My Car was originally a N/A Series 2 R34 (auto)

I was curious if anyone knew what temperature the warning lights for AT Oil Temp, and Engine Oil Temp actually illuminate at? I can't seem to find this information anywhere, even in the workshop manual. The workshop manual does mention the light comes on but only when the sensor detects variables which are everything except actual temperature.

Just curious before I bought gauges (which I will anyway) to see whether these can be relied on as actual warning lights, in a "It is time to immediately back off" kind of warning.

My google fu is clearly feeble.

I understand this, my car actually has it labelled as "AT Oil Temp" (thats the actual text of the lamp that lights up)

I also have an oil idiot light, as well as an oil pressure guage in the standard cluster with a LED on it from factory.. which lights up when oil pressure = 0 or extremly low - But there's also another one with the typical oil icon which doesnt appear when the pressure LED is on, but does appear when you turn the car on prior to starting it, etc.

Was mainly looking at the AT Oil Temp one if anyone knew, as the oil pressure gauge does a laymans job of telling me if the oil is hot or not just by going on how much pressure is there when it warms up... (20w-60 oil) and well water temp has the little needle which doesn't move until something is seriously wrong. Not overly worried about oil overheating as everything I've read seems to indicate oil and coolant tend to go into the 'too high' region at the same time.

I'd be getting proper gauges before any kind of track day, but curious through spirited driving through the hills what the AT oil temp actually is, because cooking a laptop to the transmission ECU to read it is rather cumbersome, and the AT Temp is apparently the first thing to get worried about. Was wondering mainly if the light comes on at 80C where it isn't 'that bad' a problem or whether it comes on at 150C or something in which case it's too late.

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
