Disconnecting the battery with the key on will not hurt the ECU.
The ECU is only damaged from the battery being connected backwards, or from improper testing (such as the use of a "Test light") on the inputs and outputs of the ECU.

Hey hombre. Ningún dar vuelta al coche apagado con la llave encendido no lastima el ECU. Las únicas maneras que usted puede lastimar el ECU están conectando la batería al revés, que puede también soplar encima de la batería. Eso también freirá todos los argumentos. Dudo que con una luz de la prueba lastimará cualquier cosa, pero su posible.

Most of the ECU's sensors and actuators are 5 volt... what do you thing will happen when using a test light hooked up to a 12 volt source or completing a 5 volt circuit?
I have seen ECU's burned up because someone used a test light on the BAC Valve. I have seen ECU's wasted because someone hooked a test light up and probed the ACV with the key on.
