Would you like to borrow mine, we're essentially the same (vf series turbo, up, exhaust, TMIC) I have an intake, but that shouldn't make that big a difference, it is an SPT.
I'd love to, but I already flashed my FXT ECU with an 04 STI base rom. I would either have to flash back to an FXT rom and then upload your map, or just pickup/create/borrow an STi tuned map.

Now this sounds like fun! I need to see if the poor thing even starts... I haven't moved it since before the wedding. :oops:

Holy :censor: !!! What the :censor: !!! Really?!?! That lean at the ol/cl crossover?? That's really messed up.

Don't worry about it. I was hoping the same thing. Or at the VERY least whatever was wrong would be covered under the warranty.

Ah, well. At this price point it doesn't make sense to replace the stock motor with a another stock motor only so it can break on me within the following year. So, I'll call up AR Fab, and see what options they can give me. In the meantime, the car will remain parked except for business I can't handle on the bike (i.e. carrying large items) until I can save up the fundage to get it fixed. I could put the repairs on a card but I would REALLY rather not do that.

Woh, how did you swing that? I thought the '04 XT ECU was 16bit and the '04 STi ECU w/ 32bit? A lot more tables and info...or did you just borrow the info from certain tables and just replace that?

Nope, as I said... I flashed the entire STi ECU rom over to my FXT ECU. Julian and Darrin were with me when I did it. I now get to enjoy the benefits of the increased resolution of the STi ecu. Very happy about it too... especially regarding the transitions between ol/cl and lower boost vs tps %.

Basically all the crap that everyone talked on openecu and the like was just in fact that - crap. You absolutely can flash the STi rom in its entirety over to the FXT ECU. Or at least you can with the 04's. Hook up a tactrix to my ECU, turn the key, read the rom and it presents itself as an 04usdm sti (can't remember the exact ecu revision number at the moment).

I might be able to get this fixed under warranty. I talked to SOA (finally) and they told me that should be covered barring I don't have serious engine mods (which all I have is an intake) and that I been using the right gas (I only use 93). I'll drop it of at Don Beyer again tomorrow and see what happens. Also, my ABS light is on. FML

What about the Utec? And the flash? Can you revert either?

You have:
A Utec
A Flashed ECU
An Intake (non-Subaru)
A Turobback (non-Subaru).
ANY of the above could be used against you.

I would yank the Utec off in a hurry, remove the MBC (if you are running it) and flash it back to stock asap. If you have the stock exhust, I'd put that back on there too. The Intake they have already noted, so no sense in ripping that out.

The ABS light could mean a couple of things...

So it sounds basically like I'm still screwed. Because I can A) try to take the car back to stock and hope that they'll fixed it. If and when they don't, I still won't have a car I can use. Even in the off chance that they do, I'll have to put everything back. B) Keep trying to save so I can spend $4000-$6000 for a new engine, gaskets, and install. C) Park it somewhere seedy, hope it gets stolen, and collect the insurance.

Yeah the ABS light could be a number of things. But with my string of luck with this car, whatever it is will cost me at least another $2000.

All the stuff above can be taken off in a couple of hours... seems like it's worth the trouble!

Seriously, let's find a day and a group and let's pull everything off. I'd be happy to help. I still have a functioning Tactrix cable.

Cool, if y'all think we can get this done. Maybe it'll even be worth the effort. Let's see if we can't get something arranged.

With the exception of my front brakes and front grille I have held on to every stock part I have ever removed (and the list is pretty long).
Yours is a shinning example of why i do.

Talking to Chuck, or talking to me?

If you were talking to me, then give me the brake pad clips back...

Okay I talked with Monster Truck Matt (MTM), Sabre, and a few others at the meet last night about taking the car back to stock. I want to try to get this thing back to stock as soon as possible before this this car goes completely to :censor: .

If anyone wants to come out and help turn wrenches, it'll be during the week at MTM's place since he's not available on weekends. The exact day is still TBD but, more than likely, it'll be early next week.
