Or use a control variable (p).
Code:
... | awk -v vIn="$wIn" -v vOut="$wOut" '($0 ~ vOut) {p=0} p {$1=$1; print} ($0 ~ vIn) {p=1}'

The order of the three statements determine if the boundaries are included. Here both are excluded.
This is Regular Expression: special charcters need to be escaped in $wIn and $wOut.
The following variant works with plain strings:
Code:
... | awk -v vIn="$wIn" -v vOut="$wOut" 'index($0,vOut) {p=0} p  {$1=$1; print} index($0,vIn) {p=1}'
