    Been doing some 'endurance' racing against AI. 2.5 hour real time races at x5 time scale so approx a 12hr race. I like to experience the Pit Stops but not bothered about gaining time against AI through Stategy.

    I set an increased Fuel rate to ensure a few pit stops and tyre wear to zero for consistencty and eliminate that from potential pit strategy. I did the same stops as most of my class of car (Log Analyzer) but I feel I may have gained time in the stops.

    I beleive AI will always fill fuel to max tank at every stop. So I have been doing so as well.

    My main question is do they always change all 4 tires on every stop. Regardless of wear (or lack of it)?

    Looking around on the forum it sounds like this could be car specific? With settings for tire changes and how long it takes.

    In my last race I was the S397 Callaway, against all Apex GT3 Mod cars. (Performance is well balanced)

    Is there a known default for S397 cars? Or any popular mods for that fact.

    Cheers

    I can't speak for rF2 cars, but in the previous generation the AI would consider how many laps were left and estimate at least the last fuel stop to have enough fuel to finish. However, things like accelerating the fuel consumption tend to magnify small inconsistencies into large problems. I guess the 'test' would be to compare the pit box times during the event with the last stop. If that is noticeably shorter in duration, then at least part of your question will be answered.

    Yeah, I probably need to do some controlled testing with the AI. Time is limited though and i just like to 'play' :D

    I have Log Analyzer but on the Pit section it just says the 'old' and 'new' tyre (sorry not at PC) as the same for me even though I didn't change tyres so not sure if this can be used. Though I may be missing something, relatively new to Log Analyzer. I'll take a close look at it and the options.

    Running rFactor2 Log Analyzer tells me what tyres AI change (soft, medium etc.) which lap they do this, what tyre wear AI (and real drivers) pitted and finished on, how much fuel they start with, pit for and finish with.
    This data I use to set up our private server as we race the F1 season (and GT3 season in winter) with 2 real drivers against 18 AI.
    The interface has many hidden facets, you just have to click around and scroll.
    I would be lost setting up the server without it ! Great program ;)

    @ceecee Agreed, great program. But does it explicitly say when there is no tyre change? I know I did not change tyres on any stint but couldn't see that info. Like you say I'll spend some more quality time with it :)

    Here is an AI at a 18 lap F:5x T:5x D:15% Barcelona race under R sectors/Laps tab.
    The numbers on the far left in the red box are tyre wear LF/RF, LR/RR.
    The graphs in the 2nd row from the left is the visual tyre wear.
    When they pit on the 10th lap the LF/RF numbers have dropped from 91,4 92,2 (on the 1st lap) to 17,6 25,9 when pits. In the graph you see AI gets new tyres, to the right it denotes Soft tyres.
    If tyre wear is off then the numbers will remain constant. (and no changing of tyres)

    To my knowledge ai always take on 4 new tyres when they pit. And they always take a full amount of fuel even when they have to do 2 more laps until the race end. So ai pitstop times are constant accept when they have extra repair time when damaged. The pitstop time between different cars may vary though.

    @ceecee Thanks. Seems simple when somebody points out the obvious. I've looked at that (though I'm sure the layout is slightly different on my screen) and thought "oh yeah I see what thats saying". But now I really see what its saying!

    I no longer have the GT3 logs where we stopped for fuel and tyres, in F1 there is no refueling.
    But pitstops among the AI do vary in time, the starting fuel is never the same (at least in our mod) so the time taken at the pitstop can vary along with the times as seen in the bottom graphic. Gap is the difference from the quickest pitstop to the slowest.
    This has been similiar with damage on or off. (the hard and medium tyres are a glitch in the mod readings, we were all on soft)

    I have been using rFactor2 Log Analyzer for some years now, I am still finding (or understanding) new data (that has been there all along !) and still have not figured out the meaning of some data (consistency to name one).
    Between Nibo's rFactor2 Log Analyzer, Mr. Belowski/The Iron Wolf's Crew Chief, Gerald Jacobson's rFactor2 Weather Tool and some other specialists, we are seriously spoilt here, I believe :D

    Ok. So on the pitstop summary is Time the total time in pits (including entry and exit) or just the time in box? I'm now presuming total time. The Tires In and Out on this screen is a bit confusing on my AI race as technically with no wear there should have been no change but it shows as same tire in and out. Obviously the 'no change' may not be interpreted here.

    Going back to your screenshot in post #7 Is that the Stints tab? Mine looks a bit different (v2.057). Unfortunately this seems to only show for me and not the AI which would have been interesting.

    Total time in pits, it takes only a couple of seconds to change F1 tyres (not like GT3 when we could have a drink and relax for a minute :D). So probably measured from pit entrance to pit exit.
    Tires In and Out, you should check the red box denoted R sectors/Laps tab to see what the tyre wear was on the pitstop. The graph will go from small brown lines to long green ones again if they were changed.
    Column 1 is laptime, columns 2-4 are sectors, column 5 is fuel.

    I am only using the DEDI version on my server but in the Administrator settings there is a box you can check to record AI data if I remember correctly.
    See if you have the same in the standalone version.
