I'm not using the knock sensors, KMS doesn't have a facitily for knock sensors. If the engine is mapped correctly you shouldn't have a need for knock detection. KMS has fuel correction for air and exhaust temperature which should help keep things safe. I've mapped mine upto 5000rpm, with around 7psi...
