I was going to post these on the cobbtuning forums but they seem to have closed today. I've had a gander or two at the tuning guides available here and there but I'm just seeking more wizened opinions regarding knock management. If you have the knowledge/experience and the kindness of heart to take a peak at a couple third gear pulls and tell me what you think I'd gladly appreciate it.
Stage 2 with 3-port EBCS with WGDC table values multiplied .7
Basically, I've been having issues with knock as the DAM continues to drop after reset and the ECU pulls boost. Replaced knock sensor to no avail. I heard a rumor that the uppipe heatshield can sometimes rattle at the specific knock related frequencies with a modified downpipe. Going to replace the uppipe later this weekend just in case, but I have a feeling that isn't what's causing this.
The first two logs I hit close to the boost targets, but somewhere in between the end of the second one and midway through the third, the ECU pulled to mechanical boosting.
So any suggestions to keep this from recurring would be greatly appreciated. Do I retard primary ignition timing at the loads/RPMs where fine knock learning values are negative? Change fueling tables? Decrease/disable knock sensor sensitivity and boost it to 18 psi? Sell it and buy a miata?
I got some logs and I'm a dummy.
