ION knock detection

[Raymond C Drouillard]

Are you planning on selling PC boards?  If so, put me down for at least
one.  If necessary, I can put in a little "seed money" to get the first
batch made.

When you design the boards, you might want to consider adding some
optional circuitry.  For instance, I plan on taking the 0-5V output from
EGOR and running it through a couple of op-amps to get a 0-1V output that
spans only the enrichment levels that I'll be using.  The Holley 4Di
computer has a table that allows the user to specify an O2 voltage set
point for various operating conditions.  I plan on running it lean at
cruise and rich at WOT.  The whole idea is a joke with a standard sensor,
but should work fine with EGOR.  I'll hook the 0-5V output to a dash
gauge just for kicks.

Are you planning on using HV diodes for ION, or are you going to put a
bias voltage at the low voltage end of the coil?
