Mechanic & Jetting

Mechanic & Jetting

12+ engine variants: X30 Jr/Sr, Parilla Leopard, IAME OK Junior, IAME OK, Rotax 125 MAX, and more. Deterministic smart-rec + LLM in-range tweaks.

Jetting calculators are usually one of two things: a static rules table from a forum, or a calculator that takes air density and spits out a needle. Both leave the actual work to you.

We start with the deterministic safe-range for your engine + the current air, then add an LLM layer that knows your history — "you've trimmed the main needle a quarter every time the track temp drops below 18°C this month; recommend doing it again now". Setup and jetting recommendations cross-reference: if the setup change implies a different load on the engine, jetting moves with it.
