You need the flex (ZL1) pump, not the injectors. E38 FPCM stays unchanged for NA, handled by ECU. Use the GM fuel composition sensor, no need to complicate a toothpick.
I'd use a flex tune OS to start rather than flagging bits and copying bobs higgledy piggledy. Ethanol flex can be really fuel efficient, use GM tables and modifiers base tune for 2013 L99 or 2014 VF Commodore.
