I am messing around with the fuel in the buick and would like to determine what the IGN guage is actually showing. It is supposed to be timing but I doubt 40 advanced or retarded is possible (thats where I seem to be at highway) premium it goes to about 38 which is really terrible or really good.

When I start the car on a cold day and shift into gear it moves to -3 while the engine is running slow.

So what is a good IGN value? As low as possible? As high as possible?
Is it REALLY showing an Advance of 40 and is that a good thing.

Just not sure how to guage what is ideal for that number.

Cheers
Ryan
