Clever. In fact, so crucial is it that they ought to simply put another
sensor on the other end of the crankshaft :-)

Never quite understood the change from VR sensors to hall effect. VR,
being simply a coil, are far more heat resistant than hall. Electronics
that can get up to engine heat never a good idea IMHO.


My sister had one go on her dreadful Meriva while we were all out
somewhere. Then it would run for a few miles and then we'd have to let
it cool down all over again. I'm guessing it was a potted thing that
started to crack with heat and age.

A far cry from my old Tiger Cub where you would just turn the
distributor until it sounded happy, then nip it up. :-)

But you wouldn't need to put it on the other end of the crank. Simply on a
different part of the toothed wheel and compensate in the ECU.


Silly me :-)
