here's a snippet

Lambda just means stoich for the fuel mixture.

gasoline stoich AFR = 14.7
Lambda = 1.0

AFR = 11.76
Lambda = 0.8

Lambda is basically just the multiplier to the AFR. From what I've read is we all use AFR to measure mixture but people in other countries like to use lambda. Some rather use lambda while others like to use AFRs. Hopefully you can actually change what the your unit displays(either lambda or AFR.)


I suppose this is like PSI and Bar with Turbo people
