johnny69 Posted August 23, 2023 Report Share Posted August 23, 2023 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 Quote Link to comment Share on other sites More sharing options...
Vaughan Posted August 23, 2023 Report Share Posted August 23, 2023 a copy of your tune and a pc log would make this easier to diagnose Quote Link to comment Share on other sites More sharing options...

Adamw Posted August 23, 2023 Report Share Posted August 23, 2023 You dont have any knock trim tables assigned to cylinders. Quote Link to comment Share on other sites More sharing options...
johnny69 Posted August 23, 2023 Author Report Share Posted August 23, 2023 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 Quote Link to comment Share on other sites More sharing options...
