Need quick replies please, i'll be doing this today!

I am putting some aftermarket gauges into my car:

Water temp, Oil pressure & Oil temp.

I already know that i can't remove the factory water temp sender near the thermostat housing, as this reports back to the ECU the engine temp. I've already had a friend fabricate an alloy "T" pipe to splice into the top radiator hose, with a fitting welded onto it to take the water temp sender. That's sorted...

But...

Would i be interfering with the ECU or car in any way by removing the stock oil pressure sender (just below the inlet plenum & AAC valve) and stock oil temp sender (behind the oil filter and close to the block) and fitting the senders that were supplied with the gauges?

I was feeling pretty confident that it was ok, before i had a closer look at noticed alot more wiring than i thought there'd be coming from these senders in the wiring loom...

Thanks for the quick replies in advance.

Hmm, 31 views, no replies, thanks guys! :D

At least you can learn from my experiences here:

Well, i've fitted the oil pressure gauge with no problems at all, works well. Much better than the original gauge that has all sorts of problems reading accurately.

Only problem i did come across was that the OE Nissan oil temperature sender is a VERY obscure thread size. A very rare M12x1.25 thread. Realising that a 1/8"NPT threaded sender won't fit, i went to my local Enzed and had no luck with getting an adaptor. Same story at Pirtek, they said only M12x1.5 thread is the most common and doesn't even come close..

Plan B, decided to test the original Nissan sender against the sender supplied with the gauge. This involved getting out my multimeter, digital thermometer and tested the resistance of both senders at different temps in a saucepan of water on the stove!! :bahaha:

No good there, the senders both having completely different ohm ranges.

Plan C, tried looking through VDO's catalogue for an appropriate sender. Turns out that their only sender in the thread that i was after also had the wrong ohms range.

Looks like the oil temperature gauge stays off for the time being until i can figure out a way to get an adaptor fabricated or find a suitable means of fitting this gauge.

Any suggestions?

I hate to bring back my own thread again, but, don't you hate it when you spend the time, money and effort in engineering a one-off part to do something (in this case an adaptor for a water temp sender) and you could have bought something like this:

But my reason for this post, was whether anyone has seen this oil filter sandwich adaptor for sale anywhere here in Australia? It would help me alot if i could get ahold of this product to help hook up my oil temperature gauge (as i discussed above):

The following pic, you can just make out that it's the threads i need, M12x1.25 and 1/8"NPT.

It will need to suit the thread of the oil filter to suit an R32 GTR as well.

Thanks.

I ll bring this thread from dead again, for people's future information. Ring Mark from Motorsport Connections in Seven Hills, they can manufacture an adapter for oil/water temp/pressure.

Addr.: 15/4A Foundry Rd, Seven Hills

tel.: 98387272

I haven't had mine done yet (waiting for oil change). I ll post how I wen when they are done.

      Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.

      Does the scanner do all the CUs in the car, or only the ECU?

      R34 N/a And R34 Turbo (gtt) Transmission.. Uh, Problem.

      @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man

      Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?

      ECU sees many times the speed than speedo does (R34 swap)

      By GTSBoy · Posted

      Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
