Hot restart flag is used for what it describes with its name. $0D has fuel modifiers based on temp etc. Here is a section from the disassembly for $0D.
;---------------------------------------------
; CRANK FUEL MULT Vs. Vs. RPM IF HOT RESTART
;
;
; TBL = MULT * 256
;---------------------------------------------
ORG $4DAC ; MULT RPM
;----------------------------------
L4DAC FCB 255 ; 0.996 0
L4DAD FCB 255 ; 0.996 100
L4DAE FCB 166 ; 0.648 200
L4DAF FCB 166 ; 0.648 300
L4DB0 FCB 128 ; 0.500 400
L4DB1 FCB 128 ; 0.500 500
L4DB2 FCB 128 ; 0.500 600
L4DB3 FCB 128 ; 0.500 700
L4DB4 FCB 128 ; 0.500 800

You can search the disassemblies here for lots of Parameters in $0D.
