What are some of the reasons for doing a full reflash?

First off, you can't do a full flash on your truck, since its a Bosch ECM. They can do Cal only flashes. Second, full flashes are for switch operating systems like to a custom operating system in the LB7 and LLY's for DSP2&5. :)

Ok well the reason i asked was today i tuned a buddys truck which is an LB7 and i seen the was highlighted and was wondering what it was? So if i was to just do a simple dl a tune into his truck i wouldnt have to do a full reflash?

Ya, you only need to do cal only flashes for normal tuning. If he want to change OS's to DSP2 or 5 then you would use a full flash to do that.
