There is good news though, I think I found closed loop target tables in the ECU.. working on it for the next few days.

And here is the theory behind it from the Innovate forums

It seems to be plenty lean at idle and low load.
It's admirable how Klaus replies and participates on the Innovative forum.

even lower on my display. The lower readings are not consistant however.

Anyways, the reason with my little story is to setup a question.
Since you use EVOScan and the knock buffer, have you seen any correlation??
Like when the knock buffer shows a spike way above the noise floor, does EVOScan actully log any knock count???

I was thinking about getting a knock buffer in addition to EcuScan.
