Knock light visual display

Hi, I've just wired in my new G4 knocklink visual diplay and its showing det when VTEC comes on.

My setup is a 2L DOHC VTEC turbo. Compression ratio has been reduced with a 2MM cometic headgasket and is sitting around 9.5-9.7:1.

My problem is that when vtec comes on the light shows detination but you dont here it on the knocklink headphones. The car is being road tuned so the timing still needs some attention. At the moment when vtec comes on the timing is set at 20.5deg btdc and 6psi of boost from vtec activated from 5800rpm to 7500rpm and the light flickers the whole time. A/F ratio is 11.7.

I am wondering if the knock light is picking up the extra noise the valve train is producing when vtec is turned on and thinking it is knock? Has anyone experienced this problem and is the a solution for me to sort this out.

Im stumped. Thanks for any help.

Corey
