Its open loop, based on MAP and RPM determines the output of the 7th injector for the added fuel. The 7th doesnt introduce fuel at all in closed loop, it only kick on under boost.
It has its own internal map.
Its an AIC
All the tuning has been done at WOT

I had an AIC on my SR with the 7th, the truck pulled the fuel I put in. But this could purely be differences between years. So the AIC on your truck puts out an independent pulsewidth from the stock ECU based on boost? That makes sense. My TRD 7th I had on my SR was triggered by open loop as well, but was load based as well, not MAP.
So do you get a lean condition when under load but not WOT? Or can the injectors keep up? Also, what happens when your going up a hill load is greater than 80%, but your throttle position is 45% and your ECU goes into open loop and you have boost? These were some of the issues I had with my SR, (S-Runner).
