My car has the pinging noise to quite a severe extent.
After about 3000k's travelled in the car the pinging occure a couple of times and only very feintly.
After installation of a header-back exhaust system, perrin CAI and an ecutek tune the pinging became a hell of a lot worse. Very noticeable inside and outside of the car in nearly every gear under load from 3k-5k rpm. Particularly noticeable under WOT and through 2nd to 4th gears.
I have spoken to my workshop foreman, the exhaust shop and the ecutek tuners that wrote my tune.
Suspicions are it is something related to mechanical switching between the 2 injection modes.
I have flashed the factory ECU tune back to the car and the pinging whilst still present is now less noticable and only happens for a second around 4K rpm in most gears under the same load conditions.
I have sent log files and video clips to the tuners to investigate further and see if it something that can be tuned out.
Will follow up with updates as i get them.
