Okay, been doing some research and found out that i have the old style PCV valve (the one that was recalled). Going to install an oil catch can tuesday and see if that fixes the vacuum situation

That is what i have on my car. I can read the voltage from the in and out on my sensor check. Could it be because its not soldered? I crimped the connections, could it also be that i am teeing my boost guage off of the map sensor?

Ok i will do that. How will i know if its bad? Will it constantly spit out oil? As for the neo,

That thread talks about MAP sensors. You were talking about two different types of MAF sensors... noticed the P and F... one is pressure, the other is air flow... Karman and Hotwire are both different types of MAF sensors that you were talking about - your Neo should be wired and configured to run for a MAP sensor...

PCV generally get stuck open or closed, more often than not, they get stuck closed, which would not cause your issue... stuck open, potentially, but still not likely...

Also my exhaust cam cover side is to atmosphere ( kinda looks like the pcv port but opposite side) should that be connected to the catch can while im testing the PCV?

I see!!! Ill take a look at it today. The neo manual says "hotwire, flap, and pressure sensor" that is the one i used to wire it in. So how do i adjust my settings on the neo because In the sensor settings i can set hotwire and pressure. So how would i set that? I mistaked hotwire for being a map

The wiring is the same/similar no matter what you use for air metering, but you should set the sensor setting in the neo to pressure...
Correct, hotwire is not MAP, it is MAF - it heats a wire inside the MAF and then measures how much power it takes to keep it hot - the more, denser air that flows over it, the more power it takes to keep the wire hot... MAP is just a pressure sensor...

Awesome, thanks a lot mitsuguy, youve been a lot of help. I set everything up right yesterday, it will start easily and then cut right off. I believe its my fuel pump relay since the 13B rotary would have to give it signals to keep running

Okay wired the relat like it should have but that wasnt the problem. I suppose its the apexi neo. I checked the firmware and it is 1.020! But that shouldnt affect the map because they mostly upgraded it cuz of the karman right?

Ok so i think i may be on to something. My injectors are 550cc from a 2jz and my ecu is reading it like they are stock. I dont have an afpr...yet. Could this be an issue? It revs fine when its just the ecu and no apexi neo connected

The Neo intercepts the MAP and gives the ECU a slightly different reading... with all adjustments on the Neo set at 0, it should act no different than if it weren't plugged in at all... I am not too familiar with all of the Neo's settings, but I would bet there is something wrong with one of them...

Forget the Karman. Your car uses a MAP sensor and the Neo needs to be set to read as such. Its primary use is to compensate for the increase injector size by manipulating the signal the ecu gets, as Cody has already stated. I'm willing to bet that its idling and not staying running because its expecting to see a variance in voltage at the Neo because it still thinks is hooked to a Karman sensor.
