Velocity AP Data Logs - Alternative Data Viewer
I recently purchased the VAP data logger kit and started reviewing logs from my car. I found the provided VAP viewing software a bit challenging when trying to zoom in on particular areas of interest. While looking for alternative viewers, I found a free .csv file viewer in the Microsoft store that works well - https://www.waveworks.dk/flow/. Here is a sample image of a VAP log from my car in the Flow viewer:
Some manipulation of the base csv file from VAP is required to work with Flow, but it is fairly easy to do. Here is the standard VAP file header as seen in Excel:
Here is the same file with a modified header to work with the Flow csv viewer:
The first seven rows need to be deleted and the Units row needs to be moved below the Channel Name row. Once the file header has been manipulated in Excel, the file will open correctly in the Flow app.
The flow app allows the user to scroll, zoom, add math channels, etc.
I would be interested to learn if others have found different tools to better analyze the VAP data files.

I mainly use the CSV and just freeze the upper frames, that way I can see the description of each column, sometimes I'll color a a few columns.
Looking in a graph form is hard to pinpoint some fine issues in things like lambda or charged pressure, which is generally why most tuners will want to export the file from a graph viewed program and search in the CSV.
However, when I need to use a graphview and can't be bothered to setup excel, I've used datazap for other dataloggers. It's a website that you load your file and it generates the graph. You will need to modify the header as you've done but allows the channels to be overlayed and you can disable/activate which ever is needed, trim, zoom..etc.
The graph viewer in our logger was more of an idea when you are running the vehicle and seeing the desired live channels, if you see something like timing correction skyrocketing on graph, you can get off the throttle versus trying to focus on the values in the left screen view. We added the playback option for fast viewing, but you would normally then go back to the CSV to pinpoint the values.
Nonetheless, here's a file I uploaded just now to datazap, which has the header removed. It's similar to Flow but doesn't require installing any program.
