bolts Posted July 28, 2017 Share Posted July 28, 2017 Accessories and cluster might be different.. even within outbacks the year of the ecu has to match exactly ...unless I am mistaken? Would a 2006 outback xt ecu work with a 2005 for example? If it does that would be great news I don't see why it'd be any different from the regular LGT '05 ecu. The engines and drive-trains are the same. Link to comment Share on other sites More sharing options...

Shello007 Posted December 2, 2017 Share Posted December 2, 2017 Keeping this thread going. I have done the swap but still running hella rich. No codes showing. Performance is ok. Idles fine etc. but strong exhaust smell. Kept the USDM Ecu, changed the exhaust cam gears and other pertinent parts. Tuner is saying he can't seem to find the cause off knock. Anyone else saw rich conditions or exhaust issues with this swap? Link to comment Share on other sites More sharing options...
bolts Posted December 3, 2017 Share Posted December 3, 2017 Well thats great... do you know of any vendors that would have one that would solve this? Any versions/models in particular that I should be on the lookout for? It's kind of a broad spectrum and I'm having a hard time tracking one down Any help would be greatly appreciated bolts They're not that picky.

Shello007 Posted February 25, 2018 Share Posted February 25, 2018 So the motor swap has been completed since Jan-14 and all in all, very happy with the EJ20x. Near the end I was scrambling to figured out the TMIC and DP situation and valleylegacy on these forums hooked me up with an HKS JDM downpipe and stock JDM TMIC to button it up. The car now has 6300 miles on it since completion and is still running stock USDM ECU without the Quad AVCS. Haven't even taken it to get emissions tested yet because I've been so busy. Used Tactrix OpenPort 2.0 with RomRaider to delete the air pump and the ECU hasn't thrown a code in months. Over the winter when I'd get on it a bit, it'd throw an O2 sensor code, but now that it's warming up, not an issue. It run strong in the mid range, around 5500 it falls on it's face, most likely due to the exhaust cam. Can you elaborate on this air pump? Link to comment Share on other sites More sharing options...
bolts Posted February 26, 2018 Share Posted February 26, 2018 Can anyone confirm if this ECU might work or not in a 2005 M/T outback XT with a swapped ej20x? https://www.ebay.com/itm/JDM-SUBARU-LEGACY-BH9-EJ254-EJ25-AVCS-DOHC-M-T-2-5L-ECU-ECM-22611-AF371/282340746959?hash=item41bcd1e6cf:g:NT4AAOSw-0xYi6G-&vxp=mtr Link to comment Share on other sites More sharing options...

What you are looking for is a Denso 22611AK221. They show up on eBay every once and a while. the '04 models ('05 USDM equivalent) used the same ECU for the sedan and the wagon with the 5-speed trans.

Shello007 Posted February 27, 2018 Share Posted February 27, 2018 so I talked to a guy who made this swap and he told me to keep my EJ25's intake manifold, extend the o2 sensor on the downpipe and VOILA. The car is supposed to run good but I would get more power if I get a tune. Can someone please elaborate on this? Link to comment Share on other sites More sharing options...
bolts Posted February 27, 2018 Share Posted February 27, 2018 Super... thanks It was stated in the discussion above that the engines are not that picky as far as ECUs go... does it alll come down to that model alone or might there be other options?... You are the 2nd person to confirm that particular ECU model... unless that's you yagga.... then you would be one and the same ;o) Thanks again it's much appreciated..

They show up on eBay every once and a while. the '04 models ('05 USDM equivalent) used the same ECU for the sedan and the wagon with the 5-speed trans. Part of the part number is the software that is in the ECU. All you need is the right hardware and you can put the software you want to run in it. I have a JDM ECU in a US car with Australian software. As I said before, these cars aren't terribly picky. Link to comment Share on other sites More sharing options...
bolts Posted March 1, 2018 Share Posted March 1, 2018 22611AH111 22611AK221 Any idea what the difference is between the 2? 1st is EJ20Y and the latter is EJ20X Link to comment Share on other sites More sharing options...
SkippBeatz Posted March 1, 2018 Share Posted March 1, 2018 ej20y comes with a td04 turbo which are in the manuals. ej20x comes with a vf38 which are used in the autos. Link to comment Share on other sites More sharing options...
Dusty B Posted March 1, 2018 Share Posted March 1, 2018 Long time since I lurked/posted here. Glad to see a bunch of you have taken the plunge and tackled this swap. I'm finally back to getting to a place where I would have time/space to perform the task and get my wagon back on the road. I've been reading through everything that has been added and I was still wondering what you guys have been doing for downpipes. Through my searching I've never found an imported ej20x/y with an unhacked dp. Moore performance can get the AVO cast TD04-hla outlet elbows, but take a minimum of 150 days to get stateside they quoted. Maybe Paul from AVO is still on here and may be able to do better. Maybe my internetting sucks more in my old age now, but I haven't been able to find the JDM HKS dp either, even knowing it will come at a high price.

Hayward and Scott in the uk make twin scroll stuff for jdm legacy/sti among other cars. I got one from them. shipping is a bit pricey though.

Thanks for that info. Looks like the link below is the right one for application but they do not list auto/manual or anything. I sent an inquiry email to them to try to make sure I can find the correct one. https://www.haywardandscott.com/subaru/legacy/subaru-legacy-single-turbo-de-cat-downpipe.html I don't know anything about international shipping, but with a $271 price tag (converted from euros), I wonder if it would exceed $400. Still probably not the worst option ever! Link to comment Share on other sites More sharing options...

I'm using a VF38 Is the car automatic or manual? The turbo used and the engine used (20x vs 20y) makes no difference. Edit: I’ll mention it again. The hardware in the ECU is the same for both the M/T and A/T applications. The difference is in the software. Interpret that as you see fit. There will be problems using A/T software in an M/T application though. Edited March 5, 2018 by mondtster Link to comment Share on other sites More sharing options...

l88m22vette Posted March 6, 2018 Share Posted March 6, 2018 This will work, as long as your car is a pre-facelift (2005-07) Pre-facelift: metal ECU housing Post-facelift: plastic ECU housing They are wired completely differently as well, you need to stick to the engine that came from the same version since they're plug-and-play (assuming you added wiring and reprogrammed the immo) Link to comment Share on other sites More sharing options...
Subieguy203 Posted May 10, 2018 Share Posted May 10, 2018 So I’m new to this but I got an 05 lgt with ej20x swapped in but it’s not using the dual avcs... My emissions is due and I can’t pass without it How do I connect it? I’m running the stock usdm ecu and usdm sure harness Link to comment Share on other sites More sharing options...
l88m22vette Posted May 10, 2018 Share Posted May 10, 2018 It won't pass unless you get the CELs turned off. The USDM ECU cannot run it since it was never designed for those connections (exhaust AVCS cam sensors and oil control valves). The engine will run on the USDM ECU, not that well, but it will, so as long as you turn off the CELs and put some miles on it after it should pass.

Zac88 Posted May 10, 2018 Share Posted May 10, 2018 I think in another thread someone got the USDM ECU working with the dual AVCS just by adding a few wires. Link to comment Share on other sites More sharing options...

I'd love to know how, because far as I know the circuits aren't in the US ecu to do it. I'm thinking you're mistaken. Link to comment Share on other sites More sharing options...
