Hey guys. I'm looking for some help on this please. The car usually runs around the 23 psi mark with no problems. It's like one day it was fine then took it out again and now it runs at a perfect 16 psi. Nothing unusual happened while driving either. The car still runs fine but at 16 instead of 23. Nothing was touched on the car or adjusted. I have taken it out a few more times since then and every time the same thing, 16 psi? Boost is controlled via a gizzmo ebc. The only thing I have tried is that I checked and re checked all joiners and clamps. I even changed a couple of silicone joiners that I felt may be suspect but still the same. Any help would be appreciated. Thanks.

Is it an internal or external gate setup? it could be running gate pressure if the EBC isn't working? Mine does that when it plays up....

It's running internal gate setup. I did think that the ebc may not be working but I can still hear the solenoid working its little heart out, so I assumed it should be working but I could be wrong.

Unplug the boost controller and see if it still boosts at 16 and feels the same.

If it does still boost at 16 then chances are your controller is not working so borrow a mates controller and test it.

Sounds like its just running off the gate rather then the controller

Turns out it was the EBC. After initially receiving a dodgy solinoid when I first bought the Gizzmo and now this, I have ordered a V2 turbotech. You've had two chances Gizzmo, now you can get stuffed.

At higher boost levels every psi is important so if your gunna go in the cheap with a manual valve make sure it's setup 100% as you don't want to lunch your motor by going cheap with boost control.....

In saying that I spent fkn heaps on a HKS controller and have issues so that kinda stuffs up my point a bit :/

Hi Mat. I've tried quite a few different manual controllers and I must say when these turbotech products came along, tried one and was amazed. I've currently whacked the original version back on for now so hopefully the V2 is even better. As for going the cheap I don't believe going cheap on the skyline it's just a bonus it's that price. They could of charged triple the price and I would still buy it.

I had the V1 and it was OK, it did tend to bleed off boost though... In saying that, they are a good bang for buck controller, have you got boost cuts etc setup in your ECU? Just for safety?

Mines setup so if the boost controller or gate fail for some reason it'll dump fuel in, pull timing out and then if I haven't backed off it will boost cut... So it's pretty safe ;)

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • 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!
    • 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.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
