Are you sure the knock sensor in the block is working and undamaged?

Have you discussed this with your tuner?

Do you have forged pistons?

If you are using a P30, the knock board is tuned for a B16A engine and not an H22. That could also be the issue. With some research there is information out there about the resistors on the board that will tune it for the H22 instead.
