Over-clocking Stock Ignition

[driller]

4. Can the EDIS (Gen 1) or ECM (GEN 2) provide precise enough timing? (<1 degree error @ 6000rpms = >18,000 Hz...by today's standards, no problem. Back in the mid 90's, maybe not.)

That's my suspicion as well.

I can set up a remote desktop connection with you, and I can "look over your shoulder" at all the porn you've downloaded (joking smile)

LOL, you IT guys always want a remote desktop connection.

I started losing spark around 7300 rpms on the 1994.

Thanks, I'm nowhere near that number from what I know that but that's interesting to know.

Spark Source only tells you what spark table the PCM is running in at the time.
Will have no effect on high RPM operation other than to tell you if your running on the borderline table or the base table or some other spark table.

Max spark limit is..just what it says...its the max spark allowed by the PCM.
Again wont have any bearing on higher RPMS or not, it's just a "set value".

Those are obd2 functions, not EEC-IV
obd2 uses max allowed
eec 4 uses "wot spark", and is a much simpler easier to understand process.
WOT spark is WOT spark.

Oops...I forgot he was running OBD1, which I know little about.
