Features
Gary is a crew chief and a spotter on your radio. The idea is simple: anything you’d glance at an overlay for, he either tells you when it matters or you can ask him for it.
Most of it works the same in both sims - lap times, fuel, gaps, flags, the pit sequence, voice questions. Each sim also has things only it can do, because each one exposes different data.
In both sims
Crew chief and spotter. Two separate voices. The spotter calls cars alongside, which side cleared, and three-wide (and which side of the three you’re on); the crew chief handles everything else. Both voices run locally on your PC - no cloud, no internet needed to talk. The spotter can also use a recorded voice pack, including the spotters from CrewChief.
Lap times. Your time after each lap and whether it was good, with where you found or lost it - either as a sector rundown at the end of the lap or live, sector by sector (your choice in Settings, or just tell him). A lap that doesn’t count - off track, cut a corner - gets its time and that it’s gone, never “personal best”.
Turn by turn. In practice, qualifying and testing, say “turn by turn on” and after each lap - or each sector, if you ask - he tells you which corners you lost or found time in against your best: “Lost two tenths at Turn 1, got a tenth back at the Esses.” Never automatic in a race. “Where did I lose time” works in any session, and in a race “where am I losing time to the car ahead” (or behind) goes corner by corner through the fight. Needs a track Gary has corner data for.
Fuel. Measured every lap. Warnings when you’re getting low, a consumption summary, and “fuel to the end” to work out exactly what you need. Turn on automatic fuelling and he sets it for you every time you turn into the pits in a race, then tells you what he set. He calls the fuel window once, the first lap a stop gets you to the finish - and with automatic fuelling on, confirms he has the numbers and your margin before you commit to it. Series fuel limits are taken into account.
Saving a stop. When saving a little fuel would finish the race on one fewer stop, he offers it: “We can drop a stop if you save a bit - 2.5 liters a lap instead of the 2.6 you’re using. Want to go for it?” Say “yes” and he gives you the burn after every lap (“2.53 liters that lap, on target”), tells you if the target moves, says when the stop’s saved or can’t be saved any more, and after a few laps whether the lift is costing you more lap time than the stop would. Say “no” - or ignore it twice - and he leaves you alone. “Let’s save fuel” or “forget the fuel save” change your mind any time. The target includes your fuel margin, but he won’t offer a save when the margin is all you’re short of, or with fewer than 4 laps to go.
The pit window. Once the fuel says a stop now won’t add one, he checks every lap whether you’d rejoin in clean air or in traffic - any class, any lap - priced on the stop you’ll really make (the fuel going in and the tyres you’ve selected): “Box this lap - you’ll come out in clean air” or “Not this lap - you’d come out 1.2 seconds behind the #23.” If fuel gets short and the traffic hasn’t cleared, he tells you to box anyway.
The pit sequence. What the stop should cost, said on the way to the pit entry so it’s done before the countdown starts; pit limiter reminders, a countdown to your box, the release (“go, go, go”), a heads-up about traffic when you merge out, and a reminder about the pit exit line. Ask “where would I come out if I pit now” or “should I box this lap” and he’ll tell you.
Gaps and racing. Gap to the car ahead and behind and which way it’s trending, calls on passes as they happen, the class leader pitting, rivals pitting, position updates.
Multiclass. Faster classes coming up behind, slower traffic ahead, lapped cars, blue flags (naming the class of the car lapping you) - and class-best lap times so you know where you stand in your class, not the whole field.
Flags and incidents. Yellows, sector yellows, debris, black flags, off-tracks, spins, damage, and a rejoin warning if something’s coming when you’re stopped on track. When a rival ahead of you stops on track he says who - and in iRacing, where: “stopped on track at Turn 3”.
Penalties. What you got, how many laps you have left to serve it, and a reminder in the last sector on the laps that matter, so you’re not finding out at the pit entry.
Setups. When practice turns into qualifying he reminds you to load your qualifying setup, and when qualifying turns into the race, your race setup. Not in a fixed-setup series.
Race start. A grid briefing - length, your position, how many stops and the lap the fuel window opens if it needs any, tyre allowance, anything unusual about the rules - a reminder to get heat in the tyres before the green, and a warning if you’ve gridded with less fuel than the race needs, with how much it does.
A bit of personality. Now and then in a race he says something that isn’t about the car - a long battle, a rival in trouble, a clean run, the last few to go - never more than a line every few minutes. After you cross the line he gives his take on how it went against where you were expected to finish (your rating in iRacing, your grid slot in Le Mans Ultimate). With Let the crew chief swear on, some of it is a lot less polite.
Weather and track. Rain starting, the track getting wetter or drying, track temperature swings, and “should I be on wets” when it’s in between.
Race prep mode. For practice stints: do a run, and on the way down the pit lane he debriefs it - fuel use, pace, and how much the lap times fell away over the stint.
Turn names. At tracks Gary has corner data for, calls use the corner names (or numbers, if you prefer - just say so). Corners a track officially letters, like 5a, 5b and 5c, are called that way, so the numbers after them still match the track map.
Gaps every lap, on request. “Give me the gaps every lap” (or every few laps, or one side only) for a fight at the end of a race - how far ahead and behind, and how it moved that lap.
How much he talks. “Quiet mode” for only the urgent stuff, “keep me informed” for everything. He also holds routine chatter while you’re hard on the brakes.
Captions. Everything the crew chief says - and the spotter too, if you want - as text in a small box over your sim, wherever you put it. For drivers who are hard of hearing, race with the sound low, or just missed a call. See Settings.
Talk by name. Turn on the wake name and say “Gary, how much fuel” - no button needed.
