APEXI delay flameout can display voltage, oxygen content [O2] and air-fuel ratio [A/f] in addition to the general delay flameout function. When matched with S-AFC or V-AfC, the A/f data can be displayed Adjust to get the best fuel supply curve. The child and mother are separated, and the ultra-pocket volume can be placed anywhere.
