Default Detonation. Yeah!

Neat, my car is detonating at 10-12 psi.

The car is not overboosting and I just had the mixture set a month ago. Hmmm.

Timing off maybe? What else to look for?

Can't find any vacum leaks.

I haven't checked timing yet or pulled the spark plugs. I'll do that tommorow.

I'm so disgusted with the car right now

Is it throwing the CEL (blinky blink)? Could just be a faulty knock sensor.

What does detonation sound like? I've heard it sounds like a pinging sound but I've never heard it before?

How much do those knock sensors go for?

Default No CEL...

How would a faulty k-sensor cause pinging?

I'd guess that if the knock sensor were inoperative it wouldn't tell the ECU when the engine began pinging (detonating / knocking). Therefor the ECU wouldn't retard the ignition timing and the engine would be free to ping under conditions of high load / high boost.

My WU engine has no knock sensor, so this is mere supposition.

Check your plugs first. What plugs are you running?
