If you use the GT3RS clutch and flywheel, do you have to flash the motronic to compensate for the lighter flywheel. On the 993's the engine would die when you came off throttle to a stop as the motronic expected a dual mass fly wheel to keep the motor spinning as it switched to the idle circuit.

 

Uh....No!

 

with the gt3rs flywheel does it chatter at all when idling?

 

I was told that it does.

Yes, it does with the clutch disengaged...and it gets loader with the AC on, but I have gotten used to it and it does not bother me at all (especially with the tunes cranked)...and I'm in a cab!

 

This is a VERY good question. My car for a while would stall almost all the time. between upshift downshift or anytime the car was blipped in neutral.
I had the REVO stage 2 software "tweeked"and problem solved. I think what you mention was the problem.
I dont think all cars will see this however so no mass panic. Also I think the fact that my car has straight pipes off the turbos also had something to do with it.
