Speedometer Scaling



In the $EE PCM from my '94 Vette there are three values that contribute to
the speedometer scaling.  With a 3.08 rear end and a 285-40ZR17 tire, they
are:

Speedometer Scaler:  25
Speedometer Scaler Fraction: .984
Scan Tool Speedometer Scaler: 41.5

(These number are after massaging into some unknown units by TunerCat
software).   Could someone summarize what these numbers mean in the real
world, and how one would tweak them for a gear change to, say, 3.45:1?

Thanks for any info!
