What is also interesting, with this malfunction in S76 equipped with DECU, what behavior might you expect from the engines? The pilot response as per the ECL should be the same whether you have DECU or not, because this would be primarily indicated as a MGB failure (with secondary indications)...just don't get suckered into shutting down the #1 engine otherwise you'll give yourself a TR drive failure as well. As @megan correctly points out.
