Timing light on the balancer reads from 0 to 10 degrees advanced. TunerPro says everything from 14 to 27 degrees of advance based on RPM and other parameters. Last evening inserted 3.3 Kohm resistor in series with knock sensor wire to ground. Measured DC and AC volts. DC was 2.1 and AC was low millivolts which is very good. Routed the knock sensor wire away from spark plug wires. Suspect they have high EMI radiation level inducing noise into adjacent wiring. May reroute TPS and MAP wires also. Would like to replace with twisted shielded cable to keep EMI noise out.
