NOTanEVO,
As far as I know your ECU will be jdm stock map, unless the previous jdm owner changed it, none of the imports give a damn about what map is on there.

I would highly recommend staying out of boost until you have the car tuned, you are flirting with blowing your brand new motor by running wot on the jdm tune. This is rehashed several times in this thread and backed with stories of blown engines because people thought it wouldn't hurt (and it may not, but without logging you simply don't know.)

Stay out of boost until you get a tune.

....So I'm following the DS1 procedure for wiring my AVCS, and I notice that the Subaru schematic shows B84 pin 10 as Blue/Yellow, and pin 11 as Blue, but the DS1 instructions say opposite. My car is wired as the OEM manual states.

I'd hate to get the polarity wrong

That also may be why some aren't having immediate success.

HTH,

S.

While people should, and do, get tunes even on their stock USDM Sti, for the safety of not having knock, this business of JDM fuel as a need for tune is really not based on any fuel-related facts in areas where you can fuel 93.
And this, based on the documents, we can agree on.

This does not mean that you can transfer your mods and run on the stock tune, or that you can fuel it with 91 on factory tune, or that you can run it with an USDM ECU and no tune, or, etc, etc.

Also, fastnyopi, finding the truth only derails misconceptions.

Getting the polarity wrong just means you have to reverse it. It doesn't do any damage. I've done this a few times Generally, I don't even bother with the wiring in the car, I just grab some shielded wire and run it through the firewall. Though re-purposing the TGV wires saves a bunch of time, the other stuff just seems to take longer.

No you wouldnt really be able to hear it. Get a tactrix read up on open source tuning or just really wait for STI Mikeys tune. Gonna need a wideband too. Ive seen the Knock issue Clark has talked about and would'nt be surprised if you havent knocked your IAM down a few points even with one mildy hard pull untuned.The JDM map is very aggressive.

hypothetically if i did knock my IAM down a little, can issues like that be corrected through tune

shyt im freaking out now: sorry for my bitching i had no clue though, guy at jspec misinformed me. Jeez i hope my motor is still ok

This is a little off-topic but I was wondering if anyone here is running a Ver. 8 207 with an SPT 3" cat back exhaust or an Invidia 3" Q300 cat back exhaust. I currently have an HKS Hi-power and it is way too loud. I installed a hi flow cat in the system but it is still too loud for my taste. I was wondering which system out of the SPT and the Invidia would have the most power but be the most quiet?

Thanks

I would say the spt would be quieter but they are droney.I wasn't a big fan of my spt. I would go with a borla hush or the q300. I have a v7 motor but no matter what motor its on these are the quieter catbacks.

Borla hush sounds nice, i'm just not a fan of the twin tip look. Also consider the
Greddy Evo 2 if you want quieter

Thanks. I haven't even looked at the Greddy evo 2, I'll have to check it out. Is changing the cat-back exhaust something that will require a re-tune?

Thanks

I have the evo2 on my 205, yes the 207 will sound slightly different but I love the sound of it. Not loud by any means but you can tell it is not stock.

Generally changing the cat back alone will not require a retune.

NOT,
You are probably just fine.
Your IAM is variable and will be taken care of when you are tune.

Don't freak out, just take it easy until you get tuned.

Did any of you with a v8 swap into a Bugeye have to modify the Front O2 connector (B18) to fit the v8 stock O2? My connector does not fit either the USDM STi O2 or the JDM v8 O2

Also think I got the wrong radiator, or at least the fans...the fans on the v8 radiator have a 4 pole connector on each side, and the Bugeye (and JDM STi) uses 3 pin flat connectors.

So much for plug ang play

I just had a EJ207 v9 Spec-C swap done and I got the KillerB oil pan/pickup/baffle installed. However, it seems to be rubbing against the header. Anyone else have this problem/know a solution?

Simple fix.......remove heatshields and wrap the headers.

No, you shouldn't have to change anything like that. Something isn't right.

You have the older Legacy style fan connectors it sounds like.
