Hi all I'm looking for advice on best path to proceed with my issue. Bought a car that has aftermarket ecu that to change anything with the calibration has been password protected.

Have tried to flip the lock offsets and crc locations but that enabled a backup defence in the exe where I view the locked file as it suspected I was trying to load it to another ecu.

I've tried patching the exe that opens and views the file to not require password protection but made no difference still same result.

I have currently built a python script to fully automate each step of the password input process such as opening menus , auto click, auto fill and I am using a rockyou.txt data file for it to source from. My issue is this is extremely time consuming at approx 3 seconds per attempt this could take years.

How would you improve on current method or approach differently to the issue ?

Thanks in advance I'm only about 5 weeks into anything like this so please excuse any ignorance
