Fwd: Re: [A4] Need for Premium Gas in 1.8T quattro?

[Robert Myers]

You can feel the knock sensor cutting back the timing.  There is no 
missing it.  It feels as if some little man were sitting in there 
with his finger on a switch and when he detects a single ping he 
shuts the switch off and you loose a major portion of your 
power.  Ease off on the loud pedal and then get on it again and the 
power returns until the next ping.  I experienced this any number of 
times during trial runs while Mihnea and I were developing software 
for my S6.  Make that "while Mihnea was developing software for my 
car and I was burning chips and trying them for him".
