Fuel flow programming with a SDSEfi system

I am setting up a SDSefi system to interface with an EIS 2000, the SDS outputs 25000 pulses per gallon,
I would like to calculate a good starting point for the FF calibration.
any ideas on the formula for fuel flow?
Thanks

Hxr fluid temp

I have an HXr and I am trying to get an ft-1827-2 to work to measure gear box temp on the discreet analog input 6. I am using the HXr internal resistor and have tried all of the Eis calibration settings. Any suggestions?
