Be adding wiring hell, or aftermarket ECU in those thoughts. Also, I don't know my trim levels that well, 3.3 3.0 or 3.6?

Took the car down the street and back today, misfire in cylinder 2, header hasn't changed color at all, but it drove fine. Exhaust shop probably next week for a custom Y-pipe and the cylinder 2 issue and it will be good to go I think. Still a few minor issues to work out, like one of the VVT solenoids had it's connector broken off when I got the engine. I still need to trim up the wiring harness, but that will come with a later project when I pull the whole dash. I need to find a viscous R160 rear diff from an 05 legacy to pair with my trans. Overall I'm about done with the conversion.

Just a note, lime green text on light grey background is very hard to read. Might I suggest blue or dark green, perhaps?

I basically dont have a thermostat, I cut the arches and spring assembly out of one so the housing would seal and not leak. Thats probably how I'm going to run for now. I've been driving the car the last few days and love it, but it desperately needs a tune. The Haltech basemap got the engine running, but I'm not running at my best.

Lol so I just bought a fixer-upper (needs a water pump and some TLC) H6 outback for $1000AUD.

Ok, question for anyone who feels like they get the Subaru wiring diagrams...

https://photos.app.goo.gl/hDPeaiv21numpaEs6

Does that not make it look like the fans are 24v? Do you see a way(or already know of a way) to wire them with just two wires from dedicated relays, or would I really have to choose to either recreate this set up or buy AM fans?

Background if it's needed, these fans came off of an 03 outback wagon with a metal intake EZ30. They came with the radiator I bought, and I'd like to get them spinning instead of spending more money on AM fans if I can.

Hi everyone,

What are you guys running your swaps with ECU-wise?

Pretty soon I'm going to attempt running a H6 with Megasquirt 3 Pro - I'm pretty surprised there's no ECU talk here - anyone running a Megasquirt 3? (Basically I'm looking for companions to help me along this journey which I'll document so future ECU conversions will be a day's task)

I got into ECU related "programming" a while ago, basically checked whether there's any room for innovation, and what actually "tuning" is, wrote some tools in Node/JS that parse the binary data - the sad part is, most of the existing knowledge doesn't apply to what I'm attempting to do - the stock H6 ECU has no turbo logic, and 80% of tuning is actually making the most out of the Turbo's (it seemed to me)

I'm running a Haltech sorry, but I do hope you're serious about documenting your process. I at least appreciate shared knowledge.

I did find useful info/posts on a Megasquirt forum re. EZ30, so don't give up on that. Also look up Wayne at Very Cool Parts.
I too am using a Haltech (2500) to run my EZ30R install (in an 818S).
Regarding schematics- no, the fans don't get +24V. There are 2 +12V inputs each for 2 speeds. I wired only the high speed circuits using the 2 spare relays in the Haltech fuse block. I can share schematics, mark-up's of Subaru schematics, and Haltech diagram (and map) via PM.
Yes, getting the cooling system burped of air and flowing was much harder than I expected. While I have a long run to the rad., the total system is minimized, and I have a definite high point at the cap, it still took work to get burped. 'Works great now though!

I am bailing on my original ecu plan and looking at alternatives, with Emtron being one of them which I have seen mentioned here in other peoples list.

What I don't see is the ability for 2 cam sync and 1 crank sync, is there duel purposed inputs or an build time option that allows for 3 sync's?

Edit - Or are the cam syncs using the digital inputs?

Thanks,
-Jacob

Your best bet might be to try contact the ECU manufacturer with your question. The Haltech forum, and actually Matt himself, was the one who actually helped me fix the problem that got my car running. Give the manufacturer a chance to help you out. Otherwise, get a Haltech(bring on the fire, I expect people to complain), at least the Haltech forums are active, and there are a few of us who run them on our EZ30s already.

I spoke with Nick Pavloski of Emtron today, and the first 3 digital inputs can be used as additional cam sync's. Software looks pretty good and if anyone else is shopping around id give it a look

Good, I'm glad someone was able to get you sorted out.

KHANNN,

The Megasquirt 3x / pro are a good choice for the EZ30. It already supports the 36-2-2-2 trigger wheel. You just need to wire up the crank and cam sensors. Both cam sensors are required for proper AVCS. The AVLS you can do with a basic high current output.

Everything else should be plugging in numbers and crimping wires. MAF support is also really good on MS which mean more consistency over temp/baro/humidity for daily drivers. Also they recently added DBW support which is fantastic.

PM me if you have any questions about MS

During the week, one of the nights when it was thunderstorming outside I popped into the garage and did a little work on my languishing EZ30 swap. Way back when, I wasn't sure what I was going to do about a coolant overflow/reservoir, so I had made a "custom" setup with a small Gatorade bottle. Very trick!


A few months back I learned that JDM GC turbos had the coolant overflow bottle mounted in the left front fender. Hiding the overflow bottle in the fender means I can get rid of the Gatorade bottle on the passenger side of the engine bay, which frees up some space to put the PS reservoir over there where it's supposed to be. (As things are now, I have a Chase Bays universal PS reservoir over on the driver side, which means I have long supply and return hoses running over the top of the engine.) So, I bought a used fender overflow setup from someone here on NASIOC and installed that a few days ago.

This is a shot looking forward from the left front wheel, with the fender liner removed. The "new" overflow bottle is at the top.


Here's a view of the front driver side corner of the engine bay. The yellow cap is the top of the fill pipe for the coolant overflow bottle. There's a short rubber hose that connects the bottom of that fill pipe to the overflow bottle, which is hidden from view by the inner fender panel.


The red terminal on the inner fender panel is for the + voltage coming from the relocated battery. I had to unbolt that terminal, shorten the mounting lugs so that they didn't interfere with the new overflow bottle, then reinstall the terminal. Still need to hook the wiring back up.

Looking from the center of the car over towards the left front corner of the engine bay. In the bottom left of the photo is the radiator cap and the overflow hose connection. Unfortunately, it points the wrong way (since I thought the coolant overflow was going to be somewhere on the passenger side), so I'll have to reorient that to clean up the hose routing.


Next is to figure out the PS reservoir and hoses. I have a few options - an OEM Outback one, plus a couple junkyard finds - just need to determine which fits best and where exactly it fits.

How did you not know about that?! I admit I forget about it all the time and PROBABLY need to look into getting one myself but the car is so low on priority list right now...

Why would I have known about that? I've never had a GC turbo, nor seen one, nor cared about them since they weren't available here.

I guess when you get to a certain point in a group, people just expect YOU to have all the answers.

What I'm curious about is your water hoses and radiator setup. Can you post more pictures of that. It looks like a pipe is mounted somehow, that both of the upper hoses go to, then a hose coming out of the top pass side of the radiator?

You didn't read through all 3600+ posts to find my previous posts about it?!?!



I'm using a stock replacement EJ25D radiator, which has roughly the same core size as an EZ30 radiator, but obviously only has a single upper hose connection. I'm using the EJ25D radiator because the EZ30 radiator is a couple inches taller and won't fit under the hood. This seems to be a problem specific to the BD/BG Legacys. [More specifically, to the USDM BD/BG Legacys, which are all non-turbo. In addition to learning about the GC turbo's fender coolant tank a few months ago, I also recently learned that turbo Legacys had a different, deeper lower radiator support, which would allow the EZ30 radiator to fit. Maybe someday I'll see about sourcing the turbo parts to swap out the core support... but probably not. ]

To make the single inlet on the top of the radiator work with the dual outlets of the EZ30, I had a shop weld up a coolant header for me. If you really want all the gory details, you can work your way through the discussion in posts 1931, 2004, and 2033. "Final" version looks like so:

No idea how well it's actually going to work, as the engine still hasn't run.

Why haven't you started it yet? Looks like the engine is settled in.
