Is it a 'go as high as you canw/o pinging' type of thing or is 14* the perfect setting. I currently have mine at 17* and it doesn't ping but I'm running 93 octane. Can I get away with running 87 or 89 cause 93 is expensive?
Thanks
Thanks
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
