Plus or Minus?

[2002Z28SSConv]

If I want to advance the timing, "+" or "-"?

If I want to lean out the AD ratio, "+" or "-"?

Thanks

This doesn't make any difference but it says I should post it so...

Advance timing= +
Leaner A/F= - in the WOT fuel param., + in the injector slope param.

Thanks
