Well, I will be hooking up a knock light very shortly in order to see if the car knocks on 19psi, if all is well I will take it up a notch, and another, till I find the threshold. Wherever i starts to knock I will set it 2psi lower for safety.

The rear O2 isn't a problem, but you can do a quick test to see what effect the other two codes are having. Do a map trace pull in Nissan DataScan and watch what column your on under boost (should be the far right with a JWT ecu). Then do a second logging pull so you can see what the ecu is actually setting the timing to. Compare the actual values with the values in the timing map, how much they differ will tell you what the ecu is doing in response to the codes.
Sweet calum. Thanks. I am going to test the circuit today for the knock sensor. The FSM says that the knock sensor has 1 trip detection, so maybe the knock sensor is bad or something. I am going to look at the circuit today. Hopefully i didn't mess up the wiring job too bad. I soldered all connections and heat shrinked the wires when I was finished to keep things tight. MY timing under boost at 7400rpm is 21*.
ooooo, this is close! The dyno is coming up soon! make sure you vote! Looks like right now it is between 320whp and 340whp, who will be right? Stay tuned!

The codes come on after a while, like 3 drive cycles and the light will pop on. I am getting a Crank sensor circuit/misfire, knock sensor circuit malf, and rear o2 sensor malf. The rear o2 is not hooked up, but the other codes worry me.
Misfire? knock? wtf?
lol i have like the same codes, but none of turbo stuff yet. (calum basic ecu)
