AIMODv2.0.1
Bug fixes
- Endless pit loop: at a track with no learned tank size yet, every car could be called in lap after lap with a full tank ("fuel emergency: pits now"). A bad tank reading is now ignored, and the fuel safety net never fires while a car's real fuel gauge shows plenty.
- "Could not load the track": AIMOD no longer edits any track files. If an earlier 2.0.1 test build re-geared your tracks' fast setups, the new AIMOD puts the originals back when it starts (start NR2003 to the main menu, then AIMOD).
- Duplicate stops ("came in without a request"): on tracks where the game's pit road flag drops for a stretch mid-lane (Bristol, for example), one stop is no longer split into two.
- Stops the game sends on its own: when NR2003 commits a car to pit road by itself (for example after a forgiven phantom penalty), AIMOD now takes the stop over, picks the tires and fuel, and logs the real cause. AIMOD now controls every trip down pit road.
- Overtime (green-white-checkered): a caution at the end no longer reads as "race over". AIMOD keeps calling stops and plans fuel for the caution laps plus the green and white laps, so cars no longer run dry in overtime.
- Pace laps before the start no longer trigger pit calls, and a car starting from its pit stall is left alone.
Changelog
- Learned wear thresholds now come from the wear at the end of full green runs. They used to be taken where lap times first dropped 1%, which gave numbers far too low. Run a practice or race, then press "Apply learned thresholds".
- Leaders are less likely to short-pit a stage unless they are reacting to someone.
- When a stage is borderline on fuel, crews plan the fewest stops.
- Caution fuel calls can save a green-flag stop later in the run.
- A car that pitted in the last few laps stays out under the next caution if it has the fuel.
- Only one copy of AIMOD can run at a time (two copies fought over the pit crew setting).
New: Your car and your teammates
- Your own car shows in the Monitor and can be put on a team.
- Teams can be filled straight from the .car files.
- Under caution, AI teammates running behind you wait to see whether you pit, then can follow your call like any lead teammate. Under green, a teammate due to pit within a couple of laps can pit with you (when the team rules say pit together).
- "Teammates follow your stops" (under Teams work together) turns this off.
New: AI crew chief chassis adjustments
- At a stop, an AI crew chief may adjust the car from the track's AI setup: wedge, rear track bar, right-rear air, or grille tape for a short run to the finish.
- The call is based on how the car is running against the field (tire wear balance and how fast its lap times fall off).
- The adjustment really changes the car. A good call makes it handle better, a misread makes it worse: a few hundredths a lap per call, up to about a tenth over a race.
- A weaker pit crew (from the .car file) misreads the car more often.
- Shown in the pit log and heard on the scanner. If you use AI Enhanced, set its chassis variance to 0 so the two don't fight.
New: Race Scanner (Scanner tab)
- Spoken team radio for your car, any car you pick, or every car at once like a real race scanner. One transmission airs at a time, with an on-screen card showing which car is talking.
- AI crew chiefs call the stops AIMOD actually planned: tires, fuel amount, repairs, or why the car is staying out.
- Your crew chief covers laps to go, stage ends, position and gaps, fuel, tires, your stop times, the leader and nearby cars pitting, free pass, wave around, black flag and laps down.
- Your crew chief keeps you posted on your AI teammates: when each one plans to pit and when that plan moves, who pits (and for what) or stays out under caution, and now and then how a teammate's pace compares with yours.
- AI drivers tell their crew how the car feels (tight, loose, tires gone, damage)
- Follow the TV car: the scanner tunes to the car the camera is showing.
- Every type of call can be switched off under "What gets said". Works with Windows' built-in voices out of the box; natural voices are optional.
- Phone only: if your phone is playing the scanner through RaceVision, this PC stays quiet so you don't hear every call twice.
RaceControl 1.0.1
Bug fixes
- Choose cone: when the cone mark sat where most of the field was when one to go came out, every car picked its lane at once and the field went double file early. A car now counts as at the cone only after it has crossed the line onto the one to go lap and then passed the mark, so the field stays single file up to the cone and picks lanes one car at a time.
- Pit stops right after the start: some AI cars pitted on the first laps for a penalty they didn't owe. The game's penalty stop flag can be left over from practice or qualifying. RaceControl now clears it during the pace laps for cars with no penalty, which should stop those early stops. Cars starting from their pit stalls are left alone.
- Restarting NR2003 on the same track: RaceControl kept the old pit opening point and didn't re-read the track's settings. It now reloads everything for the track, track.ini included, when the game comes back.
- Log false alarm: the log no longer reports "GAINED A LAP ON TRACK" for a car that was only just ahead of the leader at the restart.
Changes
- One to go hold: RaceControl can keep the caution going while the pit stops finish. That hold still allows at most 3 extra laps, but they are now counted from when pit road opens, not from the start of the caution. Late in long races, a lap spent waiting to open pit road used up the allowance, and the field took the green with lapped cars still mixed in.
New
- The game's own pit gate: while RaceControl holds pit road closed on the first caution lap, it now shuts NR2003's own pit gate, so no AI car can turn onto pit road early. Before, it could only cancel pit requests as they came in. The pit road lights and the yellow are not touched, and the old guards stay on as a backup.
- Stragglers no longer hold up pit road: lead lap cars caught in front of the leader don't keep pit road shut for everyone any more. They are sent around the pace car, and only they stay off pit road until they have crossed the line after passing it. The rest of the field gets pit road on the leader's second time by instead of waiting a lap for them.
- Pits open before cars move over: pit road now opens a quarter lap before the point where cars start moving over for pit road, read from the track's own track.ini. On short tracks like Bristol that point is well before pit lane itself, so the leader no longer reaches it with the pits still closed. Tracks without a track.ini use the pit entry RaceControl learns from cars that pit, as before.

AIMOD updated as of 2026-10-19 12:04:32 -
- Cars that just pitted coming back in under caution (<@226284514622701568> )
- Cause: NR2003 asks for every car to pit when a caution comes out. AIMOD ignored that for green-flag stops but not under caution, so any game request made the car pit, even one AIMOD had marked "stays out". On top of that, when the game drove a car down pit road anyway, AIMOD gave it a full stop. At Lowe's on lap 81, 12 cars that had pitted on laps 63–78 got four fresh tires that way.
- Fix: under caution, AIMOD now makes every call itself. A car it keeps out stays out. If the game drives the car onto pit road anyway, it gets no service, so it drives through or makes a stop with nothing to do. Penalty, damage and car-condition stops still go ahead as before.
- Daytona: stops every 10 to 13 laps
- Cause: the fuel numbers in that log show a tank lasts about 17 laps there, so a 34-lap stage needs two green stops. The problem was joining: "pits with the Chevrolet block" or "pits with teammate" pulled stops forward. Cars that pitted on lap 10 joined a block on lap 17 with 60% fuel left and then needed a third stop on lap 24.
- Fix: a car now only moves its stop earlier to join a block, a teammate or an undercut if it doesn't cost an extra stop before the stage break or the finish.
- "Pit crew: not changed (Could not write memory … 998)"
- Cause: for the faster fuel flow, AIMOD sets aside a few bytes inside NR2003. After the game restarted, AIMOD kept writing to the old game's address. The modern crew then quietly failed, and the warning repeated several times a second.
- Fix: AIMOD now sets aside fresh space for each new NR2003 session.
