John,

Thanks for the input.  I do realize that the synch must be performed 
while running (like I said, the tool measures vacuum- not much vacuum 
when the motor's off). 

My idea was more along the lines of moving the battery, relays, ECU and 
other stuff on the airbox just over the side of the frame (on a table or 
something set up specifically for that purpose) while I did the synch.  
If that's not the procedure and the adjustment screws are accessible 
with the airbox on, so much the better.  That airbox is a pain in the 
ass to get back on anyway. 

You made the comment that you must also do an off-idle adjustment.  Is 
there usually a specific RPM at which this is done?

Thanks,


Garth
