Julie™ JAPAN KOREA
Immo Off Emulator for Japanese and Korean vehicles. From a Daewoo Matiz to a Yamaha YZF R1.
Julie™ JAPAN KOREA is a brand-specific emulator from CarLabImmo that replaces the immobiliser signal in Japanese and Korean vehicle ECUs. One emulator works with Bosch, Continental, Delphi, Denso, Hitachi, Kefico, Kemsco, Lucas, Mitsubishi, Siemens, Sirius and Zexel ECUs in Daewoo, Honda, Hyundai, KIA, Mazda, Nissan, Suzuki and Toyota, plus the Chevrolet, Subaru and Yamaha models listed below.
How it works
Step 1
Find your ECU
Check the ECU number on the label. Pick your car brand below, or search this page for the number.
ℹ️ The ECU numbers listed are tested. Other numbers of the same ECU type may work too. To confirm, create a free ticket on our forum.
Step 2
Install Julie
Follow the manual for your ECU type. It is always up to date. Videos give a quick overview of the job.
Step 3
Immo Off with Julie
Julie gives the ECU the immobiliser signal it expects, enabling car start.
Built to last, down to the PCB

The board inside Julie™ is made for life in a car, not on a shelf.
Automotive MCU
Improved performance and stability, even in harsh weather conditions.
Gold-plated solder pads
Gold resists oxidation, so Julie™ keeps working for decades.
Externally programmable EEPROM
Program selection and values are written to the 24C02 EEPROM on board. With the 24C02 EEPROM Memory Adapter for Julie™ Emulator, you no longer need to solder jumpers or unsolder the EEPROM.
