it shouldn't change barely at all after you put the spout back in. the spout simply allows the CPU to change the timing for the RPM curve, when you remove it your setting the base timing. if its really changing that much, i'd say your setting it wrong.
totally wrong.. in the stock computer, the idle advance is around 28° give or take.. when you pull the spout out it locks timing at 10°. when you put t back in, its supposed to jump.... thats what the electronic advance does.

right, but the computer wont advance the timing or retard it with the spout out. it doesnt really lock it anywhere.

uhh no, set your base timing where you want it, like 10-12 degrees BTDC, then when u plug it back in, it will stay there, and wont go below it.
Negative ghost rider........
Engine idling +
SPOUT off = Initial mechanical seting
SPOUT connected = 20° - 26° and varying
if it stays at the initial SPOUT connected = there are problems in the ECM/wiring/TFI/......
