Hello
this is ecu file from same vitara 2.0 j20a 2002 that starts the car .In first post you can see that last bytes are key
03 0E 52 4A, EVERYTHING ELSE IS DIFFERENT.AND DATA IS STORED IN FIRST ROW ADDRESS 0000 NOT IN 0003 LIKE IN FIRST POST.Because it is X24C01 not 24c01.
03 0e 52 4a is also repeated 5 times in immo box ,also x24c01.
That is what TECH2 with suzuki card rewrites in ecu from address 0000
04 to adress 000
0B. I think that this rewriting is for any grand vitara with this ecu.
Regards
