Ibought the Accel 300+ ignition wires that fits a 1999-Present Buell,Dyna Partnumber175097 to change back to black from orange wires rode home less than 3 miles and readon this forum thatthis might cause problems with the knock sensor on a new bike, I am to **** about the bike so took them off. H-D did not have a answer, one parts guy said not to run them and the dude next to him at the counter said the first was crazy and go for it. What do you guys thinkam I OK run them? they cost me $29.00and hate to feel like I pissed the money away. I am back to running S.E. wires now. Thanks, Jeff
If you want to run em, run em. You wont do any harm, the worst you will get is it will throw an error code with the engine warning light. If that happens just change back, but I strongly suspect you will be ok. The problem arises because some wires and plug combinations fool the ecm into thinking you have pre-ignition or knock as you say. It dosent mean you have a real problem but the ecm just thinks you have.

That`s impossible. Wires and plugs have no direct relation to the ECM. The ECM controls spark signal to the coil, but reads pre-ignition through the knock sensor. This would need to be an actual fault(spark-knock)to be detected.
Wire resistance will cause misfires due toincompatibility issues. The ECM has no way of knowing what the resistance of the wire or plugs are. It detects misfires by reading crank signalswith the crank sensor. No ignition signal feedback to the ECM is available beyond the knockand crank sensor signals.

drdiesel does that mean I'm OK?
If you have no misfire problems, I would say yes. Get an OHM meter, check the OE and AM wires to see if they are the same.

How familiar are you with "Delphi's Ionization Current Sensing Ignition Subsystem" (i.e. "no sensor knock sensing")? It uses the plugs/wires to take measurements immediately following the spark.
