The defaults are in hwtable.c [1].

To modify the compiled settings, you have to modify it and recompile.
To modify the runtime settings (based on the defaults), you can modify
/etc/multipath.conf (see its manpage [2] with 'man multipath.conf').
You can verify the the setting values used during multipath discovery
with 'multipath -v3' for example, or "multipathd -k'show config'".
Hope this might still help at this time,
