AI Pit ControlPRO — "Stage 2" is now available
Hi all,
For everyone using AI Pit Control Lite:the bigger system I've been building — "Stage 2" — is now live.
AI Pit Control PRO now exists as a separate, more advanced two-app version.
Rather than write the whole thing out here, I've put together a full walkthrough that shows it running and covers where to get it:

First things first Lite isn't going anywhere.
AI Pit Control Lite stays right here on gtplanet, free, with full support. Nothing about that changes.
PRO is simply the bigger option for people who want full race strategy control.
What AI Pit Control PRO does (available now)
Lite gives your AI a working pit trigger. PRO plans and runs the whole race:
- Real race strategy — plans the full race up front, up to 8 planned stops, with each car's pit window worked out from its own measured fuel burn, not a flat percentage.
- Independent AUTO mode handles mixed grids — because it plans each car from its own fuel burn and its own tank size, a field of cars with different-sized tanks all get a correct strategy: the small-tank cars stop when they need to, the big-tank cars run longer, no manual tuning.
- Independent AUTO mode handles mixed grids — because it plans each car from its own fuel burn and its own tank size, a field of cars with different-sized tanks all get a correct strategy: the small-tank cars stop when they need to, the big-tank cars run longer, no manual tuning.
- Field pit-stop staggering (both modes) — PRO sizes each car's stints to slightly different lengths, spreading stops across up to 5 groups (±2 laps) so the whole grid doesn't converge on the pit lane the same lap. Every car still pits at the end of its own stint — it's the field that's spread out, not the individual stop.
- Two strategy modes — F1 Cars Only gives each car a tight, single-lap pit window at the end of its stint (authentic F1-style racing, with the field staggered as above so they don't all pit together); Independent Strategy uses a wider 75–95% window, tuned per car.
- AUTO or USER stop counts — let PRO decide, or force a specific count (0–8) yourself.
- Pit-Time Normaliser — scans every AI car's refuel rate and can equalise the whole grid, so no car gets a free pit-time advantage from its data files (with automatic backup/restore).
- Robust fuel delivery — confirms every fuel write actually landed (within 0.5 L), clamps outlier readings, and caps fuel so a car stopping two laps from the end doesn't take a full tank.
- Setup that locks in — your mode and plan stay editable in the box, then lock when you leave the pit lane, so practice calibration can't silently disagree with the race.
- Validation before the race, not during it — a forced stop count that won't fit the race is caught at setup, and the tracker/estimator all agree on the count PRO will actually use.
- Smarter tracker & estimator — car emblems, awareness of PRO's plan, per-stop history, and a warning if any AI tank is too small for the stint.
The roadmap — where PRO is heading
This is the plan for PRO subscribers,and it's the reason I split the project into stages:
🛞
Tyres & wear (next)
- F1 becomes a real F1 strategy — tyre stops only, no refuelling. Fuel is set to last the full race (just like modern F1), so stops are driven purely by tyres. Pick a wear level and get a real number of stops — each compound gets a declared tyre life that scales with the 1×–5× wear dial,shown for your track and race length before you start.
- Independent mode calls a car in on genuinely worn tyres (dry and wet) — reading each car's live wear, not a table, so it works on any car and compound.
- Wet-tyre racing — the AI switches to wets when the track turns wet and back to slicks once it dries; a weather change is its own kind of stop (no fuel, doesn't burn a planned stop).
Lite gets live per-car tyre wear in the tracker, and stops/tyre-changes counted and named separately (Weather / Tyre / Tyre+Fuel / Unplanned).
🌧️
Full weather strategy(after that)
- F1 Cars Only races in the wet too — full wet strategy with a live wear check underneath.
- The field changes to wets before the rain arrives (reading AC's forecast — around three laps of warning in testing), instead of arriving a lap too late on the wrong tyre.
- Lead time scales with how hard it's about to rain, and cars are released in groups so the pit lane doesn't jam.
I'll keep supporting Lite here as always.
Thanks to everyone who's tested, reported bugs, and pushed this thing forward — it genuinely wouldn't be where it is without this community.
