Are you sure yours is not 2,6,5,4,3,1,8,7 or 7,2,6,5,4,3,1,8..

Seriously though they are the same order. Or were you joking?

Mine is 5.00000 4.00000 3.00000 1.00000 8.00000 7.00000 2.00000 6.00000
Is that right, and why do they change on some tunes?

it's used for misfire detection.... they just pick up the sequence at different starting points.
