Re: What is everyone's opinion on lightweight flywheels?

No because the ecu shuts off fuel above a certain rpm when you let off the throttle completly and with the light flywheel it comes down faster than the ecu anticipates and stalls before the ecu starts firing the injectors again.

Not 100% acurrate, but close. The injectors fire again before the car stalls, just not soon enough to catch it. You can raise the rpm and fuel cut limits in DSMLink to help. The thing I noticed also is that the ISC does not come back up enough to catch the engine either. Using the FIAV/ISC block-off would help keep the correct amount of air going into the engine so once fuel is back the engine would not stall as easilly.
