Can anything out there get a readout from the OEM knock sensor? I know uprev can't.

I suppose folks could try a J&S safeguard.

Well it's definitely not going to be able to pull timing if it's before the charger because the MAF is thrown off from the get-go. You're throwing an obstacle in-front of another.

If you don't want to go with the HKS knock amp system then the AeroForce Interceptor should, as long as the ECU supports it (which it should).
