Is it reading half of what you expect or only slightly low. Have you played with the DIP switches and set it to 8 cyl or 6 cyl mode.

Feeding from Megajolt usually works OK.

Feeding from the EDIS can be temperamental.

Feeding from a coil pack required 2 diodes and a Zener diode.

i have a similar problem on the puma system. has anyone got a diagram of the best way of wiring the tacho please. ooh i hate electrickery.
