Hi! Paul
Don't ask me why or what but it sounds like you have the tacho connected
to the wrong place which doubles the speed recorded.
I have read other postings on this.

Subject: Europa-List: Rotax tacho
Some time ago I posted a query about the nonsense readings of our Rotax
tacho.
Have now got the TCU rpm output to compare. When idle (TCU about
1500rpm) rotax
tacho not too far off (about 1700). When engine running at 2500
according to the
TCU Rotax tach reads >4500! Any thoughts as to if this suggests a duff
tach or
a duff signal from the coils?

Paul
