Apps / Re: Tyre Pressure Engineer

Just to clarify, of the two numbers one is lap average, the other last corner?
I'm getting around 100 for the top number and around 0 for the lower but not understanding why they are so different??
(I'm in the ACL Mclaren M8C)
Yep, one's lap average and one's last corner only. Is the Average 0? Maybe it's possible to get 100 for one corner, but average of 0 over the whole lap (if some corners are negative)? Is it always 0, or does it change?

I have updated the app in the first post to add information about lateral weight transfer.

Here's the theory, as I understand it.
As you corner, there is lateral weight transfer, so the tyres get loaded and unloaded. There's not a great deal you can do about the weight transfer - it's going to happen. What is important for the handling and balance of the car is the amount of weight transfer at the front and the rear, or in other words, the roll stiffness. The larger the lateral weight transfer at either end of the car, the more total grip that end loses.  A more balanced car will have a similar amount of weight transfer front and rear - you want both the front and the rear to lose around about the same amount of grip to maintain a balance.

So the app shows two numbers, both related to how much more lateral weight transfer there is at the front compared to the rear. The bigger the number, the more weight transfer is happening at the front compared to the rear. If the number is negative, you are getting more lateral weight transfer at the rear. The "Corner" figure shows this for the last corner, and the "Avg" figure shows this averaged over the whole lap.

A stiffer end has more lateral weight transfer. So if you want to get a positive number that the app displays closer to 0, soften the front or stiffen the rear. If you want to get a negative number that the app displays closer to 0, stiffen the front or soften the rear.

A good car to experiment with is the Ferrari 599XX Evo, as that has a big range of ARB adjustment.

You need to enable Dev_Apps.
This is located in your main install: (steam crap)/assettocorsa/system/cfg/assetto_corsa.ini
Once you do this, you'll have access to the Wings app, which shows total d/f for each element, d/f & drag coefficients as well as CoP % (front) (I call this the wind tunnel).
You'll also have access to the Car Engineer app, which gives damper ratios as well as suspension frequencies (shaker rig).
I use Car Physics app to get the weight distribution which locates the CoP (just rearwards of this point).

Enjoy the world of numbers. 8)

I simple to understand app that gave these numbers in a way dummies like me could understand would be cool
Some, or most, of these measurements aren't exposed to public apps, unfortunately.

Did some aero mapping in the E21 and managed to get 40% front CoP, even without a front wing. 8)
And that allowed me to get the spring frequencies back to a more traditional delta. ;D
Setup posted on sTracker. ;)
But did it make you faster? :)

I'll take a mtx_103c_r2 thanks Phil.

@Wally, I was watching you close in on me in my mirrors and was trying not to give any easy drafting pass! I had touched the wall in R1 so knew how cafeful you have to be. Sorry/Glad our little excurtion to the top of the track had the desired result. ::)
I wondered if that move up to the wall was deliberate. If so, it was a good move.

Hi Wally,
No mention that I was only on the ripple strip because Jeremy hit me up the arse in the middle of the previous turn which let Kcender breeze through into 2nd place???
Sorry, you're right. I missed the earlier hit of Jeremy into your rear which let Kcender past. So that's a penalty to Jeremy for that impact.

Aug 21: Queensland Raceway [DOWNLOAD]

17 lap sprints.

NOTE: If you already have this track, there has been a version 1.0 update on Aug 13, so please redownload it.
Weather forecast: 23, 29 and 29 degrees and sunny.

My 1st two races were great - lots of close racing, made no mistakes and dodged other people's accidents. I couldn't quite get the draught enough to pull of a pass into the chicane, and turn 1 was often nice and hectic with people with the draught having all sorts of different entry speeds.
But race 3 was screwed. I was starting 5th courtesy of a good finish in race 2, and was hopeful for a good points haul. But I spun all by myself exiting the road section onto the oval on lap 1, and did a big, slow loop-the-loop out in the grass that left me last. The game also put me a lap down at that point (which I have adjusted in the points only for race 3). Then a few laps later while trying to make up some ground, I was draughting AbleArcher when I got too close to the wall on the banked section and hit it, which damaged my aero, broke my suspension and ruined my top speed. That was race over - I just circulated to the finish at that point.

Results are up in the first post.

RussG, this is how the server reported the finish to race 1, with you in 3rd 0.004 secs in front of Matthew.

2) Jeremy BEST: 1:47:117 TOTAL: 19:58:198 Laps:11 SesID:2 HasFinished:true

Server's up.

Fastest time on the practice server was set by RussG, with a 01:46.681.

Australian Assetto Corsa League, Tuesday nights / Re: Season 23 Sign Up
« on: August 13, 2018, 12:02:16 PM »
Hi everyone, new here. Is it possible to sign up this late in the season or is it best to wait until next season?
Hi Mac, welcome. No worries, that's fine. I'll shoot you a PM with some details.

ahhhhh... crap, that many already  :o

I guess I will have to sheepishly accept my first win as you all pull out of the way on the last lap.

Thanks in advance!
I would let you, but it's too close in the standings. There's only 2 points between ab156, Freezer, Shane and myself, 5th to 8th.

yeah i dont see them either, only way i know is by watching the chat window when i think i cut and keeping count lol
If the app is visible, it should always show something like "Warnings: 2/3", and it pops up a little flag too when you get a cut. It pays to have the app visible.

Results are up.
Hey Wally, just noticed that on each results page the result in the table for me is different to the chart.
The chart from my memory is accurate.  I also have my position in red in each result in the table for some reason.
Not sure which has been factored into my points for the round!
The charts show your true position, while the results show your position adjusted for any time penalties (that's what the red position indicates). You had about 4 cuts in each race. I'm guessing you didn't have PLP visible so didn't see the warnings.
