Port tach not matching Conext

[Bennie]

I kept looking at my RPM read out on my Conext and realized that it's not matching my tachometer dials. The port side is off the most. The tach keeps showing 100 - 150 rpms MORE than the Conext system. Which one is right?

Any fix?

I have the same issue, I just figured one is right and the other is wrong...sounds simple but its a little irritating.

Any ideas on this? I'm lost

One is digitial, one is analog....so they won't match identically....my guess is the needle on the analog gauge was attached slightly off....

I find my self only looking at the connext screen and the engines are in harmony when the rpm in even on that

ok - thanks for the replies. Didn't know if something was off.
