you can check the ecu to see what the fault was. I'm not sure how its done with r34s but someone else might know. Might be the same as for r33's, if so, search it cause its been posted a few times. If you take it to nissan they can check it with datalogic and see whats the problem. Could be nothing...

Hello,

More than likely it is O2 sensor, this happend to me once.

But do a check.

The mechanic at the time bridged some point up with a wire and the dash lit up several times to

notify us of the fault and which sensor it was.

I am not sure if this is the same for R34's. :)

i think i need to take it for a tune?

congrats on finding a PFC where your standard ecu should be :ermm:.

Yep, get a touch up tune just to make sure everything is ok.

With a PFC the check engine light generally flashes if the knock reads >60. I'm guessing it knocked a little when you floored it and put the engine under load a little. Just get a touch up dyno tune done :P.

I had this problem when I first picked up my r34 turbo from the dealer.

He did the diagnostic and it turns out it was a speed controller. He said just keep driving it till the part comes in... Then 3 weeks later the warning light switched off and no problem since... Though I have had the speed controller replaced just in case but it is amazing what sorts of warnings this advanced electronic controlled cars can give you.

Battery was out of the car for one week whilst a body kit was installed, then the driving to work on the F3 in Sydney to Gosford car turns off and does some sort of emergency breaking, turns out one of the battery cells had died and was only causing a fault occassionally when more then normal power was being consumed. Naturally this was a wet day, so had headlights, wipers, stereo and the driving aids were occassionally kicking in.

Anyway, moral of the long and pointless post :ermm:

Find yourself a good "import shop" that you can build a relationship with so that you can have problems solved easily and without being ripped off or car damaged by a mechanic who does not work with imports.

Also just incase you didn't know where your diagnostic plug is, it is below the steering wheel to the right it has a little latch where you can unplug it and then plug it in to a diagnostic tool or workshop... or even one of these great new toys from greddy I seen in the latest high performance import magazine.

Drew.

      R32 GTR EV? The leaf of the Godzilla's!

      Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.

      Ok so I have sorted everything with my uniclutch and  i can offer up a bit of feedback and some things that might help others.    I found problems with factory damper line. Weird shit and had trouble with peddle adjustment    I used this https://au.gktech.com/products/r33-gts-t-skyline-braided-clutch-line?_pos=2&_sid=22b01b9b9&_ss=r Also when adjusting peddle leave a bit of play. You can get into a over stroke condition easy.. Make sure you can push the slave forward after adjusting to confirm fluid can return to master then you will need to pump it up heaps…..not sure why but that’s how it is.    last thing the splined adapter is machined perfectly. If your input shaft is old like mine was I would put a bit of valve grinding paste on it and stroke it like a 15 year old. Just to give it a tad more clearance and to better match it to the spline.    reason is on a near flat shift I have had situation where the peddle returns a millisecond after you lift from the clutch. No slip or anything but I reckon this is due to tolerance on the spline being way tighter than stock clutch and binding for a sec. I think this will go away but also my spline was old. Box is old so I guess I should have checked better. It’s a super neat fit.    it feels light as and holds awesome without any noise

      Was that Australia Delivered Duncan? Does it have siren etc?   I used to have remote start on an old 32 two decades ago, it was a cool feature. I used to wake up early in winter for work. Start it and by the time i was out the door a few minutes later the engine was warmed up and the heaters had the car toasty. It was great.    I don’t mine the ambience lighting.  I drive a western star and it has footwell lights and ambient lighting and it’s great! From the pics of seen of them installed in a skyline I think it’s a nice touch
