There in part is the reason why you are getting so many different ROM Headers, as I thought it is corresponding with the actual PCM Assembly fitted at the time of production, as I said there are over 58 changes to the 03 RX-8 for UK, Australia for manual and Auto's, 5 and six speed.

I can't confirm what you are seeing for your US Spec cars as the PCM is again Different, and perhaps for what ever reason there has been less changes to the US spec cars?
I don't have the US EPC.

I have one on my other Desktop though in PDF form...

ASH8

Just to add MM, if you have any future issues with AccessPort or want to know EXACTLY which PCM Assembly is fitted to a particular car here in Australia, all I need is its VIN, the EPC then sorts the exact unit installed, an N3Z6 or N3R6, etc.

Or I could go an manually list all 70 odd PCM units by Chassis Number manually and show the point of change by VIN.

BTW: If any RX-8 Owner wants to know what PCM they have in their car, locate it, look for a paper lable of the actual Alha/Number Part Number stamped on the outside case of the PCM.

So ash8 u mean cobb can be use for our aus r3 model but not the us r3 model ?

ASH8

/\ NO, there will be and never has been a Cobb AP for the 2009~ Series 2 RX-8..

Either the R3 or GT or Luxury, they all have the same engine and drive train and electrics.

And NO a Series 1 Cobb AP will not work on a Series 2.

MM, I checked my ecu code, N3J6 18 881F, what does this mean for tuning with the COBB? Is that compatible?

MazdaManiac

iTrader: (3)

Is that a 2004? (I believe it is since the N3J6 ROM has come up before.)

If so, it is NOT compatible.

Only 2005 and up HiPower models are compatible.

Giustino

iTrader: (2)

So this is no longer valid?

is there any information as to why the 2004 are not compatible? is it the devil at work? or something a little more realistic?

ASH8

Try this # N3Z6-18-881G

It is the OEM Replacement Part # For a Aussies 6 Port 6 Speed of late 04 to early 05 production , including your 8.

The actual # on your original PCM may not be accurate for earlier S1 Aussie RX-8's..
In fact N3J6 18 881F does not exist on latest Mazda Aussie EPC for S1's.

You are the second person I have had today with this same N3J6 PCM, it appears Mazda did some changes at some stage or there was/is not a direct cross reference with their EPC's which is VERY unusual...but can happen.

I know on my S2 PCM the part number on it is the exact same # as EPC.

Giustino

iTrader: (2)

so the N3J6 18 881F v N3Z6-18-881G difference means what? should my ecu have been replaced by this?
Or is N3J6 18 881F the number on the physical PCM shell and you are saying N3Z6-18-881G is what my ecu should be?

ASH8

You PMed me asking where you could find the ECU Part Number on your cars ECU, I told you to look on your ECU itself.

It appears this information (at least for Australia) may not be correct for earlier made RX-8's...it IS correct for current Mazda's and Series II RX-8.

If you went into a Mazda Dealer today to order a replacement and new OEM ECU the part Number is N3Z6-18-881G....you could be supplied with an E F or a J.

N3Z6-18-881L Came in from November 1st 2006 Production and is not interchangeable with any earlier ECU's.

As I said the N3J6 Does not actually exist as a reference for a new OEM replacement ECU.

"Should my ECU be replaced by this", only if you required or needed a brand new one purchased in Oz...please don't get the idea you have the wrong ECU in you car, that would be unwise.

And No, as I said "normally" the Part Number on the outside of ANY Fitted OEM Part IF it is shown is usually the Part Number for a replacement part...but not always.

EDIT: For 6 port, 6 Speed Manual, S1 Australian Spec only.

ASH8

PM me your VIN (JM0FE1031........) and I will tell you exactly which ECU the factory says you have as a replacement #.

Giustino

iTrader: (2)

Great info thanks ash!
I will PM you the VIN when i get home tonight.

auzoom

Giustino, I have bought the AccessPort for AUDM models and it worked with the N3J6 ECU that I have.

EDIT: I do recall that I had to send a ROM Dump to MM before it worked with an update to the AP but in the end it did work.

Well, like it says in the first post -
It will work on 2005 and up 6-port (HiPower) manual transmission equipped models.
Pretty straightforward.

auzoom

Ummm no...N3J6 is what my car is, its a DEC 2004 built MY05 so somewhere along the lines YOU have confused the topic.

Not so straightforward once you made the comment:

Plus ... we don't have "HiPower" models here, never have.

If you want, I can remove my post that was clearly trying to help someone TOWARDS a sale for you. But if you're that well off just let me know and its gone.

MazdaManiac

Which means it is a 2005.
That is how it works - Model Year. You said it yourself.
For instance, my RX-8 was built in May of 2003. Does that make it a 2003 RX-8? Of course not. There is no such thing as a 2003 RX-8.

That wasn't a comment, it was a question.


So, you don't have 6-port models there? Interesting.
I'm sure some people might be surprised to learn that.

ASH8

Yep...for Australia.

ALL Series 1 Manuals were 6 speed and 6 port (High Power).
ALL Series 1 Auto were 4 Speed 4 port (Standard Power).

ALL S2's are 6 Speed, Manual or Auto 6 port (High Power).

Naturally, different ECU's for all Auto's and Manual Transmissions.

It appears at some stage Mazda's branding of originally installed at factory ECU's 'may' of actually matched for the replacement Part#, just not sure exactly when for S1.

Basically 3 Model Code iterations for Australian ECU's, BUT many "end letter" iterations from plain number to A to L and in-between...but a total of 4 ECU's for S1, 1 for Auto's and 3 for Manuals.

Depending on VIN/Production Year, all of the A-K's supersede one way ONLY, new for old.
The two in bold (E and F) will fit either way.

These are the EPC P# Model Codes for ALL Australian S1 PCM as a new OEM replacement.

Auto's N3Z5-18-881, 881A,B,C,D,E,F,G,J,K for ALL 4 speed S1 Auto's.
Manual N3L9-18-881, 881A.
Manual N3Z6-18-881, 881A,B,C,D,(E and F Either Way),G,J.
Manual N3Z6-18-881L is not interchangeable with any from Nov 1st, 2006 Production till last of S1 Manuals.

Waiting to hear back on last or latest available complete ECU P# for S1's.

Finally some good info for the AUDM ecu in the one place! Thanks Andrew and ash and...MM (still haven't clarified the question of what makes the 04 so different? and why it cant have the ecu dumped to make it compatible?)

Mine is a Feb 2004 build, not sure if it is MY04 or MY05. I assume MY04

Will email my VIN to ash to find out

ASH8

N3Z6-18-881D which supers all the way to a J...or N3Z6-18-881J
The J was/is used UP TO Nov 1st, 2006 Production.

Still waiting for confirmation, but I am 99.9% positive if you went to a Mazda Parts Dealer here you will be supplied with a N3Z6-18-881J PCM, unless Mazda have updated or changed P# since July, 2011, which I doubt it (Or still has stocks of earlier ECU's below the J)....Also keep in mind any brand new PCM must be initialized or flashed or programmed with the Mazda Dealer Service Departments MMDS PC.

At this stage a Mazda Dealer here is the only one who can do so, we are one of the few western countries which does not permit manufacturers software being released to Independent Operators, like in the US or Europe.

Motor Industry is lobbying Federal Government this month to try and force Manufacturers to release this information...as a pay to view/use like Mazda US and Mazda Europe.

auzoom

Seriously...are you for real!!!

I am well aware of what it means, hence, as you said, I said that my car was MY05. I was kindly pointing out to someone what YOU had left out ... a) that your "2005" comment refered to MY05 and b) that the N3J6 ECU belongs to an MY05 AUDM RX-8. AS I said earlier, apologies if I helped you out

Yep, got that part. You said that you believed it was a 2004 based on the ECU designation N3J6. Its wrong and it added some confusion as can be seen by giustono's post following yours continuing on his concerns that 2004 model cars aren't supported.

Where did I say we didnt have 6-port models? I said we dont have "HiPower" models. All our MT cars are 6-port. I was making another point about the fact that your so called clear statement wasn't so clear. We dont use the designation of "HiPower" here because its redundant. Walk into a dealer and ask for a "HiPower" model and they will give you an even more blank stare than if you ask them how a rotary engine works. Some will understand what it means, its not what I would call clear.

auzoom

Ash, I reckon you are correct that the N3J6 is superceded by the N3Z6.

I am not understanding how you felt this was not clear.
When you ask someone "What year is your Nissan Altima", they don't launch into a pedantic tirade about build dates. They'll simply state the model year.

Well, as you have found out in subsequent postings, it isn't wrong.


Andrew - how many RX-8s have you tuned in Australia? How many have you even had contact with?
Are you not aware that your market is absolutely saturated with JDM and European models?
"HiPower" and "LoPower" are designations directly from Hiroshima. It is a relevant distinction for all markets, but especially yours because of the sheer number of grey-market cars.
I've had to refund quite a few Australian purchases because the owners had - sometimes unwittingly - purchased grey-market cars that they believed were AUDM models.
At least two were 4-port, 5-speed cars - i.e. LoPower MTs.

This is an AccessPORT thread. The language is constructed so that people that are interested in the AccessPORT will be properly guided in their purchase.

auzoom

I'm on my phone so going to keep this simple.

You said yourself that "HiPower" = 6-Port. We don't have AUDM 4-Port MT MY05 or above. And Ash can correct this but I am pretty sure we don't have them AT ALL. This is my point...you responded to my post to someone else which gave them valid information to assist them in a decision on whether to purchase an AP. You responded to it with a post that added no value and was only attempting to make you feel good about yourself. It's as ridiculous as your statement of "how many RX8's have I had contact with". I am not getting into a **** fight with about that because as youalways love to point out to people, the answer is readily available.

If you want to add something useful, state categorically that the N3J6 ECU is not compatible!

auzoom

PS If I ask most people what year their car is, the reponse I get is "It was built XXXX".

Perhaps MM is getting NZ and Aussie mixed up here ? Two different countries MM

NZ has a saturation of JDM rx8's because we get a huge % of our cars from there ... USED .
Australia , because they have their own car manufacturing industry.......doesn't .
