    Question table 12878 "Torque Loss % vs, Spark Retard"

    What is the purpose of this setting and it's effects?

    Reason I ask is I see this zeroed in several performance tunes but doesn't it just tell the ECM what it's own torque reduction translation per spark pulled?

    For example it wants X torque so Y timing is removed to accomplish that.

    Am I way off in understanding what this table means/does?

    How would zeroing it out help, wouldn't you want to rather tell it that it's pulling a LOT of torque by removing a little timing..??

    I used to have random timing dips while cruising. It came from this table

    I zero'd it and no more crazy spark loss.

    I am still curious though is this is the best method, as I believe I have read that this is used during shifts in autos.
