Us emission laws are tighter than ours in some states, titter

Thus why I suggested an audm ej207 ecu

I was able to see and clear check engine codes on my JDM v8 ECU, but I never tried to pass smog with it. So I don't know if the Smog machine check can read everything it needs to read.

i was more referencing the compatibility of the ecu with obd2 readers. the haltech will connect to any machine in any country, but yes, emissions are a different story.

The closest ECU i could find on that page is: GDB STi B type(01.10-02.10) MT 4L 6MT207 22611AH191

So I am somewhat lost on why/how I passed and why my ecu # is different

22611AH190/191 are both for GDBB4EH and GDBB4KH (sti and prodrive models)

Do you know the difference in the STI vs the Prodrive model ECU wise? Is Prodrive model a tuned ecu from the factory or just interior & exterior upgrades?

What inexpensive code reader can you guys recommend for home use ? It must read a JDM ECU, I'm in the middle of putting a ver 7 drive train into an 05 Saabaru. I recently started the motor for the first time, noticed the fans are not turning on. Plugged the green connector plugs under the dashboard to make sure the fans are functioning and the did go on. I've been burping the cooling system, may still have air in it. Today I noticed the check engine light is on and want to pick up a code reader in order to troubleshoot whatever issue I'm having. I'd like something simple and inexpensive, thanks for the advice.

I use a Actron ODBII scanner and it's able to read my v8 ECU.

that i dont know for sure, but its probably both. the prodrive probably had a different rom from the factory. probably just minor timing and fuel adjustments. but really im just speculating. can probably dig on romraider.com to see if a different rom cal id was used.

Guarantee that the ROM itself was different, but as Titter mentioned, the adjustments were likely minor. I can't even remember if the Prodrive variant had a different turbo... if not, the engine will likely run on either ROM and you'd never tell the difference without a back-to-back dyno pull.

hi. looking for some clarification. i recently bought my 02' WRX bugeye USDM with a JDM EJ207 V8 swap. and im wondering if the V8 retained any of the other attributes that the V7 had. like the forged internals.

They are cast pistons but that engine will be perfectly fine making good power if you maintain it. Its actually a way better engine than the V7.

Hey Guys,
I just picked an EJ207 long block. I got a version 8 manifold with a few hoses on it but I have none of the fuel delivery piping, injectors, or rails. Can anyone tell me what im missing and if they have the parts, shoot me a pm? Thanks

Cheers

I can order them... but it will be new, OEM parts out of Japan, and shipping will not be cheap.

Mrsaturn, have you started reading the ej207 info thread ? All you seek to know is there, all well documented.

Installed the Full Race stock location EFR 7163 kit on my EJ207 v9 along with the Flexconverter kit for true Flexfuel operation. I'm going to use the Carberry ROM on my v8 ECU. I'll post results after the tune.

Equal length headers , twinscroll turbo , all the updated parts from the V7 Spec c and such.

Obviously not as good as say a V10 207 but better hardware and technology in the engine than the older V7.

Reliability is a crapshoot that varies car to car.

I would put a fairly sizable amount of money on knowing more about the EJ207 than the sum of the thread... if I am looking for correct info on the EJ207, NASIOC is probably the last place I will be looking.

The V7-V8-V9 are more or less the same, internally. The V7 did have forged pistons, yes... but this is hardly a reason to source a decades old motor over the newer dual AVCS EJ207.

The ancillary parts (intake, exhaust, turbo, etc.) did get better with time... but personally, I look at the EJ207 like this:

Single AVCS EJ207 (GD-series)
Dual AVCS EJ207 (GR-series, and later)

I would never define a motor by the exhaust, intake, or turbo you bolt-on to it given the tendency of importers to mix-and-match these parts all the time.

Ideally a GR Spec C or R205 / S206 would be ideal but I settled for an S204 instead.

You're not the only one.

Also, to reiterate the obvious, the v8 and v9 is a "better complete package" than the v7 for the reasons already stated. However, if one is only concerned about the short block, the v7-v9 are comparable to one another, even if the pistons are different.

Again... just a change of turbo and tune. You are not getting a motor that will be any better than a standard EJ207 (especially if you take the time to blueprint and reassemble, as you should as long as the motor is out of the car and you buy a used one).

S204 = single AVCS EJ207
R205/S206 = dual AVCS EJ207

If you can source a turbo from the R205/S206, more power to you... new sales of the replacements are still limited to R205/S206 owners, only. I've tried to source them for others on the board and it's just not possible, at the moment.
