as LMB said you have 2 routes. wait til it fails or just do it. I took the later since I like to go on road trips.
definitely try the SRM mode with the manual. you'll be amazed how awesome it is on the down shifts. ie @60 clicks drop from 3rd to 2nd and listen to the music  |
If we look at a vehicle that already has the Zspeed, I'll definitely ask if the clutch is OEM. If it isn't, before doing anything, I'll come back here and ask.
Depending on the asking price of the vehicle, I suppose we could add on the cost of the Zspeed and see if it makes financial sense to go further. I understand that Nissan might even be willing to do the job of installing it rather than their own part. If the slave problem is as extensive as it seems, maybe they've got a NASCAR pit crew all trained up to do the job in an hour...............while blindfolded. I can give a local Nissan dealer and other shops a call to get an estimate for the job, including new master cylinder.
If the OEM slave is certainly going to leak at some point down the road, I would think that installing the Zspeed
before the slave starts leaking might make more sense in case the fluid ruins the clutch plate, no?
As I said much earlier in this thread, I am intrigued by the rev match feature. How does whatever computer that controls SRM "know" what gear you're going to shift into? It can't. So it must have to wait until you actually put the gear lever into a particular gear's slot and
only then,
even before you are able to lift the clutch, increase or decrease engine (flywheel) rpm to match that of the clutch plate.
If so, this is quite a trick, because it doesn't take long for that left foot to come up when you're going for broke. The SRM computer must have continuous, instantaneous control of engine RPM at all times (at least when the clutch pedal is going down),
regardless of how your foot has adjusted the accelerator pedal, correct?
So, AFTER the rpm-synchronized plate and flywheel have come together, does the position of accelerator pedal instantly take/regain control of engine throttle/rpm? That is, say you lift your foot completely off the accelerator
after you depress the clutch. What happens if you then make a gear change and you lift up the clutch? Does the computer still synchronize engine rpm for the mating,
regardless of accelerator position, but then, after the mating, instantly allow the accelerator position to take control of the throttle/engine rpm?
BTW, is SRM something that is always on until you turn if off, or is it always off until you turn it on?
Thanks.
