1.  Product Description

View the Product -The UPA USB Programmer Diagnostic Tool (Version V1.3) is a professional-grade ECU and EEPROM programming interface designed for automotive tuning, chip repair, and diagnostic tasks. This versatile USB-connected device allows you to read from, write to, and modify non-volatile memory in microcontrollers and automotive control units using a wide range of adapters.

At its core is the UPA-USB hardware (Hardware Version V2014), paired with updated V1.3 firmware and software, delivering broad support for legacy and modern automotive chips. The programmer features a 40-pin ZIF socket (for DIP / DIL devices) and a 16-pin SOIC ZIF socket, simplifying access to a diversity of packages. It also includes a 10-pin ISP connector for easy in-circuit programming via flat ribbon cables or ISP adapters.

One of the major advantages of this tool is NEC support — even though the NEC adapter might not always be included in all packages, the firmware is ready to work with NEC-based devices. The tool also supports serial flashes, a variety of EEPROM types, and microcontroller families like Motorola MC9S12 and PIC, making it a comprehensive tool for ECU tuning, system cloning, and embedded control unit modification.

To ensure safe and stable power delivery, the UPA USB provides regulated output voltages. The programmable jumper next to the ISP connector enables or disables target power supply from the programmer. This ensures that you can safely power sensitive target devices or let them use their own power source.

6. Usage Considerations / Best Practices

• Use quality USB cable and ensure stable PC connection when programming.

• Confirm the correct target voltage (1.2V–5V) before enabling power to the chip.

• Use the appropriate adapter for the chip you are working with; wrong adapter can damage the device.

• Back up chip data before performing write operations or tuning tasks.

• After writing, verify data integrity by reading back and comparing.

• For in-circuit programming, ensure stable connections to the ISP header.

• Use the script functions if you need to automate complex read/write tasks or bulk operations.
