Nice to hear that you use EFILive frequently - it is a very user friendly tuning software. However, the necessary skill sets for a dyno (airflow) tuner, and a conversion (component compatibility) tuner are very different.
There is a little more to it than that. This is where knowledge of potential conversion issues comes into play. Your 2014 Z28 (LS7) used an E38 ECM with OS 12656198. The same E38 and the same OS was used by both L99 and LS3 Camaros in 2014. The LS3 was mated to a TR6060 manual transmission - just like your LS7. The L99 was mated to the 6L80 automatic transmission - so this tune is the resource that you will need to make things work. For Camaros, 2014 was the first year that the 6L80 and 6L90 TCMs used the same OS - so you are fortunate that this conversion project is a 2014 model.
Where do you go from here ...
I would suggest that you follow Joecar's advice from post #2. Obtain an E38 tune from a 2014 Camaro with the L99 engine - then copy over the relevant parameters from your LS7 tune into the L99 tune. This will not be perfect, but it should get you going such that you could then dyno tune the airflow models (MAF & VVE).
Another option is to swap in the relevant segments from the L99 tune into the LS7 tune - but this is not recommended for most tuners. There are several tables and parameters that would need to be adjusted after the segment swaps - which are not available in any tuning software.
