E38 ecm vats delete by unplugging bcm

[Jfollower]

"Nothing is impossible to the one who believes" right? Im familiar with the popular YouTube gen 3 (1999-2007) vats delete by unplugging the bcm while the engine is running. Has anyone actually done this on a gen 4 (2007-2013)? Maybe someone has done it on even later stuff. Obviously the purpose of deleting vats is an engine swap type scenario. I'm certain you guys have plenty of experience to answer the next question anyway. Is there any reason an 07 5.3 V8 e38 (tahoe) ecm should not be installed in an 09 (yukon) with a 5.3 for the purpose of this delete? In my case the 07 had a 4l60e trany and no fpdm. I have other option as well- E38 from a 2011 silverado 5.3 with 6L80, or an e38 from 2013 (Suburban) 5.3 with 6l80. The 2009 does have the fpdm already. Basically i need to know if there is a significant enough difference between years in a V8 E38 to hurt anything by installing an E38 which is just similar enough for the vehicle to actually still run. I can only imagine these questions have been answered somewhere, but I just haven't been able to find where.. If this is not the correct place for this question, then please point me to the correct place.
