Over the next few weeks, we will break down practical tuning decisions that separate a good setup from a consistent winner. We will cover metering architecture, emulsion choices, airflow transitions, and trackside diagnostics for gas and alcohol combinations.
First, we focus on the foundation. Before you reach for jets, confirm the metering layout and signal path. Your idle and transition circuits set the tone for everything that follows. BLP billet metering blocks provide tuners with control over emulsion, idle feed, and power valve restrictions, allowing the fuel curve to match the engine rather than forcing a generic pattern. The goal is a clean start, stable idle, smooth handoff into the primary circuit, and efficient wide-open fuel delivery at your target BSFC.
Next week in this series, we will demonstrate how emulsion changes affect transition quality and top-end power, providing sensible starting points for common gas and alcohol builds.
