another timing question

What is the max timing advance on a 93 auto. the reason i'm asking is i have never heard my car ping, ever. i've owned it for about 10 years. i've run premium gas with a octane booster, and also 87( i know i know its a no no) in the car. it doesn't make a sound. i had to replace the dis in the past. i use a autozone replacement, i think it is a wells (not sure it's been a while). balancer doesn't wobble i'm going to get the timing light out and check the base timing with spout removed and installed. i guess what i'm think is maybe i've got a overly sensitive knock sensor. anyone know what the voltage the the computer sends to the dis? 0-5 or 1-5v or other? i guess some would think this is not a bad thing to not have pinging, but it makes me wonder. my 95 lx 4.6 is pretty bad at wot in the upper rpms on 87. my 99 silverado that also has knock sensors will ping sometimes usually have to really listen and it's just for a second. thanks.
