Compare OBDSTAR DC706 Bench V2 and V3 Cables
What is the difference between OBDSTAR DC706 bench V2 and Bench V3 jumper cables?
1. The jumper cable that comes with DC706 package is the
Bench-B V2 cable.
It is used with P004
adapter to clone some ECMs/TCMs.
The bench-B V2 cable connects with P004 adapter like this:
2.The jumper cable that was purchased separately or comes with MP001 is the Bench-A V3 cable. It is used for P003, P003+ and MP001 adapters.
It is used to clone some ECUs.
The bench-A V3 cable connects with MP001 programmer like this:
Copy GM BCM 13589056 Using OBDSTAR DC706 Tool
This guide demonstrates how to clone a Vauxhall/Opel GM BCM (Body Control Module) with part number 13589056 using OBDSTAR DC706, including immobilizer data transfer and PIN code extraction. This process is essential when replacing a faulty BCM while retaining original vehicle security data.
Tools Required
- OBDStar DC706 (or X300 Classic G3)
- P004 adapter
- 12V power supply (for bench testing)
- Replacement BCM (same part number)
Step 1: Prepare the BCMs
Identify Modules:
- Locate the original (donor) BCM and the new replacement BCM (ensure part numbers match).
- Verify both are Continental-branded modules (common for GM/Opel).
Pinout Setup:
Select GM BCM Continental 70F3469 +95160 option.
- Refer to the wiring diagram for correct connections:
- Pin 1: Ground (GND)
- Pins 4 & 5: 12V Power
- Pins 23 & 24: CAN Low/ CAN High
Step 2: Read Data from the Original BCM
Power Up:
- Connect the original BCM to the OBDStar DC706 tool using the wiring harness.
- Apply 12V power to Pins 4/5 and ground to Pin 1.
Extract Data:
- Open the OBDStar software, navigate to GM > Body Control.
- Select "Read EEPROM" and save eeprom data.
- Select "Read Flash" to back up the flash data.
- Retrieve the PIN code (e.g., 0427 in this case) and note it down.
Step 3: Write Data to the New BCM
Switch Modules:
- Disconnect the original BCM and connect the new BCM using the same wiring.
Transfer Data:
- In OBDStar, select "Write EEPROM" and load the saved backup file.
- Select "Write Flash" to transfer the firmware.
- Note: Skip backup for brand-new modules (no existing data to preserve).
Verify PIN Code:
- Read the PIN code from the new BCM to confirm it matches the original
Step 4: Final Checks
- Disconnect all wiring and power.
- Test the cloned BCM in the vehicle:
- Ensure the immobilizer recognizes the keys.
- Check for fault codes (clear if necessary).
Done.
Chrysler GPEC2A ECU Unlock Now on OBDSTAR DC706
The OBDStar DC706 ecu tuning tool recently added a new feature that has sparked excitement among automotive enthusiasts and tuners: an ECU Unlock tab for the Chrysler GPEC2A ECM. This update suggests a streamlined way to unlock ECUs for tuning, potentially eliminating the need for manual hex editing or file transfers. But does it actually work with popular tuning software like HP Tuners? Let’s dive into the findings.
The Promise of a One-Click Unlock
Traditionally, unlocking a GPEC2A ECU for tuning involved cumbersome steps:
- Transferring files to a USB
- Manually editing hex files
- Scrolling through lines of code to make adjustments
The new "Unlock ECU" tab in the OBDStar DC706 software hints at a simplified process. The hope was that this feature would allow users to bypass manual modifications, making it easier to prepare the ECU for tuning with third-party software like HP Tuners.
Testing the Unlock Feature with HP Tuners
To verify its effectiveness, a user conducted a series of tests:
1.Initial Attempt:
- The "Unlock ECU" function was executed, and the process completed successfully.
- However, when attempting to write a tune via HP Tuners, the ECU remained locked, displaying an "Incompatible PCM Software" error.
2.Second Attempt (Boot Mode):
- After consulting the guide (which initially went unread), the user tried unlocking in boot mode using a P004 adapter and a 120-ohm resistor.
- Despite following the correct procedure, the unlock still did not allow HP Tuners to write to the ECU.
Manual Unlock Success:
- As a last resort, the user manually unlocked the ECU using traditional methods (hex editing).
- This time, HP Tuners accepted the file, confirming that the manual process still works while the OBDStar’s unlock feature fell short.
Why Didn’t the OBDStar Unlock Work?
The exact reason remains unclear, but possible explanations include:
- The unlock may only work with OBDStar’s proprietary tuning tools, not third-party software like HP Tuners.
- The feature might still be in beta, requiring further refinement.
- There could be additional steps not covered in the initial testing.
Conclusion: A Step Forward, But Not a Complete Solution
While the OBDStar DC706’s "Unlock ECU" feature is a welcome addition, it currently does not appear to work seamlessly with HP Tuners. For now, tuners may still need to rely on traditional manual unlocking methods.
However, this update suggests that OBDStar is moving toward simplifying ECU tuning, and future software revisions could improve compatibility. For those eager to test it, staying updated on official releases and user feedback will be key.

OBDSTAR DC706 Idle Speed Repair for 2016 Honda Civic 1.5T
A 2016 Honda Civic with a 1.5T engine exhibits idle shaking when in D gear. The dashboard shows that the engine speed is about 600–650 rpm. Using a diagnostic tool shows no fault codes for the vehicle, and hardware inspection also reveals no abnormalities. Cleaning the throttle still doesn’t solve the problem.
10th generation Civic low idle problem can be perfectly solved by OBDSTAR DC706 using its one-click idle speed repair function.
Tools required:
OBDSTAR MP001 programmer or P003+
Power supply
ECU
Procedure:
Quick search Honda KEIHIN PGM-FI TC1782 ECU. Here choose MP001 bench mode.
Check instructions and wiring diagram.
Connect ECU with MP001 follow the wiring diagram. Don’t forget to connect with an extra power supply.
Connect ECU.
Read and save INT flash.
Write INT flash. Select flash data just read.
Press Yes to verify data (correct checksum).
OBDSTAR DC706 detects the engine idle speed 620, adjust the idle speed to around 800 RPM will solve this issue.
Confirm and write int flash.
