Cheat sheets

5 one-page reference cards, built to be printed and pinned above a workbench. Each one prints clean on a single sheet — no header, no navigation, just the numbers.

AFR & lambda targets

Lambda targets do not move when the fuel does — that is why they are the safer number to tune to.

Injector flow & hp support

Flow converts with one factor — cc/min ÷ 10.5 = lb/hr for petrol.

Alignment ballparks

Your car's factory specification wins over any table — suspension geometry differs too much for universal numbers.

Bolt pattern reference

Patterns cluster dangerously close together — 5×112 and 5×114.3 are 2.3 mm apart and a wheel will feel like it fits when it does not.

Air density & power loss

Every number below comes from the same formula as the density-altitude calculator, so a printed sheet and the tool can never disagree.

Why these print properly

The site already had print styles that drop the header, footer and navigation and flip everything to light. These sheets are laid out to use that: one page, tables that will not split across a page break, and the source calculator linked at the bottom in case you want to run your own numbers instead of reading off a row.

Where a sheet's figures exist in a calculator, they are generated from that calculator's own formula rather than typed in — so a card on your wall cannot quietly disagree with the tool on the site.
