My ECU is able to drive two sets of injectors via primary and secondary banks, two fuel pumps + lifter - it is set up to run primary bank+one pump on cruise and light throttle/loads, with the second bank and pump trigged when boost/load increases; can idle fine despite using MASSIVE cams, and gives me great fuel economy and drivability to boot (as long as I'm not WOT'ing it everywhere ).
Data logging, switchable maps, shift light, two-step, warning lights, boost cut, soft and harsh rev cuts, etc etc.
I'd take it any day over a PFC or stock ecu...
