Yeah you shouldn't be running the vf48 with running the STi Ecu or a tune man. Swap the td-04 back in man.

The turbo wouldn't be causing the overheating, would it?
Also, how does the new (larger) fuel pump figure into everything? I remember that my STI fuel pump was the same size as the WRX, which happens to be the same size as the Forester XT. So if I put in a larger pump, aren't I running too rich now for the STI ECU?
I will call IAG and Agile Auto later today for answers to those questions, but I want to see what people here say first.

The fuel pump isn't going to cause the car to run rich as long as the fuel pressure regulator is doing its job. They only way that you would run rich is if you bumped up the fuel pressure in the fuel rails. Then the injectors wouldn't meter properly.
I can't help you with the overheating problem. I would check and make sure to burp the coolant in the car really well before assuming that something else is causing it. I had an air pocket in my car and it over heated off and on till I burped the system.

@Yamazaki we may need to just burp the system. I can come over this afternoon if you want and we can give it a shot. Its a little different to burp on a turbo car that on an NA car but same process. Did you add any coolant and remove excess air post turbo swap?

So, yeah. The coolant just needed burping. Car runs fine now except for an exhaust leak that got worse, so now I know exactly where it is. I'll take care of it tomorrow before the meet.

The wife brought the Forester to the meet. No issues. However, she will continue to use the Merc as a daily driver until I source an ECU.

It occurred to me that I still have the ECUtek piggyback unit that I used to have in the STi when it was first built up. Can I use that in the Forester? That'd save me a ton of money and still allow for future modifications. Now all I have to do is find somebody that knows a thing or two about tuning....
[EDIT: I just checked, and it isn't an ECUtek unit (although I have an ECUtek CD), it's a TurboXS tunerPro and some Blitz electronics and hardware I have]

That sounds cool. I downloaded the stock STI map from Turbo XS and planned to just load that into the computer, but I need to read up on how to connect and install everything. Apparently, the utek doesn't even kick in until 60% throttle though. From what I've read so far, that should be fine with what little I've done to the Forester.

Yeah the UTEC can't really control anything until the Ecu goes into open loop as far as I have heard.

So the more I read the instructions and guide, the more I am uncertain about tuning this outside of a professional tuning shop. Unfortunately, IAG and Agile Auto both said they don't deal with the UTEC because it's so old. Turbo XS can still tune with it (as long as I bring all the hardware, which I have), but it'll cost $600 for only two maps. I can get an Access Port for that much and load up a stock STI map for free. I don't know which route to go now.
Should I get the AP and load a stock STI tune (although that won't match my Forester perfectly), or use the UTEC stuff I already have and shell out the cash to Turbo XS? What would you recommend, and more importantly, why?

Hmm.. Are the FXT and STI ecu essentially the same, except for the maps on them? My Tactrix cable should be able to reflash it with the STI image...

So I never did get an '04 STi ECU or a tune of any kind. The wife drives it as she normally does, and when I drive it I place big restrictions on myself throttle-wise. No issues. I am installing a Blitz SBC-iD boost controller and restricting boost A LOT. I also installed the 2.2k ohm resistor to get rid of the CEL for the lack of an uppipe sensor. Everything has been fine, but due to the restrictions placed on it, the FXT is slower than the H6.
Once I make a decision on which one to keep, the other will get the full treatment.

What supporting mods you have running with your VF48? It should give us a better idea of what the issues may be. Any codes (if so what are they)?

GO > Show. Every time.
STI is the new medically accepted term for STD.
I only put in a catless uppipe and 255 lph fuel pump other than the VF48. The code that comes up is just because the uppipe I have doesn't have an EGT plug. I can stop that with a 2.2k ohm resistor (which I already have). The only issue is not having it tuned. The wife has been driving it just fine, but she doesn't ever give it more than 50% throttle and never goes above 3k rpms. (not because of the mods and lack of tuning, that's just how she drives)
However, if I want to drive it, then I am careful to try to keep it boosting as little as possible because of the comments said earlier in this thread.

You can get an open source road tune in the$150-$300 range. Seems like a no-brainer. Of course, you'll need a tactrix cable, so add a hundred buck or so to that.
Or if you want to spend more get a downpipe and an accessport and lead the stage 2 vf39 map.
Depending on what you want to do though, a compression and leak down test might be the best place to start. Verify motor health before adding much stress.

Well, for that cost I could just get a used '04 STi ECU. I definitely don't want to be spending more money on a vehicle I may not keep. And the motor is healthy. It's already been checked by IAG. Strangely, the previous owners were both middle-aged women with no interest in speed. The trend continues with my wife as the primary driver.... This has to be the saddest FXT ever (because it never gets to run and play with the other fast cars).

Well, the wife drove over a sharp metal piece and didn't notice that she drove on a flattened tire for who-knows-how-long yesterday. I happened to have my old Outback wheels/tires, but two of them have nails in them (I'm guessing the wife aims for shiny things in the road when she's driving), but they are 225/60R16 while the Forester tires are 225/55R16. Hinyo came to the rescue with the wheels/tires from his Legacy!
The Forester has depended on him a few times now. Many thanks!

that sucks, on ebay you can generally find one tire with similar wear, unless you want to replace all of them.
98 GT -- Intro to Subaru. Cooked HG, dead suspension, and lots of ricer mods.
02 Outback H6 -- No more HG issues, but ate two 4eats.
09 Subaru Tribeca -- slow and ....um fat, definitely fat.
13 E350 S212 -- No more Subaru!! Why does that make me happy?

Damn it, so much for not going crazy with the FXT. Parts are just too plentiful and cheap here in Japan....
Pics will have to wait until I get back. Here's a list so far:
1 and 2) HVAC surround w/cupholder and celsius HVAC controls
3, 4, and 5) Forester STi lateral links, control arms, and trailing links
6) Rear spoiler w/LED 3rd brake light
7) GD (C type) STi intercooler
I may end up changing my mind on which vehicle to keep after all this....

Yeah, but with the almost $8k worth of body work wanted for the H6 and the toys I'm getting for the FXT, the scale has started to tip in favor of keeping the FXT. I am going to the local Super Autobacs later today. I anticipate further hits to my wallet.
The funny thing is that the H6 is so loaded with "JDM" stuff that there really isn't anything else I can get for it here. Hell, with 8-way power seats (driver AND passenger), extra power outlets, full auto front windows, and more, it's better than an actual Blitzen6 at this point (except for the bodywork).

Well, I went, but there really wasn't much I wanted to buy. I got some rolls of high-quality window film (tint) and air fresheners to replenish my stock at home. The problem is that pretty much anything one would get at Autobacs can be found in the US or online.
However, I am going today to get some things that can truly only be found in Japan....
