O2 Sensors Replaced!

Just had my O2 sensors replaced and my R32 GTR runs much better!

During cruise and light throttle the car is more responsive and quieter! I no longer have to down shift to go up small grades and the fuel economy is better. I should have done it sooner!

About a month ago I took my car out to Hills Motorsports to have them run it on the dyno. Before we started, they hooked up the diagnostic tool and found my rear O2 sensor was dead, and the front was not responding very well. At R32 GTR owners know, the Titania sensors are expensive. I shopped around and found Kudos Motorsports had the best price on 2 new sensors. I gave them my info and received the O2 sensors within a few days. I took my car back out to Hills Motorsports and they installed them for me. Driving away from the shop I noticed an immediate improvement in the throttle response during light throttle. A side note, the black on the back of my white car from the exhaust has reduced considerably.

Thanks Hills Motorsports and Kudos Motorsports! I would recommend using both of these businesses!

To talk the the factory ECU you need a CONSULT cable and software for your laptop. It will show what the sensors are displaying and from that you can deduce their condition. I have the PLMS consult cable. It works.

yup, i have the consult cable + software but didnt check o2 sensors prior to swapping to PFC, do u know if PFC picks up faulty sensors at all?

I haven't checked the km's per tank yet... I do know that from Tuesday to Tuesday the petrol gage is down on empty. This week it is on a quarter tank. (Not scientific, I know.) The exhaust sound was louder and you could tell it was rich. Now it runs smoother and the exhaust note is crisper. On any slight uphill I would have to down shift. Now it has some power down low so you can just push on the accelerator a little and it picks up speed. My wife even noticed the difference!

The change is significant if your O2 sensors are bad. Because they are so expensive, have them checked first!

Mark out at Hills Motorsports in Castle Hill is very good.

i've been fairly interested in this thread.

My O2 sensors on my 32 GTR went bust when my turbo blew and obsiously broke the sensor.

since then i got the turbos replaced to new ones, which are the 2860-5's and because the sensor was buggered the car would run like a real pig when they were plugged in. so i unplugged them. then a week later i spun a bearing!

i know bad luck hey!

since that i got a motor rebuild, forgies, new crank, race bearings, thicker head gasket,etc

but didnt replace the O2 sensors, they've only gotten installed today, but for about a month of not having them plugged in on the new motor the car has been runing fine.

getting around 15L/100km which isnt too bad, but that has been conservative driving.

going to pick it up today,

will post again to let you guys know if i notice any difference.

You can even use a O2 Sensor to test it..

On a cruise in 5th gear doing around 60km/h A/F ratio should be near stoich (14.7) as the closed loop circuitry should trim the fuel down so it leans out, if it's running HEAPS rich you know your O2 is dead.

PFC users

ETC, SENSOR SW CHECK

look at 02-1 and 02-2

these are your 02 sensors

they should blip up and down when you tap the throttle

if they are toast they will show 0.00 or hardly move

and the sensor name may become highlighted in black background if its shagged/unplugged

the O2 sensors didnt make much difference to overall power, but it definitely does feel a lot nicer to cruise around.

my fuel ecconomy has improved heaps too, i did a bit of a country drive on the weekend and i've still got a 1/4 left in the tank (yes, i know its a guage reading which isnt accurate at all) but i've done 450+ kms

before i would struggle to get 400kms out of a full tank, i know the country drive would've helped.

the car seems to be a little more responsive at low revs too when its off boost.

just feels and sounds more crisp

i got genuine ones, and i'd say they're well worth the money!

i dont think my mechanic took too long to do it?

he didnt charge me any labour though, because it was supposed to be done with my build but the sensors didnt come in.

i would assume it would be a bit of a pain, just like doing most work in the cramped engine bay of a GTR.

i think you might need a special tool to be able to undo it?

not 100% sure??

they shouldn't alter power output.

there is a special tool, 02 sensor removal tool

its bascially an open ended socket so you can slide it over the sensor and it doesnt clash with the plug

i think its about $30 from repco, without it = dont bother

      Rv37 400r questions

      By elir32 · Posted

      Hey guys. I have a 400R on its way to Australia from Japan currently and have a few questions I’m hoping others may be able to help with.   Wondering if anyone here has had any luck getting the Sat nav unit to work in Australia!? Assuming the Stereo is as simple as a band expanded and tv won’t work?  Seeing as they’re based off a Q50 which is Aus delivered is there any way to link that system to the nav? Nav modules and head unit are different part numbers and appear slightly different at the rear with plug ins etc. can I put my xtrail sd card into the rv37 and will that convert the maps or update to Australian? Has anyone got any advice here?     also has anyone fitted the factory remote start and Security system once it’s landed in Australia? I put an enquirey to Nissan Japan in via a third party, and they suggested it needs a Nissan Japan dealers device to setup and couldn’t guarantee if one here could do it or not. They can supply and I can physically fit it but to setup I would need a dealers device. Any information here would be appreciated also. I’ve seen one here with it fitted already prior to leaving Japan at a dealer/inporter, so clearly passes compliance and works when fitted Japan and doesn’t need changing here.      also, does the tyre inflation sensors work here? Does anything change with them when the vehicle arrives? Where are they actually situated? I’ve read they have batteries and they need to changing at times and seems like resetting involves the nav system?    any help here would be appreciated and any other aust specific information to help would be great. Looking forward to see what the current generation skyline is like and eager to see how many of the gadgets can be utilised here.  Thanks in advance

      Do need to take it with a pinch of salt. One of the adapter failures, they clearly had setup issues with the flywheel.  One of the slipping ones I spoke to and it was pretty clear the throwout was riding, rather than fix, just swapped to a new clutch.    These clutches are being put in anything from 5k offroad 4x4 beaters, GR yaris, 500hp commodores to 1200hp barra monsters. Bound to be some issues in some of them when they are not a simple bolt in affair due to the changes in height.    There is a lot going on in this picture and unless I did the job myself no way to tell what really happened.

      R34 GTT Battery Relocation To Trunk

      By NZ-GTT · Posted

      I did this mod in 2019  You just have to modify the top bracket of the ABS/TC/Fuel Pump Control ECU so it sits more upright and closer to the back seat and run a good quality positive battery lead from the engine bay, the negative lead i just bolted down to the body in the boot.
