i just noticed this when i was trying to time my car the other day. when i have the timing light on it i notice that when i bring up the RPM's the advance actually drops or goes down before it actually advances or goes up. any body have any idea what would be causing this?

just a thought guys, could it be the module that sits on the side of the distributor? i think that it does control the advancing of your ignition

the computer controls the spark timing throught the SPOUT circuit. unless you have a drivability concern, don't worry about it.

well with out the proper timing advance the car will NOT pull out of the corners, not hit higher rpm quickly and it wont acheive top rpm/speed quickly. If i'm not mistaken you also lose torque.

yes, but some computers will back timing out for a moment as the throttle opens. i don't remember why, i just remember reading/seeing it.
