2.5 Timing Advance

When the rotor is exactly under the #1 post in the distibutor, how many degrees advance does the main crank read on a 2.5 liter engine?

This is the same question I asked yesterday but only slightly different wording. Thanks for all the feedback so far!

I'm not sure where your going with the question, but I can give you some info to help form a better one.

The timing is physically not adjustable, even though the housing has some minor movement when loose, it's recommended to keep it aligned. Distributor shaft alignment is done through a series of steps using TDC and alignment holes. Because of the gear driven set-up, there can actually be 16 positions, only 1 will work, and the plastic bit on the bottom makes it miserable to do.

The computer handles all timing/advance issues through pre-programed maps.

Typically, it'll run anywhere from 5 - 45 degs. At idle, you can expect around 12, it fluctuates alot. If you want an exact number, I can tell you tomorrow.
