Hooked my 1g up to a datalogger and went off to do some pulls. Now I thought my car was running really rich, but today when it was hooked up, the duty cycle was normal, the problem was the timing was all over. Like from 17 at idle to 45 at times at WOT..so I'm a newb to any sort of tuning, what's my deal? And how do I fix it? (full mod list in my project thread).

Timing should be all over the place. There is a 16x12 timing map that it uses for a starting point based on RPM vs load.

Alright, I also have knock, at one time it hit 29, Idk if my crappy Chinese 16g is spooling right, it seems like boost cuts out, it's getting plenty of fuel, but doesn't pull all of the way through. Also there are no boost leaks, just fixed all of them.

What are your A/F ratios, ignition timing, rpm, and boost when it knocks?

Rpm=3687, injd=30.4%, knck=26, tps=39.8%, map=2.77 bar, tima=19 degrees, injp=9.9ms. Thats what my data logger read. Boost is stock, just off wastegate.

Do you have a wideband to read the A/Fs? Why is the TPS at only 39.8%, does it goto 90%+?

When I got another big spike like that, the numbers were around the same.

Don't have a wideband, it's on the to buy list. The tps at one time was at 99.6%, at 5093rpms, 70.3% injd, with no knock.

Does it only knock bad at part throttle?

sounds like phantom knock to me. at part throttle like that there really isnt any reason for knock as far as im aware
