I recently got a new tune for the boat. First time logging in awhile. I look and I'm getting some KR. 3-4.0 =O! Tuner agreed it was no good. First, I suspected fuel, but was reminded about the Chafed Knock Sensor wires. I didn't see any chafing, but for good measure, I put some wire loom and electrical tape on them. I also changed my plugs with some fresh Motorcrafts gapped to .030. Went out and did a pull, still saw 2.0 KR on the sensor in the log. Went and threw in some race gas and teleported to Mexico! Did a pull from 2-5 and I must say, not only is the car running well, by butt dyno, logs seem to agree.
Logs are attached.
