How to find Pre-Code in ECU file

[Nick777]

Hello to all,

I am interested to know where the pro-code is located in the ECU file. Can someone tell me?

Thanks in advance,

Not all Ecu are the same, just like the dumps,transponder and keyways. If you study the dumps by deleting and adding keys to dump and reading every time something works and comparing it. You will start to see where the changes are being apply. Look at my posting on Toyota Sequoia keys in dump that might help you understand.
