Adaptive Spark on Vortec PCM?

[N0DIH]

Anyone know specifically what the "PE Spark Learning" does? And why is it not recommended?

"Specifies if PE Spark learning is active at WOT.
Setting to "YES" will turn on Spark adaptive learning at WOT.

Usually not recommended to change this perameter.

Only the following values may be entered into this table:
- No
- Yes"

I honestly leave it on, and have had no ill effects. I have NOT attempted to experiement and verify that it does something. I run 87 octane and have NO ping issues. I run a fair amount of extra timing with mine. My best is 15.1 mpg on a 454 with 3.73's and a loaded Suburban K2500.
