Not sure on the normal procedure for the first post but here it goes.
I am new to EFI live and I'm trying to complete a standalone harness for a airboat. The engine is a 2010 5.3 VVT motor that is 100% stock. I'm in the process of building the harness now and It will be a few days before I'm ready to start to program the PCM. When I get done with the harness what exactly am I going to need to do with the tune to get it running?
