I dont think they are...i hardly use mine even though its installed

Someone reputable here once said its not necessary because of something or another, i forgot sorry.

If anything, you can always turbo time ur car yourself

However, the only time i can see where it is necessary is when u really need to get out of the car in a hurry and cannot wait around for the car.

best benefit i get out of having a turbo timer is when i turn my car of and start to walk away and some one says "hey your car is still running"

and then you say "nuh its ok it turns its self off" makes me feel special when i say it :P

that someone reputable was sydneykid

n the basic gist of it was that theyre worthless coz

1. the car sitting still wont cool the oil, moving air cools it. so driving around the block before u turn the car off is more effective

2. they make the car easier to steal

haha 2nd that

It says something about leaving the car to cool down if car has been driven under load or above 100km/h in the car manual, thats the only reason i got one. Tried without but after a few weeks of sitting there waiting for a minute or 2 it gets a bit annoying.

Another thing is i heard turbo timers void your factory warranty, is that true.

'third' that sam. get that 60% of the time at uni and work

Think about it...Nissan have put so much money into R&D into their vehicles...did any of them come with a turbo timer from factory?

That's why Nissan state in the manual to idle car if car has been under load (turbo squirts) for a minute or so. But if you don't do this, well you can just fork out for new NISSAN bits, which they are more than happy to supply you with. :P

Think about it, turbo timers must have a legit purpose. Otherwise there wouldn't be so many reputable brands manufacturing them, and people buying them the world over.

dat is indeed true hahaha had a guy follow me into woodvale shops kept sayin ma car was still runnin left ma jkeys inside ns tuff said it was alright n he goes i'm not liein go have a look ahha had to explain to the guy:P

I have one of the Apexi turbo timers and it displays battery voltage as well as a few other things which I've found useful. You can also turn off the unit which will switch off the car (if the keys aren't in the ignition) without having to wait for the timer to count down if you can't be bothered waiting.

They were first made to prevent older oils from burning up in the oil lines in journal bearing turbos. You don't have to worry about this these days as the semi and full synthetic oils are more resistant to losing their lubricating properties in extreme temperatures.

It's still a good habit to let your car idle for 30 seconds anyway.

With water cooled turbos the turbo never reached the coaking level that does the damage, so I would imagine the are a bit more nessesary after a turbo upgrade when things get hotter!

I have mentioned this elsewhere, but here goes again....

Standard turbos have a pressure fed plain bush bearing. When you stop driving the turbo can take a while to slow down and if you pull into the driveway and cut the ignition, the turbo will continue to spin for a short time, albeit without any oil pressure. If you have been sensible and driven nicely for the last few minutes, and you have a good quality oil in the car, no biggie, the oil present in the turbo will protect the bearing until it stops spinning.

If the oil is old / crappy grade and/or you have been fanging it home (or anywhere) and you shut off straight away either the oil in the bearing will drain away leaving the bearing to cop a hiding as long as the turbine is spinning, or the oil will stay in the bearing and get cooked, stuffing the engine oil AND your turbo!

I gotta say, I am getting pretty sick of hearing about how turbo timers let the turbo "cool down". Nothing will cool down by letting your car continue to idle.

They will, however, extend the life of your turbo when used properly. I just stay right off boost for the last 3-5 minutes of every drive and use a 30 sec timer on the TT. This makes it a lot easier when getting fuel etc as you don't end up standing around waiting for the car to shut off before you can refuel.

its not meant to cool the oil. its so the oil can keep flowing into the turbo to cool it and preserve the it, hence why cop cordias and vls used to blow there motors cuz they chase ppl, switch them off and 'POP'

i reckon there worth it saves hanging around.

im a trimmer and we deal with a few ssangyong turbo diesels which have the merc engine and they have a sticker on the driver door saying to cool the engine at idle before switching off, if the manufacturer reckons so id say there a good thing to have. they wouldnt make turbo timers for the hell of it, also my girls old car the mighty nissan langley had a timer standard which you couldnt 'switch' off

    • 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.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
