How to use it
- Enable Strategy and Fuel laps remaining and pit strategy for the standalone fuel-lap warning family. Enable Fuel level warnings for percentage thresholds.
- Complete suitable laps before expecting a fuel-laps estimate. The rolling model uses accepted measured consumption, excludes affected refuelling/out/in-lap samples and does not equate missing estimates with zero.
- Treat laps remaining as an estimate based on recent accepted consumption. Changed driving, car, fuel usage or refuelling can change it.
- Pit this lap uses the intentional conservative threshold of 1.10 laps or less, when an estimate qualifies. Its independent haptic option can be enabled separately.
- Pit exit summary reports available fuel facts after authoritative refuelling/pit-mode exit. The app does not infer a physical pit boundary solely from a map.
Options and defaults
| Control | Fresh default | Values / action | Condition or meaning |
|---|---|---|---|
| Fuel laps remaining and pit strategy | ON | On / Off | Strategy; reliable learned estimate |
| Fuel level warnings · 50 / 25 / 10% | ON | On / Off | Strategy; valid percentage |
| Pit exit summary | ON | On / Off | Strategy; authoritative pit/refuelling exit |
Operating principle and expected output
Fuel level warnings cover 50 / 25 / 10% crossings and the critical/zero-fuel conditions supported by current source. Flags belong to a fuel cycle and refuelling can reset the cycle. Fuel wording avoids decimal lap counts: 2.00–2.50 is approximately two laps; above 2.50 and below 3.00 is less than three laps; 3.00–3.50 is approximately three laps.
When output is absent or limited
No clean consumption sample means no reliable lap estimate. Pit mode suppresses routine lap reports and some performance information. Safety ON alone does not enable fuel voice; Strategy owns it. Timed-race finish uncertainty does not cancel a qualified Pit warning.
