To the OP.. using lambda is nice, but you have to remember any AFR number for a specific fuel has a lambda number equivalent, so they are just different ways of expressing lambda.
If someone says they tune E85 to 12:1 gasoline AFR, it may not be sematically correct, but it gets the point across just fine. What they should say is the lambda equivalent of 12:1 gasoline afr. But most widebands read in gas afr, most people are used to the numbers, so people use it, and it works just fine.

. afr is just an equation. how it is read is, LAMBDA x "whatever afr you want" in the case of gasoline its 14.7. hence people tune stoich at 14.7 afr's. 1 lambda will ALWAYS be stoich in ANY fuel.it would be like saying HP is more important that torque... or that you get torque from HP

Right click save as.
Like that, no detcans needed, didn't happen to be as significant change as in this soundbite, but similar noise.

The point I was making is it doesn't matter whether you use AFR or lambda... because as long as you know what fuel you are talking about when quoting AFR, it's easy to know what lambda. For example everyone knows gas AFR of 12:1 is about .8 lambda. Who cares which term you use. They both express the same thing.
If you want to be pedantic, yes you should use lambda for any situation where you are using a mix of two different fuels. But it doesn't really matter. It's a non-issue.

Audible knock, like knock that cannot be ignored

What are you talking about? What exactly did I say that was "wrong"?
