Julie™ FORD MAZDA
Immo Off Emulator for Ford and Mazda. From a Ford KA to a Ford Galaxy, from a Mazda 323 to an MX5.
Julie™ FORD MAZDA is a brand-specific emulator from CarLabImmo that replaces the immobiliser signal in Ford and Mazda ECUs. It works with Siemens and Visteon ECUs in Ford, plus Denso, Lucas and Mitsubishi ECUs in Mazda. It also covers Ford cars with PATS and a 4C key transponder, and selected donor ECUs for engine swap projects.
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.
