Hello, does anybody can me to help the read/write ECu of my Subaru WRX 2003?
I need to know which software and interface is necessary to do the bootloader.
I thank the help

That doesn't look like WRX03.
Plastic case, SH7058: looks like either 06/07 DBW serial or 07-09 CAN.

I have this ECU:
- ECU WRX 07.jpg (67.44 KiB) Viewed 9003 times
But it's WRX 07 EUDM.
You have next version of same ECU. So try WRX 07 or STI 07
If you interested I can make detailed photo of main board to compare.

Hello, mad max, here they are the pictures that I have. I am not sure of the year of the car because here in the py it is difficult to know.
Do you can me to help to read this ecu in boot mode or ZTAG?
Best Regards

You can't read these in SHBoot mode; the first thing it does when you enter that mode is erase all flash.
Just use ECUFlash.

But is it possible to read/writte for the ZTAG?
This ECU is blocked because it was interrupted the flashing
Thank you very much.
Regards

Don't know about ZTAG (I presume you meant JTAG?). Reflashing is possible using SHBootMode. You need to have a stock ROM file first.

I understand, in the outline of the shbootmode I don't know which component is this of the picture.
Do you have a picture of your connected interface in ECU?
I thank your help a lot.
When I get to read this ecu I can ask for the a friend to read ECU of your car to have the ROM.
Regards

I believe all the SHBootMode pins come out to one of the rows of pads near the back edge of the board. You may have to use a multimeter to trace which pads go to which MCU pins. When I did this (only once), I soldered small wires to these pad holes.
Alternatively I think there are test points labelled as per the schematic above: P409 for instance. That's probably the easier way to go. They're easy to solder to.

Hello, I put up the interface as show the
http://www.openecu.org/index.php?title=SHBootMode but I'm having trouble so that Windows recognizes the hardware.
Where I can find the driver for installation on usb?
Also I do not see the datasheet of the micro the pins that I should connect. Which pins should I connect the interface?
I appreciate the help in advance.
Best Regards
