Modifying ECU software is a reverse engineering problem. And a very challenging one at that.
You could start with basic reverse engineering topics and work your way up. Get a copy of your ROM, get it loaded in a disassembler, and start reverse engineering.
The number of people who do this worldwide is extremely small, and most of the good ones do it as a business. They’re not sharing their business secrets.
