Engine Clue Calculator
Example Data Table
| Gas Clue | Hose Clue | Pressure Clue | Likely Engine | Reason |
|---|---|---|---|---|
| Deuterium | 3xH | Greater than | #12 | Gas, hoses, and pressure all match. |
| Helium | 2xH | Greater than | #6 | Helium with two hoses and high pressure. |
| Nitrogen | 3xH | Less than | #8 | Nitrogen with three hoses and low pressure. |
| Deuterium | 1xH | Greater than | #2 | Single hose Deuterium high pressure match. |
Formula Used
The calculator uses a weighted clue score. Gas match receives 40 points. Hydrogen hose count receives 30 points. Pressure direction receives 30 points.
Confidence = matched clue points ÷ available clue points × 100.
Bar estimate = PSI × 0.07. Use this when the computer gives a PSI reading.
Estimated gross = contract payout + bag value total + escape bonus - wrong attempt penalty.
Crew share = estimated gross ÷ crew size. The risk index increases when clues are missing, confidence is low, or wrong attempts rise.
How To Use This Calculator
- Select the gas clue from the note.
- Select the hydrogen hose count shown by the clue.
- Select the pressure direction from the computer.
- Enter the PSI value when available.
- Add payout, loot, crew, and attempt details.
- Press the calculate button.
- Read the result shown above the form.
- Download the CSV or PDF report when needed.
Payday 2 Big Oil Planning Guide
Why Clues Matter
Big Oil rewards calm observation. Day Two looks chaotic at first. The lab has many engines. Only one engine should leave. A wrong pick wastes time. It can also raise team pressure.
How The Tool Helps
This calculator turns scattered clues into a ranked decision. It checks the gas clue, the hydrogen hose clue, and the pressure clue. Each clue narrows the engine list. When all three clues agree, the best match becomes clear. When one clue is missing, the score still shows likely choices.
Reading The Evidence
Start with the gas note. The game uses Deuterium, Helium, or Nitrogen. Match that clue with the small tank shown on an engine. Then read the hose clue. It may show H, 2xH, or 3xH. That means one, two, or three hoses on the blue hydrogen tank.
Pressure And Planning
The pressure clue comes from a lab computer. The useful part is the direction. Less than points below the reference range. Greater than points above it. The calculator also converts PSI into bar. The common shortcut is PSI multiplied by 0.07. This helps crews compare the computer clue with the engine gauge.
Advanced Heist Choices
Advanced options add heist planning value. Wrong attempts estimate extra risk. Loot bags and payout fields estimate team value. Crew size gives a rough share. These numbers are not official rewards. They help compare safer and riskier plans.
Final Check
Use the confidence score as a guide, not as a blind command. Check the physical engine before carrying it. Confirm the small tank, hose count, and gauge direction. If the calculator shows two close matches, return to the house and search for missing notes. If computers are damaged, use the remaining clues and avoid equal pressure decoys.
Team Coordination
The table below the calculator gives sample cases. It is useful for testing. It also helps writers explain the tool to readers.
Big Oil becomes easier when evidence is organized. The correct engine is not guessed. It is filtered. Good teams call out clues clearly. One player reads notes. One player checks engines. Another guards the lab. Clear roles reduce mistakes. Better notes make faster escapes.
That rhythm saves minutes and keeps the final escape cleaner overall tonight.
FAQs
What does this calculator find?
It ranks Big Oil engines by matching gas, hydrogen hose count, and pressure direction. The highest confidence result is the best engine candidate.
Can I use it with missing clues?
Yes. Leave unknown clues blank. The tool still ranks candidates, but confidence will be lower because fewer clues are available.
Why is PSI converted to bar?
The computer clue may show PSI, while engine gauges are easier to judge in bar. The shortcut formula is PSI multiplied by 0.07.
What are equal pressure engines?
Equal pressure engines show around 400 bar. They are useful references, but the calculator marks them as decoy warnings for safer play.
What does confidence mean?
Confidence is the percentage of available clue points matched by an engine. More complete clues create a stronger and safer result.
Does payout match exact game rewards?
No. The payout section is an estimate. It helps compare loot, crew size, wrong attempts, and escape choices in one place.
When should I use the PDF option?
Use PDF export when you want a simple report for testing, publishing, or saving a clue example with ranked engine results.
Is this useful for team play?
Yes. One player can enter clues while others search, guard, or verify engines. Shared results reduce confusion and bad picks.
