i'm no guru, mate. i would like some one to provide the air flow curve or moded values for the vq curve, and i will buy 2 of them asap.

if you can provide these curves then i think that all your R35 AFM's will go like crazy. The jap links are in Japanese and that helps no one mate.

I do believe that the what you describe will come to be more and more main stream, and that you are on to something good, but i have to time the way i jump on this idea.

thanks again why are you selling yours

the Japanese link can be converted but shows the important part in english i.e FC = power fc and r35 afm

I bought a few to test out when I saw they were doing it in japan my last trip now I have one running on my s14 Im selling the extra's

nisstune can supply the vq map to any auth dealer and have already with there latest upgrade

if your tuners a nisstune dealer as well (as alot are these days) Ive sure they'll help them convert it over to the fc

just ask your tuner'

if you tune yourself search vq r35 and images in google Ive come across a few things that look like vq maps to me but Im not 100% not being a tuner myself

came across this article in a older drift mag

shows guys running power fc with 100mm pipe making 450ps

with the 35 afm reading airflow ok for tuning other guys running 80mm

for there power levels

sorry pics aren't very clear camera's playing up

Well this is whats happening. after revving the engine it wants to stall but don't after it comes to idle. I can see it push out black smoke at close to idle. I feel as if it has to do with the bigger turbo still spinning to fast and pulling air through the AFM's. i have the BOV's vented back in through a Greddy Y-pipe so I'm thinking that the location of the returning air is fine because the Y-pipe has a spot for the returning air. I notice that i can drive through this phenomenon if i keep in mind that i have to let the turbo slow down by clutching in at the last moment. Only then does it not stall, or come close to it.

any help would be appreciated

Thanks Mate.

I had the exact same problem for a couple of years and it drove me insane. I had 2 Blitz BOV's venting to atmosphere and a power FC on my GTR.

I changed to the stock BOV's and stock intercooler piping and reconditioned the idle control valve and the car now comes of boost without dropping below 1000rpm and idles perfectly!

      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.
