ok i got everything updated and installed and both the tune license and the 2 vin livense everything ready to go....

read the stock files from both of my trucks and saved them...

open my v7.5 tune tool and try to open the files to modify them and this is the error i get....

UNRECOGNIZED PCM

this version of the EFIlive tuning tool has not been configured to display this pcms operationg system

it does this with the stock files from both trucks...am i doing somthing else wrong? one is an 06 and the other a 07 5.9
