Impreza voltage high

trying to upload a map to an impreza, the test write works fine but the actual write keeps returning this

has anyone worked out how to get this sorted without leaving the lights on etc?

I am able to write using ecuEdit, just not EcuFlash and i need it to be EcuFlash to upload a patch for launch control.

I have tried leaving the lights on and working the windows when attempting to write now and no luck

12.62V is only just beyond the allowable range IIRC... put a small diode (1n4148 or 1n914 etc) inline with the 12V wire (anode to cable, cathode to car). That will drop it by about the right amount.
Not the most elegant solution, but it should work.
Ideally you'd also decouple the ECU side of the diode to ground (OBDII connector ground) with a capacitor; 10uF 25V should be plenty. This should make the 'new' 12V a little more robust.
