Welcome! You’ve landed at Busted Knuckle Garage, an automotive lifestyle brand with a story like no other. Founder Warren Tracy dreamt up this idea years ago while living deep in the Grand Canyon—an unlikely place for a car enthusiast, but that’s exactly where the vision was born. One morning, Warren woke to find a rough cartoon sketch of a garage he’d drawn in his sleep, without any memory of doing it. That sketch soon became a reality, and after twenty years of passion, dedication, and grit, every piece of Busted Knuckle Garage merchandise you see today comes straight from that dream. No corporations, no assembly lines—just one guy, a love for classic cars, and a trusty wrench.

For an automotive technician, deciphering data is crucial, but understanding which diagnostic tool works best for each unique scenario that may arise in a service bay is equally important. Vehicles today are equipped with increasingly complex computer systems that generate vast amounts of data related to engine performance, emissions, and other critical functions. This data provides essential clues about the vehicle’s condition, but knowing how to interpret it effectively requires skill and experience.

Technicians must be able to distinguish between normal and abnormal readings, identify patterns in the data, and trace the root cause of a problem. Decoding this information is foundational to accurate and efficient vehicle repairs.

However, deciphering data alone is not enough.

Different vehicles, makes, models, and even specific systems within those vehicles may require specialized diagnostic tools. What works for a particular brand’s transmission issue may not be suitable for diagnosing a complex electrical problem in another car. Selecting the right diagnostic tool ensures that the technician can access the most relevant and detailed information, reducing the chance of misdiagnosis and increasing the speed and accuracy of repairs.

TOPDON USA VP Chad Schnitz joins us for an in-depth conversation, offering valuable tips on how to succeed in the service bays by selecting the right test equipment for each specific diagnostic procedure.
