my engine is pinging like a mofo under load at low rpms. i tried using octane boost and it reduced the noise but not by much. the current compression is 12.5:1, if i lower the compression can that stop the damn pinging? and how would i go about lowering it. im using a p28 ecu which doesnt search for a knock sensor, if i use the p72 will that help at all???
any suggestions please! thanks~
