    • An engine control module (ECM) (104) having a plurality of driver banks (120) is provided. Each of the driver banks (120) is configured to drive a plurality of combustion control elements (106). The driver banks (120) include two low side driver circuits (204(1), 204(2)) and a high side driver circuit (202(1)), the high side driver circuit (202(1)) in each of the plurality of driver banks (120) being shared pairwise by two combustion control elements (106(1), 106(2)). Each one of said at least two low side driver circuits (204(1), 204(2)) is respectively associated with the two combustion control elements (106(1), 106(2)). The ECM (104) includes a field programmable gate array (FPGA) (122) coupled to the plurality of driver banks (120) and configured to provide firing signals (600) to at least twelve high side driver circuits (202(1-202(12)) to simultaneously drive at least twelve combustion control elements (106(1)-106(12)) respectively coupled to the at least twelve high side driver circuits (202(1)-202(12)).
