Engine Log Help

[Mario]

When I am looking at an engine log there is a Vertical red line at consistent intervals. What does this represent? Thanks!

To the best of my recollection, those are time gaps........

It might help if you were to post the actual log!

It shows up as a Mark in the log file But I don't know how or why it is triggered, I can't find anything in the manual that references it either.

Hitting the space bar during logging gives the red line...

Yes, this is the same type of Mark you would get hitting the space bar. but it is at very specific intervals. So my though is that this is when the ECU is starting the Sequential cycle over and the line is a representation.

Phil, can you confirm that for me?

Yes, the red lines are MARKs.
In a normal log there is a MARK if you hit the space bar or an event like going offline occurs.

With the high speed logs like the engine log, the data is not read in a steady streaming fashion like a normal data log. In this case The Firmware writes the raw data to a page of RAM, then when the page is full notifies TS that the page is ready to read. TS reads that page, then the firmware starts logging again.
So you will end up with chunks of data with pauses between them. To make it easier to see where these data gaps are, there is a MARK. So you can know that you shouldn't expect the data have proper continuity across the red line.

Thank you for the clarification Phil, that is just what I was looking for!
