1999 Accord 30-6051 Tach is wrong

I have a 99 accord, 30-6051 with v6 and 6 speed with a 2001 harness.  The tach in tuner is reading higher than the dash tach.  How do I adjust this.  Its 250 off at idle and looks to be 1000 or more at 4000.  Is there a know issue with this setup. I believe the tuner value is correct

Hey Brad,

Hey Brad,

The 30-6051 ecu was designed to function with the 96-00 Civic cluster (4-pulse per rev). The tacho output may be re-configured on the Tacho-speedo tab of the AEM tuner software.

If you hold the rpm in AEMtuner at 2000 rpm what does your dash tacho indicate?

So I posted my original

So I posted my original question quite some time ago but had some other issues come up that I had to weed out.  How do I adjust the tacho output.  That is definitely the problem.
