Well I'm confused now.  I am seeing 400mS to erase one sector and prog 
1K of flash.  Are you waiting to see if the prog is actually done?  I 
am doing that, and the IAP_BUSY status does not go down until 400mS.

I can also verify that if the power goes down in 300mS the programming 
does not get completed.  The erase does, but not the prog.

So my 1024 bytes to prog is certainly taking much longer than 500uS as 
you suggest.

Any ideas?

Thanks,  Chris.
