I have a question regarding DSP2 & DSP5 switches. I have a LBZ Duramax that I have loaded a tow tune into with EFI Live. I would like to switch back and forth between an economy tune I have (when DD'ing and the tow tune when, of course towing.) So I really only need a DSP2? It is my understanding that when I upgrade my OS to a DSP OS, I do so with the stock tune file, and load the alternate tune which modifies the first one (stock that was the full reflash) So in essesnce I would need a 3 position (theory) switch capable of swtiching between stock (base that economy and tow tunes use to modify,) economy, tow. There are several different scenarios here that I could ask, but you get the idea of what I'm asking here. I understand how to upgrade the OS, but basically how do you select which tune is assigned to which # setting.
Thanks,
Andrew
