2020wrxcvt_blog

Subaru’s 2020 WRX CVT is now fully supported within the COBB product line.  We have confirmed fitment of our bolt-on upgrades such as the Big SF Intake System, 3″ Turboback Exhaust (both Resonated and Non-Resonated), and Air/Oil Separator.  The SUB-004 Accessport comes loaded with Off The Shelf Maps to support common bolt-on upgrades.  For those interested in taking their 2020 WRX beyond the scope of our Stage Power Packages and Off The Shelf Maps, Subaru Accesstuner and Accesstuner Pro both now offer full tuning support, including COBB Custom Features.

For a complete list of compatible parts, visit the 2020 Subaru WRX CVT USDM Vehicle Page on the COBB Tuning website!  Have a different model year?  See our expansive list of WRX aftermarket parts.

Off The Shelf Maps

Off The Shelf Maps for the 2020 WRX CVT use our CCFv2 ECU type, taking advantage of features such as MAF Simple and Closed-Loop fueling to deliver higher, more consistent power.

Each Accessport comes pre-loaded with an assortment of Off The Shelf Maps that support from a completely stock car up to a car with a full turboback exhaust and COBB Big SF Intake System.  Map files are available for cars using either 91 or 93 octane fuel.  Stage 1 and Stage 1+BigSF map produces peak gains of +7% HP / +13% TQ over stock and maximum gains of +19% HP / +19%TQ over stock when using 93 octane fuel.
