Can anyone look at these logs and let me know how they look or what I can do to make them better. I have attached maps with stock plugs all pulls were started in 3rd at 30mph
HKS M45IL plugs gapped to .024 only engine mods are K&N intakes and Add1 OCC

Interesting that on Map 0 you got (minor) timing corrections, and less minor ones (3.8s) on Map 1, with stock plugs. Guess the colder plugs make a difference even at low levels of tune.

For your Map 1 files with HKS plugs, one file has some cylinder-specific corrections of 3s which is where we start to care, but the other is all 0.8/1.5 which is fine. Map 2 you have some 3.8s, 4.5s, and even a few 5.3s in cyl4...assuming you didn't skip changing that plug, the fix is higher octane gas (ie 93 if you're running 91, or ethanol mix) or stick to Map 1.

You also have a LastSafety value of 255, but I'm not sure what that code corresponds to, or whether it's recurring. You could email BMS, or clear codes and see if it returns (could just be something historic).
 
All plugs were changed and gapped to .024 I will pull plug 4 tomorrow and double check that plug thanks for the input
