subaru WRX, we launched our first subset of Off The Shelf (OTS) Maps using the 2nd Generation COBB Custom Features (CCFv2) ECU type.  Historically, COBB’s OTS maps have been based upon the standard ROM and did not take advantage of COBB custom features or updates from Subaru that were integrated into the CCFv2 ROMs.

We’re excited to officially release all 2015-2020 Subaru WRX 6MT OTS Maps using a CCFv2 ECU definition file.  The following v360 files have all been updated to take advantage of CCFv2 features such as Per-Gear Boost and Ignition Control, MAF Simple, IAT alternate source, and Closed Loop Fueling which provide a much more consistent and reliable calibration.  This ECU type also includes the latest Subaru ECU logic/calibration for the DIT WRX, including battery life improvements for 2015-2017 WRX.  Since their initial release at v350, 2020 WRX maps receive minor updates to boost control, boost limit, ignition timing air temp correction, and fueling.  Other changes of note are the addition of High (HWG) and Low (LWG) Wastegate files.  These can be used on cars that either fall short or overshoot target boost, respectively.

To access these map files, simply update Accessport Firmware using Accessport Manager (to firmware version 1.7.3.1-17011 or newer) or download them from cobbtuning.com/maps.

Once firmware has been updated, select Tune on the Accessport and then choose Restore OTS Maps as shown below.

How To Restore OTS Maps


WRX CCFv2 OTS Blog Section

Map files are available for cars using either 91 or 93 octane fuel.  Stage 1 and Stage 1+BigSF map produces peak gains of +14% HP / +13% TQ over stock and maximum gains of +98% HP / +98%TQ over stock when using 93 octane fuel. Stage 2 and Stage2+BigSF produce peak gains of +19%HP / +40% TQ over stock and maximum gains of +110% HP / +110% TQ over stock when using 93 octane fuel.  Due to the significant power drop observed at redline on the stock calibration, percent gains are drastically different than previously published.  With OTS Maps carrying power out all of the way to redline, the differential at 6800 RPM is over 100% for both horsepower and torque.  As you can see in the graphs below, this is obviously an extreme condition.

Big SF Intake System for 2015+ WRX

745110_gallery_01

Cars utilizing a Stage1+BigSF or Stage2+BigSF map with the COBB Big SF Intake System can expect to see 10-12 HP in addition non-SF dyno charts seen above.  Intakes are often accused of being simple noise makers and not making much of a difference in power, but that is not the case here!  Replacing the factory intake with the COBB Big SF Intake greatly reduces pre-turbo restrictions, allowing the engine to be more efficient and make a bit more power.  Interested in other mods?

Do I have to remove delete 2nd restrictor pill to run the Stage 2 Big SF? I have been running Stage 2 Big SF v302 for a while now. What are the advantages of v306 over v302?

Thank you

Map notes for 2018 WRX 6MT ADM show in the Revision Notes at the bottom that v351 is the latest, but I only see v303 when I enter my car details. I updated my Accessport to firmware version 1.7.3.1-17011 and chose Tune | Restore OTS Maps, but v303 are the only ones present. The article in the blog actually talks about v360 being the latest and greatest and yes, mentions some improvements for my ride.

    Hey David,

    We have not added the CCFv2 ECU type for ADM WRXs yet so unfortunately these updates are not available for you. The v303 map you have is current for your car, it looks like we may have made a mistake adding the v350 and v351 updates to the ADM Map Notes Page. I apologize for the confusion.

      Hi Marshall,
      Please add the CCFv2 features to ADM vehicles. We’d like to see ADM & USDM updates coming out simultaneously; is there that much difference between the two versions that it can’t just be made part of the normal production process to produce both versions at the same time? We feel a little neglected always being last to get updates, and only after begging and pleading… “Thank you for your consideration.”

Are these updates also coming to the CVT?

Hello, I’m running “2015 Subaru WRX MT USDM Stage 1+BigSF Map, Performance, Stock Throttle, Normal Wastegate, 91 OCT/95 RON, v3.01” and when upgrdading to “2015 Subaru WRX MT USDM Stage 1+BigSF Map, Performance, Stock Throttle, Normal Wastegate, 91 OCT/95 RON, v3.60” I get a warning that says this map doesn’t match my car. I have a 2015 WRX Manual with BigSF so I don’t get why I am getting this warning. Could you help me?

    Marshall on July 7, 2020 says:

    Hey there, the reason you’re seeing that error is due to the difference in ECU type moving from the old map to the CCFv2 version. This is expected behavior and you will be able to flash to that map once in-car.

      Hello Marshall,

      Following up on my July 7,2020 comment, I find this map dies on me at around 3000-4000 RPM. It could be due to that I don’t have the latest update needed, but still, I find version V301 works much better on my car. I wanted to ask you, what is the latest version available for the second to last ECU update )the version prior to the this last update) and where can I download it? as a reference I have a USDM 2015 WRX stage 1 + BigSF, 91 oct, normal wastegate.

    Our Subaru team some large projects for the USDM market right now but we’re hoping to add the CCFv2 features to supported ADM vehicles in the future. No ETA right now, though.

      Hi Marshall,

      My wife has been super happy with your current ADM HW stage 1 tune and has made both our experiences in the 2015 WRX much more enjoyable.

      I would like to get the latest 361 updates in as well to better manage the engine characteristics as it seems to be little rough on the highway producing what it would feel like if you had an unbalanced tire however all monitoring stats are normal and without issue.

      Looking forward to the update and a possible ETA

Awesome work y’all! I just placed my order for a Stage 1+ Big SF package and cannot wait to get it. Will my access port come with these updates or I do need to update the firmware when I received it?

    Firmware is typically updated before shipping but it’s always a good idea to double-check.

James Maxwell on August 8, 2020 says:

My currently loaded map is “Post-recall 2”. When I try to put a “Post-recall 3 CCF Gen2” map on the AP, I get a warning about the map not matching the vehicle. Note: This is on a 2015 WRX USDM MT going from v301 to latest (v361).

Is there any reason to be concerned?

    Marshall on August 10, 2020 says:

    Hey James, this is expected. The AP is just letting you know of the ECU definition change but should allow you to move forward with that change since they are within the same vehicle offering. Feel free to reach out if it gives you any trouble!

    Hey Patrick! We’re hoping to add the CCFv2 features to supported ADM vehicles at some point. We were hoping to get to Australia this year to work on that development effort but have pushed that plan into 2021 due to current situations.

Hi, I’m curious as to what kind of power differences you guys are seeing from the 93 map vs the 91 map.

Asking because I only use Shell 93 gas, but prefer to use the 91 map solely out of caution.

    Marshall on February 1, 2021 says:

    Hey Scott! We typically see ~5% increase in power/torque when moving from the 91 to 93 version of our Stage 1 calibration for the DIT WRX.

Eamon Gavin on March 24, 2021 says:

Regarding “This ECU type also includes the latest Subaru ECU logic/calibration for the DIT WRX, including battery life improvements for 2015-2017 WRX.” I’m running a custom tune. Do I need to have the dealer flash the ECU with the fix or can I have my tuner build off the v360 map to gain this battery fix?

    Adam Hill on March 24, 2021 says:

    Hi Eamon,

    You will not want to involve the dealer in that process as this is a custom ECU ROM that only exists via COBB software. If you already have a custom map from a Protuner, you will need to contact them in order to request an updated version with any additional features or calibration changes.

Randy Reamy on March 31, 2021 says:

I was told today that the stage 2 maps listed above are no longer offered. Only stage one. I shouldn’t have flashed the accessport per instructions. I’ll have to send it back. I have a car that was salvage on stage 2 or 2+. I was told that there are new hard parts that cobb is releasing and that they won’t release the stage 2 till those come out. I guess I’ll have to buy one used on ebay or something. Do accessports come with stage 2 by default before the firmware flash… or were those downloaded from the cobb website? If so they also pulled them from the website. Shaking my head so much right now

I’m having the same problem as Randy Reamy, whay happend to stage 2 and 2+? I haven’t updated my accessport yet and I’m glad because I still have those maps but was interested in version upgrade. What’s the deal with deleting the 2 and 2+?

    We are working to update our J-Pipe solutions for the 2015+ Subaru WRXs in a manner that will no longer require the suppression of certain DTCs. Once the revised J-pipes are available (hopefully early June) we should be able to re-release those affected maps.

      So is it impossible to get the stage 2+ map for the older Jpipe because i just bought a brand new older style jpipe will i never be able to run this pipe now?

        Previous versions of our Stage 2 and 2+ files are no longer available. We will are hoping to re-release new versions of those files in the near future when updated J-Pipes w/ GESi cats become available. Having the car custom tuned would be an option if you are in need of something more immediate. Sorry for the inconvenience!

Hi Marshall, hypothetical question.

Say I have the previous v361 OTS tune files, but have a Grimmspeed or TurboXS catted Jpipe, will it be compatible with the tune? Or do I specifically need Cobb’s Catted Jpipe/Turboback?

    Marshall on May 18, 2021 says:

    Hey Dan! We have not tested either of those J-pipes with our updated map files. They are specifically calibrated to be used with our GESi Catted J-pipe and we cannot recommend using alternate components.
