I believe that the 09s don't light up when det sensor is pulling timing/ adding fuel like earlier sleds. But it's reaction is severe enough (a good thing) to protect the engine that you should feel the power drop.

^^Yes, it is the DET sensor/check engine light. It blinks every second when you have a lean condition, usually from bad fuel.
Lean and detonating are 2 different things.
If it's lean it will detonate, so what's the difference?
Not necessarily, I'll let someone else write the book, my answer will be short. Detonation is actually pe-ignition. This means the mixture starts to burn too early.]
Pre-ignition often leads to detonation but is not detonation. Pre-ignition is caused by an ignition source before the spark occurs. Hot carbon or glowing piece of metal(broken plug thread or too hot of spark plug for instance).
Detonation occurs when excessive heat and pressure in the combustion chamber cause the air/fuel mixture to autoignite. This produces multiple flame fronts within the combustion chamber instead of a single flame kernel.
......and those flame fronts pound and pound on metal parts before the mixture was meant to be burnt, a lean condition does the same thing doesn't it? .......burn before it is meant to, pounding on the piston, bearings, rods, crank, etc. correct? Detonation is "knock", won't the motor knock from a lean condition?
Let me put it this way, if the fuel/air mixture is lean, does it still burn at the correct time, but just too fast(heating up all the parts and stressing them), or does it burn too early like detonation? Just when I thought I had it figured out you guys throw me a ringer. I like to learn though so I don't mind. :beer;
So what about getting the light operational? Anybody done it?
