Knock Readings

[Parker]

Hi,

I've had a PFC Djetro installed in my GTR for a while now and have noticed a slight change in the knock readings i am getting.

First tune i would get readings no higher than 40

Current tune i will get readings below 30 and then every now and then one will be in the high 30's.

I have heard that the PFC sees a reading of 60 or more as a genuine knock event and in that event am i being anal worrying about something 2/3rds of that?

I have also noticed that the higher readings i get are not when the car is at full load but when i back off the throttle or at odd moments. Got any theories why this is?

Car gets another tune tomorrow (because boost control has been problematic a new EBC gets done tomorrow) so i'll see if things change after then.

Cheers,

Ryan.
