Looking at installing 3 gauges, Water temp, Oil Pressure, and Oil temp into my M35




Working off the attached diagram is it possible to simply splice into the Water temp and Oil temp wires to get accurate reading? If not what or where is the best location to install the sensors


Also where is the best location to get the oil pressure signal

even stock ECU has water temp/oil temp signal pin, does your gauge could adjust/alignment against stock sensor (because your gauge/sensor signal voltage may not same as stock sensor signal voltage)? if not, you need to hook your own water temp sensor (which should come with water temp gauge). and buy generic oil temp/pressure sandwich plate adapter for nissan car

i don't think there is oil pressure signal pin on stock ECU due to OBD computer also can't read oil pressure data.

inline water temp sensor could be hooked on radiator inlet hose. (the main water hose beside the radiator cap)

also oil temp/pressure sensor should be hooked on the sandwich plate adapter.

      Is there a shroud around the tailshaft spline into the back of the box? They can rub and make a horrible noise if they are not on straight/damaged. The heat might have caused it to grow too much in one direction and rub.

      Strangely I noticed it either disappear later in the day, or not be present. I definitely noticed when I was crawling around that open wheel thingy entering the pits (that part was audible in car). Driving home and commuting around town for example, I didn't hear it. It's plausible that it was a brake disc or something still slightly in contact. The brakes absolutely felt BAD for the first couple of sessions, huge amounts of shudder and grinding as they got up to temp - And then I actually just forgot about it as the day went on/didn't notice it. The videos were from the morning when this was more present than the afternoon/drive home when it wasn't. I've asked around and got a variety of responses including handbrake shoe contacting hub, CV joints, CB tailshaft bearing as above, and clutch input bearing. I didn't test if it disappeared when clutch was in. I haven't noticed it in any of the other videos nor did I notice it when driving to that extent. More or less hoping the microphone at the rear license plate giving some kind of clue of 'something' but it looks like "spin stuff and see if you can notice it" is the way forward here. I could be smart and use the gopro mic and re-mount it to that location to see if the sound is still present at low speed actually. Sounds like a decent test whenver I have the CBF'ness to drive the car again. Given it's almost 40C for the day of the track day and the next 3 days after, the CBF is high. All I've done since getting home is unpack the car, remove the remnants of the lip and undertray and left it there. I was surprised how well the PMU Club Racers actually worked. The brake performance on the track was absolutely fantastic, best I've ever personally used, no fade whatsoever and the bitiness was almost too good, I was scrubbing more speed off than I needed to, but I also ended up infield when I started trying to scrape off ... less speed.... so...

      R34 GTT idle problem

      Not really, no. Anything you would do is easily reversible.

      I would like more noise related info for my truly uneducated guess  Does it do it at idle or when revving, clutch engaged, and disengaged? Does it only do it when the car is moving? I've heard "similar" noises from a clutch pack that left the chat room, and CV joints that have chewed themselves out But as Matt said, how's the yokes, tailshaft and centre bearing going after their last little issue Fingers crossed it is something simple  Weird noises make me cringe

      One other question, is there a chance that changing the idle speed can lead you down a rabbit hole and is the reason the tuner didn't touch it? Reason I ask is because if that's the reason the tuner avoided it then I probably shouldn't be touching it lol.
