Re: Nutter question
This is deja vu all over again (you'll see what I mean), but I'll answer your question here, also. Timing should be 9 degrees (+/- 2) at 1600 RPM. That is with the vacuum advance disconnected and vacuum line plugged. Regarding the nutter bypass, I think you're right--the ability to retard your timing in certain situations (all of which I'm not sure of--they're encoded in the computer's little brain) is eliminated, but more than anything, it meant that I could remove all of those wires and hoses from the engine compartment, making maintenance MUCH easier. I've also increased my timing to 10-degrees at IDLE for a lot more "kick" without the worries of the computer trying to "correct" it (does require premium fuel, 89 octane is good for 8-degrees in my experience).
