Timing - Ignition

[Robert J. Harris]

Subject: Ignition timing in conjunction with EFI

There appears to exist a number of sensors to build
an excellent self tuning EFI, yet the only sensor that
anyone talks about for ignition timing is a knock 
sensor that just tells me - oops too much - 
self destruct sequence initiated.

Factory curves and random published curves are all
that most without dynes have to work with.  Back in 
the bad old days, (pre computer) the killer secret for
street tuning was to advance the static initial timing
watching rpm and vacuum, until you got the max 
you could get and still start the engine, then put a
sping kit in adjust the mechanical until the total was
the same as what ever your guru of choice had
dicated.  Look for ping or knock, then put some
more in.  It works but had too much PFM (Pure F___ng
Majic) to be reliable for all engines.   Since then, many
bandaid seem to have appeared.

Since we now have computers, we should be able to
monitor something other than self destruct imminent and
tweak and peak the timing in conjunction with the fuel
to get optimum power and economy.

I truly hope that there are some good ideas out there.
