Yeah, whatever. I don't really care. I don't want to drive it really until I get some of the bugs worked out.

Uh... No new updates. New belt will be here on monday. I bled the intercooler system in the mean time. On the first drive, the intercooler had maybe a couple cups of fluid in it. The ambient air temp was like 98 degrees (like 12 in the morning), and my IAT2 was 164-167 degrees. After bleeding the intercooler, ambient air temp was 113 (mid-day), and IAT2 was ~125-130. Huge difference. Still gotta figure out WTF is up with the knock sensor

Ported blower, dual pass intercooler mod, and cobra HE. Intercooler and blower were cyro frozen (33% better heat dissipation).

I'm getting 2 codes for the knock sensor, 2 for the front o2 sensor, and 1 for the ac pressure sensor.

Might some dumb, but I am assuming you have the right connection for knock sensor, and also on the right spot on block?

The multiple codes for the same problem are probably a pending code and a set code. They both mean the same thing so disregard the pending code as long as it's identical to the other one.

I'm almost positive we got the knock sensor plugged in. So I hope its not fuct. Also I think we just forgot the plug in the O2 sensor.

my buddy with the 98 gsx had the same issue when he got his motor built as well just something small an seemingly easy ends up always being the issue, in his case there were boost leaks and an issue with the throttle body

Eh, you don't need an o2 sensor...when you get high just standing behind the car, you know it's running rich enough.

Actually, its learning pretty good. It now idles around 13.8-14.2 arf, much better than 12.3-12.6! I might need a new O2 sensor though.

Since when did you start working out? You realize you have to hit puberty before it really pays off, otherwise you don't have the testosterone levels to build real bulk.
