Making The R32 Water Temperature Gauge Useful

Before modifying the gauge, while bench testing the sender and dashboard temp gauge, it begins moving from C when the engine temp is at 45 degrees, hits the middle at 60 degrees, stays in the middle until 110 degrees and reaches the H marker at 130 degrees.

This is very stressful, a gauge that reaches the middle at 60 degrees and doesn't move again until after 100 degrees. I am certainly not capable of modifying the gauge and whilst I will install an aftermarket computer at some point, until then, how does everyone else with stock gauges monitor their water temp? I mean, are there any other signs to look for or preventative measures to take? Scary!

/thread means end thread :)

Have a look through the Audio/Alarm section or whatever it's called, a few of us posted up our carpc setups. Basically it's a VoomPCII box from mini-box.com, 7" in dash screen and a consult cable permanently plugged in, Datascan loads on startup so I always have extra gauges and diagnostics.

What is my water temp?

Plug Consult cable in, 80 degrees C, great.

Drive around on various days and under various levels of load.

Rinse and repeat.

85 dollar cable (ECUTalk) free software.

OK I read this and I'd like to say I'm understanding everything but being honest, I'm not!

From where do I get this $85 cable? And then, is it a simple matter of plugging it in to a laptop and running ECUTalk?

Thanks in advance

Edit: OK did a bit of deciphering and I think I've found exactly what you are referring to Sarumatix - thank you! What laptop specs do you run yours on?

Bubba thanks for this link...seems you get the opportunity to make some changes via the plmsdevelopments product rather than just monitoring. Is that correct?

$85 is the right budget for me at the moment (having cleaned myself out for the car). But if this plms thing is hugely beneficial, I'll go with it.

$85 is for the cable

I think a license for Datascan is about $40, whereas ECUTalk is free (not a fan of it).

With Datascan you can make some minor changes for that session (resets when you turn the car off) for diagnostics purposes. I use it to force my water temp to 70deg so that my VCT works (long story).

Thanks for your guidance on this one bubba. I've just ordered the consult cable and will have a go with ECUtalk at first. Cheers!

im using a ECUTalk consult box thingo, so i can see a digital readout, but still that's a pretty awesome idea

its always bothered me that i can see the temp change 15 degrees without the needle moving, didnt realise there was a normalisation circuit

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?

      M35 Brake caliper replacement

      By Duncan · Posted

      You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
