Nope, I don't know what the difference is between computers but I had a 93, 
and now I have a 94.  Actually I still have the 93, and would love to be able 
to send back the 94.

No retard seen or detonation on top end pulls.  It just lays down if I put in 
more than 12 deg initial.  Have to crank initial timing waaay up to get 
detonation.  I don't think advance is quite right.  troy says I have 36 deg. 
availible in the box.  With 8 inital that is 44 total - too much right.  But 
part throtlle reaction and gas mileage seem to be directly related to timing. 
 What I have seen and used before indicates 12 initial 36-38 total is right 
for iron heads, but more initial and less total at 33-34 for al heads.

My scan tool will give real time TPS, MAP, BAR, RPM, Integrator, Blk lrn 
cell, Blk Lrn value, injector pulse width, timing retard, O2 values, just 
about everything except real time ignition advance - which I would really 
like.

Would a heated O2 sesor be advised?  Do they go direct to 12V continuous or 
is the heater modulated or timed.

Thanks for your help folks - Ryan.
