Super Knock code

[SlowE93]

Any update on this I started getting superknock codes as well. FBO with RB turbos..upgraded LPFP, Index 12 injectors. Could this be due to a HPFP that is bad or is going bad?

It just comes and goes...another member would get it if he pushed over 600whp....but at 600 he was good. I get it when weather is 50s°F...when temps warm up, no issues....really weird.

In my experience technical issues that mysteriously come and go with temperature variations tend to be caused by something electrical in nature. I’d check wiring, grounds, sensors, etc.
