You decide how much fuel to save or how much boost to use per lap. We work out the exact spots for it from your own laps, and the overlay shows them to you live, lap after lap.
The lift-and-coast plan works with laps from every sim. In the car, the overlay shows it live in Le Mans Ultimate and rFactor 2 today, the other sims follow. Push to pass only exists in rFactor 2, the only one of our sims that has it.
Colour: fuel saved per second lost, per braking zone. Green is cheap, red is dear.
Grey is the reference lap at full throttle, orange the same lap with the lift your setting asks for. The car coasts, so the brake point moves towards the corner.
The same zone, replayed at real speed. The bars close in over the last 160 m, a short tone marks the lift, then the overlay counts you down to the new brake point.
The plan comes from 85 real laps. Every zone has its own price, and the maximiser always buys the cheapest saving first, across every braking zone of the lap.
Every extra lap on a stint saves part of a pit stop, and costs lifting on every lap. The strategy calculator weighs both, lap by lap, and finds the length where the average lap including the stop is quickest.
| Stint | Save/lap | Lifting/lap | Stop | Stop/lap | Average lap |

Same plan as above: Oreca 07 at Le Mans, 6.36 L per lap, a full 75 L tank as in a real long run, and the reference lap of 3:34.732, with a 30 s drive-through and refuelling at 2.5 L/s. In the calculator you set your own values, and fuel weight and the tyre curve from your own laps come on top, and with them your tyre strategy: fresh tyres or a double stint.
The strategy calculator turns a longer stint into a saving per lap. The maximiser spends exactly that saving where it costs the least time, and in laps mode the overlay recalculates it live from the fuel in the tank and the laps left.
Each braking zone has its own curve of fuel saved against time lost. The maximiser keeps adding lift where the next litre is cheapest, until the target is reached. No zone gets more than it is worth.
A coasting car arrives slower, so it can brake later. The new brake point comes from your own braking, worked out again live from your current speed.
Set the boost budget per lap. Every straight gets its curve of time gained against energy used, and the budget goes where it buys the most. Block sections, set a minimum boost or a maximum number of zones. In rFactor 2.
The overlays count you down to every lift and boost point, with a tone you can time ahead. You drive the plan without thinking about it, at the same spots every lap.
The plan is built from the laps you drove: your coasting, your braking, your fuel use. Change the car or the track, and you get a new plan.
Write to us and we answer by e-mail, usually within a day. For a coaching session tell us the sim, the track and what you are chasing, and we come back with times that fit.
Record it, and the corners that cost you time are waiting for you when you take the headset off.
