So does anyone have a page that i cna look at to see how to setup the VCT properly.

Datalogit costs money AFAIK Why would I want to spend EVEN MORE on an aftermarket ECU to tune it? Tuning software should be free! You can DL Microtech, Haltech, LINK (IIRC) Wolf, Adaptronic. It's all free. I'm not paying $1000 for an ECU, then having ot pay more for software, what a ripoff idea! When you buy an aftermarket ECU, everything to tune it should be supplied (Or be readily available for free)

Has anyone managed to set the VCT up yet on the RB30/25 combo?

Corinne says: As much as I'm not a fan of the PFC, you should get one. - That's because you can't tune them properly wink.gif You should use one device to control one element, at the moment you're using 2 devices to control one element. Not smart. They tangle each other up. That and you may have lost your map in the SAFC - SAFC's are shit to tune.. they are very rough.. you can never get those flat spots out of them. Corrine, PFC are frigging annoying to tune off of that little hand controller, especially when attempting to use map tracer at the same time to look where the engine is sitting, and then adjusting that! And I never said the SAFC was good, I said it was possible he had lost his map from it.

I have the exact same issue. Especially the reversing and then braking issue. My wheel alignment guy found the problem. My front upper control arm bush was shot, allowing the control arm to float backwards and forwards into the car body. He noticed it via the tiny amount of rust where it was hitting and slight scraping/ding.

17mm Hg, my 33 idles at 20 - 21 mm Hg, and so do a shit load others I've seen... Sounds like you have a vacuum leak somewhere personally. Also, ditch all the little tuneable things, and get one big tuneable thing. As much as I'm not a fan of the PFC, you should get one. You should use one device to control one element, at the moment you're using 2 devices to control one element. Not smart. They tangle each other up. That and you may have lost your map in the SAFC

I might meet you guys there if I remember.

If you still have motor, box, ecu and loom when you're about to send it to the wreckers, let me know.

I'll rebuild it for $2000. *Gets out sledgehammer, gaffer tape, super glue and 100 sheets of paper for gasket material*

Clamping brake lines, just like fuel lines can be dangerous. They are known to split. Personally, if you're going to clamp them, be prepared to replace them. As for the shims. They are only used to prevent brake squeel. There's no worry at all if you don't run them.

How much boost are you running? Does the GTSlink only run one rev limiter? There's no soft limiter? No boost cut? No flat shift limiter? When it hits the "rev limit" (What you're currently experiencing) is it like a miss fire? If it's getting richer and richer, why don't you try leaning it out? ( by rich I'm assuming you're talking 10:1 or 11:1)

Intake plenum with throttle bodies sold with the head I'm guessing?

srs. coilovers (good ones) are often worth a mint.

Hey all I need to find somewhere that does the front, passenger side, upper control arm, forward bush, where the control arm goes onto the car body. My bush has decided to die, enabling the upper control arm to "float" forwards and backwards. I have been quoted $200 for this bush alone, from pedders. And find this an unbeleiveable price. So, are there any others?

Sounds like crap tyres. I'm running a GTS-t R33 with GTS4 springs in it. So stiffer springs in the front, which will create more understeer then stock springs. And it only MILDLY understeers. To me, it also sounds like poor driving (I'm not having a go, I used to do it too) It sounds like your starting to feather the throttle way to early (I internally yell at myself everytime I take a corner so that I don't do it) As you start to feather that throttle, you're lifting weight off the front tyres. Which is reducing traction. Keep off the throttle till you're through the corner further, wait until you can SEE where you want to go, and then start to wind the throttle open. And no, more throttle does NOT equal oversteer. Go do a skid pan day. It lowers the grip limits immensely (On concrete) and it shows you exactly how the car handles under breaking and stepping on the throttle and different amounts of steering (No, more steering won't make you turn in further all the time!) But a start: Get some grippy tyres.

To test it, you really need the car to be misbehaving under "normal" conditions to begin with.

Without viewing video. I'm thinking: Remote turbo location. Somewhere near the rear of the car. Think lag. Cops will just follow long piping and find it. Plus your car is turbo from factory I'm assuming (GTS-t) so if you take the turbo off, the car is STILL on the banned list (As all of a sudden you've done an engine performance modification.)

The whole in the boost controller, is to allow air to escape when you close the throttle. This then allows the wastegate to close again. Also, if your boost is dropping 5PSi, it isn't the hole doing that. That's ALOT of pressure to loose through a tiny hole. By a 5psi drop, the spring and ball should have closed, all air should vent out, allowing the wastegate to close, and boost to climb again. It sounds more like your turbo can't keep up.

If it leans out. You could blow the motor. If there's too much timing, it could detonate the engine.

Drive around with it cold Let it run like a billy goat. As soon as it gets good, jump out of the car. Unplug the Coolant temp sensor that heads to the ECU. This is the plug that sits on the top radiator hose, and has TWO wires going to it. See if it runs like a dog or not. If it does, most likely CTS.

Did it happen as soon as you serviced it? Sounds like coil/plug break down.

Sounds like a wiring issue. Car is actually making boost right? Now, you have an external boost guage right? And it shows 6PSi? If you get the car to say 3PSi, does the AVC-R read 00mm-hg or does it actually read something less? If it's less then it sounds like a setup issue. If it's 00mm-hg, then it sounds like the boost sensor is sending out the same signal as soon as it hits boost. Like it's maxing out.Strange.

Your understeer could also be that your car may want a little less front camber once that tyre has heated up. Generally, if a tyre gets too hot, it gets slippery. Not sure at what temp this will occur on a slick.
