It's a multiplier.
It "basically" takes the desired PW for a given ICP/MFD (in the pulse width map) and multiplies it by the value in the multiplier.
So by all rights, you can either jack up the values in the straight pulse width map to reflect what you want the PW to be for a given MFD/ICP that is not based on EOT so you can really churn out the powah upon first startup on a -10F day........
OR
You can calculate (within fairly close reason) what the actual PW will be if you do some math. The PW multiplier map allows injection pulse width changes based on EOT instead of just allowing a ton of fuel while the engine is cold.
