Oil Pressure Sensor Upgrade?

Does anyone know the signal range for an RB26 oil pressure sensor? 0-5V?

I want to switch the stock oil pressure sensor with something more accurate and reliable that sends the same signal voltage. i replaced my stock sensor with a genuine Nissan sensor, but i think my Nitto oil pump killed it already. I eventually want to put a Haltech in my BNR32. i can buy a haltech sensor and run the stock pressure sensor for the gauge but i would like to find a same voltage range sensor that would give an accurate reading for both the haltech and the factory gauge.

The standard sensor is 0-5v but I've never seen the calibration for it to confirm if its the same as the generic one Haltech uses....most likely it is the same or sufficiently similar (considering you don't exactly get an exact reading from the stock gauge.....)

In any case your oil pump doesn't damage your pressure sender.....time and 000s of klm of vibration do. They are a reasonably common failure, just replace the standard one....in your case I'd go second hand if you intend to go aftermarket ECU soon anyway

So i wired the AUX 0-5v output from my AEM 0-150 oil pressure gauge to the factory oil pressure pigtail. The gauge didnt show any signs of life but now my climate control display is looking pretty screwed. Not sure if its coincidence or not.

First thing i did when i bought the car was replace the bad oil pressure sensor. Oil pressure was strong after that. But after i rebuilt the engine that new sensor worked fine for a while then quickly started showing low or no pressure. Worried, i replaced it with the AEM and oil pressure was 90+psi cold at idle. I dont want aftermarket gauges in the car so i was hoping for an alternative to the stock sensor that would allow the stock gauge to function accurately.

Sorry am I missing something here or are u trying to read pressure off your temp gauge. I am a bit confused.

I would like to read oil pressure from the stock gauge but looking for a more accurate sensor. After a couple days the heater controls started working normal again.

Correct me if I am wrong but I thought the stock oil pressure SWITCH is just a single wire 5v switch. I don't know what they are calibrated to read between in terms if their range 0-100psi ? 0-150 psi ?

If you're installing a 3 pin pressure SENSOR then the ecu needs to be calibrated to read the range correctly otherwise it won't know what to display. If you're still running a stock ECU then how are you going to calibrate the sensor correctly?

      Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.

      So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around with a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.

      Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.

      It ended up being that orientation of the float hub in relation to the clutch disk, when I installed it, I heard a loud click and being stupid, I decided to not take it a part and check it. The hub didn't properly align with the clutch disk and was causing the issue. Definitely an odd one! Dahtone Racing was able to fix me right up, stand up blokes!

      Right, but I'm saying on the stock ECU measured airmass from the MAF is no higher than stock. So it's accounting for the higher flow rate iso-manifold pressure. You just have to keep turning down the boost until you're within the stock tune's load scale. If you run off the end there's no telling what will happen. This does mean there's zero benefit to the turbos you're running vs stock, if anything it's just a straight downgrade because the transient response is worse, you don't even get the ECU's boost solenoid helping to pull the wastegate closed during initial spool, and peak power is only whatever the factory map can give you before you hit the R&R corner. On a -9 I would bet that you would have to change out the wastegate spring once you have a real ECU and you're tuning it for real. I'm not saying this is a remotely ideal state of affairs, it's just a way to keep it driveable until you can get a proper tune done.
