Can send new calibration, but old workmap is restored after power cycle

I've discovered that I can start my car just fine with my tuners cal if I send it to the ECU every time, but if I cycle the car the old map appears again.

 

I purchased the ECU second hand, could it be locked? Or am I just missing something obvious? I am new to AEMPro

It's possible that there was

It's possible that there was a "hidden" setting changed that's causing this. With the ECU connected via AEMPro, hit Ctrl + O which should bring up an Options list. It's in alphabetical order, and you're looking for an option called "Auto EE". Make sure that's set to ON. If it's set to OFF then the ECU will act as described, where settings changes will not be retained after the ignition is turned off.
