Hi Cosworth, 

I have seen a Delta Time channel in some Workbooks, how do I get one?
Also, can I compare data from the same session, i.e. lap 3 and lap 5 against each other?

Thanks, 

Ruprecht

To compare the times, use the attached math and import through the Pi Maths Import in Toolbox.



To compare from lap to lap in same outing, load in the dataset to your task twice.

You can also shortcut this by using standard windows copy and paste commands to copy the dataset in the task window and pasting in the same task.

Thanks for sharing. This worked like a charm. For future reference, this is exactly what I did:

1. Download the Compare_Time.zip file and unpack on local disk
2. In PI Toolbox click Tools -> Pi Math -> Import
3. Follow the wizard and select the Pi Math file you unpacked
4. Press Alt + 2 to open the list of available channels. You should now see a new channel called Compare Time with a plus icon next to it (indicating that it is a calculated value).
5. In any worksheet, click Insert -> Display -> Time/Distance Chart
6. Press Alt + 2 to bring up the list of channels and select Compare Time
7. Press Alt + 1 and add two outings (or two different laps from the same outing if you like).

You should now have a graph with the delta time between two lap times. The flat line represents the fastest lap, and the other is the delta (difference).

Hi,

I try to use the functions CT Derivative and Win/Lose channel with PI Toolbox but unsuccessfully because I make a mistake probably somewhere.
Do you have a procedure available for these two functions in order to help me?

Thanks in advance for your help.

Hi,

Further to your request you'll find below the math channel.

Good luck

Thank you for this as I'm surprised it's not an out of the box channel.  For some reason the graph I get is very jagged and appears to only be calculating the difference on approximately 1 sec intervals even though I've set it to 100 Hz which is the same as the Elapsed Lap Time channel.  Does anyone know how to get this more precise?  I'm using data from the PDR if that matters.  Thanks.

I answered my own question.  I had to map The Distance channel to "Recorded Event Odometer" instead of "Odometer Distance" to get more fine grained graph.
