Tuners pick a target lambda for each part of the map — around 0.85–0.90 (rich) at wide-open throttle for power and safety margin, near 1.00 for cruise and emissions — then convert to the AFR their wideband reads. Note the AFR number is fuel-specific (E85's stoichiometric AFR is ~9.8, not 14.7), so always tune in lambda when switching fuels.",
