Not that it matters, but i'm kind of confused. They call it a chip, makes me think an add on like the jet chip. Yet you needed to send them your pcm, so is it really a flash.... To answer Tokyojoe's question...you don't, unless you have a second pcm. With your vin programmed into it. And if anybody does get their pcm flashed by B&G or any other shop, i would recommend getting a second pcm. The pcm returned to me by B&G had all the DCX firmware version stickers removed and a big yellow sticker that said among other things "for offroad use only". Unless you have a mod friendly dealership (which mine isn't), throwing the stock pcm is a good idea before sending your kj in for service. The dealership may try to blame it and void the warranty for the work. It also protects against a conscientious tech seeing a tsb out and flashing your new pcm with a stock update; writing over your expensive performance flash.
It also could be a "PROM" chip,which reqiures the disassembly of the PCM to change.
