yea that is nice to have. the dealer near me wanted my car out because they said they don't deal with swaps or conversions and it could be bad for the company or something. kinda lame, but the independent shop is free for programming and subaru was going to charge 60 dollars to program

also depending on how much of the drive train you have you dont want to use a cpu older than a 06' or you wont be able to ustlise the yaws system. yaws make it handle like a kitten.

Ok so i don't have the steering column or hubs so i'm not sure what i'm going to do for dccd yet. Im assuming i can run in manual mode at least. Also i will be using v8 sti hubs but i have not sourced abs sensors yet. I'm trying to find some used ones so it doesn't cost me an arm and a leg.

So if i use an 07 ecu and matching key from another car will that help with me not having a matching key for my current ecu?

for the auto dccd you dont need the steering column but you do for yaws. also its time consuming but since you have the drve train you should also put in the entire wiring harness. then you can have your auto dccd. i should have a streeing column, abs sensors and a wiring harness

the info was posted in the thread what you need to make it happen... ecu, immobilizer, keyring, and key.
which components do you have, are you missing any?
if you have all the components, are they all from the same car? if so they should all match and you're good to go. if they're not, you'll need a solution to reprogram them like what was being discussed with the SSM3.

well i can get you the parts you dont have but i did find this out, almost any professional key smith can come to your house and reprogram the immobilizer, key and ecu. in fact the guy(Alex) can reprogram a key that doesnt even go to that make/model of vehicle. i was amazed that i never looked into this before but i never needed to. so make a list of parts you dont have ( i think you sent them to me already) and i can gather them up and send them out after you call around and find a key smith equipped to program ssm3. REMEMBER if you bout the 07 drive train do your best to get all parts 06+ so you can have the yaws system , its so much more fun! but you will need the steering column. i have a 07 limited steering column i think, ill have to check(not necessary to have right now, but you love it when its all together.)

I need a key and the antenna receiver thing that goes on the steering column.

As far as the other stuff goes i don't have the steering column, so no yaw sensors. I didn't get hubs so i went and bought some v7 hubs so i could keep 5x100. No abs sensors for those at this point and i'm not sure if the axles will even match up yet.

So as far as dccd i'm guessing i'm only going to be able to run it in manual mode.

Anyone with 07 parts that could help in my process would be appreciated.

i think you already know, but I was told this last night as a way to get around the immobilizer, not so cheap though
if you can use an 04 sti ecu and then bring the car to a good shop and they can tune the car for you so that the ecu will work with the car correctly, otherwise it runs like crap. however, you would also have to pick up an accessport, so it would not be the cheapest way to go

i dont see how that would work? so plug in 07 ecu and just get a tune? i was thinking the 07 ecu was way more advanced.

salvator_rizzo i know your in this thread but for other people there is some more info here. still no 100% certain solution.

Hi guys, I stumbled across this thread while searching on a solution to a similar problem with my GDA.

I recently purchased an EJ207 with ECU & Loom to replace my EJ205 and needed to get the loom modified to support AVCS. The wiring had all been done (not by me) before the engine went in just so they had room while working. The engine is now in and everything is wired up but the fuel pump won't prime and I think it's because of the immobilizer.

The ignition comes on but the CEL doesn't and I also noticed the ignition barrel isn't lighting up.

The engine is apparently from a Spec C (Version 7) and is also apparently JDM and I thought the JDM ECU's didn't have a factory immobilizer.

Can someone confirm this for me please?

I also bought some STi keys (without the CDL buttons or chip) which I intend on using but cannot afford to go with an aftermarket ECU just yet.

The car is booked in with the guys who modded the loom but it could be some time before I get it back and I wanted to see if I could save time and do it myself.

This could be a wiring issue and nothing to do with an immobilizer (if it even has one) so just looking for some ansers/opinions.

Thanks!

why didnt you just source a key, ecu and immobilizer unit and then have them all reprogrammed at a dealer?

im pretty sure that the ECU simply receives a yes or no signal from the immobilizer... so the only 2 components that need to be synced is the key and immobilizer.

I am in las vegas twice a year not to mention I have an aunt who lives in henderson. I could have flown down with my SSM3 and reprogrammed the whole system for you provided the wiring was right. The next time I will be down in vegas is for Sema. That is if you want to do the same swap.

Thanks, but when i was in the process of doing this swap I still lived in northern IL. I just moved out to Henderson last July.

Reason I am asking here as I thought it may be a similar fix to the GC8 where you just have to swap a couple of wires and relocate a pin on one of the plugs.

Hopefully it can be done though, I hate to think they'll ring me and say "Ummm, we can't do it, you'll have to buy an aftermarket ECU" Not an expense I can front right now.

It will plug in with no problems but it won't run. IIRC six wires need to be moved around. The 04 ECU also has less memory than the 05+ (not that it's been an issue so far)

Not true. The only way to change the immobilizer on an MY06+ STI is with a Subaru Select Monitor V3.

well if its not true in your area that sucks for you. up here in portland, or getting a mobile service to reprogram the key is as easy as calling for pizza. i HAVE had this done 3 different occasions. cut on the spot and programmed after. no dealerships needed.

were planning on using the 04 sti ecu in a buddies swap.

does anyone have access to 04 and 05 sti ecu pinouts?

i have heard that 6 wires are in different locations.
