730/727

[Bruce Plecan]

What I'd do is,  Use your hall sensor to trigger an oem gm ignition module.
Use the module to run a aftermarket CD, or Jacobs unit.

Using the CD takes the load off of the module so a min heat sink is needed.
The input to the ignition module just needs to fire a LED thru a 1K
resistor.
Watch the polarity on the module input.  It has a slight current/volatge
applied to the reluctor.

There is a correction in the code for advance per 1,000 rpm for the increase
in timing when using a reluctor type sensor (A/C generator).  Not absolutely
nessecary to change that, just remember your timing table won't be
reflecting that.

| I have a similar question.  I plan on using the 730 on a project of
| mine but would like to use the stock distributor.  The dis has a hall
| setup without any advance.  How would I go about making it work
| with the computer so it runs the spark timming.  I was thinking
| about using some transistors for switching .
