Narrative:

The captain of this flight, before starting out on our flight to reading, PA, briefed me that he was using the MEL'ed eec's on this aircraft. He explained he knew what the problem was with the eec's and they should not cause us any in-flight malfunction but if they did he would turn them off. Being new on the aircraft plus flying with a management pilot who taught my emb-120 ground school I figured he knew the system better that I did. I agreed with his logic so we flew 2 legs using the eec's in the on position even though I knew we should have followed aircraft MEL's . The eec's seemed to work throughout the duration of the flts.
