mines a '93 wrx, just wondering what knock voltages are classed as high?

noticed when I turn up boost on the avcr, the car feels like its holding back!

wondering whether the ecu (standard chipped) is picking up knock and pulling timing.

so if I monitor knock sensor voltage whilst setting boost I'll have a better idea of what is going on.

cheers guys
Mark.
