Package B — Mileage Algorithm Lessons
Explore how mileage-data algorithms work through 30 basic and advanced lesson topics, video demonstrations, example files and six small .exe learning tools.
- Lesson topics
- 21 basic + 9 advanced
- Included materials
- Videos & example files
- Learning tools
- 6 small .exe tools
Strictly for demonstration purposes. Learn how the examples work; practical repair requires further knowledge and experience.
Understand the data behind the tools
You use the tools. Now explore how they work.
If you are curious about how airbag crash records are cleared and how mileage data is repaired, this package introduces simple algorithm demonstrations. Even after working on thousands of airbags and instrument clusters, there is more to learn about what happens inside the data.
Demonstration only
These are simple educational examples. Owning the package does not mean you know how to clear crash records or repair mileage data on a vehicle. There is still a long way to go.
