Cupra 280, there should be a crude way of doing it by logging the "speed" of the output shaft for an output shaft of an Automatic transmission / DSG
...or the ABS wheel speed sensors, then compare this to the time in the *.*CSV logs that are taken. It is a cumbersome way of doing it, but it can be done.
I'm convinced that you do this sort of thing in Excel all the time with your other logs.
Since everyone has ABS, then it is easier to use that. I'll look up the channel number that the OP would have to log from a standing start (assuming no wheel-spin). In VCDS, it is the DSG module that is used to take the measurement, but I think it gets its speed input from the ABS

Matthew as always you are correct,
On my car there are several speed options (Left Front, Rear / Right Front, Rear / Vehicle Speed)
You also have gps time along with some other time items in Live Data so I guess that you could very easily do this.
However I suspect the op just wants a simple option to do this.

OK Had a bit of spare time this afternoon and have done the crude workout. 060.xlsx (39.05 KB)
As you can see in this bit of my chart, my start speed was 0.5 (label says KPH but i think its MPH as that is what it showed when I was looking at the screen and also the values I saw when I was driving. the GPS Start time was 15:46:00 and at 15:46:07 (very slow 7 seconds later) I was doing 60.1 MPH
i did this using the Information Control unit (please note Vehicle speed is shown on lots of control units but I certainly found one that does not work on my car anyway)
The Parameters were GPS time : Hours, GPS time : Minutes, GPS time : Seconds, Vehicle speed : KM/H (But feels like it defaults to your car settings (mph on mine), Engine Speed : Value 1 - RPM

You did some very good work here, and your spreadsheet makes sense. The one thing that I see is that it appears as though your car only hit 60 MPH after you shifted into 3rd gear like the car automatically upshifted at the redline? Did you have much wheel-spin when you launched the car? If you could somehow magically replace the 2nd gear with a longer ratio, then you could hit 60 MPH while staying in 2nd gear and not waste "boost" and drop in RPM during the gear change. The other approach could be looked at from increasing mid-torque using a bigger turbo such as moving from a stock K03 to a K04-64 unit to quickly get to 3rd gear in a stock transmission, but have the ability to use 3rd gear to achieve 60 MPH more quickly. Edit: your results are not slow by the way. I've recorded 5.6 seconds using VCDS with a good track surface on soft compound tires. Your spreadsheet doesn't show any wheel-spin, so traction doesn't appear to be an issue for you. I don't mean to detract from the original meaning of your post, but your spreadsheet has meaning by which to benchmark straight-line performance for the 1/4 mile. Was this log done with traction-control / ESP/ ASR turned off and in manual or sport mode (to ensure you really maximise the factory redline)? As it relates to the original post, I believe the OBDeleven team can create an "alarm" that resets when the vehicle speed is "0" , starts a timer when the speed is over "0" (such as 0.5 MPH) and then alarms when the 60 MPH is reached (performing a calculated time difference such as what you did in your spreadsheet) and displaying the result on screen.

Matthew lots of questions to answer. Firstly I am having a stage three upgrade done to my engine and gearbox, along with full engine / gearbox mounts and power will be a little more exciting. I also have some light wheels with better rubber so that will all help.
Did not get much wheelspin but to be fair i was not pushing it hard or using launch control, just wanted to make sure i could use the software to do the work. The other thing at the time I was not in Cupra Mode (which makes better throttle response and gear changes (it holds 2nd to the red line) much more aggressive.
I am off to vag tuner live on the 8th July and have some track time booked, hopefully the maps will be done so I can see how well she really goes. I am also getting some new suspension, not sure if I am going to lower it yet but I can adjust the dampers from my phone so looking forward to that.
I do plan to do some more runs before the upgrade so i can have a pre and post time map. In stock the car should do 0 - 60 in 5.4 and at stage 1 (where I am now) should be around 4.2 but to be fair this car is not about 0 - 60 its very much a track machine and fast road car doing well in the 30 - 130 (which revo quote on 4wd as 11.17)
Upshift issue was because I did not put the gearbox in sports mode and turn off all the saftey features..
Last point in the new map they have increased the red line and as with all revo's they have removed the speed limit so looking forward to some fast track time.
Thanks for the feedback
Oh one last thing here is the fuel feedback from the car after my testing
