RomRaider forum, any place that mentions your ECUID, CID/CALID, members on here who have a 6th gen FBxx and talked about an XRT (Ed) or ThrottleHappy (Matt) t00n or have it listed in their signatures.

Keep it headers into cats into y into single mid-pipe into dual axle-back mufflers (just like stock). Try to stick with a 2.25-2.5" ID max. Avoid 3" if possible (no/not much high RPM hp/tq gains, worse low RPM tq). T00ning is no problem - plenty of ppl who can help with a 2010-2014 3.6R. Stay open opensource - avoid Ecutek, avoid any locked down opensource tunes.

meh, pass - not worth the hassle and cant be properly tuned anyway without a standalone aftermarket ECU.

Skip a true dual - caused all kinds of unexpected issues that pickler was unable to tune out or eliminate mechanically. He gave up trying and sold the car as fast as he could. For $2K CAD you should be able to go custom header-back. Lots of good info on what you want on a 3.6R in the 3.6R mods thread. Anything cat-back or y-back will not net any real gains on this platform. The gains are all up front (headers/cats/y-pipe section).

Egos, ignorance and politics got the better of this thread. t00ning Hitachi-based Subarus (for better or worse) is well alive, just search for what you need beyond this forum - easy to locate and contact who you need, plenty of ppl and firms out there happy to help you part with your time and money. On the other hand - in this day and age, it might be best to just leave these econoboxes alone and keep them as stock as possible. Should help with trade ups to Ascents and upcoming 7th gen.

Enabling for audiophiles... https://www.sonic-design.co.jp/lp/subaru2014/

Yup in all Denso-era and many Hitachi-era Subaru ECU ROMs there are not just AF Learn A-D-F range limit tables, but also an upper and lower bound values that define from what g/s and to what g/sec AF Learning #1/2 and 3/4 (only #1/3 on H4s) can register and be recorded in memory. If defined, you can tweak both and they do take effect. Its just a question of establishing or expanding the ROMs definition to get at them and then either disable AF Learning say below 3g/sec or above AF Learn C (to avoid D bleed into OL). The latest 'rage' on Hitachi ECU Subarus is running full-time Closed Loop, as opposed to our good ol' full-time Open loop. I guess in theory, it should be possible to enable full-time CL on any OE semi-wideband A/Lambda Sensor Subaru... knowing it wont read any richer than 11.x:1 (some can be recalibrated to be fairly accurate down to 10.5:1 but no more). I wonder what full-time CL would do on an old 4/5th gen LGT if it could and would be configured... maybe it would help here or be beneficial in general?

Sorry to hear BBPeik... GLWS.

Yup, slowly RIP. I contacted the site owner in May and offered up Ascent photos. He declined and said sth along the lines of sailing into the sunset. The page is still free of the typical photos and will likely remain this way. http://www.cars101.com/subaru/ascent/ascent2019.html

Dex VI synthetic fluid is optimal and a fine replacement for the spec Dex III. And yes, fresh Dex III and VI are both bright red - very similar to other ATFs. Only takes 24 months or so for the Dex III to turn dark and spent with some spirited driving. As these cars age, its actually a good idea to replace the PS fluid every 12-18 months. Its cheap, its quick and a good preventive maintenance item to keep the pump in decent working order as long as it will decide to last.

Yup... ol'girl still looking good. 1st world problem of the day: Not sure which is a bigger garage queen - GTEaser's or DeltaSniper's LGT? Both look like they just rolled off the production line in 2011/12.

Yup, in 2018/2020 (and even back in 2014/15) MTs made no sense on a modern fairly heavy Subaru equipped with S-AWD and multiple nanny systems. The HTCVTs (TR580s, TR690s) do a great job and even the vanilla CVTs are a far better paring for these boxer S-AWD combos. This is why most of the fleet sold on the domestic market is CVT. USDM Subarus are slowly heading that way as well. This should be the way AT/CVT torque is derived (VD and real dynos): https://legacygt.com/forums/showthread.php/experiment-and-thoughts-alternate-5eat-dyno-test-method-251156.html?t=251156 And whoever operated that Mustang dyno should've used 5th 'gear' for an Ascent. 4th is fine but will inflate the number a bit (I bet they didn't account for below) Ascent HT-CVT 8 manual model setting. Manual mode 1st 3.227, 2nd 2.100, 3rd 1.535, 4th 1.191, 5th 0.933, 6th 0.759, 7th 0.602, 8th 0.467. final drive 4.444 WRX/Levorg HT-CVT modes/ratios: I, S modes 1st 3.505, 2nd 2.238, 3rd 1,641, 4th 1.194, 5th 0.880, 6th 0.611. Final drive 3.90 S# mode 1st 3.505, 2nd 2.405, 3rd 1.855, 4th 1.544, 5th 1.258, 6th 1.032, 7th 0.856, 8th 0.716. Final drive 3.90

Sadly no, both vanilla Subaru CVTs and HTCVTs suffer from slightly higher ~ drivetrain loss vs 4EAT/5EAT slushboxes. CVTs are also mated to a TC (smaller than regular AT) so they are cog-slushboxes if you will lol. A lot depends on how that Mystang dyno was configured, what software its running, what 'gear' was used in S mode for the run, etc. I guess the only somewhat reliable benchmark would be to learn what a bone stock STI or EVO puts down on the same rollers with the same settings in a similar gear ratio gear. Otherwise, without any context and especially with the CVT, these Ascent #s are rather meaningless. The torque alone is likely skewed... dyno software across the spectrum still can't properly calc wtq for CVT, AT cars.

Drivetrain loss for HTCVT is actually closer to ~29-31%. 260ftlbf at the wheels is barely ok with this curb weight, try 320-340ftlbf on a Stage 2 CVT WRX/Levorg on pump E10 AKI93. BtW just got these in the mail for bad-welds nostalgia.

Sorry to hear, reach out to Ron Watson (PhatBotti). Assuming AP and e-tune is fine. https://phatbottituning.com/ There is also a great Canadian-based tuner who can potentially help - VitTuned. http://vittuned.com/ http://blog.vittuned.com/

Depends on if you need in-door or outdoor use. Look accordingly. OE one is the best bang for buck and good fit (especially the folding mirrors and shark fin antenna) California car cover is likely best quality, but overkill for your use. Ive been using a car cover for mine since day one since it was typically weekend-use only.

Nice! China Cusco Master Cylinder Brace for BM/BR.

tdck is now offering transmission mount inserts (different hardness, color, etc.) for most of the 5th and 6th gen slushboxes (5EATs, CVTs, HTCVTs). Legacy/Outbacks, XV Crosstreks, Imprezas, soon also FXTs, WRXs, Levorgs: https://legacygt.com/forums/showthread.php/cvt-transmission-mount-insert-cke-ssp-267950.html?t=267950&highlight=cvt+insert

Hahaha, had that and similar posts on selective ignore. Nothing personal xt2005bonbon. Yes, BtSsm + Tactrix OPv2. Basic profile doesnt expose Targest Boost or FFB so no luck with AF Error or Boost error... and I have a feeling no one will ever define or find SSM params for those on these newer Subarus... all in E-OBDII Mode 0x22 and 0x23 la la land. COBB has the low down on that and isnt talking (likely paid a hefty amount to get the Manufacturer specific E-OBDII PID defs or same amount in man-hours by now COBB staff, ex-Engenuity/RR gurus). Can confirm both intake and exhaust L/R VVTs, AF Learn/Correct 1 and 3, Boost, MAFv and g/sec as well as Load and EGR Steps, IAM, FKC, TPS, ECU PIDs work fine. Same with CVTF from TCU. FKC noise around the usual 0.8-1.2 g/rev and out of/at low boost, but continued to build and stuck around even in lower 'gears' at >1.5g/rev and >5psi. Just a fairly typical stock FAxxDIT t00n. Overly aggressive timing in the cruise range of the timing surfaces doesnt like E10 AKI87/89 one bit. And by the look of things, AKI91 or 93 will not be of much help without sone t00n TLC.

You might want to suggest it to the OP. Thank goodness no Stop-n-go or cylinder deactivation or variable compression on the latest Subarus. All these techs are just overcomplicating and asking for trouble 5, 10, 15 years down the line.

LSPI has been discussed for at least 4 years on North American Subaru forums and maybe 6+ years across the ponds. And of course a few more years over on the Mitsubishi, Mazda, VAG forums. What I saw wasnt LSPI. There are even t00ning strategies and yes also mechanical mods and oil/fuel additive choices to try battlying it. The t00nong starategies employed by both Subaru/Hitachi and the aftermarket to try to limit/eliminate most of it on the FA20DITs and FA16DITs... so the same could translate over to the FA24DIT.

Nicely done IceWolf, she's coming along... Turns out Kiwis are offering a slightly modified 3.6RS to bid fairwell to the BN/BS and the EZ36D+TR690 combo. Sad to see these engines go instead of getting PI/DI, maybe higher compression with a re-revised bore/stroke and tad lower displacement target, a decent set of OE exhaust headers and 8 simulated gears like the WRX/S4/Levorg. https://www.subaru.co.nz/offers/sti UPDATE I see you guys wrote about the RS a few pages back.. and likely earlier too. Cool! 8-10 years ago we also used to contact Kiwi and Nihon-jin dealerships and service dept, look up JDM/EDM part numbers in Russian service manual sites... and order parts from NZ, AU, JP, RU, South America. ah those were the days.

Humble, IceWolf I found sth for you... https://www.subaru.co.nz/offers/sti The fabled 3.6RS bye bye H6 edition

I think I spelled it out rather clearly above. Data logged/monitored the dealership demo car with AKI87 and 89 and BOTH showed fair bit of FKC noise. I have no interest in this vehicle, just wanted to see how the base t00n behaves and if Hitachi, Subaru and the unnamed thid-party which builds the stock calibrations (on a contract) learned anything from Liberty/Legacy DIT, last FXT days and then 2015-2018 Levorg/WRX/S4 days. Evidence? Ive given up on providing any on this site and others years ago. People can come to their own conclusions and spend their own time monitoring and logging Ascents if interested.

I will be disappointed if I have to disable electronic nannies every time I try to park at home. Coupled with the SIA QA issues with the Honeywell-supplied turbos and the FKC / FLKC orchestra when data logging a Dealer demo running AKI87 E10 and AKI89 E10 - leave only the S-AWD to provide any level of confidence before the new car smell wears off and daily family hauler status is unlocked.
