Hello,
I donnīt know if it could be a det or not (another sound??)
I have a knocklink in a MY98, and when 4500-5000rpm I see the orange lights and 6000rpm I see de big red.
It happens always, with load or without load, with boost (0'9bar) or without boost (0'5bar), with the neutral gear too.

Any idea of which it happens??? Really det?? Spark plugs?? Piston??

Thank you for your help.

(Sorry for my poor english)
