Audi S3 1.8T No knock ign trim with knock present?

[johnny69]

Good afternoon 

Setting up knock control for the first time on a Link G4X Audi plugin, I'm having an issue where the knock level is greater then knock threshold, knock counts start going up, but I never see any ignition trim? 

Current settings 

- Normalized Ign  

- 7khz narrow band

- Ignition retard gain - 2.50 degrees/knock

- Ignition retard limit - -5.0

- Knock trim gain - 1.00

- Knock threshold - 1.40 (Set low to test, usually 2.0)

Once again first time setting this up, so I know its probably something I'm missing, have used various setting from similar threads and I'm happy with how the ECU is detecting knock, but need to see some trimming before I get further with the setup.

Away from my laptop currently, but will try get a copy of my file up ASAP. 

Any help would be much appreciated

a copy of your tune and a pc log would make this easier to diagnose

You dont have any knock trim tables assigned to cylinders.

Turned these off yesterday to test, as I thought it may just globally remove spark with no allocation.

But re reading the help browser I think that maybe my issue. I didn't realize this was a retard table, thought it was a gain table 

Thanks Adam
