For years, sbf's have produced the most power with
a total advance of 36 degrees + or - a bit
While that is proven for WOT
What about cruising around town
Optimum values can go as high as mid 40's
This goes to show why you will never find that ..........
"Perfect Dizzy Setting" you seek
How does Ford obtain the best of both worlds simultaneously
Spark Table in the pcm
It uses Load and RPM to determine best spark for cruise and wot
Lets use WOT for an example
It uses basically the value of 10 at the dizzy
and
It adds 16 more for a total of 26 at max load and max rpm
Why do we get more power when we dizzy twist
Remember the little statement about 36 degrees
Here is where the rub comes in with dizzy twisting
We spark it up for max power

and
it works
We then quickly see the ping thing
because the dizzy twist thing
has thrown off the optimum range for cruise
As with a lot the things
It depends
or
One good thing can hose up another
Its all about ......... Compromise
and
Knowledge gives one the ability to Compromise the least
Hope I splained it good enough to make sense
if not
ask more and maybe others can ............

clean up my mess
