Guys, I need help to understand HP tuners, Just starting to learn how to.
I need to know if my wide band is good, it reads 12.80 is that ok or should I lean it out. And My friend runs 38 degrees on his timing he has old school motor. My HP tuner scanner said I am only at 29 degrees of timing, That's at max and low is about 25 degrees> is this good or bad and can someone tell me why there is a differents in timing from old school to new. What window do I open to edit my air mixture and to change my timing. Please walk me threw the points on how to change both.

Thank you for looking. Ken

I wouldn't worry about your friends timing. I cant tell you if 12.8 is where your car likes to be without knowing your mods or seeing your tune. What is your commanded AFR? To check what your commanding go to >Engine>Fuel>Power Enrichment> PE vs Eq ratio. As far as your timing goes >Engine>Spark> High octane. Hope this helps

Even 29 degrees of timing is a lot for an LS engine.
Here is a very informative thread on the subject:

In short old SBC have optimum timing in the mid 30s while LS engines (typically) have optimal timing in the mid 20s.
