Alfa Elite Rally Computer on 4kq?

[Jim Dupree]

I don't have any experience with the Alpha Elite Rally
Computer but the manual describes a "Hall Effect"
sensor used for wheel speed. The signal for a "Hall
effect" sensor is significantly different from the
signal you will get for the magnetic reluctance type
sensor the Audi has in the speedo head for the cruise
control. I have mounted several "Wheel Speed" sensor
to the side of the trans and mounted the magnets to
the inner CV joint. Clean the outside CV joint and a
drop of super glue for each magnet followed by a round
of strapping tape. A sheet metal bracket to hold the
sensor can be made to mount under a couple of the side
flange bolts for the trans case or any of several
other existing bolts or bolt holes.
Good Luck on the rally
Jim
