Typically DSMs use a MSD DIS 2, because we only have two channels. You absolutely can run a DIS 4 but of course you are only using 2 of the 4 channels provided because of the DIS 4 being able to be used for V8s.

My question is could the DIS 4 be a two for one? If channel 2 dies can you use channel 3 in it's place? Essentially you get two MSD units for the price of one purchased unit?
