QUESTION AI fuel usage problems?

[rageman002]

in the file "car.ini" add extended like this:
[HEADER]
VERSION = extended-2

and in the "engine.ini" file add these:
RESPONSE_TIME = 0.03 ;response delay in seconds
MECHANICAL_EFFICIENCY = 0.85 ; % / 100 - should match "transmission losses" multiplier
IDLE_THROTTLE = 0.04 ; % / 100 - how much throttle is used to reach idle
IDLE_CUTOFF = 1800 ; revs at which the throttle ceases to idle

[FUEL_CONSUMPTION]
THERMAL_EFFICIENCY_LUT = ; torque_ratio | thermal efficiency of the motor
THERMAL_EFFICIENCY = 0.35 ; lowest value = increased consumption
FUEL_LHV = 43 ; lower calorific value of fuel - MJ / kg
TURBO_EFFICIENCY = 0.8 ; optional: how efficient the turbo is at generating power from more fuel
LOG_FUEL_FLOW = 0 ; if 1, the current flow rate will be recorded in custom_shaders_patch.log

naturalmente devi usare ContentManager e CSP

Hey! Sorry to revive this old thread, I can't get this to work. Do I also need to put extended-2 in the engine.ini?

"
RESPONSE_TIME = 0.03 ;response delay in seconds
MECHANICAL_EFFICIENCY = 0.85 ; % / 100 - should match "transmission losses" multiplier
IDLE_THROTTLE = 0.04 ; % / 100 - how much throttle is used to reach idle
IDLE_CUTOFF = 1800 ; revs at which the throttle ceases to idle
"
Where do I put these in the engine.ini exactly? Anywhere will do or under a specific section?

And do I need to enable an option in CSP to activate this?

Will this both change the car's fuel consumption, as well as the AI's fuel management?

Thanks

Edit: I tried enabling the LOG_FUEL_FLOW = 1, but I see nothing in the custom_shaders_patch.log.

I copied my post to you in this thread where I have already explained everything, read it step by step and it will work. LOG_FUEL_FLOW doesn't matter you put 1, it just enables you the log script. As for your question, if this also affects the consumption of the AI, well I would say yes, the AI uses the same mod as you, so it will have the same consumption calculations as you.

I tried this, it doesn't seem to work.

in game you should open the AI app and do a couple of regular laps and press the "SAVE CONS" button that you find in the AI app that opened to you, it automatically generates the "fuel_cons.ini" file with the estimates of the consumption that your engine has based on the power, the aerodynamics, and the weight of your mod. The file will be generated in the "data" folder
If you want to start you can copy the file that I have attached to "data", then later create your own.
Also remember to delete the "data.acd" file inside the main folder of the mod, because if it is present, assettocorsa will not read the files inside the unpacked "data" folder, but it will read "data.acd" and your changes will not work .

I got it to work! Turns out the way you write the extended-2 part matters.
[HEADER]
VERSION = extended-2 <-- not good
VERSION=extended-2 <-- this works

Now I have a weird issue where the AI just spins its wheels endlessly once I've enabled that. I tried driving the car myself and it works fine, only the AI has issues. I tried it on another car and there was no issue with it. Seems like its car-specific.

It appears to be only when they are trying to leave the pits. I tried starting a race and it worked fine there too, any idea what's going on here and how to fix it? I attached a screenshot to show what's going on, it's like the car has 0 grip somehow.

Try sharing the mod if you want, and tonight I'll try if I find the problem

 

[rageman002]

I figured it out, it was the tyres.ini, I swapped it with a kunos car and now everything works fine!

Thanks for your help!

Ok I just ran into another car having the same issue, and with this one changing the tyres.ini doesn't seem to fix it.

In the custom_shaders_patch.log, there's an entry:
2022-06-19T01:20:09:481 [14168] | INFO | Detected suspension travel for `osella_pa21_honda` (wheel=0): 0.30895

So I'm thinking it's about the suspension bottoming out, but I tried changing various settings in the suspension.ini and setup.ini but I can't figure it out. Any help would be appreciated!

Edit: I found the issue! The PERFORMANCE_CURVE= was mislabelled, and apparently once you put the extended header, it breaks things.
