Add lambda <-> AFR conversion #950

Open brentpicasso opened 7 years ago

Looks like we could use a lambda to AFR conversion, and vice-versa.

This may be a documentation issue rather than a formula conversion.

It depends on the fuel type used: http://www.partssa.com/downloads/2040198/Conversion+Table+lambda+air+fuel+ratio.pdf https://forum.efilive.com/showthread.php?21599-How-do-I-convert-Lambda-to-AFR

For gasoline, AFR can be calculated from Lambda by doing the formula: (stoic is 14.68) Lambda 14.68 or Lambda (1/14.68)
