VCDS: Grayed-out Measurement Values Explained

Hello, I've had my Hex-V2 for a few days now. Today, I wanted to test my KPower software, but my data blocks are grayed out in the MSG, which means I can't click on them.

"And if I create a log using the 'Advanced Measurement Data' function, specifically for speed and RPM, KPower doesn't recognize the log."

The vehicle is a 2014 Skoda Octavia RS 2.0 TDI.

Hi,

It is perfectly normal for newer engine control units to have the "Measured Values" button disabled in VCDS, because the corresponding diagnostic function is simply not supported.
From your engine control unit, just to make sure it's perfectly clear.

Therefore, click on "advanced measurements," then "group measurements" for better time resolution, and then select "RPM" and "speed" to log.

Have you read the instructions for KPower?

Please upload your log file here as an attachment. By the way, KOBD2Check can also generate the logs required for KPower.

Best regards, Rainer.

I have read and understood the instructions.

Okay, that makes sense. I just wasn't sure about the grouping part.

I've attached the log file. As I mentioned, when I try to import it like this, it doesn't find the "Time" column!

Hi,

VCDS changes the column labels just like I change my underwear. In your log, you completely omitted the unit for time (seconds) and instead inserted a useless space before "km/h". When you connect a different car, the log might look different again.

At some point, I got tired of dealing with that, so I programmed my own data acquisition system (KOBD2Check), which eliminates all that unnecessary fiddling.

It works across different manufacturers via OBD2, with a reasonable sampling rate for the measured values, and without pseudo-random column names in the log. It offers better temporal resolution and therefore a more accurate performance curve. In short: no headaches and no fiddling.

For the "Skoda Octavia RS Combi 2.0 TDI (184 hp)", I found a curb weight of 1487 kg online and simply added 100 kg for the driver and fuel. Of course, the actual weight should be entered in KPower during the measurement.
