help eliminating this knock
so, experiencing nasty shift knock and need your advice guys. checked and nothing is hitting nowhere under the car. I think it's caused from timing jumps, but don't have that much experience to deal with it myself, therefore need your help 
in the zip below, there are two logs - one with NLTS shift and second with fast shift without nlts. not a big difference though. and the rom itself
any help would be greatly appritiated. thanks in advance

im too new to mapping to see whats weird
(also the VIII xml is 10x bigger than my tiny IX one so dont know half the tables)
but I see you have 800rpm set in the NLTS settings and it seems wrong, from what I read here you are supposed to set it near your actual shift rpm drop
try setting it to 1500rpm or more should be better
it's not supposed to pop and bang or hit the limiter, at best I've got a smoother and softer shift than with regular lift-off
NLTS knocks on a otherwise knockless map so you shouldn't have it active while trying to fix your shift knock problem, it's not helping and it shows in you logs
good luck !
