Chris,

You are absolutely right, this will definitely prevent stalling. My trouble is during aggressive turning when I'm downshifting quickly while making a turn. A blip of the throttle prevents a stall, but sometimes I forget!

There's photo enforcement now. You'll probably just get your tickets in the mail...

Basic statistics state that your likelyhood of having a stall in a 95 with a LWF is pretty high. 13 out of 20 experience stalls so far according to the poll.

The problem is known and statistics are in favor of the possibilty of a stall. One could state, today, that you have a 65% chance of stalling by going with a LWF solution on a 95.

I wouldnt never say dont get a LWF to anyone. I like the performance but I dont care for the stall. There is the trade off, for some, in this upgrade. Yes, I know learned how to adjust my driving habits to avoid the stall (I know the lazy push at higher RPM's can trigger a stall) but sometimes you just cant, or dont, follow protocall. Its so much better to drive, relax, and think about anything. After 4.5 years of having the LWF, I know the reasons and conditions behind the likelyhood of stalling. Lights on, lights off, lights on in combination of AC, ect, ect. And most of the time I do but every now and then that little devil on on my shoulder says "do you think you will stall today?" Sometime that **** just pops up in ones head. If you have a 95 and get that occasional stall, you probably know what Im talking about.

This is heresy, but I honestly don't think the LWF is worth the hassle. You get some fairly loud gear rattle and the stalling issue. Did I notice a performance improvement? Nah, not really. Everybody hypes this up, but I think it's mostly a dud.

If I never had stalling, I might not be saying this, but IMHO stalling is just not acceptable in a street driven car.

If there comes a time when the clutch needs to be replaced, Im back to a dual mass.

I agree 100% that stalling is not acceptable in a street driven car.

I, too, think the performance benefits of the LWF are fairly modest . . . but you won't see me giving it up for a DMF. On the track, every little bit helps.

TheOtherEric

Sure, on a racecar it's a must-have.

There are some cars that really need a LWF, e.g. my 2003 Audi A4 and the 350Z. The 993 is not one of those cars.

mine stalled 4-5 times yesterday alone on the street.... it makes some pretty interesting driving at night.

Car stalles.
Turn key off, headlights turn off, pitch black, still rolling.
Starting car, headlights still off, Still pitch black, dont see where I'm going.
Engine starts, headlights back on, finally see where I'm going.
Yaaay, that was fun.

I came to a few intersections where there was so much wind noise I did not even realized the engine stalled until I went to take off and I look at my tach and its at 0 and all the gauge lights were on.... darn thing stalled again ......

I have to add the immobilzer factor into the mix of of things when I stall. I was experiencing the same issues as you when I firts had the LWF installed. Based on theory,research, and feedback, tweeking your idle with the lights and AC on MAY help matters. Maybe around 800rpms. If you havent chipped it, I would suggest a Rennsport chip.

I wonder why others with 95s are not getting stalls? Please share any secrets like idle speed or some remedy.

+1 Since being on Rennlist I haven't seen a good point made of having a LWF for a street car. IMHO

When was the last time you cleaned out your idle stabilization valve or ISV? It may not change anything, but it is such an easy DIY (even if you are not a DIY person) it's worth trying.

Steve Weiner has stated that a vacuum leak somewhere in a car will make it more prone to stalling. I had every conceivable gasket, tube, etc...replaced when my top end was rebuilt, and I still get the occasional stall.

The ISV was cleaned out with my 60k tune last spring. A block away from the shop when I picked it up, it stalled. It was just great driving off after doing about $5k in tune, misc fixes, and a suspension upgrade to only stall a block away. Which reminds me, I should clean it out again.

The consistency with the stall has been the same since day one--even with a cleaned ISV. I couldnt say its been any more or any less since the ISV cleaning. Sometimes it wont happen for weeks, sometimes back to back, sometimes a couple of times a drive.

Just one of those things I have at for years and just dealing with it the best way I can.

TheOtherEric

Cleaning out the ISV did nothing for me either. AFAIK, there's no reason that a Rennsport / GIAC chip should help with the stalling. Certainly didn't help me.

I have a 95 with a LTW flywheel and a Rennsport chip. It does stall, but only once very 6 month or something like that. What I noticed is that the car stalls only in ONE SPECIFIC situation. The car stalls ONLY if I am in gear driving, back off the gas completely while in gear, and then depress the clutch. In that case, the car RPM will drop freely and very low. The car catches this most of the time, but once in a while, it stalls.

What I suspect happening is that the ECU shuts off fuel supply when it senses the throttle is backed off. When clutch is depressed, the LTW causes the RPM to drop and the ISV is not able to catch it. I don't remember if the AC was on when the car stalls or not.

Anyway, recovery is pretty quick. Press clutch, put in gear, pop clutch!!! BAM!!! Car is running again.
