I am talking about the sensor under the glove box on the transmission tunnel, is there any data on it? Is it 2 axis? How many G does it read up to? What does it output and what voltage input does it have? Anything like that would be nice! Thanks.

I don't have any perfect voltage VS nissan g force data but I do know the nissan g sensors voltage VS my motec actual g sensor data logging.

So motec G force VS Nissan sensor voltage.

It should be fairly accurate I'd think but I don't know the exact g force/voltage the Nissan sensor uses.

Duncan it's all written in a log book from my old GTR that's at the workshop next time your down there.

That's exactly what I have Duncan.

But I don't have motec volts only motec G's

I can look in the motec configuration and find out the voltage/g force figures.

I think it was just a linear ratio from memory.

I was logging the oem sensor both laterally and longitudinally, the motec also did it's own lat & long data logging which is reported in G force not voltage.

Standard 0 to 5 volt output, but I have not found a G force V voltage output curve yet.

Back in the olden days when we wanted to check the calibration of a gee sensor we would tip the thing on its side. By doing so you imitate 1 gee lateral (or longitudinal). 30 degrees = 0.5, 45 = 0.71, 60 = 0.86 gees. If it is linear you could comfortably extrapolate from that up to 5V.

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      lol, yeah, and how gutted I am now I’m back over in Europe (actual Europe) and dealing with the nightmare of U.K.-Continental Europe bureaucracy.   Anyway, arrived in NL early January with the BMW, whilst the Skyline followed suit about a week later. Both cars ended up stuck with their relative importers for about six weeks. Since then, I made a trip to the Nurburgring with a friend and have since ditched the Skyline in the garage. This week, I finally managed to find a suitable shop to do an alignment so hopped on over to Germany to fix the miserable mess the local Netherlands shop conducted; the car was just not aggressive enough in the rear for my driving style - I found myself understeering a fair bit at the ring which was really a first for me with this car. Mis-matched F&R tyres can be held partly responsible - have now moved to F+R NS2Rs. One thing I’ve noticed is the 180kph limiter just does not cut it here. I quickly hit that (for the first time) in Germany on the autobahn. Japanese circuits are small - at least the ones that were near me. I rarely spent much time in 4th. After much deliberation with the HKS SLD, I have ordered Nistune from Matt. Whilst the Skyline has been gathering dust I got to learning the highly neglected BMW I bought in the U.K. was in fact just that, highly neglected. Took the ol’ dog down to Switzerland last weekend with a progressively deteriorating front end. It went from vibration during braking at highway speed on the way down, to vibrating non-stop on the way back. I’ve already fixed numerous engine issues - low oil pressure, f**ked injectors, incorrect coils and plugs, electric water pump. Still to do is a suspension and brake overhaul, rear subframe replacement and likely more ageing engine electrical components. But I must say, I love it. After so long with the Skyline, I really didn’t know cars could be so comfortable.

      Thanks. I adjusted my soft cut to 7600rpm and if I see I'm still making power there, I'll consider readjusting to possibly 7800rpm while on the dyno.

      R34 GTT Wiring Harness Similarities

      Yeah not sure. I sourced another relay no problem, its definitely a relay according to Nissan parts, they used those specific relays on a bunch if cars around that time, but my two options are, find a behind dash wiring loom which is proving difficult, or get the current loom fixed up by the shop when they put my rebuilt engine back in, they are confident in their auto electrical abilities. Thing is my current loom has anti-theft stuff and GPS immobilisers wired into it so easiest option may be to just fix the current one to save ripping apart the immobiliser.

      Asking where to source parts

      Took it apart to get to the bearing found out i was wrong the bearing was pressed on to the diff side and the part i removed only had the bearing side, checked the bearing all looked fine took the shaft end to a shop and they recon it was movement from back and forth that made the marks and not rumbling about, so i just changed the seal and put it all back again.

      Oh dear. That's um. There's like. Um. a lot of bare wires there. Take the whole thing out. Something is very very shorted somewhere. IT IS NOT CAUSED BY THAT "RELAY" (assuming it is a relay).
