TCU wiring Question

Can Any of you with some electronic knowledge tall me if I can "Fool" the TCU on my 95 Impreza 1.8 4-EAT coupe into thinking it's warmed up sooner so the torque converter will lock up sooner, as it won't lock up until I am almost to work, and would like to squeeze every MPG out of it that I can.

I plan to eventually swap it to a 5-Speed, but until then, would like to make the 4EAT do a little better for my commute...
