No, you have to run a separate MAP sensor on Power FC purely for the boost control side mate, the boost control does not use the engine load MAPs which are tapped into the 2 X AFM signal wires. So on a GTR d Jetro you end up having three Apexi MAP sensors on an RB26.

Where can you plug that into though? As the plug for it on the ECU is already used with the other map sensor.. and I am running a hks t51r single .

I don't have any 2 pin wire there to do that! That's the problem. The gts doesn't have the same boost solenoid as the gtr. Has one over by the turbo. But as that loom as been changed for the gtr along with the battery connector loom I don't have that either. All there is is that 3 pin cable where the correct 2 pin should be!

Why is this so hard?

Run a new 2 core cable from the ECU adapter out to the engine bay and put a matching plug and socket onto it and the boost solenoid. You know, manually, like with your hands. A little actual wiring, not just plugging shit together.

Would rather not have to cut up the ECU harness that's why. Would rather of used the factory wires if they were there. But as they are not I'm asking for help on other options. Would rather replace my broken stand alone boost controller than hack up the harness lol. Only went for the Apexi as I thought the garage had fitted the whole gtr loom as I supplied them with it including the fuse box side of things. But looks like they haven't. Even though the battery cables have been changed for the new ones.. that's why I was confused in not seeing the factory 2 pin for the solenoid.

to be honest, I think you are best getting someone to do the install for you. The process is reasonably straightforward but I guess you aren't confident to do it so best get some help rather than get it wrong and blow your motor up

The connection from the PFC to the solenoid is 2 wires, but it is not plug an play. Any auto electrical person should be able to look after that part.

You also need a pre throttle boost source for the map sensor, which needs 3 wires back to the ECU too.

I'm more than confident in doing the work. Done most of the work on the car myself. And the kit is plug and play if I had the stock wire as it has the same plug. Even if it wasn't the same plug I can happily change them to ones that match. The problem is I don't have that wire to do so. And would rather not cut up a perfectly good harness after having problems with a hacked up one from its life in Japan! What I want to know is exactly where on the loom the cable for the gtr stock boost solenoid is. And if I can in even fit the gtr loom from the fuse box side into my gtst and it work. Everyone seems to be ignoring the questions I have asked! I know where it should be fitted And how to fit it. But I don't have that option so need advice on what else I can do.

It's not on the engine loom. It's on the driver's side engine bay body loom. You don't have it. The wires are not there. Stop looking for them and start plumbing in the cable that you are going to need.

Plus, you're not having up any ECU loom. You're just going to stitch 2 wires into the PFC boost controller.

This is wrong. Because, as I posted MUCH earlier

There is no "standard boost controller cable" on an R32 GTSt. They didn't have a boost control solenoid, so......they didn't have a cable for it.

The Apexi solenoid basically needs 12v to one side of the solenoid (usually powered from IGN pin 45) and then switches to ground at the ecu at pin 25 for the pulsing of the solenoid to bleed air.

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
