Hi all

It's my first time posting in sau as i recently purchased an NA R34 with an aftermarket turbo.

First of all, can anyone recommend a good tuner (preferred specialised in skyline bnr34) in Melbourne? I would be getting the car retuned after fixing a problem that it currenly has.

Secondly, so the problem it has now is that it can rev upto redline on P mode but when driving the rev caps at around 3000-4000. Up to this point i think that either there might be something wrong with the AFM, or i have to install the aftermarket fuel regulator and fuel rail back into the car as i think it could also be the problem from the fuel pump. However i am no specialist in cars so if anyone of u guys can give me anyhelp that would be greatly appreciated.

The previous owner did told me about this rev-capped problem and gave me the aftermarket fuel regulator and rail, however i am not 100% sure if that is the solution to the problem so i am wondering if the problem can be easily fixed by a professional tuner/mechanic incase if it is something non-trivial.

Also, both the fuel injector and fuel pump are aftermarket and not stock, the AFM i believe is a Z32 AFM.

Cheers

Also that car sounds butchered.. stock RB25DE ECU with a turbo slapped on it.. don't dick about with the fuel reg or mixing and matching shit without an aftermarket ECU or at least a piggy back (as you have an auto)

Sounds like you bought a problem. Which is why the guy sold it.

Prepare to open your wallet.

hmm prehaps not as bad as u thought,I've had my mechanic looked into it and he thinks there's no big problem but it just take time to find this rev-capped problem,which is likely to be either afm or fuel related.

The car has GReddy emanage ultimate ECU since it's an auto as well as many other mods with over 10k receipts, so I am wondering would a professional tuner be able to diagnose the issue better for me?

Yes a tuner would be your best option

Sorry my bad for creating multiple threads.

Also, apparently Chequered Tuning doesn't tune emanages anymore. Is there any other suggestions? Thanks in advance.

I would suggest getting an Adaptronic e420D and splicing it into your loom to control injection/ignition and letting the OEM ECU control the automatic box.

That "rev cap" as you call it is actually a TP Load cut.. your ECU is going "wtf.. why is there so much air going into the motor, I'm cutting fuel"

Talk to Trent, tell him the bastardised setup you have and someone from SAU recommended using an Adaptronic e420D to make it boogie.

I tried, unfortunately the guys from Chequered Tuning said Trent wont be able to talk to me over this matter, as apparantly he doesnt get involve with emanage anymore ;/

      LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

      Jacks that fit under GTR lips that can reach the subframe?

      By GTSBoy · Posted

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
