Hi all i got my r32 gtr and it is near impossible to keep the front windscreen fog free. The demister works quiet well but the fogging is on the outside of the window and i do beleive it is the heat of the motor fogging up the screen is there a way to adjust the bonet to help reduce this or a automotive product to stop this. It is quiet annoying.

G`day Scott,ANTI FOG made be RAIN X ,is a great Product so try see ifthat will sort your WORRIES OUT ,also what do you clear inside with look at what may as cause your worries,,GOOD LUCK,

cheer`s Chuckie.

cheers i knew about rain x just couldnt remeber the name of it lol and i dont use any products on the inside i only use a shamy and a clean lint free rag works a treat

do u wipe rain x on the inside of the glass or outside i know this may sound retarded LOL :)
RAIN X only on OUTSIDE ,ANTI FOG for INSIDE ,so good luck cheer`s Chuckie.

is it only fogging up if you have the demister on? if so, it may be that the aircon is the cause of the issue. if i drive for too long with the demister on on a cool night it actually starts to ice up the windscreen. solution is to turn the heater on and defrost it.

How would heat from the engine cause water vapour to condense on the windscreen? Surely it would help the condensed water to evaporate.

Keep the glass clean, then the water vapour has nothing to condense around.

on reason why it could be the heat from the engine is if the engine has a coolant leak and the heat is causing the coolant to boil and the resulting steam is fogging up wht windscreen. in which case, you might want to check the coolant level before you drive the car next to make sure that isn't happening

in some cases the heater-core (that has coolant running through it) (located behind the dash) can have a slow leak which puts too much moisture in the cabin

is there any other stuff in the cabin that would add moisture?

p.s. my car fogs up heaps, even this morning.. and i dont have any aircon

Edited by gfunkk

did it fog up the inside or outside?

also not having aircon can make the inside fog up in the wet, etc, especially if you have just had to run through rain to get into the car. the aircon pumps out dry air and so the moisture gets dispersed a bit as it mixes with the dry air. no aircon just pumps around moist air so the moisture just builds up

    • 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.
