Hi,

Can anyone enlighten me on which option I click into in VCDS (rosstech) to time a 3000rpm-8000rpm run in 3rd gear?

Also, I tried the acceleration test, I hit start and set off but it doesn't register anything, is there something I might be doing wrong? The syste, says it's connected etc.

Help would be much appreciated!
Thanks

you dont need VCDS for this although i,m sure you could use it , use the lap timer in the dash that will give you a good enough idea

No idea on your question but Dynolicious app on the iphones does all the timings...... If that helps

Just log RPM and click the turbo button. Go about 2000 rpm and put your foot down until you hit the rev limit. Save the log and look at the time between 3000-8000.

The lap timer method is way to inaccurate let alone the validity of this test finding problems to start with.

If you've got Vagcom, log timing and correction, this will give you a better idea of potential problems.

Good luck.

and post your results here, I wil do the same, for comparison !

I'll do the logging at the weekend including timing and correction. Temps will be about 12c here at the weekend so nice and cool for accurate results

If you log intake temp also that would be handy.

Here is mine (shortly after my new engine was run in, so this would be the closest representation of how the logs would have looked like from a brand new RS4)
