Hey guys, I just got my tactrix cable and I am very excited. I know I have to do a lot of reading and research and I don't mind at all. My question is, can I load a stock 05 ROM via Ecuflash w/o changing anything? I don't have any widebands yet and I can't wait to use my new tuning tools. I figure the 05 would be better to drive around than my stock 03 ROM until I can get a wide-band 02 sensor. TIA guys.

 

No I wouldnt suggest it. your stock rom you have now is fine.

 

so what, 94150015 over 94170008?

that shouldn't be a problem just make sure the 15 rom you have IS actually stock

 

I think he is talking about rom ID 96940011 05 Evo.

 

First thing to do is tell us which ROM ID you have in your ECU now, then we can tell you what your interchangeable options are

 

My ROM ID right now is 94170008

 

and u want to upgrade to which ID?

 

You need either
94170014 or 94170015. 94170015 is the latest version available. If I were you I would not subsitute any other roms!

 

+1 these are the only ones you want to upgrade to for the most part. Anything else has unknown results at this point.

 

Which one of those are the 05 stock ROM? Are all of those 05 stock ROMs?

 

You can't run a 05 rom in a 03-04.

Not sure why you think an 05 rom would be better to "drive around in" than your 03 rom.

Timing map is the same between the two. Fuel map is just *slightly* different.

 

You busted my bubble.
