I need some help. I am trying to make a Calculated Pid that defines PE Mode.

Heres my PID so far..

*CLC-00-004

factor 0.5 1.0 .2 "{GM.EQIVRATIO} > 1.00 & {SAE.RPM} > 2000"

So far what it gives me is a (1) if it is 'true' and a (0) if false. Does anybody know how I can define an expression that might say 'PE Mode' and Non-PE Mode? I have been trying to utilize theEFILivesyntax, but I am stuck.'iff'

If I can pull it off I want to make 'PE Mode' a condition for yet another PID..

Anybody know? Thanks in advance..
