So, I sent Osiris an ecu dump on October 8...and finally sent this today- after sending a couple emails in between....
"How's it going? I sent the ecu dump on Oct. 8....as I am barely driving the car due to the weather near Chicago this time of year I am not in any real hurry. If you are adding support for my year that is great and I'm happy to wait - if not though then a refund would be nice so I can explore other options. "
....and I received this reply
"It should be released later this afternoon. It is in the final stages of testing."
BTW I did check and I have a silver ecu so it should be looking good for alot of people!!

Sorry for the delay - they were doing bench testing, but I received this yesterday:
"Attached are the Osiris and Back to Stock ROMs for AM604, an update for AM603.* Please let me know if you have any difficulties with the flashing process.
-Chris"
I have to swap pins and then load the rom - it was too cold in my garage last night(or should I say I was too burnt up from Thanksgiving to go out and turn the heater on)....but I will get to it tomorrow morning and post the results!
Not sure if they are working on am603 as well but am604 is a go!

Alright, first off I have to say that I DO have an am603. I was mistaken. Today I did the CAN pin swap and then flashed the am604 OSIRIS patch onto my ecu. It took it as it was supposed to, but upon starting my car it threw multiple codes and was basically in limp. I emailed Chris @UpRev and he advised I go back to the base ROM, which fixed everything.
"Do not try flashing again at this point. I will look into the patch and see if there is anything I can determine given the error codes and car behavior.
This is similar to the issues that we were having on a previous attempt at patching the vehicle. It was first patched several years ago without success by my predecessor. I wanted to give it another try using newer techniques. The issue stems from the vehicle having an older style ECU that is different from other 2003 G35's.
Hopefully previous data and your diagnostics will yield some results."
So apparently they have a new team working on this. I offered to help in any way and he asked me to do live data logging with the Osiris ROM. Unfortunately my ecu crashed while uploading. If I can't recover it I will have to send it in or get a new one.....ugggh.
Anyways, at least there is some light out there for anyone still interested. I'll keep ya posted.

I guess 604 is an update to 603..neither of them are supported at this point. I didn't find that out until after I bought Osiris. I thought I was fine as I don't have a doggy door...but alas I was wrong. Anyways, I got lucky as I am now the guinea pig lol. There are others on here that have been waiting for years.
