Automobilista 2 - Extended Car Info Spreadsheet

Thank you. This information comes from Reiza and the vehicle selection Ui. Their Formula Vee version has this listed as a S4. Do you know when this changed from F4 to S4? If this is wrong then a bug will have to be raised to have the vehicle Ui info fixed..

On a side note I am also chasing a year information for these vehicles. If you know please shout out..

 

@Coanda

 

v0.9.5 (OP Updated)

- created Google Spreadsheet. Link is in the OP
- updated power steering indicator for various vehicles
- updated GTR Ultima (640) and Copa Truck shift type

 

This is how Reiza have it set in the game. The latest two versions have VW and Fiat added for Copa..

 

If anyone has the following vehicles in iRacing please let me know as I would like the Steering Force information that is logged from iRacing through Motec.

- Williams FW31
- McLaren MP4/30
- Lotus 49
- Lotus 79
- Skip Barber F2000
- Porsche/Audi LMP1
- Nissan GTP ZX-T GROUP C
- Aston Martin GT1
- Porsche 911 RSR
- Ferrari 488 GT3
- Mercedes AMG GT3
- McLaren 570s GT4
- Porsche 718 GT4
- BMW M4 GT4

@Peter Stefani - The Wheelbase, Track & Tyre dimension columns have been added to the google sheet that is linked in the OP (new link). If you can add the data anytime in the future that would be grand.. Thank you!

 

I plan to do this when I have time and also add more engine info.

 

@Peter Stefani - Thank you for adding that info..

 

It's a bit different here, than ACC, for example.

The "recommended" cold-values are already set by default, but they will vary, depending on downforce, suspension/camber, track and weather.

Also it can pay off, to run lower pressures, but tires will degrade with tearing/graining/blistering, if handled/breaked in wrong or weather is extreme in temps.

You have to adjust your ideal contact to the road by the I/M/O temperatures method. Outside a bit colder than inside in a range of 5-7°C
(Front can have more difference, than rear) and the middle one inbetween this range, but not hotter or colder than I and O. (Determinated by camber setting)

The middle temps will tell you, if your tire pressure is too high or too low. Too low M temps in relation to I and O means pressure should be too low, if i'm not totally wrong right now. (Middle temps tell you, if there is contact patch to the road on the middle of the tire, causing it to heat up to begin with)

It's not hitting magic numbers, but finding approximation to a uniformly heated and settled tire. I hope, that was a bit helpful. ' (Had to edit it a few times, not gonna lie, i'm really rusty )

 

The default cold recommendations (to reach safe hot pressures) are set already in the defaults. (Should be, at least)

The manufacturers-"optimal" tire pressures for many cars aren't "optimal" though and rely also on camber and other things for example. Also in real life teams usually run hot pressures under the manufacturers recommendations as far as they can get away with.

Here an example for the Michelin, that is on the Porsche Cup and why it isn't that easy:



This doesn't mean, AMS2 does it spot on, of course, but i don't know any racing sim, that does it completely right, without some "fudges" to achieve the goal.

 

These recommendations of manufacturers are more recommendations to keep the tire surviving its lifespan, than "optimal contact patch".

The true "optimum" of a tire more likely depends on several things, that i'm to stupid to explain ( ), but it's for sure load and weather dependent etc. and which goals you are aiming for...it's not a magic number, you hit and you have suddenly better grip. ^^'

 

I think the upper one is the one. (And surprisingly it also fits with recommendations)
(27/65-18)

The bottom ones are HUGE

And again: A manufacturer will not give you the ultimative "optimum" pressures, but a safe recommendation for something, that makes you survive your run. I'm very sure, the teams also would stay under 2 bar with the 31 for sure.

 

That applies to the F309. What about the F301..?
