After downloading the software, you will see several packages:
the first one is the application;
the second compressed package contains the wiring diagram;
The third one is the driver.

Unzip the wiring diagram first and then unzip the driver.

First open the STM32 driver.
Take the computer system xp win7 or WIN8 / WIN10for example 
If it is a 64-bit system, choose 64, If it is a 32-bit system, choose X86.
Just install it, and then double-click “ Install”. 

Then open the application.
Choose the option “options”and then select“port”.
PS: If the driver is successfully installed, the device COM port will display.

Click on “open”, in this way, the device can be successfully connected.

Then we look for the wiring diagram.
Pay attention: the number on Denso engine outlook is not necessarily correct.
The correct way: After opening the board, refer to the number on the computer.

Look at this ECU, the number is 2750363410.
Open the wiring diagram.
Select the corresponding ECU number, the chip CPU number 76F0070 is also shown on the wiring diagram.
Or refer to the number on the chip to select. 

Step 1.
Use the two cables of Toyota ECU Flasher to connect to the socket of the engine. Connect a ground wire and live wire to power the engine ecu. 

Step 2.
Find our jtag interface and solder it with the soldering plate. 

Step 3.
This type of engine requires a bot point from the back shown as follows.

Plug the BOT point into one of the BOT pins on Toyota ECU Flasher .

Connect Toyota ECU Flasher.

Plug the wire.

Tips:
The Boot pin is always facing the inside of the engine and the other side keep facing the outside.

Once connected, open the application.
Select the corresponding CPU model from this option.For example,76F0070 series. 

Operate as follows: 
First click on “read” to read data until 100% ok with hardware ID, the Checksum is also OK, in this way we don't have to read it. Two data for comparison to ensure the integrity of the read data.

Step 4.
Finally we click “Save” to save successfully.

Step 5.
Write date. Click on “Open” button, select the corresponding data, click on “Write”.

In conclusion: 
For the Toyota Denso engine ECU, when doing some data modification, it may fail to write because the number is wrong, then Toyota ECU Flasher is able to perfectly fix this problem, as long as the CPU model is the same, it can be written.
