Engine Masters - Season 8 - Eps 20: A Study in O2 Sensors and AFR Readings
Standalone air/fuel ratio gauges have changed the game when it comes to tuning carbureted engines, with a world of possibilities and pitfalls when using them. We start by comparing five off-the-shelf units, then move on to showing how things like placement, air leaks and even dead cylinders can affect your readings, your tuning decisions, and ultimately your power levels.
