Today's update: I sorted out the sync signal from the cam. The firing order is 18726543, with the cam sync signal preceding cylinder 5.
Now when I retard timing on cylinder 1, it actually retards timing on cylinder 1, lol.
Today's cold start was more of a sag, even though I didn't make any changes to the cranking fuel or IAC. Today's change was to change the run/crank rpm number to 150 (from 400), and to have it start the fuel enrichment decay at 6 revolutions rather than 12.
I'll have another go at it tomorrow.
