tuning Options

[eclaser353]

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

your O2 is .64v under load?? That's real lean, o2's should be .8 or above under load (WOT). Is the o2's oscillating properly?

I would turn down the boost first and richen up the mAFT, especially at WOT. I'm not too familiar with mmcd but what are are your fuel trim (lo, med, high) running at?
