Thanks Lance,

I just want to know is this Diagram correct?

Green line from the solenoid = The one without the restrictor, point to the battery = line goes to the wastegate (Green line)?

If the diagram is not correct, cna someone please amend it / edit post so it *is* correct?

I have a similar plumbing problem... my GTR has been mucked with.

Diagram is good for those of us with a pile of parts on the table :)

+1 for that I've been avoiding my boost lines for a while now although I'm glad to see that the evap purge lines that run behind the rear timing cover are only emissions stuff cause I forgot to put them back on before setting all my timing up and I'm not taking the timing belt off again just for that.

Thats not actually correct,

the actutator lines should only be plumbed into the boost solenoid ( as apose to also being plumbed into the "bottom of collector, Boost source" like in the above picture)

Not on a STD GTR.

That diagram look right to me. If you remove the pill it can bleed more boost source from the actuator line - hence increasing boost.

The blue line bleeds off to the inlet of the turbo to allow more boost when the plug on the solenoid is pulled enabling the higher boost level

i stand corrected... lessons learned

well according to that diagram theres a direct line between the manifold and the actuators, somethings is not right there

pretty sure the green and blue are ass about in the top half of that diagram

Your wrong. Thats how they came out. The solenoid is only a 2 port. Meaning that if it is not energized the signal that the actuators get is the full signal from the +ve side of the throttle bodies(hence minimum boost or actuator pressure).

When the solenoid is fully energized 100% duty then you are bleeding the maximum amount of boost the solenoid can flow away from the actuator hence reducing the signal to the actuators and increasing the boost. If you want more boost then removing the pill will allow more flow and reduce the signal to the actuators even more.

If you hook it up the way you have suggested then at 0%duty you will have no signal on the actuators hence shitloads of boost. Follow the diagrams guys and you will be sweet.

    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
