Hello,

I have a Nissan Altima 2.5L with a Hitachi BED509-300 ECU, hardware 237036CA3A and software 237106CE5E. I use PCMFlash Module 59 and Scanmatik 2.

Is there a way to lock or protect my tune inside the ECU to prevent others from reading, copying, or reusing it, while allowing me to update it later?
