hey Guys,

I have started cleaning up the wiring on my car and found the knock sensors weren't even hooked up. Now my car runs a Haltech ecu but i still would of thought it would need these to run, can anyone shed some light on this for me (esp where the sensor wire plud is suppose to connect to)

Look down the back of the engine on the drivers side close to the inlet runners.

And on further searching have found that they do not incorporate closed loop knock sensor control.

Future reference....www.google.com.au

Type - Does Haltech use knock sensors

Google is your friend.

Well maybe....

In the end if the tune is safe, you use good fuel all the time, your injectors are clean, your fuel pump is in good condition etc etc.

With skylines a standard ECU is the only computer that uses the knock sensor as input, it moves to a "safe" map when it detects knock.

PFC comes up with a knock "number" based on the sensor but does not use it in the tune. If it is knocking its up to the driver to back off.

AFAIK no other aftermarket computer uses an rb knock sensor

The Link ECU has a system where if the knock is too high, it will reduce the boost level until the knock is reduced. The Link ECU uses the factory boost controller to control boost up to 14psi.. COuld be more, not sure though.

bit of a question on this one...

assuming i'm using a stock ECU, is there any way to monitor knock?

I've got one of the Nissan Datascan units that Impakt (off these forums) makes that gives a readout of all the ECU parameters... the only one that it doesn't give that could be helpful is the knock readout....

any ideas?

ok I have found turboXS make a knock light and shift light all in one ($180 approx) (look in the current autosalon mag) Unfortunatly every supplier for turboxs I have tried haven't even heard about them let alone stock them

      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.
