No I don't believe so, but the stock injector sizes in the ECUs are different.

 

Any chance the ACD stuff can be disabled through periphery bits? Thus allowing a non-ACD VIII to run the ACD ECUs without problems?

I fully agree that minimizing the number of ROMs would be a very good thing to do provided they will pass the OBD-II checks.

 

acamus has posted a way to set any and all OBD tests to ready, so that should take care of that issue.

 

Has anyone ever checked 96530006 to see if it will pass emissions? If not I will check today since I am a licensed inspector.

 

^Mine is due in may, I was going to find out then...hoping to not have to use the OBD Monitor patch.

Let us know

 

I got pulled into a product build review that i wasn't expecting so i wont get to test this today. I have to get home quick and walk the dog then head out.

 

Is there anyone with a VII thats not running 90550001? If not, why? I've yet to hear of any show stopping issues. I know there's not many of us, but were vocal

It would be nice if we could have this. it will be much easier to apply rom patches. also with obd2 maybe it could incorporate the patch that was done on this thread. i have tested it on one of my friend's car and it worked flawlessly(he had his car inspected). and based on my obd checking using scantech you dont even need to give the car a drive cycle it automatically sets them to ready!

 

The car passed the OBD emissions with rear O2 sim and resistors for the heater circuit.

^Sweet, that's good to know

 

Yes, I think 90550001 should be the standard for the VII. I also use it for all the converted cars I have done -Evo 1-6, Lancer GSR etc.

 

thats good to know. now all i need to do is convence nevada to let me leave the evo ecu in my eclipse..... any chance the 9055 rom will.

if JCbanks has plans to port over speed dencety to the 9653 rom my vote would be with it for a universal evo8 rom. but for now it is with the 9055 rom.

 

Would be interesting to see if you can run any Evo 7 or 8 on 96260009, and any Evo 9 on 88570008. Both have OBD, spare ROM and RAM, run all the JDM toys, can run one or two boost solenoids, but don't throw rear O2 codes (they don't have them), no EGR, don't throw P0300 codes ever etc... The prospect of really polishing just two ROMs is very appealing.

We know that 88590015 code can run in 8857008 ECU with immobiliser disabled.

We know that 96260009 will run Euro/UK Evo 260 (4 plug ECU), JDM/UK Evo 8 (3 plug) and 8 MR (3 plug), I suspect it would also run Evo 7.

If OBD tests can be set to ready, we'd simply have the task of wrenching people away from the ROMs they know if they want features that are just too big to support across many ROMs.

Tephra 5.10 is available for both these ROMs. mrfred might not be too happy since he knows his 88590015 very well and codes well for it?

 

I have personally ran both a 90550001 and 96530006 rom in a 97140008 ecu. So far I think there is only minor wiring changes between the two, at the moment I have the 9055 rom loaded with no wiring changes and the only problem I have is that the ecu doesn’t increase idle when the AC is on.

 

Does anyone have a current and semi-complete 96260009 EcuFlash XML? I'd be happy to give it a try on my 2005 USDM VIII MR, but EcuFlash doesn't ship with a description for it (although it does have 96260007), and information about that rom seems to be very spotty. Is 0007 close enough to use as a base for 0009?

Personally, I don't care what ROMs we settle on as "standard", only that they work for everyone's hardware combination (anti-lag, ACD/AYC, ICS, dual/single BCS, passes OBD-II emissions testing, etc).

(Edit: 96260007's XML looks close enough to at least play with a bit.)
