timing I've set both my main and extended spark advance tables as well as setting my coolant correction is at 0. Why is my scanner showing me different timing values than the ones i set? What is changing them? Is there different variables i don't know about?

What system are you running?
Depending on the system you may have other things affecting the advance, like the IAT, knock retard, PE timing table, or maybe you didn't really zero out your ECT vs spark table like you thought. On older TPI systems the mask value is 20 instead of actually zero.
What exactly have you got and what is the difference you're seeing?

Are you talking timing only at idle, or everywhere? and how much is it off by?
