Sorry mate, fucked up the simon says step, will release patch tomorrow

Can someone please help me. I down loaded the T4M [R49] patch and it works great. I no longer have to lower texture settings in order to play certain maps now and overall works good. But one feature it added to my game that I absolutely hate is the aim assist feature. No matter if I aim or shoot with my crosshairs near a zombie, it auto locks onto them and it is really annoying. I like no aim assist. I want to remove this feature as it causes me to miss shots sometimes and i find it difficult to headshot zombies as well because it just auto locks onto their torso. Someone please help. I want to remove this. Is it a certain command I can input?
