Hey everyone what's up.

I wanted to know if the sensor attached to the Catalitic converter is simply reads the temp of the exhaust or does it work like the O2 sensor in the turbo extension?

Basically I want to know if I can remove that cat sensor all together and not have it screw up any readings going to the ecu or, if I bang a pipe through the cat (so my exhaust is straight through yet still appears legal) and I leave the sensor would that do anything?

I appreciate the help on this one guys, thanks so very much.

Take care.

Cheers

I can confirm it has no input to the ECU and to the best of my knowledge is simply a temperature switch which activates the dash warning light when things get a little hot.

I don't know what the fine in Canada is for gutting or removing a cat for a road registered vehicle but in Australia the fine is substantial ($10,000 for a company I believe) and therefore it would make most people think twice about gutting it or removing it!

Hope this helps,

Cheers

You helped me soooooooo much man, thank you. I was hoping it was something like that.

As for the fine, it's actually not to heavy a fine here and I don't go in to the "problem" spots where cops like to wait *cough*streetraces*cough* so most likely I'll be fine. I do appreciate your warning on it though.

Thanks again brother for everything.

Take care.

Cheers :)

The sensor is nothing but a heat activated switch for the orange "cat light" on the dash. You can indeed cut the entire sensor off (I only have a wire on my car now after i cut mine off) with no ill-effects. Most after market cats do not have a bung for the sensor anyway.

cool and the plug hole for the cat itself?.. i didtn get a cap for it :D tryna find a bolt but cant find the right size (at home that is) haha

Remove the sensor from the cat and go to somewhere like Bunnings where they have those rack of nuts & bolts that you can check the thread size & pitch. To plug up the std sensor hole, just buy a bolt the same thread and length as the sensor and bolt it it in the cat. But be warned - if you just cut off the sensor wire from the car and leave the sensor in, there is a piece that is prone to (loudly) rattle around and give you the sh!ts.

after those few ~38 degreee days of this summer, it seems the sensor itself has shit itself. the cat light in the cluster of my car is randomly flickering on and off.

i'm not thinking the cat has shit itself because i havn't seen any difference in performance. i've gone ahead and cut the sensor wire but the problem still persists.

i don't have any aftermarket managment like the powerfc so what could be the problem causing this?

    • 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.
