My cars do not get driven very much but usually the first time I go WOT I get knock.
I run alky and the cars are up to normal operating conditions before I go WOT.
I will usually do several more WOT blast and will get no knock.
Does anyone else experience this condition?
This is not a substained knock.

try pushing the test button once before you stand on it...sounds like the alky is draining back...or the line has been sucked dry the first time you hit it.

What is the scan tool showing?

Is the knock going up or down? ie. 1*-2*-3* or 3*-2*-1*.

Because you may be developing false knock.

Hitting the test button was what I had in mind as well.
On one car, I attached the alky line closer to the IC than the TB.
Could this be a problem?
