Laptop with MegaLogViewer HD

Postby Manu » Wed Nov 08, 2017 1:05 am

Hello Phil,

Using my last software CAN converter, I'm now able to log and melt any CAN system in a single file and open it with MegaLogViewer (and other formats too). I use MegaLogViewer HD.

Attached is a picture issue from a data acquisition on the Nürburgring for example. This is not the better example I can find because the track don't do a loop. But imagine that the track is a loop and that the customer do several laps.

The question is : is there a way to separate laps in MLV using, for example, a certain GPS position ?

Thanks,
Manu

Hmm, perhaps with Time and GPS?

Well, time is often what drivers fight for ;-)
This may not be an accurate data to input.

GPS location is what is often used in software as AIM RaceStudio. In this software you can trace a line between two points. This line must "cut" the track and define a virtual "start line". Then the software allow to "cut" the logs per lap.

This is what I'd like to do with MLV. Maybe there will be a possible Math formula that can do this ?

Thanks,
Manu

EDIT : I notice that there is no keyboard shortcut for "Save graph as PNG" in MLV. This function is only useable using the mouse, witch lead in "unselect" the current location in scatter plots. Can you please ad a keyboard shortcut for this function ?

Manually, you could put markers in the log at everytime the GPS/Track's finishline is crossed.
Then select the log in between the markers to show the Elapsed Time between those markers.

Programming this into the software, I think some calculations have to made/done for this to go automaticly.
Maybe a Circuit Lapcounter/timer plug-in for TS perhaps?

Something like:

Code: Select all
$startGPS = GPS at startingline
$currentGPS = GPS
IF currentGPS = startGPS AND speed > 40 (moving/racing)
THEN "write marker in log"


Then after the race, the software calculates Elapsed Times between all the markers.
Only problem might be that startingline GPS will not be the actual track's finishline.

This could help :D
