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.

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.

Are these updates also coming to the CVT?

    Hey Robert, we’re aiming to release these same updates for USDM 2015-2020 CVT WRXs here in the next week or two.

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?

    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.
