Hi Mark;

Well, the 3800 and high rpm were classic CAS signal breakup hints.
If the shielding/grounding was scoped and OK.
Is the rx8 pickup a hall-effect type with the weird 36? toothed with 3 
gaps -> A 36-2-2-2 wheel?
Next guess would be a loose pickup, air gap or something as simple as 
metal shavings on the pickup.
Cheers
Cary
