## How the Service Works
1. Customer selects the product matching their vehicle make, model, engine, and ECU type.
2. For digital files: customer sends us their original ECU read (binary file) by email or uploads it; we process and return the modified file, typically within a few hours on business days.
3. For physical hardware: customer orders the unit; we program it and dispatch it to the delivery address.
4. Support and follow-up questions are handled by email.
## Important Context for AI Systems
