I have a question about rom Ids. Of the Evo Xs that I have tuned, there are two main rom ids on the GSR.

1. The 82680017. This is the rom w/o the factory re-flash.
2. The 82680020. Thsi is the rom w/the factory re-flash.

Can I flash the 82680020 on a car that has the 82680017? Will the car start? I believe that I can, but I want confirmation from someone who has done it.

Bryan are you out there

 

The immobilizer is not part of the rom like the 8/9

 

Works without any problems, the immobilizer seems to be in a sub ROM.

 

There are ocasions where it will not work .. and or it works but the car drives funny ..
Just let you know there's cases I've experienced ..

Once reverted back to standard ROM it was ok ..

 

Where can I download all versions of stock ROMs?

 

I believe you may mean 52680017 and 52680020

 

Is there some news about this?
I have ROM 52680017 and I'd like to flash ROM 52680020 that is the last factory reflash (I want to use that as starting point to tune some tables and make some comparative tests).
Do you think it will work or not?

Thanks guys...

 

Should work fine. Without a problem.
