Which device connects the ignition control module microprocessor with a USB cable?

• A. Tuning software
• B. Piggyback controller
• C. Hand-held controller
• D. EMS

Answer: (C)

The device that provides the USB bridge to the ignition control module’s microprocessor is the handheld controller. This portable unit is designed to plug into the ignition module and expose a USB connection to a computer or tuning software, allowing you to flash firmware, read diagnostics, and send calibration data directly to the processor. Tuning software by itself is just the program that runs on a computer; it needs a hardware interface to actually communicate with the module. A piggyback controller sits in the signal path to modify inputs/outputs but isn’t primarily a USB bridge. An EMS is a complete engine management system, not the single interface that links the microprocessor to USB.
