Shouldn't be a problem.  I opened up the software to see the specific range
of adjustments..

you can set the gain at the following temperature threasholds (all in deg.
C.):

-13, 3, 19, 35, 51, 67, 83, 99, 115

agreed.  There are aftermarket EFI systems out there with provisions for idle
control built in,  eg:

SDS efi:  http://www.sdsefi.com/specific.html (scroll toward the bottom to
see a pic of the ISV or search for "fast idle")
