Discussion and questions related to the course EFI Tuning Fundamentals
do you have the ratio for AVgas fuel. ?... used from the normal single engine airplanes...
14.7; Avgas is just a leaded fuel.
Keep in mind that the lead WILL kill your lambda sensor pretty quickly.
Actually Avgas isn't just a leaded fuel. There are various grades and designations for avgas.
e.g. 100/130 is leaded (the lack of letters after the octane rating tells you this)
100LL is low lead
100UL is unleaded.
After a quick search, Avgas is available only at 2 places in Mozambique (Maputo FQMA and Villanculous FQVL) and distributed by BP who (as far as I know) only offer 100LL, so I doubt Silvio have a choice.
Anyway, UL or LL, the stoichiometric ratio remain 14.7:1.
