| If the standard ignition system is yer actual good 'ol
distributor/points type stuff....... you probably couldn't find
a more reliable electronic system than Lumenition.

| I do not mind if it's a capacitive discharge, inductive or a simple
transistorised type.
Can you give more information on the Lumenition you suggested? Since
it still uses the points, it's probably a capacitive or transistorised
type. What's the price and where is the source of this product? You
see, I'm from Malaysia and there are so many makes and brands here that
one can easily get confused.
I'm looking for a reasonably priced and reliable product. And I
would't want to go back to Volvo - theirs would cost a bomb.

| Lumenition doesn't use the points, but it fits on the type of
distributor that has them. I'm not sure of the exact details, but it works
by having a disc mounted on the distributor spindle. The disc has holes,
through which a light shines. A sensor picks up the pulses of light through
these holes, which the EI unit uses to pulse LT through the coil.
It has the advantage of being simple, as the advance/retard of the original
distributor is used. A more complex system would need its own vacuum and
engine speed inputs, and probably isn't worth the hassle...

| 1151.4 | More on Lumenition | VANDAL::VANDIK::HENNEMAN | Westfield VAN Driver | Wed Jul 18 1990 10:35 | 18 |
| The Lumenition system actually uses a four (or six, or eight - depending on no
of cylinders) bladed rotor, a bit like a fan, that fits on the distributor
shaft beneath the rotor arm. As the shaft rotates it cuts an infra red beam from
a transmitter/receiver umit that also fits inside the distributor body. The
pulses generated go a a control unit, which in turn connects to the coil which
makes thhe HT in the normal way.
The nice thing about it, is there are no wearing parts, so dwell angles never
change due to lobe wear, contact arcing is a thing of the past, as is bouncing
at high revs. Lotsa engine tweakers who up the rev limits by 2-3K rpm use it
for just these reasons, in combination with a comp distributor.
They make various permutations of all the bits and pieces for just about every
distributor around, with prices from �60-�100. I have the list at home of all
the various distributors that they do kits for, so if you post details of your
distributor (not car), I'll let you have the details of the bits you need.

| The only reason that I recommend the Lumenition specifically is
because it has been on my Ford Granada for 13 years without a hitch.
Can't say what type it is but the points are replaces by a chopper
blade and source/phototransistor pair that replace the points.
I haven't had to adjust the distributor for the last 7 years and
the plugs only get replaced once a year because my wife uses thae
car for a lot of stop start town driving; if you can get your hands
on a UK car mag I am sure that it will be advertised.

| 1151.6 | Time out but to be back later. | MSAM03::DANIELWONG | | Thu Jul 19 1990 03:41 | 14 |
| I'll find out details of the distributor and let you know, Dick.
But isn't the volvo's distributor the same as the UK models? I believe
the Volvos 244 and 240 have the same distributors here, except for the
240 year 1987 or 1988 onwards when they introduced EI in their cars.
Thanks for all your inputs, i shan't be able to reply until 24th July;
cos' we are having a long holiday here the next few days.
Best rgds
