Im looking for a computer for my 32 Gtst but it is so hard to find anything that isnt a big $ racing set up.

I dont want to flash the chip cos its expensive in the long run (retune everytime i change somethig) and no handset with all the cool stuff on it.

Apexi power fc is what i want but its very hard to find, nearly got a new one from a bloke in japan, but it was put in some show car, so close yet so far.

Does anyone know about Link G4? They say i can get one but ive never heard of anyone using one on a 32 Gtst.

I think the motor is really lacking without it, considering the cams and turbo are upgraded.

uh... no matter what ECU you have, if you make modifications you will need to have it retuned.

That is part and parcel of making modifications.

The same G4 plug in Link suits the R33 or R32 but Nistune will be a cheaper option. Any ecu needs to be retuned when you mod your engine.

If you have already upgraded the turbo and cams with the stock ecu not only are you missing out on the potential gains you are also risking your engine.

I think he was more talking about the need to pull and burn chips to achieve that retune, which is the most annoying part of chipped ECU tuning.

Hmmmm...

Well shes running rich and i never rev it over about 5000.

And i live in canberra so im limited to what the local tuners can tune, waiting to hear back from them.

I would pay for an apexi.

Well see about nistune.

Nistune.

and if you want to see a display - get an ecudatascan device.

I've got that combo in my R32.

http://ecudatascan.com.au/store.html

it can display like 10 or 12 parameters from an R32 GTST.

Also can be a GPS

and do lap timing for tracks and you can actually build your own track image in to it etc etc.

Cant get Nistune done here, i got quoted $3200 for a new Haltech setup with map sensor and tuned, im sure its good but too expensive for me. He also recommended bigger injectors, more $$$.

Maybe i have to take it to Sydney for a Nistune?

Is the Nistune up to the job? How well can it be tuned?

This is turning out to be much more difficult than i thought, so ill tell you whats on my car and maybe you (Sydney tuners) or someone you know can tune it properly.

R32 gtst manual (converted from auto)

Fmic

Rb25 turbo

Unknown cams (probably tomei poncams)

Pod filter

Cat back exhaust

Thermo fan

Should i get:

Split dump

3" cat

Adjustable cam gears

Bosch fuel pump

Or what bits do you guys recommend?

I would go to Sydney if ican get it done properly in one go. Want to do it ALL for under $4000.

as a guide.

my car has:

pod

turbo back exhaust

fuel pump

15psi on stock turbo

nistune

makes 160rwkw

so with an RB25 tubo you'll get around 10-15% more at the same boost (roughly)

not sure how much difference the cams and cam gears will make.

Definitely finish off the exhaust and do the fuel pump.

I don't think it will need bigger injectors if the turbo you are going to use is an RB25 one.

nistune is up to the task mate.

in some ways, more so than a PFC.

Canberra is only like 3 hours away from sydney

organise a day with a tuner and drive down for it.

      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!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      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.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      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.
