Power grid timing logging

We have a grid with a lahey tdc indicator box sending the timing data to a rpm data logger.Does anybody know what settings affect the output signal for timing? It shows total timing but it never captures the timing as it retards through the run. Thanks.

 

Timing

The grid timing recording is fine. The leahy tdc timing indicator on the data logger is the problem. It worked fine with 8973. Leahy told me there is a grid setting that will make it function.it uses the gray tach wire from the msd box for rpm signal.for the 8973 it says tach trigger setting must be set to tach timing.i don't see that option on the grid.

 

Sync

The grid item I'm looking at is tach output sync. Could that effect the gray wire output to make the data logger happy?

 

Fixed

It works thanks!
