- available extra tables for transient fueling, lean cruise (via .cax file).

Disadvantages:
- you have to manually copy your old tables over to the new file, takes about 2 hours (3 with beer).
Looking into this for a 2000 LM7 Chevy Silvarado which is 12205612 to 12212156, there's also a 2002 LM7 Silvarado TuneFileDepot so may be a good start/not have to do all table swaps. Seems they are all LS1b but some are 475, 474, 473? Is this an issue?

Since license is to PCM then should be fine to read it and be able to differenth with differant OS?

Full flash? Is there an issue with some vehicles and doing full flash in vehicle? I've read, don't know if true some full flash are better done on bench because of other modules in car trying to connect during this procedure creating a brick?

Just looking for tips before I create a brick...
