Trans oil cooler off a Stagea
GTSBoy replied to Wazmond's topic in For Sale (Private Car Parts and Accessories)
They make a good PS cooler. That's what I did with the one that came with my (originally auto) Neo engine. Pissed off the simple pipe loop. -
If this was an industrial application (and more so, an equipment/health safety thing) then I'd be mooting a 2 out of 3 voting system. You have 3x sensors, expect and want all 3 of them to agree, but in the event of disagreement of one of them, you use the agreed value of the other 2. And raise a fault. This then places the common failure mode on whatever linkage you have connecting the 3 sensors to the thing that moves, but some common sense can be applied to make that similarly redundant, space being available, of course.

Dunno. Seeing as you can get something essentially the same, brand new, for the same moneys? https://www.supercheapauto.com.au/p/motorkool-external-trans-oil-cooler/SPO442465.html#q=oil%2Bcooler&lang=en_AU&start=49 -
Steps to DIY sanding car back ready for respray....
GTSBoy replied to Boostn247's topic in General Automotive Discussion
Your other option is to buy a spray can of hi-fill and prime it with some pinholes. See if the primer makes them disappear. If it does, then you can leave it with pinholes of that size and they will go away when the painter takes over. -
Depends on what you mean by OK. First up, was this done cold or hot? Are they reasonably consistent? Yes, they are reasonably consistent. Could be better. But unless it has had a build at some point, it is a ~30 year old engine and you'd expect some variation. Some of the difference could also be in user technique Is it good compression? Well....not numerically, no. New they were >160 psi. The one at 140 would be fine, in that context. If they were all ~140, you'd be reasonably happy. But the one that is @120 is twice as far down from the original numbers as the one @ 140. But.. (again)... technique can play a part in the absolute magnitude of these numbers, and the quality/state of repair/accuracy of the pressure gauge is not known. In the context of the above, the compression tester that was used last on my car is regularly compared to a known good pressure gauge. Not calibrated, exactly, but compared to a reference instrument that is not used for any other purpose, so cops no abuse. So we can trust the measurements off that tester. But another tester in the same workshop wasn't being compared against the standard and was reading a good 30ish psi lower. When you're reading 100 psu but the engine is really doing 130, you can make bad decisions.

More likely from tiny bubbles in the filler/putty. Maybe be less aggressive when mixing it. Perhaps invest in a vacuum chamber to pull the air bubbles out?** **I don't know if this is a thing for body filler. I see hardcore epoxy makers degassing their mixed resin on the regular. -
ER34 4Speed Auto 25DE Speed Sensor
GTSBoy replied to CF.Panda's topic in R Series (R30, R31, R32, R33, R34)
IIRC, the speedo on these is fed from the sensor in/on the snout of the diff. -
This is the GTR fuel pump. Yellow shows 12V, orange shows earth. The ECU provides the earth to activate the fuel pump relay. The ECU side of teh relay will pull low when the ECU activates. This is the RB20 fuel pump. Almost the same, but a little simpler. You can see I indicated (above) where the 12V line goes down to the RB20 diagram on the overall diagram, whch shows both RB26 and RB20. This is where I show it coming in on the RB20 diagram below. You can see that the dropping resistor is handled differently. When the fuel pump control is not providing earth to the pump, the pump earths through the dropping resistor and thus runs at lower voltage (some is wasted over the resistor) and runs slower. I showed that "not 12V and not quite earth" portion of the wiring in a paler orange. The rest of the wiring that I did not colour on that little section below the pump would be orange when the fuel pump coontroller is providing earth. This drop is handled inside the fuel pump controller in the GTR. Regardless, you can see where 12V is supposed to be, where earth is supposed to be. The key on prime is via the ECU providing the pump for only a few seconds the switching off. You should be able to see that happen.

Yuh....but weren't all the supertourers, except maybe the Audis, FWD? I don't recall any of the others being AWD. -
Nothing going on there. Stock as.
-
Yeah. I think Moog's GTR was set up with a stock looking layout on the UC10. It looks good. And that you can connect many direct connect signals to it, use it as an input extender for the ECU, etc. Which means for me, it is almost desirable, because I could mostly/sorta use it against a Nistune ECU. But it's a lot of money to drop for an almost/sorta thing. KnowwhatImean?
-
Yeah, The UC10 is the first of these to make it all the way to "acceptable" to look at.
-
We're talking about discrete installations here!
-
Nah, Haltechs are generally able to operate in the engine bay.

Navara? If it's a Bluebird, I might throw up in my mouth a little. -
What heat build up are you asking about? Heat in the wiring providing the power to the Haltech, if remote mounted and power run via the fu(k-da-polees trick wire on the old ECU? Or heat from mounting an S3 inside an original case? I wouldn't run all the power for the Haltech through the trick wire. You just need the activation power. The main power would have to come from an appropriately fat feed. I wouldn't think you could fit the plastic body of a Haltech inside an original ECU case. They're pretty compact these days, but I don't think they're that compact.

GTiR? Noice. -
Which would need the same trick wire routed from the aftermarket ECU to the OEM ECU's plug to make sure the aftermarket ECU won't power up when the OEM ECU is unplugged. Totally doable, just a bit of a pain in the butt.
-
Ozzie cops have known to look for aftermarket ECUs since the 90s. The only ones that could skate buy were bare boards that went into the stock case. If you then went and stuck a Link sticker or something on it, the loss of camouflage was on you. So, no, the new Haltechs won't solve any such problems.

Is there a good place to learn how an engine works online?
GTSBoy replied to RA708's topic in General Automotive Discussion
Twin charging needs the supercharger to be PD. Centrifugal blowers need not apply. -
Ha! I just looked at the photo and saw the pink!

What ECU is it running? Can't do that on stock 33 ECU.

I'm just being rude. The VQ was developed by Nissan Japan, but it comes from the time when Renault were....ruining what Nissan had been before. Just look at a Nissan Tiida, and tell me that you're not looking at a Renault. In fact, just look at a V series Skyline or Z33 etc and tell me that you're not looking at something Frenchified. I just see the VQ an emblematic of that. It is also a nasty sounding thing. I'm really glad I chose to stay RB and not put a VQ30 in when I did my car. As to the RB30 being Aussie.....arguably it's a bit Aussie.
