Just received my new ROM fron the tuner; trying to write this ROM to my ECU. No problems reading the original OEM ROM, but when I open ECUflash and click on open folder, and select my new ROM, I get an "Unknown ROM" message in a box titled "setup ROM", along with 3 choices of: create from scratch, define, or inherit below; however, when I click on inherit or define, the dropbox remains blank (I have no choices - just a gray drop box)
Am I doing something wrong? Yes, my new ROM image is saved using a '.hex'.
Any help here would be much appreciated... Thanks guys...
