Paul,
I don't have an IAT adjuster (yet) but I can explain some theory that
might help. During WOT stabs or rapid changes in TPS or MAP the
computer goes into open-loop where the IAT is a primary variable in
fueling and timing strategy. Cooler settings result in more fuel and
timing which can be felt in the seat-o-pant meter. More fuel under
these load conditions can also cool the combustion chamber which wards
off detonation or pinging. After this relatively short period is over -
the computer goes back to closed loop, recognizes the overly rich
condition and adjusts accordingly.
I hope to be trying one (IAT adj) myself soon.
Latr,
Shane
