Are there any fixes for the AI on the intermediate and short ovals? Been working on a custom fantasy IndyCar season with the SF23 and the AI is TERRIBLE at Northern Isle and Blue Moon. I'm at the point where I'm literally trying to figure out top speed limit for myself with transmission gearing. Legitimately debating turning down the tire wear rate and trying to slide around on inters to see if it's closer to parity 😭. I did a 180 lap race at Northern Isle and finished 11 laps ahead of 2nd and the AI cars Lepage the field every out lap.
This is probably less about “AI on ovals” and more about Reggy/non-Sophy being rigged to lose to the player. Watch a replay, the opponents/AI drive at less than full throttle after the first turn. You aren’t crazy / you DO need to slightly downtune your car as you launch the race, in order to approximate a fair fight. I usually do like 8+/- on the power restrictor (so, 92ish, from 100), but that number can differ depending on the grid. I save it as a separate tunesheet and flip to it in the pre-race. Important to build the habit of flipping back to the ‘balanced on paper’ tune before you get out of the car.
This won’t help with their pit entry/exit behavior, but you can work to make it roughly equal in terms of the power of the cars. You’re still racing Reggy, though. I have a spreadsheet I keep (integrale docs in sig) of how I think Reggy performs at the various layouts, if interesting. Some are just too immersion-breaking for me…
Last comment that may play into your BoP - natural downforce and aerodynamic potential of the cars. I found that, even with otherwise-equal tunes, when I was testing the Mustang ‘15, Camaro ‘16, and swapped Crown Athlete (‘13?) as my NASCAR trio at Daytona, they would still reach different top speeds - all slightly beneath the custom-transmission-set top speed in the tunesheets. This may not apply at Northern Isle, but a general concept to keep in the back of your mind in case you’re struggling for that last bit of balance.
This is an additional setup trick you would use in addition to the usual “boost = weak” and “rabbit/pace car” methods.
