Raw Hex Files

So besides reading a stock file directly from the ECU in the truck, where would you find raw hex file; or where can I find commercial or an open source supplier of the raw hex files?

What is wrong with reading the stock file directly from an ECU? What are you trying to do?

With EZ Lynk I'm not aware of any kind of read function/operation to allow me to read the stock calibration/file directly from the ECU therefore I'd need to outsource my stock ECU profile from an open source supplier or commercial distributor for the stock ECU file.

Sounds like EZ Lynk isn't the right tool for the job then.
