J,
Regarding static advance, yes it works the same way as a stock distributor. Given that my programmed curve as approx. 19 deg (see table above) at 1500 RPM, and I want 25 deg BTDC at 1500 RPM when shooting the timing light, you are effectively turning the distributor by 6 deg. I suppose you can bump the whole curve by 6 deg and eliminate the static setting.
Concerning switching programs, I wired up a switch which I located on the firewall where I could I could use to toggle between program 1and 2. The 123 instructions are not bad, and you use the same power source as used to power the distributor. Since I did not want to hard wire the distributor to the car, I wired up a multiple-prong plug held by a small box so disconnecting the distributor is a snap. Picked up everything I needed to do this, including the switch, at RadioShack for under $10.
