Robust support for Motorola/NXP (HC05, HC08, HC11, HC12, 9S12, 9S12X), Texas Instruments (TMS370), and STMicroelectronics (ST10) families.
Before modifying a single byte of data, perform a full read of the target memory (EEPROM/Flash). Save this raw hex file as an untouched master backup (e.g., original_dump_backup.bin ). If the modification fails or the vehicle fails to start, you can easily re-flash the original configuration to restore functionality. Address Voltage Configuration Quirks
Download the corresponding device license file ( uuprog.lic ) matching your serial number. 2. Aftermarket / Clone Hardware Packages

The is a professional-grade automotive ECU and MCU programmer developed by Elrasoft . While you are specifically looking for version 2.2 , please note that the official Elrasoft site lists the latest software release as V3.5.0.0 (as of February 2026). How to Download UPA-USB Software
Click the Read button. The software will perform a connection check and then display the chip's data in the hexadecimal grid.
Removing chips from a circuit board poses a risk of damaging delicate surface-mount device (SMD) pads. The V2.2 software optimizes ISP/ICC protocols, allowing you to solder a few lead wires directly to the board points to read and write data safely without desoldering the MCU. 3. Integrated Scripting Engine Robust support for Motorola/NXP (HC05, HC08, HC11, HC12,
Download the software archive (typically a .zip or .rar file) and extract it to a dedicated directory on your local drive, such as C:\UPA-USB-V2.2\ . Step 2: Run the Setup Installer
