Just a quick one....

I have replaced the exhaust, cat, intercooler and pods on my 33 GTR. the Power FC has recoreded some higher then normal knock readings also

Should i get a tune asap? or would it be ok to drive for awhile? As i cant get in for a bit to the tuner i want?

I'd be surprised if those mods were causing higher knock, unless your previous tune was pretty close to the edge. But it's definitely better to be safe than sorry, if it were my car I would assume it is knocking and not drive it hard until you can get a tune. You can still drive it, just don't go loading it up everywhere.

You would think a free'r flowing exhaust and front mount would reduce knock??

If you can't get a tune for a while drive it normally ie without thrashing it until you can get it checked

Out of curiosity what knock readings you getting now?

or just blanket some more fuel on the map, there's a chance with new pods the AFM is reading slightly different causing a lean miture, you don't have a wideband O2 by any chance?

AFMs are sensitive little shits.

Well you didn't need to swap the parts over, it was a choice. Just like it's your choice to go and get a tune sooner rather than later.

So keep babying it and say a little prayer each night.

^^^ haha.. :yes:

maybe this new exhaust system doesnt flow as good as the last and its causing restriction which =knock with the same timing etc.. :whistling:

    • 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.
    • Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
