), I can't really start it and test. But I made two assumptions that I wanted to verify.1) I read that the HEI runs in a 'limp-home' 10* advance mode if it's not getting an ECU signal. So, for the immediate future, I figured I could leave my distributor mech & vac advance enabled, but just retard the timing 10*. This should work until MS-II (at which point I'll lock down the vac & mech advance and hook up the advance control), right? Or am I overlooking something?
2) For the 'start' override -- There's no 'run but not start' wire under my hood - there are some under the dash, but it occured to me that it would be easier to set up the relay such that the output is normally connected to the 5v vref connection, then disconnects when the relay is activated by the starter. The vref turns off when the ms turns off, so it doesn't have to be disconnected when the key is off. Also, just for good measure, I went ahead and grounded the normally open contact, so instead of releasing it to ground on start, it actually grounds it. This, too, should work, I think... Anyone see any reason why it won't?
Now just gotta find meself an IAC
