Sure! Thank you!
I just love my car, and a 6MAT would be incredible. And since I may need a replacement anyway, why not? Lol

Is it worth it? Only if you want the best gas car ever built. It's fantastic. It's about like going from H4 to H6. It's not any faster and it doesn't save money but it is more fun and more rewarding.

Personally I'd EV swap it, knowing what I know now. For an AWD sub 4-second 0-60 and 300 miles of range it'd cost $50k, which is less than I spent on the EZ30R in two years between the swap and gas/maintenance... Then you can road trip your sweet spaceship everywhere practically for free. But yes - If you want to run the EZ30R the 6MT swap is fantastic and you can do it for $5-7k if you're smarter than I was.

If you are interested please join the "EZ30R MT Swappers" group on facebook. We have a google drive with a DIY swap tutorial walkthrough and all the CANBUS code and wiring instructions. Three 2008s have been swapped now that I know of so just copy what we did and you'll be set.
 
Wow, I did not think it would be possible to do a manual swap like this, that's amazing. I'm very interested as we recently swapped in an EZ30D into our 2001 Forester (thanks @Brucey for the inspiration), it would be more fun with a 5MT instead of the 4EAT. Now I'm thinking it wouldn't even be that hard, since there's no CANBUS to deal with ...

Maybe I'll take another look at it, part of the reason we didn't manual swap was the need to register it in California.
 
No I changed the transmission out entirely. It was more difficult finding a matching one than I thought it would be. (I still didn't get that right as I'm just now learning.)

Still working out a couple minor issues.


If you need a TCU I have a spare but I doubt it's the issue. They seem really robust unless flooded or spiders nest in them or something like that.

If you want I would make a thread for your car to help keep this one focused. :)
I've been discussing with others, I think I will try swapping out TCU.

Wanna sell it to me?
 
@Rcnesneg

what Arduino did you use ?

I think @west_minist = XRT Ed has also done some rom-raider work for H6 people putting manuals in.

EVTVdue EVTV Motor Verks Store: EVTVDue Microcontroller, CAN Tools, EVTVDue2

Ed at XRT tried to tune my manual swapped EZ30R but couldn't really do anything to change much except throttle pedal mapping which I didn't like. I wouldn't bother if you are staying stock. He supposedly could change something I didn't have access to in the ecu programming but I couldn't tell a difference in how the car operated. Just get Romraider and change the AT idle values to the MT idle values and call it good. Unless you live in california or NY then you can't touch your rom anyway. It runs fine on the AT rom and is probably best to just leave it.

so this would be the original Arduino Due (better pics)
 
Rcnesneg, if I remember you correctly, I stated to you that you do find some cars in tuning just somewhat works the same, which in my humble opinion, is not normal and need to look at mechanically.

Update - The new owner has the manual swap in his other Spec B clone outback now - On legacy suspension there are apparently no issues with shifting weird or anything like that. So this suggests the shifting issue was related to installation in an outback and/or the 1/2" lift it had.
 
Well she flew through emissions - No issues. They didn't say anything about the manual and honestly I think they thought it was factory. And since nothing changed with the ECU, emissions, exhaust, etc, there should be no difference anyway with the TCM replaced by the arduino but it's good to have the verification.

The tech did stall it the first time he let the clutch out... Lol...

This was for Salt Lake County. They do an OBD2 check and a visual inspection - Not sure about a sniffer. It took two techs about 2 minutes to do it.

Update Sept 1 - And she's off to her new home! A fellow Subaru nut bought her to go live with his 2008 Spec B swap Outback. And I'm off to my new electric wagon. Feel free to message me or reply to this thread if you need to - I'll probably get an email notification.
Question on this - do you know what does the Utah emissions check look for?

I ask because the CA check looks for readiness monitors, etc. - but it also runs a checksum algorithm on the ECU. The latter is MUCH harder to pass with a modification this extensive.

There is no modification needed to the ECU so the checksum will pass normally. The ECU still thinks the car is stock and they don't care about the transmission so there's no difference there.

In Utah they don't check the checksum and I had some tuning to clean up pinging, etc and add the manual values for idle speed, etc but I don't think it made any difference. I would recommend to keep the stock tune.

This "extensive" modification does not involve the engine or ECU or exhaust systems.

What does phase 1 mean? Do you mean "stage 1" where someone just has a tune on your ECU? If so, yes. This doesn't affect the ECU in any way. It swaps out the TCM not the ECU. Your ECU just thinks it's always in 2nd gear and drive.

Sorry I meant gen 2 outback from an 03 with the EZ30D stock ecu with manual swap
I'm not sure. Does the '03 have canbus communication? I know its been done before, there are some swap groups on Facebook. I just don't know. You might have to start from scratch like we did and do your own reverse engineering of the communication system like we did.

ah ok was just seeing if this could possibly work on older model since most are are running gen 3 EZ30 just to see if i can run it as is without the stand alone for the time being thanks for the help

It would definitely need some work. It was very specific for the 2008-2009 model years. Even for the 2005-2006 and 2007 it's a bit different but I'm not sure of the specifics. Ask the guys around in here and they can probably help you.

The black box TCM replacement idea is sound, you just have to figure out what it needs to do.
 
Buy a donor MT car of the same year and swap everything over. Budget $5k over the cost of the donor and you're good to go. Or - buy the donor and drive it and have two?

If you want to go Spec B 6 speed manual it goes up quick. I spent 5 figures on my swap... I could be rolling in a Tesla Model 3 right now after the car cost, suspension/brakes/steering and transmission swap - and pay pennies for maintenance and energy...

Only do this sort of thing if you can't buy it - IE: MT swapping a 3.6R. I would love to see that, and it shouldn't be any worse than our 3.0Rs.

If you're serious - we have a lot of R&D knowledge and would be interested in seeing your project progress with a CVT swap.
I’m very interested in doing a 6MT swap into my 2011 Legacy 3.6R Limited. I’d really like to know if you (Peter and Mitch) made any plug and play units to replace the TCM. I’m very excited about the way you made this work while running the factory ECU. Since my car has the 5EAT currently, I’m hoping that your solution will work in mine as well albeit with some minor tweaks. I have already bought a 2012 LGT as a parts car for most of the needed parts. It has the split case 6MT with the proper mounts on the bell housing to fit my car. I have yet to find any examples of anyone who has manual swapped a Legacy 3.6R and everyone I talk to says I would have to run a stand alone ECU to make it work. I would prefer to run the factory ECU and keep all the other great features that the car already has. I’m also planning a future upgrade to a Raptor supercharger system to go with the Raptor headers and custom exhaust that I already have and then would like to have XRT do a tune on it to dial everything in. Any assistance you can offer would be greatly appreciated! Hopefully this late post finds its way to you and maybe starts a new thread or continues this one.

We never made any plug and play units. I sold the Outback and joined the ev world and don't remember it all that well but it was relatively easy for me to figure out at the time. You will need to make your own little black box and figure out the canbus to use. You may be able to use very similar signals to what we used, especially if the TCM is similar. The swap guide on Google docs should have most of the info you need from us. The Facebook group might be helpful too.
If you have eyesight that might cause some issues but I'm not entirely positive.

Good luck and please document what you do for future enthusiasts!
