I have a 2005 suburban with a 5.3 that I am dropping a 2000 LQ4 6.0L (with up grades) Into. The 6.0L came with an ECU as well. With the whole credit costs which ECU should I unlock or does it make a difference?

You must use the computer already in the suburban. The 2000 computer is an older P01 and you have a P59.
So you also must keep drive by wire. Basically you are just doing a long block swap and using all the intake/fuel rail stuff from your 5.3 engine. License the 5.3 computer and then just tune it from there. Can probably find a stock 6.0 Yukon Denali file from 2004-2005ish and swap a bunch of data around to make it like it was there from the factory. Mainly just the idle settings, idle airflow, MAF/VE data for fueling and timing tables. It should run alright just doing that.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Thank you. Yes It is pretty much a long block swap but I am putting in a TBSS intake which is still "fly by wire" so should be good. Appreciate the help!Originally Posted by 5FDP
