[Diy_efi] Some problems with my FI conversion

[Jens Jensen]

Have been reading for some time - first time I have submitted a question
here.
 
I have a 62 IH Scout with a 4 cyl that I have put a GM TBI system on,
and I am running into a few problems.
 
As background, the harness is in - chip has a standard 350 bin on it
that I changed from 8 cyl to 4 that is a starting point for developing a
chip for this application.  I have a moates autoprom and tunerpro rt,
and I have just finished the install and am currently trying to get it
to run.
 
Did the key on checks and everything looks fine other than my knock
sensor is showing 0 and not 9 volts.
 
Some side notes - I am using a flamethrower coil.  Also - the
distributor is a GM - IH Holley merge - meaning a GM top on a Holley
housing.
 
I have logged a little data while it was at an idle.  I will attach it -
you can see the rpm's are at zero and not registering when I monitor
from TunerPro RT.  The RPM's did monitor during one idle, but have not
shown up again.
 
The problem I am running into is that the timing is jumping around
regardless of if I have the bypass plugged in or not - meaning that as
soon as I open the throttle the timing immediatly jumps to ~20, the
motor boggs down, I close the throttle, timing instantly returns to
zero, and then it has a huge backfire out of the exhaust.
 
I figure that either the EST is screwed or there is a problem with the
GM / Holley merge.  Before I tear into the distributor - is there any
reason that the timing would change even with the bypass disconnected?
