[Diy_efi] Bernd: UEGO sensor question

[Perry Harrington]

Bernd,

Am I dense, or does the UEGO require a pullup on the Vs line?  I see in the
DIYWB they have a 2v pullup.

If so that explains your comments and why I was not getting it.  The Vs
doesn't produce voltage, it's resistance changes in response to oxygen content.
It's impedance lowers as it leans and gets higher when it richens.  With
the final impedance being < 100k.

Please set me straight.

Thanks,

--Perry

BTW, what's the story with the DDL?  I notice you have schematics but no
values, etc.  Is it a product you made that you posted some info about in
order to educate people?
