to make a 7727 run 4 low-ohm injectors in peak/hold mode, you would basically copy the 8708 injector driver setup. 2 drivers, 2 sense resistors..... to make them run in an alternate fashion, you would need the FMD2 chip present as well.
to make all 4 fire at the same time.... FMD2 wouldn't be needed, would have to tie in the 2nd driver's gate pin to the 1st driver gate pin, though this MIGHT defeat normal peak/hold operation. i'm not 100% on how GM setup the current-limiting when in hold mode.
