I think we're talking about a few different things here. The TPS on the ITBS only measure throttle position, they are not an actuator to open and close the throttle.
Options for cold idle control:
1. Drive by wire setup, ECU controls throttle bodies via actuator to be cracked up during cold start - Most of us don't have this option with our ITB setups
2. Backdate' hand throttle - manually holding the ITB's open with additional linkage (in addition to the foot throttle linkage)
3. Idle control valve controlled by AEM/Megasquirt. This is basically creating a controlled vacuum leak to raise the idle without changing the throttle position or opening the throttle bodies.
4. Hold throttle open with foot pedal for 20-30 seconds until engine warms up and holds idle.
I'm in Houston and option 4 works well for me, cold starts aren't really an issue so i've never needed additional measures.
