It does not work when starting and flits about for a while and than settles down after a few k's but is getting worse.
I have spoken to Haltec as I have an E6X and a tach adapter and was told that I can almost certainly rule out the EMS and adapter and that some Cordias had this problem that a thump om the instrument panel seemed to fix it.
I have no clue as to electronics so any help/constructive advise would be appreciated.
