[Diy_efi] DIY-WB question

[bcroe at juno.com]

If your free air number looks good, your WB is giving the 
same readings as everybody elses.  Some dispute how 
well the free air point is aligned with the rest of the range, 
but many users have been quite successful in achieving 
a pretty good tune with it.  Far better than with just a 
rich/lean indicator.  There has been comment on 
transitional errors, which is like crossover distortion in 
an audio amp.  Since my own WB uses a different circuit, 
I can't comment on that.
