Do you know the ROM file typically in the naming convention has the ECU Part number it meant to be used on.
Example:
1A32C base tune ( this I what I got from UpRev)

Now the ROM File you got ( Second Hand ) May have similar naming convention.
That being Said it MUST Match Your ECU's Part Number. You cannot take a ROM file from Car A and use in Car B.
ECU Part numbers vary year to year model to model.

Most likely Jared @ UpRev may ask that you send it in and they can fix it.
