Effortless Nissan Engine Cloning with Launch-X431 ECU Programmer
Launch X431 ECU Programmer and X431 X-PROG3 PC Adapter streamline the cloning process of Nissan Engine Computers, specifically for models like the 2014–2017 Nissan Leaf (23740–3Nxxx-Gen1_SH72531). The beauty of this procedure lies in its simplicity — no need for an X431 tablet.
Vehicle model and ECU model:
i.e. 2014–2017 Nissan Leaf
23740–3Nxxx-Gen1_SH72531
How to connect:
Open LAUNCH X431 ECU software, input
23740 to quickly find the corresponding ECU model, then double-click it to check
the direct connect of diagram.
Follow this wiring diagram to connect the
Launch tool and ECU, and connect the Launch tool to the computer via USB cable.
(If using It is XPROG3, you need to use XPROG3 PC Adapter in this process)
Here's a concise operation guide:
Step 1: Backup Original Nissan ECU EEPROM & FLASH
Data.
Open X431 ECU & TCU Programmer software or X-PROG3 PC software.
Connect ECU.
After connected, read
EEPROM and FLASH data separately, and save the data after reading.
Disconnect
the ECU connection.
Step 2: Backup New Nissan ECU EEPROM & FLASH
Data
Connect X-431 ECU & TCU Programmer/X431 X-PROG3 to a new
Nissan engine computer.
Repeat the same steps as step 1 to connect ECU, read
and save new EEPROM and Flash data in sequence.
(This step is a disciplined
operation. In order to prevent bricking, develop a good habit)
Step 3: Write EEPROM and FLASH data
Select the EEPROM and
Flash data of the original Nissan engine computer and write them into the new
one respectively.
Disconnect after data writing is completed.
Experience a seamless Nissan Engine cloning process with Launch X431 tools — a user-friendly solution for ECU Clone.
