LT1 PCM Tuning - Tips & Tricks for DIY Tuning!

Wide-Band/Narrow-Band O2 Sensors: two types of oxygen sensors, used for determing the air:fuel ratio (AFR) of an engine's combustion. Wide-band (WB) sensors are accurate along the entire spectrum (from very lean to very rich), while narrow-band (NB) sensors are only accurate along the narrow spectrum near stoichiometric AFR (14.7:1).

Air Fuel A/F Ratio Basics | Wideband vs Narrow O2 sensor

Lambda is scale that relates the air to fuel ratio of ANY fuel. 1.0 is stoic for every fuel. (the chemically perfect ratio of air to fuel for a complete burn). However, stoic is different for every fuel. Some fuels may need 14.7 lbs of air some may need 6 lbs of air for a complete burn. Lambda 1.0 is always the perfect ratio for the fuel in use.

Cylinder content: weight vs. pressure

Definition. Cylinders stored on the back of anesthesia machines are E cylinders. The height of an E cylinder is 24.9 inches, the diameter of the base is 4.38 inches, and the empty weight is 5.90 kg. Both air and oxygen are stored as compressed gasses, and therefore the volume can be calculated if the pressure in the cylinder is known.
