Hello Pancakeman,
I received your message and will do what I can to help you with whatever questions you might have. Unfortunately I have no knowledge of whether or not it is detectable as you will not know if it is till long after. There are a few variables that it looks for in the modification of your system to tell whether or not you are using hacks. It is Aequitas proof which gives you the benefit of the doubt behind detecting the hack. More or less it is up to the hacking individual whether or not they will be caught.
Side note: ESL Wire is a form of Aequitas which collects data in hash value and sent to the ESL servers, different from that of its predecessor I believe.
Side note: HL2 esp works well if you are more accurate at aiming and would not need an aim-assist that would come from the Multi-cheat.
I hope this answers your question, if not, another more knowledgeable member/admin will answer this for you.
