Question LWF in a 964

I just read Riccardos' post where he questioned the fact that a car he was looking at had a dual mass flywheel installed, and lamented that a LWF was not used. There seems to be a group of us who have had running problems with the LWF, and other who have not had any problems. I would like to check something: The 90, and I believe 91s had only one hall effect sensor to read engine position to pass on to the DME, whereas the 92- had TWO hall sensors. I would like to poll those who have LWF and either have had problems, or have NOT had problems and correlate to the years?

Hi Horst,

Original DMF failed in my car at 34k miles, and had an RS LWF installed: stalling and erratic idle. Hated it.

Had the LUK installed at 50k miles. Much nicer. The car is at 107k miles, no flywheel problems.

A 1994 C2 I am considering getting has a LWF on it and the thing will idle erratically all of the time, even stalling. Supposedly, the fix is a modified idle stabilizer valve and a custom made chip. Steve Weiner can sort it all out, but it is a pain as is with the odd idle and stalling

The current owner did it for performance gains, as it had yet to fail at 70K miles!

My 93 RSA has the lightweight clutch and flywheel. After it has been driven and parked, when started again the engine has a tendancy to "hunt" for the right RPM range. It has stalled on me a few times, only after restarted with the AC on. I just received a new autothority chip re-mapped to take care of the problem. I'll let you know how it works. It does have two pickups on the flywheel, my mechanic mentioned that they could be adjusted closer to the flywheel, I don't know if that is a factor.
