There are at least two generations (formarly three including Arabic EJ202).
Could you upload your ROM/ecuID/CaseID ?

The first one based on UnisiaJecs WA12212920WWW chip may permanently fail during reflash.
More recent ecu based on WA12212970WWW chip may be reflashed in a safe manner.

The last generation involves 4 4byte checksums + 2 1 byte checksums.

Sasha,
I have a 2007 ADM Liberty NA with air pump codes I want to turn off, It has the WA12212970WWW chip in it, Is it possible for me to reflash this ECU and if so how would I go about doing it? I noticed you said it could be read out with SSM, will this flash a modified file back? and do checksums nned to be corrected before hand?
can this be used as SSM to read and flash

Thanks for any help.

I have never seen MY06/MY07 ADM NA Hitachi.
This is the way to read the ROM.

Have you already disabled Secondary Air system and recalculated checksums?
I am afraid that currently you could not reflash Hitachi ROM yourself.

No, i have not started yet, thought i would make sure i can complete the job before i begin. Is there any way to flash back the mod file with any tool?

I do not know any applicable tool available .
I do flash them on the bench.
