When the datalogit is linked to the pfc can you still see what the commander usually displays or does the screen go blank,thanks Roy.

 

I had the problem i believe you are describing. When i daisy chained the PFC to the Datalogit and then the Datalogit to the Commander, I thought that the Commander was then disabled.

Push the connector in harder as the commander does work while the datalogit is connected.

 

The commander still works fine. However when you're datalogging the commander doesn't get updated very often (every 10 seconds maybe) so ti may seem like it stops responding.. Once you stop logging it returns to normal.
