Thinking About Swapping All Sensors On My R32 ?

I had tuning issue last year.. so many that I was frustrating when driving my GTR... so we finally discovered my TPS was faulty.

-bought a new one.
- My tuner, mechanic and friends told me that a new ECU would probably make the car run smoother overall. so I bought a Haltech plug-in
- I then decided to buy a Raw brokeage CAS just in case mine was having some fluctuation etc.
- Swapping the MAF to MAP so I bought the IAT and MAP 3bar sensor from Haltech
- I have a grounding kit
- Got myself a HPI6 unsure if it's worth installing it.. but got myself new OEM coilpack and harness

So I'm wondering, is it worth swapping the 2 knock sensor to replace the 24yr old one !? Same goes for 02, are they worth it ? is there other sensors that could be wise to swap since they are all 24yr old..

I just wish my car will run smoother in 2014!! arrgghh

Don't know about the Haltech but my Link computer doesn't use the O2 sensor. If your Haltech does then by all means get a new one (or two) if its still using the original ones.

i contacted haltech and their answer was that it would be better to swap the narrowband to wideband.

How about knock, is there a better replacement than oem ?

This is the knock sensor that Link lists - it should work with the Haltech although I am not familiar with the Haltech and don't know if it reacts automatically to the knock info or whether it is just used by the tuner.

Did you read the article I linked? The Platinum Pro ECU allows you to turn the factory sensors off so that you do not have any sensor codes. Narrowband sensors cannot read like a wideband sensor, they only show rich or lean in relationship to stoich for gasoline. You need a wideband sensor before the catalytic converter to be able to properly tune your vehicle.

Not quite sure what you're getting at here. I don't see any link in your posts. Yes I know the difference between narrowband and wideband sensors. I thought we had moved on to knock sensors.

sorry. i should've introduced my post but this answer was from hatlech tech just in case someone in the futur search for information.. it will be there :)

2x new knock sensors

haltech 02 wideband can kit

new ignitor and coil pack loom

I'd also go with a haltech coolant temp sensor

smoother? check all your intake, pipes, hoses, gaskets, tb shaft seals, idle solenoid etc..

then lots and lots of non-power tuning....

thank you for your answer. this confirm what haltech told me.. I need to buy the wideband kit now! it appears its much easier to tuen wideband than narrowband.

Its not just easier with a wideband, you can't tune with a narrow band.

I need your input again skylines expert!! :D

I need to delete the oem narrowband and fit the haltech wideband system.

Option 1: remove manifold and everything else to swap the narrowband to wideband ( labour approx. 300$) If I need to swap them over later on.. I still have to deal with the removal of everything again.

Do you think I could simply weld 2 bung to my front pipe so it would be easier to swap if needs to be ? Actually it have to be removed because it have to be calibrated air free.

Thanks !!

Why do you need to remove the manifold to remove the O2 sensor? Is it very hard to reach? Normally you would just unscrew the old sensor and throw it away (unless you have recently renewed it) and then screw in the new wideband sensor. There should be no reason to revert to the old sensor as the wideband sensor generally has the ability to also provide a narrowband signal if you need it for some reason. But if you have to remove the manifold then put the new bung in a place where it can be reached without having to remove the manifold and just plug up the old bung.

I could be wrong, i thought the oem bung was on the dump pipe where acces is not possible under the car so the needs to undo a couple parts on top is necessary.

Get a bung welded in. Easiest/cheapest/recommended/ most normal option for fitting a wideband. Too close to the manifold they get too hot, some people are ok with them mounted in the factory location, but pretty much every manufacturer I have seen doesn't recommend that location.

Would you guys keep using my profecb or use haltech own boost controller option ? Since I already have the greddy hooked and work great i wanted to keep it but just curious if maybe I'm missing an advantage of letting haltech control my Boost too.

Don't knoiw how your Greddy works but I use the Link plus a Mac valve to control boost. It uses the air temp sensor and map sensor and is probably much more programmable than a stand alone boost controller. I would think your Haltech would do the same. You just have to buy a Mac Valve and then you can sell your boost controller so $$ in your pocket.

      LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

      Jacks that fit under GTR lips that can reach the subframe?

      By GTSBoy · Posted

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
