Raptor Supercharged 6Gen 2015+ Subaru Legacy 3.6R CVT

The 6Gen 2015+ Subaru Legacy 3.6R #CVT is a nice package, just like the 5Gen to be #Supercharged or #Turbocharged. The latter is the 5EAT for those who may not remember or now starting to love #Subaru. With indirect transmission tuning, there is no issue tuning this model for the performance you need but owners must remember this platform runs tight engine tolerances and does heat up pretty quickly, so it is important that you keep everything cooled – Engine Coolant, especially Engine and Transmission Oil. It would be advisable to run bigger oil and transmission coolers if you plan to run the car above average and in hot climatic regions. Besides heat, the only issue we see for SC operations is the belt, which is nothing new for any SC, and belt torque is very important.

Please note for any boosted application, we recommend cooling the Air-charged and running a BPV plummed back to the intake like in other Turbocharged Subaru’s. If possible, try to keep the MAF in the original location, if not, it would be a little more tuning but we advise full customised tuning and not drop-in-based maps or maps considered to be full tunes.

Xtreme Racing Tuning has been tuning Boosted-NA’s for 10+ years and is your trusted resource for your next project. We can safely say we have been sharing such results for years outside of customers’ own posts for global reference.

XRT Subaru CVT Tuning

Subaru Tuning that affects CVT Operations & Performance by Xtreme Racing Tuning (XRT)

XRT have continue to master the operations and performance of the CVT through tuning and customer feedback and based on the results, we are offering that edge in tuning CVT models like what we did to the 5EAT and the 4EAT.

Generally, the following are expected when tuned (The Transmission Computer is not tuned):

  • Quicker shifting
  • Firmer shifting
  • Appropriate gear selection, if possible, for less labouring or load on the engine
    Less ping/knocking due to the transmission wanting to be in high gear all the time.
  • Less pedal moving to make the transmission shifting
  • Better fuel mileage
  • Easy over-taking and maneuvering due to quicker acceleration due to the above points.
  • Offers greater shifting and operations. This is the mode many requires if you want to have full control when the transmission shift for hill climbing, racing, over-taking etc.
  • Can offers increase response and less throttle lag. Direct throttle control. Now you maybe able to spin those tires on moving off or get that maximum torque to the ground. Transmission Cooler is recommended if you plan to drive her hard with advance CVT indirect tuning.

Subaru Torque Management Patch (XTMP)

Subaru Tuning that affects the Torque Management Operations & Performance of the Engine by Xtreme Racing Tuning (XRT)

XRT continue to MASTER the Operations and Performance of the transmission (5MT, 6MT, 4EAT, 5EAT, CVT) delivery of TORQUE & POWER to the ground in any models utilising the 32bit ECU (Legacy, Impreza WRX & STI, XV, Crosstek, etc). This is seen through tuning, customer feedback and REAL results based and posted all over the internet, including here on XRT.

Addition reviews are here for Auto Transmissions:
Torque Management are already patched in those tuning!

Generally, the following are expected when tuned (The Transmission Computer is not tuned in the Automatic cars):

  • Quicker shifting
  • Firmer shifting
  • Appropriate gear selection for less labouring or load on the engine
  • Less ping/knocking due to the transmission wanting to be in high gear all the time.
  • Less pedal moving to make the transmission shifting
  • Better fuel mileage
  • Easy over-taking and maneuvering due to quicker acceleration due to the above points

Please remember that even Manual Transmission models are affected and are able to accelerate and spin tires easily and freely. Please disable Traction Control.
