Do you have a stock ROM to test against? If so, try flashing that one on to see what happens. Also, are you getting any SES codes? There are two things I can think of off hand that cause a constant rich mixture which are a bad O2 sensor or a bad set of values on the 'Airflow/Hz Baro and Air Temp Compensation' table. I've never seen a ROM that was unable to revert back to its original settings upon a flash of a previous version. That's a strange one.
This sounds like you might have had a power problem (low battery, for example). I don't suspect this was due to the ROM you picked; more of a physical condition, from your description. (The fact that you had trouble flashing 9055 afterwards, and that the flash failed part-way through, suggests to me that you never actually got a successful flash at all.) USDM VIII ECUs are 4-plug; there's very little difference, other than the actual plug, between the USDM and JDM ECUs.
why bother when we have 90550001 maybe that can be the universal rom
It possibly could be, except for the level of effort that's already been spent on 96530006. Does 9055 support ICS? ACD? (Although, to be fair, I don't think anyone's gone to the trouble of running through the code associated with the line from the ACD to the ECU, have they? Acamus/mrfred/merlin?) Front and rear O2?
I'm not married to a particular version (although there's a few good points in 9653's favor from a code perspective), but I wouldn't want to see the effort that many people have already put into 9653 conversion issues, documentation, and coding wasted in a switch away from it without there being a substantial benefit, and without understanding what hardware support (if any) we'd be losing.
Basically, what I guess I'm asking is: is anyone who currently runs 9055 willing to give 9653 an honest try? todd6027, BarryC, cossie1? I'm offering any help I might be able to provide, and I'll do my best to coerce anyone else I think might be able to help into assisting.
It's entirely possible that we won't get it working, but I'd like to know why it won't work, since knowing the why means we might be able to fix it.

Even though 9055 worked perfectly well on my car it was always much slower even after some tuning, it just never felt like you had a crisp throttle. It is also missing some things that might cause some issues with people who need to pass emissions.

It's entirely possible that we won't get it working, but I'd like to know why it won't work, since knowing the why means we might be able to fix it.I am running 90550001 Tephra V5.7 with SD in my 1.6 NA Colt, the definition I have for this rom is probably as advanced as 9653 and this is the rom I use for all my tuning or early evo conversions I have never had an ecu flash fail with this rom thats why so many of us over this side of the pond use it,
I will try again to flash 9653 tomorrow and post up the ecuflash result But I am fairly confident it wont accept it
and yep 9055 has ICS everything it is a JDM Ralliart rom but would not have all the emissions stuff required for USDM Evo's

Now as for testing the roms, I have already tried 96530006 in stock form (before the tephra mods started), when I first did the ecu conversion on my Evo 6 RS2.
It was over 2 yr's ago now, so no datalogs and tbh my memory is a little hazy, but I spent a few hours just trying to get the car to fire up and then run smoothly (like it did on 90550001) and it wouldn't have it.
The reason I tried swapping the roms around at the time was because I wanted launch control and the Evo 7 ecu wouldn't give it me on any Evo 7 rom.
Anyway iirc I had to swap pins 8 and 22 around just to get the car to start, which isn't too much of a problem, but it is a pain getting to the ecu on the earlier models
When it did start, it felt rough, as in not steady, and it wasn't any better if left for a few mins to sort itself out. I even bought an 8 260 ecu (which this rom is originally from iirc) and tried it with that Ecu, for me it was no better.
A couple of cels did come up when I was testing 8 roms (but could have been when I tested an 8MR rom).
Oh and 1 last thing, as the 8 260 ecu (99% same as the USDM) doesn't support the sas system, then we would loose the settings for the pops and bangs too (doesn't matter to me, as I can't run the sas system anymore but the guys in the uk are mad for it at the moment).
So to sum it up, if we all change from 90550001 to 96530006 we could have issue's with idle and general running, new cel's to sort out (as the 4/5/6 run very few sensors compared to the 8's), no ALS settings for pops and bangs plus anything else that hasn't been bought up yet.
That said I do know of a 6 GSR in the uk running an 8 260 ecu without issue's he is using a different rom again with good success, however when he flashed 90550001 into his ecu, he suffered with similar issue's to me with 96530006 in a 7 ecu
My car has been off the road having a full engine and turbo rebuild since feb this year, but it should be back on the road in the next month or so.
I would rather use 90550001 on it, as I am 100% confident it will work first time and everytime without issue's, but I am willing to test 96530006 again at some point.
***** seems barry and todd or more on the ball with the reply's than me tonight
wheres the program? what am i doing wrong? i try and download and when i try and open it takes me back to the same download site.
also i have the 03 usdm so i wint need to chage anything?

The front O2 is not being taken into account to calculate the mixture while in open loop. So the Airflow/Hz and Air Temp compensation is what is left, but I haven't touched those. Maybe it's something that got messed up and it happened that same day that I Tephra-flashed the ECU, but what could it be?
bucking and sputtering sounds lean rather than rich. But I assume you have a wideband and its working right.
When you did the big maps and set the scale of your injectors did everything look good?
ok so im limping through trying to understand this. so i downloaded ecuflash then i copy the program in that i guess and i have the 03' with ics switch so i guess it will be easyer for me by not needing something.
what i still dont understand at all is how do i get my tune program into my evo?

I updated the Fuel map, timing map, immobilizer code, injector scaling/voltage to be exactly (or interpolated in the case of fuel and timing maps) what they were in my previously tuned map and when I flash the tephra mod, the car can't hold idle.
It starts, but just dies. (I can keep it going by giving it gas, but takes a fair amount of pressing on the accelerator to get it to stay running). When the car was having problems, it also threw a 'speed sensor malfunction' CEL. The Tephra Mod options I have enabled (value of 1) are 'Flash CEL on Knock' and 'Enable Airflow Calcs.' The rest are zeroed.
I've also changed Periphery2 FCA bit 08 to 0 (D-VO mentioned he was having idling problems so I thought that was worth a shot) and had the same result with the car not being able to idle.
Any thoughts? Thanks in advance for the help.

i think i have a problem i cant get the tephermod rom into ecuflash i save it to desktop but then it wont come up in ecuflash if i try and unzip file the first part wont open i gives me an err only opens the second part with the words (map? air fuel? noliftshift?....that part) so how can i get this into the ecuflash program?
also if i ever want to sell my car can i put the ecu back to stock with this program?
