I have a question...

This maybe be retarded but...

How does/could timing effect A:F readings on a wideband?

misfires/breakup - real rich? would it even show up?
too advanced -
too retarded -

The way my mind works, I can't see how it doesn't effect the reading. Igniting too early of course blows seals, but if it's too late is it possible all the fuel doesn't ignite?

Is there a point where retarding the timing too much is harmful?

TIA, someone enlighten me or give me a good swift kick in the pants.

 

Might want to dig through the single turbo forum - I know there's been a number of posts on the topic, with some really good ones on timing split.

Many times advanced timing doesn't show on a wideband - that's where EGT's come in handy .
