tuning

I have a 1g and just recently put a maf/maft on it. I have a big 16g with 510 injectors supra fuel pump and the rewire kit for the fuel pump. I still have the stock intercooler. I am using a palm m100 with the mmcd for logging. I have never done any tuning before. I have the maft set at 4 on aux 4 on base 1 on idle 1 on mid and 1 on wot. On the logger im seeing sometimes 43 counts of knock. It is usually at low rpm. I just did a log and got 28 counts of knock at 1875 rpm. The tps is at 28.5% tima is at 16 o2r is at .64 v the fto2 is at 100% and my mafs is at 232 hz. It seems like it happens when i first star to get into the throttle. Anotherone i got is at 6968 rpm with no knock tps is 58.2% tima is 19 fto2 is at 100% mafs is at 1599hz. Im not sure of boost but i have seen it over 20 psi. Im not sure what i need to do with the maft to get rid of the knock. Can anyone help out with the tuning of this thing ? thanks
