Fuel Injection Notice

          Some fuel-injected models may experience the engine light intermittently coming on. This condition is caused by the neon wires having a "different” resistance than the “stock” wires. This "difference" is not a problem, but is just that, "different" than stock.
           The reason this happens only on fuel-injected models is as follows: The Harley Davidson engineers had this wonderfully powerful new computer on these models anyway, so they thought they would incorporate some "cool extras" into its’ on-board diagnostic functions.
           The fuel-injected models have a fourth wire in the coil, which carburetor models do not, called the ION Sensor. This sensor measures the resistance in the ignition wires at high load and at high speeds. It basically checks the wires, as you ride, to see what condition they are in. The computer, being just that, a "computer," lives in a world of 1’s and 0’s. It must have pre-programmed limits to look for, and only knows what its’ program tells it is “okay” or "normal." Being that the neon is much more efficient than the stock wires, it will show as an "open" when checked with only 12 volts. The reading for their resistance falls outside of the computer’s programmed limits. This is not necessarily a bad thing, just outside what the computer was told to look for as “normal.” Hence when it sees these more efficient wires with a "different" firing resistance, all it knows is that it is "different" from what it was told it should see.
           So, it turns on the light to let you know it saw something "different." This can happen even when you change wire brands that don't have neon in them, such as solid core wires or steel braided cables. This function of the ION sensor and computer is for "Diagnostic purposes only" (as stated in the Harley Davidson Fuel injection manual part # 99498-02 on page 5-67). Which means that it is only for the purpose of checking the wire and secondary coil resistance and condition.
           The fuel-injection computer does not use this signal to set or adjust any of the operating parameters of the ignition or fuel-injection system form these readings. That is why it does not affect the way your bike runs, nor will hurt your bike in any way. This is what is meant by "Diagnostic purposes only." It is also why non-fuel-injected bikes and have no ’check engine light” issues. They have the same motor and hard parts as fuel-injected bikes, they just don’t have an ION sensor.
           We hope this explanation of just what is going on and why, will show you that there is "No Magic" to ignition neon, just science. We also hope after getting the real reason as to why this is happening from us, as opposed to the lame explanations given by other companies and by uniformed technicians, it will show who really knows what is going on in the neon ignition world, and who is just winging it.
