Just came across this today via Facebook.

NSW Wakefield 21st - 22nd June

VIC Winton 26th - 27th April

Just came across some video of last years event, looked ok but I think they only had about 7 cars there though.

Anyone interested in participating? Did anyone check it out last year?

went to spectate at the Vic one last year and it was pretty interesting. Got to get pretty close to the cars in the pits and everyone was open for a chat.

Will prob head up again this year to check it out.

I competed in the VIC event last year.

I think I'll pass this year though as it was expensive and I'm a shit driver lol.

What did they charge you?

Did anyone go to Wakefield last year? From the footage I watched the field was pretty barren

I'm pretty sure it was somewhere between $400-$500 for the 2 days.

Richo entered both the Vic and NSW Time Attack. I'm not too sure if anyone else from here entered.

I came 10th out of the top 10 cars as there was only 10 cars left to enter haha.

It's cheap. $300-400 for entry in club. Which is multiples cheaper than WTAC.

Both events were small fields, but it's the first year they have run it.

I'd hope with a bit more promotion this year the field will be larger.

Top 10 shoot-out is a nice change from the norm.

I plan on going to both again.

yeah was the start of the day,

still a little panel work to do, but it won me std 2WD at nats at the end of last year so seems to be back working fine.

Would be at the vic TA this year but expected it to be over easter again, date changed to ANAC and I fly out that weekend so i'm out.

kinda annoying as I picked the holiday dates around it but what you do. had to grab cheap flights whilst I could.

    • 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.
