the hondata adjust timing for advance or retard based on the mapping ( if I read the manuals correctly ) so I don't think it would be wise to run the aem adjustable cam gears, set to anything but 0. since the gears would be a few degrees off what the ecu thinks it is. I am in riverview so brandon honda will be it, and does the o-ring on the dizzy need to be replaced whenever you remove it ( like most gaskets ) or is it good to go as long as it looks in good shape? thanks
