Quickshift Sensors - linear or rod?
Anyone fitted either the rod or linear sensor? If you know what I've just asked, without further explanation, then you'll probably be able
to help.... please.
I've had a linear sensor on one of the gearchange bellcranks, works with some reliability, though cut point in the change could vary a tad....
probably a bit of slop/vibration, but nothing obvious. My new car has a PCIII and a cable shift...
I've got the offer of a push-pull sensor that simply plugs into my PCIII. The sensor will simply slot into the gearchange cable end. Simples.
Before I take the plunge though, anyone used a push/pull sensor - how much effort do they take to contact, and is that effort appropriate to kill the
fuelling at the right time on a BEC change?

I've got a Trickshifter (http://www.trickshifter.com/shifter.html) which I believe are now sold under a slightly different name with a few more
variations (in terms of functionality and cost).
As you can see on the link it uses a sensor which you pretty much have to make part of the linkage - that's what I've done anyway.
So I can only comment on how it works in that fashion - not sure if it could be made to work satisfactorily with a cable change and also not sure how
this compares to the "push pull" PC3 sensor.
The way the trickshifter sensor works is detecting either being compressed or stretched (probably a strain gauge?). It doesn't actually move a
visible amount when being pushed or pulled.
It is adjustable via a grub screw (with locking nut) on the top.
Works really well.
Also this system cuts the ignition rather than the fuel I believe so can make some rather loud bangs on changes in higher gears when you're
"on it"!

Thanks, yep, although the visual appearance of your sensor looks like a linear version, it appears from what you say, to be operating as a push/pull.
I'll take that as a positive view on latter. Thanks, much appreciated.
BTW: The catalyst in the exhaust is making the can glow orange as it is, I think an ignition-cut explosion would be even more dangerous for the
marshals! Fuelling cut looks better for my purposes.
