Ignition timing is not adjustable except through a chip or the learned memory. The learned memory is dumped during an extended power loss.


Pinging is usually due to a lack of EGR, running too hot, or a lean mixture on acceleration. Sometimes crossfiring plug wires cause an inconsistent knock. A harder knock is usually mechanical.




That is a good list of possible things that can contribute to ping. I wish to add tow things. Carbon build up in the cylinders and fuel quality.

Before doing anything else, try other brands of 87 octane fuel. You may find that it is nothing more than sub-standard fuel.

Excessive carbon build up in the cylinders can contribut to ping in at least three ways. Added compression from the extra material in the combustion chambers, hot spots from the carbon contribution to pre ignition, and a lean mixture from restricted injectors (as well as restricted valves). A really good injector cleaner added to the tank may do wonders for your performance. Even more help would come from doing a decarbon processive. Berryman B12 seems to be the product of choice for decarboning. If you look around here with a search you should find the instructions on how to do this.
