HP Tuners is often used in GM vehicles and interfaces with a laptop to the stock PCM.

• A. Interfaces with a replacement PCM and laptop
• B. Often used in GM vehicles and interfaces with a laptop to the stock PCM
• C. Uses handheld between stock PCM and laptop
• D. Logs data

Answer: (B)

HP Tuners is a PC-based tuning tool that connects a laptop to the vehicle to access the factory (stock) PCM. The essence is that you use a computer to communicate with the stock engine control unit, typically in GM vehicles, to read, modify, and upload calibrations. That makes the statement the best description: it highlights both the GM applicability and the laptop-to-stock-PCM interface. Using it with a replacement PCM or as a handheld between the PCM and laptop isn’t the typical setup described by this use case, and while logging data can be part of the workflow, the primary role is the computer-based tuning interface to the stock PCM.
