LNRalph - you would need to establish the max continuous. max contingency and any time-limited figures (ie 5min take-off) for the various parameters and use these as your benchmarks. The FLI is what it suggests, a first limit, whether that be Tq, Ng, T4 or bananas and that first limit will be either max continuous or max contingency depending on the manufacturers limits. You just have to juggle the numbers so your software recognises which iit is hitting first. I expect the yellow band will be max continuous and the red line will be max contingency.
