Yes the car was up to operating temp and running and it was steady at 18mm HG. There was no change in idle speed and no change in 02 reading to indicate additional hydrocarbons, i used consults to dignose.

I have tested the ic form the turbo to TB, held 50 psi no loss.

I did also spray all the IC connections and IC itself, no change.

Did you pressure test the plenum? Open the throttle body next time you do the test so it pressurizes the plenum too, so if there's a leak in there you should be able to hear it.

Well, myself having not actually had a look inside an RB before, in theory that sounds correct. But should they be both open at the same time at any time?

You don't have an adjustable exhaust cam do you?

Either way, If there's a leak somewhere, then wasted air = wasted fuel.

there is a certain amount of valve overlaop on the exhaust stroke from memory, i will rotate the cams to get the beast seal and see.

I agree that wasted air = wasted fuel, but it's a bitch trying to find it. LOL.

i will get another mates guage just to make sure mine is correct. The stock guage sits about half way between the bottom line and the first line from the bottom. so about -5 or what ever it is.

Green means GO, Red means Go SLOW, lol.

Well my drive to work is 8 minuts at best, and i live in hobart which is hill central so it's hard to stay of boost all the time.

I do give it a squirt now and then, but not like i'm going sideways evewhere.

When my wife drives the car, she gets no better ecconomy then me, so either the car is screwed or she's a lead foot. LOL.

wind your boost down. you are using more fuel because you are running higher boost. the more air you put in the more fuel that has to go in to keep the afr's the same. you would probably benefit from a tune, but you still won't be able to get the fuel economy of someone running 10psi because they aren't putting as much air past the afm.

Arround touwn i run 10 or 7 psi depending, and ecoconomy stil shit. The tune was done at 15 psi and rechecked for lower boost levels and all showed to be fine.

Anyway tune next week so interested to find out what it is.

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.

Who the heck tunes off the hand controller? You use the datalogit, a laptop and a wideband to tune them properly.

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
