AUX input - IAT or WideBand o2?

[FI_Rubicon]

Is it a supported configuration to just solder the COMP jumper pads while leaving the F and the W pads unsoldered? Only curious here.

How is flow compensated when the voltage goes up without spiking, indicating a lean condition - does it compensate by adding more spray?

I still wonder if using IAT as the AUX and compensating on that would be more useful to a jeep that will be crawling along a lot and susceptible to heat soak. It makes sense that a spike in WBO2 is the better choice for failsafe but I am referring to just compensation here.
