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.

    Would I have to bring my vehicle to you guys to get it tuned or would you be able to remotely tune it from your shop? Just recently got a 2015 3.6r and want to do a little bit of work to it and was wondering how the tuning aspect of it went.

    I have a stock 2015 WRX CVT what would be the best route for stage 1 tune? I’ve heard COBBs1 maps aren’t that great?

    Good Day!
    I just wanted to say i think its pretty cool to see a team that are tuning CVTs. It gives us CVT guys some hope lol. I have a 2013 legacy cvt with the FA25. I just wanted to get more information on the tuning options and maybe pricing.

    thanks

    Hello
    I’m doing your recommended upgrades for my 2019 Wrx CVT. I have a Mishimoto CVT cooler,I will be purchasing a Grimmspeed Stage1 :CAI & EBT.
    I want to add an Aig AOS, any thoughts?
    I have the STi exhaust option installed at factory, is it sufficient during this stage of the build?
    also i’m a NOOB , which tuning source: COBB, Tactrix or EcuTek
    do you recommend?

    Hi, I am looking at installing a Nameless Axleback muffler delete and Takeda Stage 2 intake very soon on my 17′ Legacy 3.6R. Would tuning be better served after the installation or before and what might the potential power gains be in your professional opinion? Thanks!

      It is better to start tuning around the time of the installation. Please email me if you have any further queries.

    I have a 2015 FXT CVT with Cobb Accesport. It has been custom-tuned, but I am experiencing and very inconsistent knock. DAM drops at to .562. at times. I am looking for a second opinion.

    also this is my daily driver ,wish to keep her as reliable as possible .
    I like the parts list you put together to accomplish this, I want to add these parts in stages can you please advise as to what parts to install 1st 2nd etc.
    thank you,

    I am Interested in tuning my 2016 WRX CVT, any recommended parts to install before tuning? I want to achieve around 250-270 whp and still keep the transmission reliable and not slipping. is that even possible ?

      Yes 250 and upward to 270 is very much possible. I would advice an opensource tuning that allow the access of maps that increases the line pressure to the clutches.

      I am interested in tuning my 2.5i limited Legacy CVT because it’s just a slug. The car is otherwise stock(for now). Is it a possibility to get you all to tune my CVT for better daily useage?

    I have a 2015 wrx cvt and am looking to push a reliable 350whp. What all do I need to do to ensure that my transmission will not slip?

    I have a 2015 FXT with Cobb’s OTS Stage 1 on 93 fuel. I plan to install an intermediate pipe, but not replace the J-Pipe or do TGV/EGR changes.

    Would an e-tune with the intermediate pipe be capable of dialing back some torque to not stress the CVT as easily? I currently don’t have a CVT cooler and am not sure if a shop nearby is capable of welding a mounting bracket and topping off the CVT oil – shops around here are finnicky with mention of CVTs. I want the i-Pipe + etune for some better mid range punch but also some extra sound (running a 2016 WRX midpipe and 5″ mufflers).

    I’m looking at buying a ’18 WRX with a CVT transmission. I want to tune it, but after reading and watching videos I see that most people aren’t impressed by the COBB stage1 tune. So I figured I would just go right to the COBB stage2 tune. Doing some research I’ve seen some people talk about the CVT failing….This is going to be my daily driver, so having a transmission go out on me isn’t really an option. Is there anything I can do to mitigate that or should I just look at another car whose transmission can handle a more hardcore tune?

      Per our email to you, the best option for tuning the CVT is opensource. Please email me and let me know if you are interested.

    I have a 15 WRX cvt with k&n intake and blox muffler deletes. Can you suggest a good daily tune. I wish the transmission had steps all the time not only in sport sharp. Could you do one for sport and just have intelligent mode for cvt mode.

    Car : Forester XT 2014 Cvt currently stock with 139000 kilos on the Click. Going stage 2 (catless jpipe with catback) and aem intake.
    Im worried about the weak Cvt..

    What would the cost if a safe and reliable tune.

    Thanks,

    Hello, I have a 2015 WRX CVT with a Cobb Stage 1 OTS tune. I have been unimpressed so far and seem to be having some issues. I would like to discuss tuning an fixes to my issues.

    [quote]Im working with Ed on my 2016 Outback 3.6R. he has been so helpful and communicative with each step of the project. Its also quite amazing how fast he responds. He has been working on increasing the responsiveness of the CVT while optimizing the power output of the engine. the car is so much faster to respond now and certainly pulls harder. Certainly makes it easier to merge into traffic.[/quote]

    I own a 2017 WRX CVT with a TR690Tranny @290Hp Ecu.tek Tune. Im encountering slipping. Im about to open my tranny. anything you can recommend me parts/buy?

      I would recommend you upgrade the clutches. Please switch to Redline Non-Slip CVT Fluid or Motul CVT Oil.

      In addition, please have the tuner tuned the car properly to apply the proper tuning help the transmission work properly.

      We would be willing to retune to demonstrate proper operations of the car and transmission.

    Hi there,
    I have a 2014 foester 2.0xt premium with a cvt.
    Cart is fantastic but trans is very jolty and shuttery.

    how are you .
    I have a 2010 subaru legacy(ej253) with a TR-690 usdm.
    I have a slite knock or ping, only at lite throttle from 1350 rpm to 1420 rpm, which makes me use premium gas just because of this.
    it looks like subaru tuned this tranny like if it was a diesel or something, the car weights 3350 lbs. awd fulltime , ironicly the car performs well beyond quater throttle.
    this is what i think should fix the problem #1 increase the cvt lite throttle to 1450 rpm or a richer afr mixture of around 14.01= to 13.7 = 1 .
    Please advice , am looking to do this by october or next march.

      Usually tuners just tune the engine as normal, not taking into relation the Transmission operations with the engine and vice versa.

      You are always welcome to email us, but we will be ready for you. Once on-broad, we will apply the following to your tuning:-

    Are all things the same for Forester SJs as they are for the WRX 15+? I am curious about learning more.
