Scott,

"Base timing" has to do with the orientation of the internal parts = of the=20 P-Mag. If you wanted to use it operationally, you would have to = mount the=20 unit at a precise angle in the mag mounting hole. Others on the = LML have=20 reported some degree of difficulty doing this. So, the folks at E-Mag = devised a=20 quick setup method where you can mount the unit in any orientation and = then=20 "program" that position as TDC (with the flywheel so positioned).

This option only became recently available with firmware version 16 = so=20 earlier versions would not have the potential problem and if you do have = the=20 later version you should contact E-Mag for the fix.
