Finally got the new setup to the dragstrip.

04-WRX 5 speed
v9 EJ207-stock everything including the downpipe, tuned by Stephen Clark @ iatuning
5 spd-Exedy OEM clutch

13.695 @ 105.58
2.07 60ft
8.88 1/8th mile

That was my best pass of the night only got 4 passes in. Gotta get that 60ft down. Launching the 207 is slightly different than my 255 was. Needs a little extra clutch slip to keep from bogging. 60ft started at 2.35 worked it down to 2.07. Blipped redline at the top of second gear barely but enough to kill some time. I feel like the car has a 13.3 in it with a good 60ft and better shifting, maybe even slightly better. Laptop shut down on me, couldn't adjust launch control so it stayed set at 4500 all night.

Overall pretty satisfied. First trip to the track in this car and with this motor. No hiccups no knocking. Taking it out for another trip next week with the same setup before i start throwing some parts at it

Once i get some time it'll get up to Pitt Race's road course but the 1/4 is still where i like to play the most. Posted more as a baseline for the 207 guys without a dyno like myself to show what they should be doing in stock fashion. 106mph equates to right around 300hp on the factory downpipe, bcs, and intake. I've seen a lot of "stage 2" 207s in the 14s and always wondered if thats just what they did in stock fashion

1/4 mile is the best representation of what a car is capable of. granted road courses might be more fun, but every course is different. 1/4 mile doesnt change.

also im rather biased lol

my goal is to break the stock 207 record of 11.56

225/45 x 17 is a standard size tire. No way that tire alone flagged you.
What size wheel? If you have an overly wide wheel, that might cause you to be flagged because the tire would be stretched too wide on the wheel, as D-Rodman mentioned.

If this worked 2 years ago, with the same wheel and tire, then it shouldn't be an issue today UNLESS the tech 2 years ago was an idiot or the one this time is.

EJ207s don't have TGVs. This should not be an issue.
Exactly what motor are you running again? You never said and I'm not going to presume what you have just because of the thread we are in.

Wheels are 17" and was told by the tech I was flagged for low profile tires, I am gonna go with idiocy. Engine is an ej207 v7 so I need to source some tgvs and an usdm engine wiring harness to pass this inspection.

Generally tgvs don't matter but if they find any type of circumvention of the emissions protocols, I would fail again.

You need a usdm ecu to run your motor, no need for anything else. The low profile tire flag is strange unless your tires donít fit the wheel properly.

Thanks for everyone's input, I think I know what needs to be done to pass this inspection.

And as it turns out, you do need a usdm engine harness to run the TGVs.

I wasn't able find good information so I'm going to go ahead and post this. My EJ207 "V9" Spec C came with an apparently immobilized ECU (22611AJ810; no test connector activity; no fuel prime; cranks won't start; etc.) The importer is offering a replacement ECU from a JDM EJ205 w/ AVCS. Is this an advisable way to run this motor? I am new to tuning, but as far as I can tell some of the tables are sized differently (smaller) on the 205 ROM which leads me to think it will not be as tunable. Can anyone confirm this and/or share an example where this scenario worked out?

Send a message to Stephen Clark at IA Tuning, he can give you an answer you can rely on. He might be able to send you a stock rom to flash that wrx ecu in order to run that motor.

yes its fine. as long as its a 16bit ecu with avcs control it will work.

i have a jdm 205 forester ecu running my ej207 and it works fine.

custom tuning is needed of course.

I've done a fair amount of research and I can't quite figure this out.

What am I trying to do? Choose the best starting point ROM for my swap so I can start tuning. To me this would be the ROM this engine had, EJ207 "V9" Spec C (2006 is best guess by date code from VF36). This is in a 2004 USDM WRX with the original 5 speed.

As previously mentioned I was provided an EJ205 ECU (probably 01/02 JDM Forester Turbo based on stock ROM A4RI200I; there was no sticker). Thanks for the replies and especially Stephen Clark for confirming this would work.

Looking at the stock ROMs I can find for the Spec C:

A4TJ121C - seems to be Spec C, but probably 2006 based on some info I've seen even though Romraider forums have it as a 2005.

A4TJ111C - Seems to be Spec C 2005

These two ROMs differ only by 7 tables, but...

When I tried 121C I found my NPS reversed (1 in gear, 0 in neutral) and the engine would prime pump, crank, but not start. I assumed this was the NPS not really thinking about it, but I couldn't find the right hex address anywhere to "flip" the NPS behavior.

So I tried the 111C thinking this 2005 "V8" would have right NPS behavior. Wrong, NPS is still 1 in gear, 0 in neutral. However, the engine will start with this ROM. I haven't driven the car with it yet.

So questions in no particular order:

Is the hex address of the NPS known for the 111C ROM? BTW, It does not appear to be the same as the latest I could find which was for the "V7". Meaning the byte at that offset does not match what is expected.

Why would the earlier ROM start my car and the later, but very similar ROM not start it?

Am I being to specific trying to get one of these to work and just fall back to an earlier ROM? Suggestions on which?

I recently acquired a V8 Spec-C ECU (22611AH591) and V9 Type RA ECU (22611AJ820). Neither of these ECUs are immobilized. Does anyone know if they offer additional functionality over the standard Version 8 ECU? All I have found so far is that the V9 allows the MAF to be scaled up to 400g/s...

The best ROM is the Carberry, which is a derivative of the Group N ROM. It'll flash to specific year/model ECU's and do Flexfuel mapping with the appropriate hardware.

I thought I would post an update to answer some of my own questions and provide updated information.

First off the A4TJ111C ROM did not run well in the idle to 3K RPM range (side note this was w/o AVCS) so I fell back to A4TE002Q (2003 STi) which did not need an NPS invert. A4TE002Q ran great and once AVCS was enabled it was even better. I ran that for a couple of weeks until I found this thread about the NPS invert bit for the A4TJ111C/A4TJ121C ROM:

http://www.romraider.com/forum/viewt...p?f=15&t=12323

I can confirm this works. Tested with both ROMS.

However, A4TJ121C is still a cranks won't start.

A4TJ111C starts and runs fine with some limited testing. Better than before so maybe NPS invert or maybe AVCS solved that issue.

Since there is only 7 tables different between these ROMs I am going to go ahead and continue with A4TJ111C, but it bugs me that the other will not start the engine.

I do plan on running Carberry eventually as my goal is flex fuel, but I just don't think that is the place to start for a novice tuner.

it is not difficult to search and build a collection of stock roms. I managed couple years ago to download all roms of interest to me. I don't just post them here because I rarely have in front of me that lap top anymore..

I totally agree, the ROMs are out there. It's just that the information about what they are is less than perfect. Having identified the 22611AJ820 as my target hardware (good luck with that), I would like to know which ROM I have matches what was stock on that ECU.

I had a thought, but I don't know enough about the subject to not take the chance of sounding silly here, but I'm considering the later ROM, A4TJ121C, is from a later immobilized ECU like 22611AL380. Maybe this prevents it from actually running the engine regardless of what hardware it is on. That being said, when I had an ECU I assumed was immobilized, 22611AJ810, it would not prime the fuel pump at key on. Otherwise behavior was the same, cranks won't start.

I'm happy now with using the A4TJ111C ROM with the 7 tables updated as a starting point. A little more road testing has demonstrated it runs well.

Thanks all. I don't know if I have said it yet or not, but I could not have taken on this project with out this ridiculous thread and the people that still visit here. I have a lot to contribute back once I get some time to pull it together.

my lap top is not on my network. Let me see what i have on my NAS.
So my ECU runs native on A4TJ111C.
Your question is what's the ECU part number that goes with it, so you can associate it with a car? I think that list is on the romraider page.

As far as the rest, when I temporarily use my WRX ECU, it does run like crap till 3000 rpm and while I still had my 5 speed, I had to invert the neutral position for my 2002 WRX gearbox, which I did mechanically, by replacing the switch.
Now, while the engine runs great, it's inverse to the 2002 WRX ECU, so no mistery there..

Your problem with the later immobilized rom not priming can be because they physically swapped two pins in the pinout, for the fuel pump. So you'd have to repin those in your car's wiring harness in order to prime the pump and fuel the engine, if somehow you eliminated the imobillizer..

Now as far as the Rom is concerned, whether the physical pins of the ECU have digitally atributed ports in the ROM, so therefore the rom re-tasks your pins of the ECU per a 2006-2007 pinout with fuel pump wired at a different pin? I'm not an electronics engineer, but maybe?

What i'm trying to say is: If the rom can flip the physical assignment of the NPS from normally closed to normally open, maybe it can flip the assignment of the fuel pump from normally pins 2 and 3 to normally pins 4 and 5 (as a fictional example) and because your harness still has them at 2 and 3, you can't prime and fuel.

Let me clarify that I can say for a fact that the pin assignments for the fuel pump are different between immobilized and non imobilized EJ207 in the GD body, because I have the factory wiring manual and it indicates this there. But I'm as lazy as the next guy and don't feel like finding the book and posting the exact pins for both cases. But this much is not a theory.

hey guys I need a bit of help,

Im planning to swap an EJ207 V9 in an 08 Chassis. Though everyone im coming across which has done this is doing it on an older chassis.

I found a dream deal of a chassis with a blown motor and quite keen to get it, with my budget and everything sorted out.

Is this a doable swap/project? Or will i run into too many roadblocks doing so on a newer model?

Find a 207 with dual avcs. So V10 and up.

I agree, they are expensive though but there aren't too many out there that haven't done this swap.. I personally would run the 08+ STI ecu and run a cobb with it
