Just did the update, all looks well. My car was 3 updates behind on the ECU.
One question, are we allowed to sell the reprogramming CD when we are done with it? I haven't seen any discs around online, so I wouldn't want Subaru chasing after me haha. Just looking for some opinions. |

Take this offline please. No need to pollute my brother's already fairly polluted build thread further.

Did you check for any EPB, BIU, CAMERA, TCU reflashes or just do the ECU for now? If you have the latest CD (Jul-2018) then you're on the final/last reflash the 2015-2017 WRXs will ever get from SoA. |

Update:
So time has come for me to discuss CVT fluid change. At 50k miles I initially was not going to do this because up to now the color of the fluid and level looked good on my car (I did tests from time to time of the fluid by opening up the fill drain and inspecting its color on a white towel) What caused me to move in the direction of needing to flush the fluid was the state of the cvt cooler lines. Before we go there the Mishimoto cooler is a very good cooler, it is actually a Setrab cooler. Upon inspection the cooler was holding up great. No leaks or other issues with it (Was on my car over 4 years now). Now the lines they offer in the kit are ok but will not last too long sadly. I began to notice numerous cracks in the hoses, mainly at the biggest stress points and that is where the hoses had to make a curve or at the connection points. I reached out to Setrab and decided to purchase their transmission fluid hoses. I picked the ProLine Lightweight Fiber Braided Hose. Item description from Setrab: SUSA LWN Lightweight Fiber Braided Hose is a stainless-steel-reinforced hose with a light-weight nylon outer-braid to provide traditional performance characteristics in a lighter-weight package. Constructed of a chlorinated polyethylene (CPE) synthetic rubber, reinforced with a stainless-steel inner-braid, and protected by a light-weight nylon outer-braid. Continuous operating temperature from -40ºF to 300ºF. Suitable for fuel, oil, coolant, and air. Once the hoses arrived I immediately noticed the good quality, even my master transmission mechanic loved it. You will need two 5.5-6 feet hoses. 21-LWN08-B with the internal diameter of 0.44 inches. I initially purchased the 21-LWN06-B but the internal diameter of 0.34 only can fit the Mishimoto cooler lines (very tight fit) but will be unable to fit the transmission line connectors on the car. I have been talking to various amsoil engineers who worked on the cvt fluid and the decision for me to use their CVT fluid once I need to flush it was made a while ago. I've used amsoil products in the past and even with this car when I had to change the differential fluid. The specs of their CVT fluid are very good and it is rated for our high Torque CVT (TR690). The best part is that you do not have to purchase that enormous amount from Subaru when purchasing the orange CVT fluid. Various sizes can be purchased from amsoil. During the drain process we were pleased to see the good color of the old CVT fluid that was draining out of my car. Still nice and orange but of course a bit darker than new. At 50k miles of numerous fun spirited drives this shows the importance of performing the stock cooler/warmer bypass. My master mechanic was pleased to see this and reported if you want to do it right you bypass the stock cooler. The stock cooler setup eventually burns the fluid and braises the TC and VB internals. Drain and Fill in a nutshell: So process was rather straight forward. Disconnect the lines and clean up the fluid that drained out of them (Have some towels ready). Attach new setrab transmission hoses. Drain CVT fluid from the pan. I ended up flushing 6 quarts out of the pan. The total fill is about 13.1 qts. I filled using the main fill plug and then the second fill plug a bit higher on the side of the transmission. We used my master transmission mechanics transmission pump to pour it all in (Setup can be seen on the photos) Of course make sure the car is warmed up - all is in the manual. Opinion: As stated above I am very pleased with the Mishimoto cooler. Definitely required lin upgrade but that's where Setrab ProLine Lightweight Fiber Braided Hose comes to save the car. Amsoil CVT fluid in my opinion is great. I felt an immediate difference once it was in. To me there was a distinct improved "grip" of the CVT chain. Transmission sounds were also changed to lower levels. Acceleration was another improvement but thats is related to the improved grip. Temperatures seemed a bit lower after spirited driving compared to before. Overall I would recommend the Mishimoto cooler (Its a Setrab cooler), Setrab ProLine Lightweight Fiber Braided Hose and Amsoil cvt fluid. Always special thanks to my brother Perscitus for helping me out with the project and to the secret master transmission mechanic aka "the master." Links to items: 1. Setrab ProLine Lightweight Fiber Braided Hose 21-LWN08-B 2. Amsoil CVT fluid Mishimoto cooler doing well at close to 5 years Drained out CVT fluid (pan is dirty so just focus on color of the fluid) Mishimoto kit lines failing Setrab hose - old on the left and new on the right Filling with Amsoil CVT fluid Last edited by Bellipotens; 10-13-2018 at 10:54 PM. |

Amsoil CVT fluid
I also replaced my gatorback belt with this Continental Elite Poly-V belt while we were at it Also made some connectors for the JDM LED bezels |

I finally joined instagram.
Just search for bellipotens. My profile photo is the black and white front end photo that is the first on this thread. See you on instagram |

I'm sure it's been said before but thank you for blazing the trails on these WRX CVTs.
I think other owners are going to have the confidence to do these things in the future. It's nice to see an option on the CVT fluid as well. |

Always enjoyed the journey with this car and glad you liked this thread as well. As for the CVT fluid by amsoil, to me it is a good choice over the OEM orange fluid.

So pulling everything together with the CVT Cooler, if I'm looking to add one to my '18 WRX, go with the Mishimoto, and instead of using their hoses, go with the Setrab "ProLine Lightweight Fiber Braided Hose" listed at http://www.setrabusa.com/products/hose/index.html .
That sound about right? |

You've answered your own question. Basically yes, that is one way to tackle it. Just get the right-sized and lenght hoses and good fittings.
Alternatively skip Mishimoto all together - use a Setrab unit directly (you'd be missing out on the OE like bracket, AN fittings, clamps) or use an entirely different aux cooler (for example the Ascent OE engine oil cooler). Then decide how you want to plumb your aux or replacement cooler (in-line after rad, in-line before rad, bypass mode, thermo bypass, etc), if you want to add forced convection (slim profile fan). Finally find a solution to monitor your CVTF temps (ideally before you mess with anything to get a baseline) and see how your changes affect the temps (avg temp, peak temp, time to warm up, time to cool off). |

Possibly silly question, but does the HTCVT allow the WRX to "drift" in the snow with TC off? All of the standard Subaru CVTs and the BRZ 6MT I've driven/owned won't let the car get too sideways, unlike my 4EAT 01 Impreza RS coupe and manual transmission 11 WRX, 05 STI and 08 Forester XT.
Whenever it snows I don't get excited anymore since the new Subies don't seem to really "play" in it. |

I'm patiently waiting for the next gen WRX/STI. Depending on if there's a 5-door or not, along with HTCVT, I might swoop one up or wait for the next gen BRZ. I miss having something fun to drive, but having the ABS kick in so early even with TC off is just soul-sucking. |

Great fall photos!
Re recent posts, likely a question best put in the Technical section of the forum. No interest is TC/VSC on/off here. |

Blind spot mirrors and an Ecutek Update Tease...
New blind spot mirrors - ultra low profile. As always I love whatever adds a nice clean look to my car and these ultra low profile blind spot mirrors do just that with a very nice large area of vision. Easy install. No moving parts so they are always positioned well (some blind spot mirrors can be adjusted - like the ones I replaced - gets annoying at times to fix them - not these).

Can someone out in Minnesota pls lend your CVT to MAperformance so they can make maps for us CVT owners to use on our accessport instead of the Cobb maps. MAperformance has semi aggressive OTS tunes for the manuals so it would be cool to be able to slap one of those on my CVT heck Bellipoten should just take a road trip out there for a week or 2.
