A friend of mine has assembled an 07 LMM with a new ECM. Can I reflash his ECM with a stock tune out of the library and get it breathing? I can get an OS # off the ecm but its nowhere near the stockers in the library. Also is there a way to get efi live to talk to the body control module? Does the BCM have to be reflashed with the ECM via dealer to make everything happy?:Eyecrazy: Thanks in advance for your advice and input!!:master: RR
