Each tyre type has an ideal pressure for optimum grip.
This app keeps an average of your tyre pressures over the last lap, and lets you see how different the average pressure of each wheel is from the ideal pressure.
You can set the ideal pressure for each wheel (it defaults to the current pressure when you start). The app shows the current pressure, the average pressure over the last lap, and how much you have to increase or decrease the pressure in the pits to meet your ideal pressure.
The current pressures are colour coded for temperature. Blue -> green means too cold (green is closer to optimal). White means in optimal temp range. Yellow -> Red means too hot.
Unzip into steamapps\common\assettocorsa\apps\python.

The optimum psi for the M4, according to the tyres info, is 36 all round. Optimum for grip, that is. It seems that in a lot of cars, you go faster if you put the tyre pressure pretty high, so I don't know how optimal that pressure really is.
For the Lotus V6 cup, it's 34 front, 35 rear.
Formula Abarth, 24 all round.
SCG 003, 33 all round.
-
Wouldn't the temperature also factor into it, so lowering the pressure below optimum might yield a higher temp and more grip that way vs. Optimum pressures?
Sounds like a great app though.
-
For the M4, peak grip is 75 to 95 degrees.
I don't know which is more important for grip though - temp or pressure, or how they combine.
-
I would think temperature if it's the difference between being in the right temp window vs being 10 degrees too cold.
However many of the road cars don't heat up the tyres so they are are cold natter what, in which case I think pressure would be the thing to focus on.
I'm pretty sure Kunos are working on the cold tyres thing though.
-
I updated the app in the link in the first post.
Understeer/OversteerI've added a measure of your average understeer or oversteer. The app displays a number for your average understeer or oversteer for the last lap, calculated from front and rear slip angles. The bigger the number, the more you are understeering or oversteering. The app also shows an instantaneous meter of your current understeer (green bar) or oversteer (red bar). You can use this to see if a setup change has made your car more understeery or oversteery.
When your pit limiter is on, the averages for the current lap are reset. This is handy if you've made a setup change and want to start again with your averages. Otherwise, you can just do more than one lap with your new setup - the app only keeps an average for your last lap.Understeer/OversteerI've added a measure of your average understeer or oversteer.

Sounds great. Did I just read the same thing 3 times? Is this some sort of test?

No, your vision must be blurred.

Do you know what the ideal tyre pressure is for the Lotus V6 Cup Semi-slicks?

Thanks.
How do you see the optimum pressures for a random car though? Or is it all built into the app for Kunos cars?
-

You have to decrypt the acd files for each car. If I can automate it, I'll produce a shared Google doc. There's optimal tyre pressures for every car/tyre combo.
-
Thanks for the app, I find it handy
-
Sounds interesting, I really think optimum temps and pressures should be shown somewhere in game not needing to decrypt acd files. The oversteer and understeer thing not sure if id need to know that, thats something I can feel easy enough but may be of use to some.
PS the Wally bot seems broken it keeps repeating itself.

Wally is there any chance that you could put together a table of each car and the optimum tyre pressure?

Yeah, I'll work on it.
-
That would be awesome. I guess it'll take a lot of work though with probably over a couple of hundred different car and tyre combinations.

Nice. I was also thinking that you could so a similar thing for tyre camber as what you've done for pressure. If you look at the average temp across the tyre - inside | middle | outside, ideally the temps should be fairly even if your camber levels are right.
There may be too much variation though between different types of corners and straights?

Here are the ideal pressures for grip of each car:

That's amazing. Awesome work Wally!
This info will help a lot.
-
Cool. I'm not sure what to make of the camber though. I think that's a little more complicated than just measuring IMO temp spreads. AC doesn't output tyre temps to telemetry channels, and I don't think you can read surface temperatures from an app (only core temperatures). Otherwise, you could get a good indication of optimum pressures (middle temp neither too hot nor too cold), and good cambers (by averaging out surface temp spreads, taking readings only while cornering).
-
Ah but that'd completely take the magick out of setting the car up! ;)
-
Ah but that'd completely take the magick out of setting the car up! ;)
That's the plan! Remove some of the black magic. Problem is, approaches like these assume that just because an even tyre temp spread is a good thing in real life, that it makes any difference in AC. It might be completely irrelevant to car behaviour in AC.
-
Also, for GT3 tyres, the optimum temps are:
Soft: 80 - 95
Medium: 75 - 90
Hard: 75 - 100
-
I havent tried this app yet but would be great if it came up and showed the ideal temps and pressures for the current car and tyres in use. I mean not all of us will hack into the physics files to find this data but really this is the sort of info that should be shown inside the pit or at least as it loads.
I mostly use temps and pressures from dashmeter pro and can also look back at the telemetry feature in it to shows temps and pressures after a run. For that I dont really need this app going by what it does but getting easy access to ideal temps and pressures would make the app very usefull for me.
Regarding cambers this would mostly be used to dial in the ideal temp range at the ideal pressure. Raise or lower cambers to try and get temps and pressures both at the ideal range. In some cases you wont ever get both in the optimum window and in that case you would try mostly for temps but if your still way out on the temps you will just work on pressure.
I try and balance hot pressure around the car more then temps though, you will never get even temps all the way around but having tyres under pressure or way over at one corner will effect laptimes even more.
-
Ideal pressures for each car (excluding mods).
Put the attached file into assettocorsa\apps\python\TyrePressureEngineer.
-
I wonder with the camber thing whether, instead of using temps as suggested, there is an optimum grip measurement output from AC?
Actually that would be handy for all changes really, if you could somehow measure and graph grip at corner entry, exit and braking etc. That would allow you to see the difference changes to a heap of different settings makes. But I am just dreaming.

Probably the best thing that apps actually have access to is lat and long G forces. The more grip, the more G's you can pull.

A good tip if you guys dont want the game to change these is make it read only, otherwise it will always adjust this to your starting pressures in a new session.

No, don't do that, because the app deliberately writes to the ini file if you change the ideal pressure for a car/tyre to your own preference. The first full ini file I put up was bugged, so it gave the appearance of resetting the pressures to the starting pressures, but now it doesn't.
-
Ok maybe thats what gave me some fps issues yesterday then. :-[
Thanks Wally I will update the app with the new one.
-
Updated the attached zip file in the first post. It now allows for higher pressures up to 55 psi (for some of the older vintage tyres).
-
I've updated the ideal pressures file in the first post with the new 1.5 cars.
-
So far on 3 tracks (Spa/AudiGT3, Brands/EscortRS, and Barbagello/GT85) it has improved my times.
And this was after I already improved my PB's with 1.5 release
Thanks for this Wally ;D
-
Thanks Wally, I never realized that this was another of your awesome Apps.
I hope I wasn't out of line with anything I said the other night when talking about tire pressures for the Caterham. :-[

Ok, thanks
I correct myself: it looks like there is a bunch of new tyres after 1.5, and some of the old tyres must have changed names. So basically the app suggests 24psi for all of them (BMW235i racing, F40 S3 are two examples I have noticed).
For the rest, the app is really amazing. I used to find it hard to cope with radical changes in temperatures, and some cars were really strange on default setup. Now I just follow your (the app's) suggestion and immediately can enjoy any new car and conditions. Thank you so much. :)

If I'm 4-5psi off I can gain around a sec/lap just by rectifying it. ;)
-
Definitely one of the "must have" apps. I've found even 1 or 2 psi makes a fair difference.
-
I'm glad it's useful. I use it all the time too.
-
I uploaded a new version in the first post that updates the ideal pressures when you change tyre compounds.
-
Updated with Triple pack cars.

Thanks Wally, I will be interested to see how far off my guesses were from some trial and error testing the old school way.
-
thanks again Wally.

I added a timer to this app that shows you how long you're in pits for (in pit lane + pit stop duration).
-
For Phil to try:
-
Update with Porsche pack #2 cars.
-
Updated for AC 1.11 and Porsche Pack 3.
-
Won't be able to enjoy for another week at least, but---in the meantime---thank you! :)
-
It's worth noting that KS changed the optimal pressures for quite a few cars - GT3s I think. They lowered them from around 33 to 26.

The download on the first post is the one. This is all automated - I just press a button and it spits out the file.

Thanks Wally, tried the Kunos adaption but just not as good ;D

I updated the app to show how ideal your current tyre temps are (download in the 1st post).
The current pressures are colour coded for temperature. Blue -> green means too cold (green is closer to optimal). White means in optimal temp range. Yellow -> Red means too hot.
-
Updated with 1.13 cars.
-
Thanks again Wally
-
Bacchulum,
After you've tried the app, have a look at My Documents/Assetto Corsa/logs/py_log.txt. Attach it here - that's where you can see app errors.
-
Here's my log from race 2, I guess.
-
Here's my log from race 2, I guess.
No errors in there. App errors are normally what stops the icon from appearing. Maybe try again. Make sure the app is enabled in the launcher, try to go on track and then send both py_log.txt and log.txt.
-
My tyre app sometimes is not in the game or in the list of app in game but is ticked in the apps in the menu, I have had to delete and replace it to make it appear again
-
I've updated the app attached to the first post:
Temperature Delta
The app also shows the delta in the tyre temperatures, averaged over the last lap. It shows the difference in temperatures left to right (negative means left side is hotter; positive means right side is hotter), for both front and rear, and also shows the delta between the average front temperatures and rear temperatures (negative means the front is hotter; positive means the rear is hotter).
This can be used as an input to tuning the balance of the car. For example, as a rough guideline, hotter tyres at the front may indicate understeer, while hotter tyres at the rear may indicate oversteer.
-
Sounds great. Did I just read the same thing 3 times? Is this some sort of test?

I think maybe this version is broken, just tried with the 919 and ideal pressures changed when I changed pressures in the pits. It did show correct pressures at first I think 35 all round or similar but then after making changes it showed 37 35 36 34 in the ideal pressures window. I did remove the old version and try again and it did the same thing.
It only does this during the session, once it ticks over to a new session the optimum pressures are back to what they showed before changing the pressures.
-
Hmmm OK, I'll have to check that.
-
I know it does that with mods, but official content? :o :-\

Hey Wally
When I installed the DRS app the first time Tyre Pressure Engineer stopped showing on the right hand menu. It was still listing in the game options and checked. I reinstalled it and it came back, but I've just logged in again and it's again now showing on the right hand side. Is there any kind of conflict between the two apps. I'm just about to try and reinstall it again.
Cheers

There shouldn't be. You're not just using different app desktop presets (1 to 4) are you? That can be confusing where the same app can have different positions within different presets.

No it's not that, I have it set to 1. I reinstalled TPE and both apps were working together again. It had never happened before but has happened twice since installing the DRS app.

Thanks Wally, I have two shiny new PC's with clean AC installs so I will grab the latest and install tonight. Did some laps around Nords last night with tourist layout, slipped all over the place in the Porsche GT4 clubby. So, so rusty

Hey Wally, how do you find the optimum pressure for mod cars? ???
I find myself driving more and more mod cars and have no idea what the tyres should be at. :-\

Content Manager

Decrypts data.acd and writes the results to the .ini files of 'Race essentials' and 'Sidekick', but not to Wally's App as yet.

Is the ideal tyre pressure dynamic in some way? When I first joined nurb practice server in the porsche lmp1 I did a few laps and adjusted pressures as recommended, left, upon returning I loaded my saved set up and now the app recommends more pressure. I didn't look at the values to begin with but to add a few psi the first time and then it recommend I add a few more psi next time seems a little odd...unless it's a time of day thing? Also noticed something similar at spa and didn't think much of it, but my race times were quite slow and the car didn't feel right (probably just fuel load)
-
I don't think they're dynamic in any way. You can set up the server to start with different temperatures, but I don't think the practice server is set up that way. The wind has some variation in it though, so that might affect top speed etc, depending on its direction.
-
I even think different grip levels affect the ideal pressure.
More grip generates less heat, therefore a lower start pressure (and vice versa).

So the track quality is dynamic?
-
On race night it is but I just remembered on the practice server it's a constant 100%. :-\
-
Though in the past Wally has from time to time changes the weather on the practise server to match real world weather. That kind of change will mean the start pressures would be different.
-
True Joe, but currently the practice weather is the race weather. The only variability is a slight change in wind speed and direction (a bit of randomness on each session change).

I've gotta keep an eye on it, I think my ideal pressure is changing, also some cars at some tracks will have all four tyres at different "ideal" pressures. Maybe it's normal and I never noticed it before
-
.....also some cars at some tracks will have all four tyres at different "ideal" pressures. Maybe it's normal and I never noticed it before
I only see that behaviour on mods that have no entry in the .ini
The app seems to pick random numbers if there's no entry.
Fronts can be different to rears but if there's an entry, left/right will be the same.

Ok, I think I first picked up on it in the mod GTR and thought it was happening in the Porsche lmp1. Still I'm not 100% sure though I'll keep an eye on it. Does anyone know the ideal pressures for those cars?

If the mod is unknown to the app, it just picks the starting (cold) pressures as a baseline.
Does anyone know the ideal pressures for those cars?
For the LMP1's, it's 35 all round.

Didn't see your message until you left, thank you very much. For some reason the app had something like 42 43 39 39 in my lmp. The vintage tyres were about 38 on the Escort?

If you manually adjust the tyre pressures shown in the app with the + and - buttons, it saves those values as your new "ideal" pressures. You normally shouldn't have to adjust the ideal pressures with the + and - buttons. If you re-download the app and replace the IdealPressures.ini file, you'll get all the default ideal pressures again.
The Escort is 37 front and back.
-
Re-download seems to have fixed it, thanks

Something keeps changing my ideal pressures, maybe content manager? Further investigation required

The app only reads the pressures from that IdealPressures.ini file.
Maybe there's some errors. If you attach your py_log.txt from your logs folder next time you see this behaviour, I'll see if there are any errors in there.

Just an observation Wally.
When you say 'saves', do you mean permanently?
Mine only stays 'set' while I'm in the session, if I leave and rejoin I have to set the ideal pressure again.
Obviously this is in regards to mods only.

Yes, it is permanent, but I can't remember how it works for mods that don't already have an entry. It's possible that that scenario doesn't work.

Tested with:
F5000 Surtees (in Hotlap mode)
ACL Corvette (online)
Formula RSS 4 (single, race weekend)
All pressures were random and I've DEFINITELY altered these before.
The only mod I remember NOT having to adjust was the can-am.

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.

Thanks wally :)

Sounds good Wally. Thanks.

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??

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?

Just did a few laps in the lotus at QLD, and got around 350 for Corner and around 180 for Average consistently
across a number of laps.

Yeah, you don't have enough ARB adjustment in the Lotus to really balance it, but you can improve the weight transfer distribution.
-
Does the 'corner' reading change through the corner?
I saw some high figures there and assumed that it was the 'last' reading, ie. corner exit only, as I was looking at the apex during cornering and not the app.

The corner figure is a running average as you go through the corner. So by the time you exit the corner, the last number is the average over the whole corner.

Oops... the corner figure was stuffed. It wasn't resetting after each corner. Now fixed. Please re-download!

So are the big numbers saying it has a lot of front weight transfer. I can't see it getting to negative!

EDIT: Seeing negatives now, along with positives.
-
Last change...... :o
I added the average for all corners over a lap, so you have:
Last Corner = the weight transfer delta for the last corner (final figure on exit is the average for that corner)
Lap Avg = the average delta over the whole lap
Corner Avg = the average delta, over the whole lap, but just while cornering.

Hey, I updated this app in the first post to make it use a little less CPU (not that it used much to begin with, but it's improved now).
