GM Application Update, will it mess up the tune?
I helped my neighbor tune his 2018 Silverado a couple months ago and he just called and said his screen said: next ignition/application update close marketplace to update? Unfortunately he is on the road and I can't see the screen. Is this just for the radio and other apps or will this tune or rather untune the ecm?

Im not 100% sure I follow, but it would sound like you are describing a infotainment system update, I am not aware of the 18 trucks having OTA updates for the PCM or TCM, etc.
