what type of symptoms will i see if my ecu pulls timing? i hear that no rear o2/bad rear o2 sensor pulls timing, what exactly does that mean.

Means the ECU is retarding timing. you will notice a slight loss in power. I have not heard the rear o2 will result in timing map change.

i heard of some dyno tests supposedly proving that no rear o2 sensor will pull timing, but i dont know so i was just curious.

ummm.. do a search. its been discussed and agreed upon by several that not having the rear o2 will pull timing.

Bill Hahn even agrees.

youll just loose some power if the ECU is retarding your timing.
