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.
Write flash successfully. Honda’s low idle problem was solved.
OBDSTAR DC706 Read/ Write 2014 Dodge Ram EDC17C79 ECU
Although the OBDStar dc706 doesn’t show the Dodge Ram being supported it does work to read and write internal flash and eeprom.
The ram Pinout shows the can wires in a different place and only reads with Hp Tuners in the pinout it’s original hooked up in. However if you switch the can wires and add the gpt wires you’re able to use the OBDStar dc706 to read/ write these ecm’s and effectively clone them along with altering vin numbers.
You can see this pinout. Here got the CAN Wires positive, negative.
We all know the OBDSTAR supposedly will only read and write the
Jeep.
There is no pinout for Dodge like we have on the HPTuner.
We’re just going to leave this pinout. Then hook up our OBDSTAR DC706 ecu programmer.
We have this hooked up same ECM. We switched our CAN wires to a different pin.
We’re using this exact pinout right there.
We’ve switched an alltime
positive to an ignition there.
You can read the internal Flash and you can write both of those.
If you
want to start cloning the ECMs, you can do it underneath the Jeep.
You can also find the VIN number.
