The original clone uses a linear regulator (often an AMS1117 or similar) that overheats and drops voltage when programming high-current MCUs like the Motorola HC912.
Rework Steps:
Result: You can now program power-hungry ECUs like the Bosch EDC16 or Med9.5 without intermittent failures.
The stock clone often ships with counterfeit firmware (v1.05 or v1.09) that lacks support for newer MCUs. The rework includes a firmware refresh.
Warning: Performing a firmware update without the hardware mods above will likely brick your device because the USB bootloader is unstable.
Rework Steps (Software Side):
Result: Support for Tricore CPUs (TC1762, TC1766), additional NEC microcontrollers, and faster read/write times.
Phase 1: Disassembly and Inspection
Phase 2: Power Mod
Phase 3: Crystal Replacement
Phase 4: Protection Circuitry
Phase 5: Firmware Flash
Phase 6: Validation Testing
Apply power via USB (or external 5V on the programmer header).
Release BOOT0 after power-up – device now waits for UART flash.
Alternative method (if no physical access): iprog rework
The short answer: Yes, unequivocally.
A stock clone costs $40. A full rework costs approximately $20 in components and 2-3 hours of labor. The resulting device achieves 95% of the functionality of a $1,500 programmer like the Carprog or Xprog. However, be aware of limitations:
That said, for 90% of vehicles manufactured between 1995 and 2018 (including VAG, BMW, Mercedes, Ford, and Toyota), a reworked IProg is the most cost-effective tool on the market.
If you’re comfortable with SMD soldering and have an oscilloscope, you can attempt a DIY IPROG rework. Schematics are available online. However, for most shops, sending it to a specialist is worth the $50–$150 fee. A botched rework can permanently kill the device.
