It looks like a lot of knock.

Retard the ignition 4 degrees everywhere for all tables and see if the knock retard goes down. If so, then you are over-advanced.

The Bosch ECU does not have very good knock control and you have to do it all yourself in the tables.

Hello.
I have not find on the forum explanation of how the ignition cards in FK8 now work.
Will there be a full explanation in the help and how to control the ignition?

Ок.
Question.
Ignition (In Cam +) = Ignition advanced?
Ignition (In Cam - ) = Ignition retarded?
How does the table work Ignition (In Cam - & Ex Cam + ) ?
Thanks

'In Cam' = 'Intake Camshaft'.

All the ignition tables are in degrees advance.

OK.
Last question.
Why the ignition angles in the tables do not correspond to the graphs of the datalog in the mode WOT?
I'm watching a "datalog0001.fpdl"
The picture above is a blue and red circle.

There are many corrections between the ignition tables and the actual ignition.
