ecu code

millenia ago i purchased a diablo sport chip to install in my z. i installed it and it didn't work. to my knolage and my dads, the ecu was not reflashed. on the ecu it says the code is kvt5. the dude from the shop said they could reflash the chip to the newest in the series. is there any way i can find out the code on the ecu code like with a code scanner from autozone?

it would be on th sticker physicly on teh pcm, or if you dont trust the sticker have ford scan it
