Hi!

I can read and write EBU WA12212930WWW using FastECU and PCM Flash, but I can't open it for editing. I tried to get definitions using FastECU, but I can't do that either. I also tried to use the file "Hitachi_EJ204_DBW.xml [12.83 KiB]" as a base and file _4244304006.xml as a definition. It also failed to get definitions.
Please help me with the definition file for my EBU

Details:
Forester SF 2000 2.5 atmo MT. EJ251/253 It does not have a MAF sensor. there is only a MAP sensor
Control unit, UJ Hitachi ECU 22611 / AG024 / A18-000 / D5Q / 0519
PROCESSOR WA12212930WWW
ECU identification number 1922040605

I attached a file with the read firmware of my EBU using FastECU- 1922040605.zip
Attachment:

Hi. Unfortunately, these definitions may be helpful for 32bit ECUs where the file size is 512kb. The maps can be found in your file. Unfortunately, I have no idea how to calculate the control sums so as not to damage your ECU.

WA12212920WWW and WA12212930WWW don't have any checksums. Just change maps and write back.

Hi, did you manage to edit this rom ? I'm working on the same ECU at the moment.
