Hmmm... I run the standard AFM too and I ping as well!

At high boost, heavy power usage.

My z32 is imminent (thanks to Philip!) and I'm doing a fuel pump (either a 040 or 984 - doubtful whether a 044 is in the cards :P

Sooo... I'll get back to you guys with just the z32 and Bosch.

Injectors, reg. + plenum is some while off for me I afraid.

Mark - you need to get with Northside sometime!

sounds good on paper.

haha? or just buy the Mines R34...that may fix it for good

i mean common, he is looking for a cheap solution, i suspect?

not to fork out $2500+

I've already got the fuel pump so another one is not needed.

I've also got Inasnt's old blitz BOV in (at last).

I've been too busy to do anything with my car, looks like i'll be busy on the weekend too - gf has an assignment due which i'll be doing. working 6 days + uni assignments = not much time for anything else.

Killer: where can i change the idle? my car is idling at about 600, shouldnt it be closer to 8 or 900?

maj: nope, i havent cleaned the injectors, but a week ago i bought some of that injector cleaner from a car store (just for the hell of it) and poured it in the tank.

Tony: I have a couple of times. I've been to meets/cruises starting at burger king and chatswood.

Inasnt,

Are you getting your powerFC through Nengun? I got mine a few weeks ago through him and cost me $1600 delivered. I put it in myself and then (as you know) got it tuned last saturday.

What do 550cc injectors cost to buy + install? I'm thinking of ruling out other stuff that could be wrong before spending more money. I guess ive spent about $10k sofar since I bought it less than a year ago.

What I dont understand is - why would the commander report that the injectors are at 72%. If there is a problem with my injectors wouldnt it read close to 100%?

Majanal,

I like to do things properly so I might have to get another AFM and injectors after I rule out other possible causes.

yep getting pfc through nengun for a bit cheaper than what u paid as its a second hand pfc and new handcontroller!

As for injectors the cheapest i have found is around $170 each for sard ones. I am getting all the parts together (around $7500) and getting it all installed at once.

We can high flow stock R33 injectors to 600-660cc capacity for $150 each. It’s all done on a flow bench and importantly all matched to one another so that all cylinders receive equal distribution. Removal and replacing would be another $200 but I’m sure a lot of you guys are good with the spanners and could do it yourselves :)

Btw, I have heard pinging on the dyno yet the power FC commander only showed a knock value of 27 and the engine check light didn’t come on. Go figure. Also Sydney kid has a valid point with the computer sometimes accessing the wrong load point in the tuning maps. So you might get an anomalous reading once in a while and the car might do funny things.

how long would it take to highflow 6 side feeds?

MRK25T, those dynos look ok to me, nice result acutally. Have you checked your AFM peak voltage yet? The reason I ask is because that is exactly where mine hit 5.1v (max flow) when I first fit and tuned my power fc.

If your car is idling fine at 600 dont worry about it, I think stock is 660 rpm if my memory serves. If it isnt idling correctly, take it back to the guys that tuned it.

If you must mess with it, the idle is in the settings menu. Just remeber you may have to adjust the deceleration fuel cut recovery rpm first (setting above the idle setting), as you have to have at least 100 rpm between it and the idle.

That is exactly what I am talking about! Now if you go into the etc menu (I think) you can disable the check engine light for the AFM. Take the car out again, and see if it still flashes. Alternately, check on your peak hold and it will show you what is maxing out, but I think this is the problem, esp as your injectors are less than 80% and you dont have any noticeable detonation.

5.1v (or 5.115v if you want to be exact) is max flow on the AFM = check engine light flashes.

    • 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.
