Hi everyone,

I’m looking to build a full collection of original US ECM files (stock dumps) for Mercury outboard engines from 2000 to the present.
I’m especially interested in:

• EFI
  
• Optimax
  
• Verado
  
• FourStroke
  
• Racing models
  

My goal is to compare US vs EU calibrations and possibly use them in conversions, diagnostics, or reprogramming purposes.

If you have:

• Any original (unmodified) US ECM dumps
  
• A file library (paid or free), or can point me in the right direction…
  

I’d really appreciate your help 🙏
Willing to pay or trade files. I’m based in France.

Thanks a lot!

What makes you think that they are different?

Which models have different part numbers referencing a US and a European ECU?
