Will OBDSTAR DC706 Clone BMW MG1CS201 ECU?

Problem:

An OBDSTAR DC706 user was trying to clone a DME for a 2022 BMW X3. It’s an MG1CS201 locked ECU. He was able to unlock ECU with C4-06 adapter in boot mode, then read EEPROM, Flash data and ISN. He was able to write the EEPROM file to the donor unit. The problem is when he tried to write the Flash, it fails to erase sector 4 then quits. Is it possible to clone this module?

 

Here is the clue.

Not possible to clone/cannot directly clone. 

There is OTP sector that you cannot write to.

This is the kind of job you reprogram ECU to car, not clone.

Only sync new DME.

The ISN needs to be transferred by obd2 (need both eeproms from original and donor). Then program afterwards with Esys. Need Windows laptop and Enet cable. Then adapt sync new DME via OBD2.

OBDSTAR ECU Master Read Audi Simos 18.1 ECU

This article provides a detailed guide on using the OBDSTAR ECU Master tool with C4-01 adapter to read the Audi SIMOS 18.1 ECM (Engine Control Module) in boot mode.

 

The demonstration focuses on reading an Audi container ECM, specifically the SIMOS 18.1 variant, which is commonly found in:

• Audi vehicles
• Skoda vehicles
• Various other European cars

Laptop-Based Operation

• The tool operates entirely through a laptop, offering several advantages:
• Convenient data saving and transfer
• Easy file sharing for remote collaboration
• Simplified workflow compared to desktop-based systems

 

Connection Quality

The connections are described as:

• Clean and well-organized
• Color-coded for easy identification
• Simple to implement whether using pin-out or soldering methods

 

The C4 Adapter Connection

The C4 adapter plays a crucial role in this process. Unlike previous guides where direct connections were used, this demonstration utilizes the EPROM-based system approach. The connection setup involves:

• First Connection: Pin-to-pin connection (direct bench wiring)
• Second Connection: PCB (Printed Circuit Board) pin-out connection that requires soldering

Both connections work together with the C4-01 adapter to enable proper communication with the ECU

Reading Process

The reading process involves the following steps:

• Tool Setup: Searching for “SMOS 18” or “SMOS 18.1” in the software
• Identification: The system recognizes the Audi ECU with the TC1791 chip
• Boot Mode: The tool operates through boot mode, which is essential for accessing the ECU
• Reading Process: The tool begins reading the flash data from the ECU

Performance and Speed

One of the standout features demonstrated is the impressive reading speed. The tool reads the ECU data quickly, making it practical for professional use without requiring excessively long wait times.

OBDSTAR ECU Master Frequently Asked Questions

In this article, we'll cover the most frequently asked questions about this powerful ecu programming tool- OBDSTAR ECU Master.

The tool is divided into four packages: A, B, C, and D. These cover passenger vehicles, motorcycles, heavy-duty systems, and airbag systems respectively. Users can purchase the hardware with full package activation or choose individual package unlocks based on their specific needs.

 

Supported Vehicle Models

The ECU Master supports a broad range of manufacturers and modules. In the software, users can view a comprehensive list of compatible vehicles and systems. One notable feature is the color coding:

Red text indicates modules that are in beta version or have been recently added in the latest update. 

Heavy-Duty Vehicle Support

A major differentiator for the ECU Master is its heavy-duty line support – a feature not available in other OBDSTAR tools like the DC706. The tool supports:

    BCM, ECM, and TCM systems for trucks

    Power/torque modification options

    Solenoid writing

    Actuator hours modification

    Engine number changes

 

 Power Supply Requirements

For heavy-duty vehicle programming, the tool requires an external power supply capable of delivering:

    21–24V

    At least 5A

This is critical to maintain stable voltage during programming – especially for truck modules.

Advanced Functions

While the ECU Master currently does not have a dedicated "Advanced Functions" menu like the G3, many advanced operations are already available within the specific module menus.

 Common Questions and Answers
1. Will the DC706 Stop Working After the ECU Master Release?

No. The DC706 will continue to function normally. The ECU Master is a new tool with added capabilities (especially heavy-duty support), but it does not replace or disable existing tools. In fact, many of the functions available on the ECU Master are the same as those on the DC706.

2. Are MP001, P003, or P004 Adapters Needed?

No. Because the ECU Master is a new release, these adapters have already been integrated into the hardware. Users do not need to purchase separate adapters – all necessary connections are built in.

3. What About Fiat Systems?

Fiat has many systems currently under development. While some functions may not work 100% yet, the engineering team is actively working on implementation. Users may notice that some Fiat modules do not show a dedicated "Erase Crash" option. However, in many cases, performing a DTC erase will also clear crash data – especially on newer Fiat modules.

4. Why Do Some Modules Show Different Colored Connectors?

This is not unique to OBDSTAR tools – it's an industry-wide reality. The same module can come in multiple versions with different connector colors (e.g., white, gray, green, pink, yellow). If the tool doesn't show your specific connector version, you have two options:

    Search for the pinout online using the module number

    Contact OBDSTAR support for assistance

5. What If the Tool Won't Communicate with a Module?

If communication fails even after following the correct connection procedure:

    Collect the log data from the tool

    Send the logs along with the tool's serial number to the support team

    Ensure your tool is within the update period so that test or repair files can be downloaded

The factory will analyze the logs and may send a test file. Turnaround time can vary (24–48 hours) depending on time zones and the complexity of the issue.

6. What Are Beta Versions?

Beta versions are test modules that are still under development. If a module is marked as beta and you encounter issues, simply send the log data to support. The engineering team will gradually improve and add functionality over time.

 

Bench vs. Boot Connections Explained

One common source of confusion is the difference between bench (BENCH) and boot (BOOT) connections:

Connection Type	Description
Bench (BENCH)	Uses a dedicated connector or pinout. No soldering required. The tool provides step-by-step pinout diagrams.
Boot (BOOT)	Requires soldering to specific points on the PCB to unlock communication. The tool provides detailed diagrams showing which pins or capacitors need to be bridged or removed.

 

Log Collection and Factory Support

When encountering issues, users are encouraged to:

1. Perform the connection as per the tool's instructions

2. If communication fails, collect log data from the tool

3. Send logs + serial number to OBDSTAR support

4. The factory will analyze and potentially send a test file

5. Wait for feedback (typically 24–48 hours)

This feedback loop is critical for the tool's ongoing development, especially for beta modules.
