Ricky, the lightened flywheel throwing cel's in nonsense.
Physically, it cannot throw a cel.
The mass has nothing to do with the fact a sensor will read it or not, it still spins at the same RPM, and it is the same diameter, it will not do anything.
Our cars are notorious for throwing cel's especially the misfire code.
It just happens every once in a while.
I can argue about flywheels for hours, in the end, i wont get one because its a lot of cash =)

I was thinking about the flywheel situstion you guys keep bringing up. I could see where you would get a code. If you screw up and through things off balance, it will cause a code. But if you actually do it right, there won't be a problem. And yes, our cars are notoriious for codes. I get them at the track just from overboosting. That's using a stock turbo and OTS Cobb Map.

While the performance characteristics of a lightweight flywheel seem to be the perfect solution, there are compromises:
a. Low end performance is affected. This usually means that higher revs are necessary for smooth starts due to the reduced rotational mass. For drag racers, this can be a BIG issue.
b. Possible missfire check engine light.
What causes a missfire CEL with lightweight flywheels?
No one is really sure. There are theories though. One theory is that the Crank Position Sensor senses the rotational speed of your crankshaft. Since a lightweight flywheel reduces the rotation mass of your engine, your crankshaft accelerates and decelerates quicker than OEM specifications. Another theory is that there is a missmatch of information from your Crank Position Sensor and the Cam Position Sensor during acceleration and deceleration. This may or may not be caused by the slow reaction of the belt tensioner which will cause enough belt slop to give erroneous readings to the ECU. Since missfire CELs (due to lightweight flywheels) do not occur as often on the STi and the STi has two Cam Position Sensors, this adds further evidence that the missfire CEL has something to do with the Cam Position Sensor since there is only one on the WRX.
