CDI/8 problem

[TPMracing]

hey guys woundering if anyone else has been having some problems with CDI8's for our application we need atleast a 6 channel ignition system and the problem is we have had it burning out coils to start with sent it back they replaced the mother board and now it has shut two cylinders down whilst at full speed

prior to this we had no problems for the 4 years we ran the sytem

i would put the first one that was burning the coils out to old age and had been shoock to pieces after 4 years running but this second one has done about 3 hours engine running time and its gone cheers
