Julie BMW Emulator
Instruction Manual
This Emulator is compatible with BMW vehicles. It supports both CAN-bus and K-line transmission.
1. BMW F-Series and E-Series* vehicles.
Engine + 8HP EGS Swap
Engine-only Swap
EGS-only Swap
Additionally, the original car (donor) must meet the following requirements:
It has to be equipped with one of the following modules: EWS4 / CAS / FEM
The ISN in the ECU content needs to have 16 bytes
The ISN in the EGS content needs to have 16 bytes (optional – if your project requires it)
Attention:
The procedure WILL NOT WORK if the recipient car is equipped with EWS4 / CAS / FEM module.
Example models:
F20
F30
F48
E70
E71
E90
BMW E-Series vehicles equipped with EWS4 | CAS | FEM Module and 16-byte ISN Codes.
The Emulator allows to start the car in the case of replacing a damaged ECU
You need to determine a 16-byte ISN code from the second hand ECU and write it into Julie 24C02 EEPROM memory. If the car is equipped with an EGS (8HP Automatic Transmission gearbox) or if you want to replace it, you need to determine a 16-byte EGS ISN code and write it into ECU memory.
Example models:
E83
E90
E91
E92
E93
Check the correct functioning of ECU after making Immo OFF using Immo Bypass software.
After using Immo Bypass software to make Immo OFF, you can use this program to check if the procedure has been successful, before installing the ECU into the car.

The Julie BMW Emulator is a specialized electronic module from CarLabImmo designed to bypass or simulate two critical systems in BMW vehicles: the immobilizer (IMMO OFF) and the electronic steering column lock (ESL/ELV).
Core Functions
IMMO OFF: Replaces the original immobilizer signal, allowing the vehicle to start even if there is a faulty immobilizer, a damaged ECU, or lost keys. It is frequently used for engine swaps or when installing a used ECU.
ESL/ELV Emulator: Simulates the signal of the electronic steering column lock. This is a common solution for “steering lock” errors that prevent the car from starting, saving users the high cost of mechanical steering column repairs.
Technical Compatibility
Vehicle Ranges: Supports a wide range of E-Series and F-Series vehicles.
Communication Protocols: It is compatible with both CAN-bus and K-line transmission protocols.
Installation: The module typically requires internal soldering of specific jumpers (e.g., J1-J6) and wiring into the ECU or ESL plug depending on the desired program.
Popular Versions & Retailers
Julie PRO (Version 124): The most recent and comprehensive version, supporting thousands of ECU numbers and multiple car brands beyond BMW.
Julie LITE: A more basic, cost-effective version for standard immobilizer signal replacement.
Purchase Options:
Official products are available directly from the CarLabImmo Shop Jabedul Dewan Trading llc UAE, Dubai.
