I have used CTEK before to keep my battery charged and had no such issues.
The only incident I heard of an ECU being shorted was this guy running tons of lights around his car and the wires burnt due to load and shorted to the car body.
One sign of this is when the mechanic used a socket wrench to loosen the negative terminal of the battery, a short is created when the wrench touched the car body.
Also found the ECU was shorted too.
