Alright, so I figured out that you really DO need to remove the resistor wire when upgrading to DSII.
The voltage drop was causing my GM module to flake out at low RPM. Duh.
Anyway, that allowed me to get my idle down to about 750 rpm. I went to set the advance again since I had the idle speed right, and I noticed that it was up around 35* initial. (Was at 10* initial before resistor wire removal).
So, problem is - I dropped the initial down to 10* again and everything is fine, but...
when I rev - it shows my mech advance coming in and RETARDING the timing 10*. Just about 2 hours earlier (before removing the resistor wire) I had double-checked it and it was working exactly as it should.
So what the hell? How can my spark timing retard w/ RPM ? I only have mechanical + initial, no vac. Mech is limited to 10* via welding the plate in the dist.
Anyone seen this before or am I just seeing things?
