The only other brainstorm I had was to use an 'iff' for the PE Enabler Tables (via look-up).
I.E., iff RPM & TPS% this..then..

Every other solution is a lot of work. Remember, we just want to know if LTFT's are active.
You can always default LTFT's to 1.00 and use WO2BENS for the entire practice.

We may be stuck with a 'stupid', but easy solution as is..

Question is, how does the PCM determine when it is in PE Mode?
