No trailing spark but got rpm! Help!

Hi!

Ive been driving my rx7 for a while now without really knowing if the ignition is correct so i started fiddeling with it..
Its a 13bRE with s4 CAS and jspec s4 pullies.. LT8..

I got no trailing spark (checked with a plug hooked to the wire while running the engine etc) i got RPM signal to my stock gauge but when i rev it past 4-5k i loose the signal but it comes back when im under 4-5k rpm..
My wires and plugs are all new.. the trailing coil has worked befor!

Also, are you using the leading or trailing for checking for correct ign?

you should be checking timing with leading plug 1. check your CAS wiring connections, that could cause you to have a bad signal. or you might have a bad CAS .and double check your grounds.
