lambda output to a/f ratio

[jel]

hello

If i save a logfile, the only data i get is lambda output.
Do i have to convert this to a/f ratio using exel

Also i like to know how i can add rmp output

Thanks Jel

I dont know how I missed this one, sorry about that.

We use lambda exclusively because it is a true reading and is fuel neutral, AFR is a function of lambda (for gasoline 14.7 times Lambda).

As for input this is kind of explained here: http://www.vems.hu/wiki/index.php?page=AfreshTiny under the RPM and wheelspeed input section
