Hello everyone I have a 2013 LML and I am ready to modify her. I have been reading and researching and have decided to go with efi live. I am however confused on how it works could I get simple explanation on what I need to purchase as far as equipment. Looks like there are 2 devices.

Welcome, EFI Live is custom tuning. You flash 5 or 2 (Dsp5 vs dsp2) tunes onto your ECM/TCM, and use the DSP5/2 switch to switch the tunes that are preloaded. You may want to look into other mods for now

congrats you will like EFI tunes from any rep tuner. But unless you do not have a warranty left I would stay away from the ECM, or get another and tune it and keep the factory with the factory tune. GM is trying to deny all and every body whose tunes are modded, some dealers might look the other way but when push comes to shove GM pays the bill and they might want to know if the ecm has other then factory tunes, and from my understanding the LML ECM holds the last tune written
